Android app

The Android app lives in Apps/Android/. It is an early phone shell: pairing, HEVC/AVC live view, GPU looks, scopes, camera writes, and media. The public beta on Google Play is open — join the Android beta. iOS is the daily driver. arm64 phones, Android 10 or newer.

If pairing or live view fails, tap Report a problem on the pairing screen or in Operator Setup → System. It works before your first successful pairing; technical details and a reply email are optional. For a local diagnostic export, use pairing’s overflow menu → Share Diagnostics or System → Diagnostic options → Save diagnostic report. Local VPNs and ad blockers (AdGuard, Blokada, RethinkDNS) can block the UDP live feed after Wi-Fi joins — pause them or exclude this app (Troubleshooting).

Before pairing

Before pairing, turn off DJI Frame Tap and force quit DJI Mimo. Frame Tap blocks any pairing or connection, and DJI Mimo on this phone or any other phone near the camera can hold it. The first pairing step shows this as a tip. After 20 seconds with no camera, Still looking repeats it: “Turn off DJI Frame Tap and force quit DJI Mimo on every phone near the camera. Make sure the camera is on and activated, then move closer.” When the camera never answers pairing or the video link, the error message ends with the same reminder.

Permissions

Pairing asks only for what finding the camera over Bluetooth needs: Nearby devices on Android 12 and newer, or Location on Android 10 and 11 (which also need Location turned on to scan). Precise Location is asked later, in Wi-Fi and Hotspot setup, to show which Wi-Fi this phone is on; only the network name is read. Joining the camera’s Wi-Fi needs no extra permission. If Android no longer shows a permission prompt, the pairing screen’s Open Settings opens this app’s page in Android Settings (Troubleshooting).

On Your cameras, PAIRED and NEARBY groups separate remembered cameras from new discoveries. Select a camera to see its connection progress and Cancel. Pair new camera opens the guided flow; select a discovered camera, then Continue. Media and Settings remain available without connecting.

Field Monitor interface

The camera battery gauge shows the percentage reported by your Osmo, or a dash when unavailable. Top capture settings, STBY and timecode align in one row; Lock matches the Settings and Media button size. The live signal indicator uses the Link Health colors from Settings: red for Poor (0–1 bars), orange for Watch (2–3), and green for Stable (4).

The native UI uses Sora typography, cyan controls and dark panels. Camera readouts have a layered dark glow for contrast over bright footage. Outer monitor controls sit close to the screen edges while retaining cutout clearance. In portrait, STBY, timecode and REC SETUP share a row below storage and battery indicators. Live view and photo/video playback hide both Android system bars; swipe from an edge for temporary access. Playback has a visible Back/Close control to return to Media. Other pages hide the status bar but keep Home, Back and Recents available when your phone uses button navigation; gesture navigation follows your phone settings. Controls leave room for the navigation bar and camera cutout. Portrait phones place exposure values in two rows above the system buttons; landscape puts those values along the bottom of the picture. REC SETUP opens capture format, color and shooting options from the top of the monitor. Portrait keeps Format / Color / Mode tabs on the details drawer; landscape has no extra category row. Landscape shows the shooting mode immediately after the color profile in the top row, including narrow phones. Photo shows its mode in the top row. ISO, shutter, white balance, focus and audio stay along the bottom and remain visible while a top picker is open. Auto exposure keeps EV as the value and shows the camera-reported applied shutter under it (EV 1/200s), updating as Auto adjusts exposure. Missing or unsupported shutter data leaves the caption as EV. Tap a value for the full details drawer; hold or drag for a compact dial. Lift to apply the selected value. Camera controls hold your selection while the camera confirms it, so an older status update does not briefly move the dial back. A rejected or unconfirmed change returns to the reported camera value after settling. Long-press the picture without moving (about 0.6 s, after the haptic) and lift to lock exposure while exposure is Auto: the focus box turns yellow with an AE-L tag, and a sun-and-open-lock key beside the focus recenter button returns exposure to Auto (in portrait it sits at the left, beside the View Assist tools). EXPOSURE reads AE-L while locked, and its picker lists AE-L left of Auto: choose Auto to return to Auto, or Manual to keep the locked values as ordinary Manual. The lock switches the camera to Manual at its current Auto ISO (nearest whole stop) and shutter; changing shooting mode or an Auto report from the camera also ends it. The haptic only comes when a lock is possible; a hold in Manual or while locked is silent. Dragging after the hold still draws a tracking box. White balance Mode and the WB tile’s drag dial offer AWB Lock beside Auto while Auto reports a live Kelvin; it sets Custom at that Kelvin, snapped to the Kelvin drum, and keeps tint. While locked, WB stays on AWB Lock (the tile reads AWB-L); choose Auto to return to Auto or Custom to keep that Kelvin as ordinary Custom. A WB change on the camera also ends the lock. Neither is a camera-native lock and both await hardware testing. Use the top shooting-mode control in landscape or REC SETUP → Mode in portrait. Record and the Photo shutter have no shooting-mode long-press shortcut. In Photo, the capture control becomes a shutter and takes a photo immediately, without recording confirmation. Photo and camera-reported Live Photo hide video color-profile, frame-rate, codec/bit-depth, timecode, recording-duration and audio controls. White balance, ISO, EV, shutter speed, focus, zoom and photographic assists remain available. Video-only panels close when the camera changes to a still-photo mode, and returning to Video restores the relevant controls without resetting assist preferences. Pocket 4 Pro Slow Motion labels 200 fps as 200p, including the 3× lens’s reported options; available rates follow the current camera capability list rather than a fixed wide-lens maximum. Low-Light / SuperNight retains start/stop recording. Changing modes clears stale format choices. A pending recording confirmation is dismissed if the mode, recording state, connection, or interface lock changes. Shooting-mode access in both orientations and Video/Photo switching have been checked on a Galaxy S25 with Pocket 4 Pro. The full specialty-mode matrix remains outside that check. In portrait, Settings and Media remain usable with a picker open; returning to the monitor restores that picker. Camera values use two complete rows in portrait and one row in landscape. Assist palettes stay below Settings, Media and assist inspectors. In an inspector, scroll the preview and options together; LUT exposure and split comparison remain pinned below the scrolling catalog.

The View Assist palette collapses into the lower-left control area. Expand it for the full catalog; tap a tool to toggle it or hold to open its options inspector. Playback uses that same live-view slot. Video playback places its filename, metadata and source label above Favorite, Info, Share and Delete (when available). The timeline sits above Back 15 seconds, Play/Pause and Forward 15 seconds; landscape places the other playback options in that same row. Side arrows change clips. Photo review keeps Share/Delete at the top and Favorite at the bottom, matching iOS. On Pocket 4 Pro, tap zoom to alternate 1× and 3×; double tap for 6× and 12× when digital zoom is available. Other cameras retain their supported zoom stops. Hold the zoom value for a continuous dial. Its limits and recording restrictions remain camera-specific. Gimbal cameras expose Mode, Speed, Ramp and the existing experimental Motion Control editor in a wider trailing drawer. Mode, Speed and Ramp each have a tab with their own dial; the Motion Control action stays visible. All three waypoint rows show the reported pan, tilt and zoom, or Not set. Tap outside to minimize the editor without activating the controls behind it. Until dragged, the editor stays centered when the screen rotates; a manually placed editor keeps its chosen position.

Operator Setup → Display includes HDR display (off by default). It uses this phone’s HDR panel so live view, scopes, settings, media, playback and on-screen type stay readable in sun. It does not change the camera’s HDR/HLG color mode or the file on the card. WAVE and HISTO still measure the decoded picture. Turn it off indoors; extra brightness uses more power.

Operator Setup and Media use a navigation rail in landscape and scrolling tabs in portrait. Settings groups use compact information buttons beside their labels; Controls groups touch safety, gimbal options, and the on-screen joystick separately. Use Android’s system Back button or back gesture to return from Settings, Media library and pairing. These pages omit the large in-app Back button. Photo/video playback hides system navigation and provides its own Back/Close control. Back dismisses the current overlay or selection before leaving its page. Contextual Close and Cancel actions remain available. The bottom of the Media sidebar holds one row with Grid and List buttons and Small/Medium/Large sizes; in portrait, these controls stay at the bottom of the page. Filter uses the same chip as Sort. The filter card stays fully on screen, including next to a display cutout and above the navigation bar. Set a start and end date with the calendar, and filter by log/colour profile when that profile is known for a clip. Pull down on the library to refresh. Hold a clip to begin selecting, then drag across clips to select a range. In selection mode, swipe up or down to scroll without changing the selection, or drag sideways to select a range. Hold a clip to sweep in any direction, including near the top or bottom of the gallery to autoscroll; lift your finger to stop. Selection circles appear only while selecting.

Media retains favorites, cache state, playback assists and the existing delivery actions.

View Assist favorites match the live system-button size and remember which tools you actually use (saved on the phone). Collapsed, landscape keeps two favorites and portrait keeps one, under the arrow. The expanded catalog uses those same cells. Tap the arrow to open or close, or press and drag it so the expanding edge stays under your finger; a flick finishes the motion. In portrait, drag upward to expand and downward to collapse. Pausing holds the edge steady; changing direction moves it back with your finger. Locking the monitor cancels a drag and collapses the palette. The landscape expand arrow accepts taps farther to its right, with the toolbar anchored in place.

Anamorphic Desqueeze

Use DE-SQ in View Assist for an anamorphic lens or adapter. Tap to toggle; long-press for Anamorphic Desqueeze options. Choose 1.1×, 1.2×, 1.33×, 1.5×, 1.6×, 1.8× or 2.0×, or select Custom for a 1.00×–2.00× slider in 0.01 steps. Custom remembers its last value when you switch presets. Horizontal widens the picture; Vertical corrects a rotated adapter. The full corrected picture fits within the display area. While DE-SQ is on, portrait Fill is suspended and its control is hidden; switching DE-SQ off restores your saved Fit/Fill choice.

Desqueeze works in live view, video playback and photo viewing. Video and photo playback share their own on/off choice, separate from live view; factor and direction are shared. In the photo viewer, tap DE-SQ beside Favorite and hold it for options. Settings persist between launches. Desqueeze starts off; the initial factor is 1.33×. New DISP 2 pin preferences include it, while existing saved pins stay unchanged.

LUTs and picture warnings follow the correction, and framing guides align with the corrected picture. Desqueeze changes only the display: recordings, shared files and scope measurements keep the original image.

Mirror

Tap MIRROR in View Assist to flip the monitor; long-press for its options. Horizontal flips left-to-right for a camera pointed back at you and is on by default. Vertical flips top-to-bottom. Turn both on to turn the picture 180°, for an underslung camera such as one on a car mount. Tap to focus, drag to track, focus and face boxes, and the LEVEL roll reading follow the flipped picture. Mirror changes only the display: recordings and scopes stay unflipped, and Vertical leaves the joystick directions unchanged. Video playback uses the same axes with its own on/off choice.

Level

Enable LEVEL in View Assist to see how level the picture is against gravity. The reading comes from the camera’s own attitude sensor, not the phone.

• Two slim meters, laid out like a Nikon Z virtual horizon, show roll along the bottom of the picture and tilt right of centre, the same distance from the middle of the picture as the roll meter. A short bar crosses a slim dark band to show the angle (full scale ±8°), with small notches marking level. The line, bar and number turn green within 0.6° of level.
• Within about 25° of pointing straight down or up, the meters give way to a round bubble level: a bead that is amber off level and green within 0.6° of plumb. Use it for top-down shots.
• If the camera stops reporting attitude, the meters show a dash and No level data. They never turn green without data.

Tap LEVEL again to hide it; the on/off choice is saved. LEVEL is not shown in playback.

Double-tap Level

In the gimbal drawer, Double-tap chooses what a double-tap on the joystick and Circle/B on a game controller do:

• Recenter (default): the camera’s own recenter, relative to the handle.
• Level: one move to the nearest world target, which is the horizon, or straight down or up once the lens is past 45°. A toast says Leveled to world, Leveled top-down or Leveled straight up when the tilt is within 0.5°, or reports how far off it stopped.

Level corrects tilt only. In Follow and Tilt locked the gimbal already holds the horizon; in FPV roll follows the handle and the toast says so. With the handle upright the lens reaches about 44° down, so angle the handle forward for a top-down shot, then double-tap. Stick input cancels the move. Level and the roll direction are experimental until checked on more cameras.

EV meter

Enable EV in View Assist to show a slim white exposure line with a sun marker and a dark glow in DISP 1. The camera’s signed EV number sits above the line, with +3 and −3 at its ends. The text EV identifies its toolbar button. The meter sits just inside the picture’s left edge, slightly above center. It moves upward or shortens to clear the View Assist toolbar, including expansion. If the toolbar leaves no room, the meter returns when the toolbar closes. Tap EV again to hide it; the on/off choice is saved. The meter disappears in DISP 2 and playback.

The reading comes directly from the camera’s exposure telemetry in Auto and Manual. It is separate from the EV compensation setting in the camera controls. No image analysis, LUT conversion or additional camera polling is needed for this meter. A dash without a needle means the camera has not supplied a supported value. It never substitutes the compensation setting or an image-derived estimate.

Moving scopes

Newly enabled windowed scopes start in the center, ready for you to place them. The false-color reference key also starts centered and can be dragged. Portrait and landscape keep separate scope positions. Existing saved positions remain the landscape positions. AUDIO starts on the left at vertical center and can also be dragged. Hold AUDIO for Vertical / Horizontal bars and optional left/right dBFS readings; these affect the meter display, not camera recording.

Drag WAVE, PARADE, HISTO, VECTOR, LIGHTS, or ND directly to move it. Drag its corner grip to resize. Scopes can sit partly under the top and bottom bars. Scopes can reach closer to the bottom edge and sit underneath the entire joystick, zoom, and gimbal-controls cluster in portrait or landscape. The cluster stays above scopes. Panels can reach equally close to the left and right edges. Record, media, and settings stay protected. Panels fit the available space after rotation or resizing, including saved positions. Long-press a View Assist toolbar button for its settings.

Connection recovery now protects the first picture after replacing a connection and detects when arriving traffic cannot produce a usable picture. A dropped reference frame keeps recovery active until a new keyframe arrives. These changes have automated regressions; sustained phone-and-camera qualification is pending. If picture stops, share diagnostics with the action and time.

A Pocket 4 Pro test held 25 fps for five minutes, but later exposed slow startup and short freezes after incomplete video data. Startup now waits for the camera’s command window; known dropped-reference recovery can act sooner while keeping the last image visible. Validation of these follow-up fixes is still in progress; the earlier clean segment does not establish uninterrupted reliability.

Returning from Media now starts live view once and waits for a fresh picture. An older live-picture deadline no longer treats intentional browsing as a failed feed. If live view cannot return, bounded connection recovery takes over. Please test repeated browsing, playback and return with a connected camera; physical qualification of this follow-up is still pending.

How Swift reaches Android

Business logic stays in OpenPocketViewCore. Android follows the OpenZCine pattern, not Skip/SKIE:

1. Portable Swift core (no SwiftUI, UIKit, or Android imports).
2. OpenPocketCineAndroidFacade — session + hand-written JNI (@_cdecl).
3. Gradle :app:stageSwiftCore (just android-core) builds aarch64-unknown-linux-android29 and stages libOpenPocketCineAndroid.so. arm64-v8a only. Toolchain pin: Swift 6.3.3.
4. Kotlin core-api wraps JNI. Kotlin does not pack protocol bytes. Live handshake / first-picture / enable-once policy is cameraSoftAPDecision in the Swift facade — a handshake miss is a recoverable session error, not a crash.

Build recipes: Setup. The living JNI/I/O notes: ANDROID.md.

Operator surface

Chrome, assists, capture, Operator Setup, and media are meant to match iOS. Current zoom chips are (Pocket 4 Pro 1×/3×/6×/12×; Pocket 4 1×/2×/4×; Pocket 3 1×/2×/4× with 4K max 2×). Nano is a fixed 1× lens: no zoom chip, pinch, disc or controller zoom, and no gimbal stick or tap focus. Pocket 3’s ceiling is per-FORMAT, not one generic 4×: 1080 4×, 2.7K 3×, 2160 1:1 3×, 4K 2×, 3K 1:1 2× (survey). Zoom must not drop the live picture. FORMAT lists camcap_video_format pairs (2.7K / 4:3 / 1:1 / 9:16 when the body advertises them; aspect is the res byte). A tap stays on that pair until the body reports it. Pocket 3 normal Video also has a FORMAT fallback when the camera supplies no capability table (16:9 and 1:1; 9:16 stays body Lock Portrait unless already reported). Reported choices take priority; separate Pocket 3 Slow Motion and Low-Light fallbacks use the accepted pairs in the survey. Unknown modes have no fallback. The full Pocket 3 format/record/reconnect matrix still needs physical Android checks. COLOR follows the body: D-Log2 is Pocket 4 Pro only; Pocket 4 is D-Log; Pocket 3 is D-Log M (HLG is HDR); Nano is 8-bit / 10-bit / D-Log M; Action 6 is Normal 10-bit / D-Log M. Action 6 has no focus modes: its APERTURE tile sits where FOCUS is on Pocket, shows the live iris, and sets the strategies the camera offers. Action 6 live view is wired from the survey and not yet checked on a camera. Auto ISO ranges start at 50 on Pocket 3 / Pocket 4 and 100 on Pocket 4 Pro. View Assist ND is a small chip on the live picture (centered until placed; drag to move). Long-press to switch Stops, ND32, or ND 0.3. It meters against middle gray and suggests a screw-on ND to balance the frame. The app cannot set a filter. The gimbal stick and zoom chip sit together as a cluster in the trailing-bottom of the picture, same as iOS. A gimbal-controls button sits beside zoom (Pocket only). The gimbal button keeps its dark readout glow; the joystick uses adaptive bright/dark ink without a halo. Its trailing drawer has Mode, Speed and Ramp tabs, each with its own dial, showing Follow / Tilt locked / FPV / Direction Lock, Slow / Default / Fast, and stick ramp. The Motion Control footer opens the experimental editor for an A→B (optional C) take (set A and B, choose each leg’s duration; drag the editor directly). With C set, Smoothness rounds B and shows a dashed curve. Zero hits B exactly; higher values bypass B while preserving A/C and total duration. There is no artificial speed cap. Moves are experimental: keep the camera fixed, rehearse, and check framing before a take. Tilt is planned from where the camera points at Start. A take runs the gimbal on Fast; your Speed and Tilt locked setting comes back about a second after it stops. Tilt targets stay within −44° to +70°. A missed timed point stops the move; professional positional/timing accuracy has not been qualified. Stick throw is analog with an ease-in curve (small push crawls; full throw is fastest). Direction Lock keeps the camera pointing in the same direction while the handle rotates; choose another mode to release it. The separate joystick-hold Lock Gimbal behavior remains under investigation and is not available in the app. Ramp smooths joystick-input changes: Off is immediate, Soft eases more gradually than Medium. Releasing the stick still stops immediately. A connected game controller’s selected stick drives the same path (Left by default). Cross/A records. Circle/B recenters, or levels with Double-tap → Level. Square/X is rotate-180. Triangle/Y tracks a face in frame or cancels. L1/R1 jump zoom out/in. L2/R2 hold-to-zoom (deeper is faster). D-pad up/down ISO, left/right shutter. A toast says Gamepad connected or disconnected; unplug rests the stick. Operator Setup → Controls → Gamepad shows Connected / Not connected. Choose Gimbal joystick → Left / Right in the same Controls tab. D-pad shutter changes also update the shutter-angle readout when angle display is selected. A selected angle is retained when changing frame rate: 180° changes shutter time to 1/50 at 25 fps or 1/100 at 50 fps after the camera confirms the new format. A gimbal stop pulses only after the head moves then stalls (Haptics setting). Capture drums, the zoom disc, and duration dials pulse on coarse steps and whole-stop crossings (172° → 180°, 3×, whole seconds), not on every hundredth or half-second tick. AirPods head tracking is iPhone-only (no headphone IMU) on Android). Stick pan stays picture-relative. Stick triple-tap 180 inverts pan at the end of the rotation (like Mimo). Extra-mirror live view when that 180 lands and Selfie Flip is off; Flip on skips extra-mirror. The last picture stays for a couple of frames before that X-flip so the feed does not swap in place. Invert is the rotate-180 button at settle, not joystick 180. Reconnect-at-180 seeds TT180 from settled attitude (a 0° stub does not lock front). D-Log2 cannot zoom while rolling — the chip grays and tap/pinch toast; idle hops to D-Log on the first step off 1× and waits for that color SET before any zoom write (the chip stays at 1× until D-Log lands). Long-press View Assist options lift above the keyboard so Zebra Highlight / Midtone stay visible (Done on the number pad), matching iOS. False color Scale is CineStop / Video / IRE / Limits. CineStop paints five stops around 18% gray, the same on every camera because it reads each log curve in real stops: dark green −2, yellow-green −1, gray at 18%, light pink +1 (skin) and soft yellow +2 (upper skin limit). Red is clipped and violet is crushed; other shadows are flat dark gray and other highlights flat light gray. Video is video-level IRE stripes over grayscale. IRE is six video-level zones over grayscale (crush, near-black, 18% gray, +1 stop, near clip, clip). Read picks LOG (the raw signal, like WAVE, the default) or 709 (the camera’s Rec.709 look) for every scale. Long-press LUT for the same exposure compensation as iOS (−3…+3 at ½ stop, input-referred before the cube). Photo and Live Photo use Rec.709 for live monitoring. DJI log conversions are hidden and bypassed, including saved manual conversions; Creative and imported Custom looks remain available. Returning to Video restores the saved conversion unless you changed your LUT selection. Recorded clips keep their own color profile. 50/50 log-vs-LUT is monitor-only and must not drop the live picture (GPU split only while a cube is loaded). Next/prev with LUT on keeps the grade on the same GLES host (ExoPlayer writes an OES surface; LUT / PEAK / FALSE / ZEBRA grade in LiveFeedEffectsSession like live — TextureView is only the window). Auto on a clip reads com.dji.camera.ColorGammaSxS from the original take like iOS — not the LRF/XRF sidecar (Rec.709 even for log). Shot color is stored with the cached clip. A Proxy tag means only the 720p sidecar is on the phone. Storage Full Resolution Caching matches iOS. Pocket 3 /v2 is storage 0; the newest catalog page lists after a take even if enter-playback ACKs E0. Share/save is the original camera file — LUT bake, Bake exposure, and Convert log are iOS only. Sharing is unavailable on Android. Experimental Multiview opens from the grid button in the Your cameras header and matches the iPhone flow: choose Local Wi-Fi or this phone’s hotspot, add up to four cameras, and double-tap a live tile for full Live View. Grid fills four portrait rows or two landscape columns. Portrait keeps a vertical right toolbar below the wide main feed in Center stage, with camera details inside each feed. Landscape Center stage enlarges the main 16:9 picture, overlays its readouts at the bottom, and puts the other cameras in a scrolling right strip. Content fades softly only at edges with more to scroll. Wi-Fi sits below Exit on the left; the tools reuse the collapsible View Assist palette. Grid keeps tools in the right control column, or left for a right-side cutout. DISP and Record retain Live View positions.

New cameras start with Auto LUT on, HH:MM:SS timecode and Live View battery gauges. The … menu stays compact over the stage. Exit uses Live View Lock styling; Wi-Fi uses Settings styling and opens the shared network wizard. Camera settings opens a floating popup with a tab for each connected camera and Live View’s setting controls. Camera, recording and settings tabs have one bottom or left edge with a highlighted selection, without tab boxes. The Multiview guide describes setup, Android differences and validation limits. Platform differences, including Frame.io and MetalFX, are listed in docs/PARITY.md.

The fitted portrait feed is centered vertically, with STBY, timecode and REC SETUP in a separate row below the status area. View Assist, FIT/FILL and the joystick cluster stay above the camera values in fixed positions when switching FIT/FILL. Hold zoom for a continuous dial. The disc hub reads hundredths (1.53×); the chip still shows tenths. Dragging retains finer values without snapping to those displayed numbers or whole zoom stops. In landscape the larger zoom disc sits on the trailing screen edge and covers the controls beneath it until closed. In portrait it sits on the bottom screen edge.

The joystick remains usable while the Motion Control editor is open, so you can position the camera before saving a point. Other outside taps minimize the editor. Motion Control durations use half-second dials up to 120 seconds. Swipe left to increase duration and right to decrease it. Drag the expanded window or minimized pill directly; no hold is needed. Duration dials and sliders keep their own gestures. Dragging does not activate Start/Stop or expand. Start shows a cancellable three-second countdown before preparation and approach to A. Pause holds the move; Resume continues from the stopped position without another countdown. Stop clears the continuation. Manual control or disconnect also cancels a paused move. Long pan returns follow the reachable arc rather than wrapping through the gimbal stop. Selfie Flip does not reverse stored mechanical angles. Waypoint letters and the dashed path follow the selfie orientation and MIRROR assist visually; saved positions and programmed movements stay the same.

Use the existing zoom chip to frame a point without closing or minimizing Motion Control. Tap for the usual zoom stops, or hold to open the zoom disc. Closing the disc returns to the full editor; SET or RESET then saves the point. The camera’s zoom limits and D-Log2 recording restrictions still apply. Manual zoom takes over and cancels an active or paused motion program.

Each point also saves its zoom. When those amounts differ, Motion Control transitions between them over the leg durations; B’s zoom is reached even when Smoothness rounds the gimbal path. Loop reverses zoom too. Pause stops the zoom stream, and Resume waits for fresh, settled lens feedback before continuing. Zoom-changing programs are unavailable in D-Log2, both while recording and idle; Start shows the reason. Choose a compatible color mode yourself—the program never switches color mode. Programs without zoom changes still work in D-Log2. Saved zoom must fit the current camera FORMAT. Zoom timing and optical smoothness remain experimental.

Programmed zoom changes linearly throughout each leg, including reverse loops. For example, halfway through a 3×→6× move, the commanded zoom is 4.5×. Zoom begins with the movement and reaches the next saved amount at its endpoint. Pocket 4 Pro uses more frequent lens targets to reduce visible stepping; the camera must report that it reached A’s zoom before the timed movement begins. Very small changes are limited by the camera’s lens-position resolution. Other Pocket bodies retain their existing update cadence while their response is qualified. Optical accuracy and smoothness across every zoom range remain experimental.

Loop (off by default) moves back and forth: A→B→A→B, or A→B→C→B→A→B→C. Each reverse leg keeps its original duration and retraces the same smoothed path. The countdown, approach to A and two-second settle happen only at the initial start. The return starts without an added endpoint pause; position checks continue while it moves. Exact reversals allow the camera’s natural motor easing when fresh feedback confirms arrival and a clean return. If feedback cannot verify the endpoint, the move stops. Choose Loop before Start. Pause/Resume keeps the current direction; Stop, a motion failure or manual takeover ends the loop.

The compact editor keeps its header and Clear, Start/Stop and Pause/Resume buttons fixed. Not set and the Loop hint use bright gray text for readability over live view. While paused, Restart replaces Clear: it keeps your program and begins again from A with the usual countdown and preparation. The settings scroll above the buttons, with a subtle bottom fade when more content remains below.

Closing and reopening the editor retains A/B/C, durations, Smoothness and Loop for the current camera session. During a run, Close minimizes to the control pill so Pause and Stop stay available. Stop keeps the saved program; Clear removes the points and resets Smoothness and Loop. A new camera session starts a fresh program.

Physical Android Motion Control and Pocket 3 qualification remain pending; the recorded motion checks are on Pocket 4 Pro/iPhone. See Motion Control qualification.

Live picture: Vulkan when the device can init it; GLES fallback. Live LUT / PEAK / FALSE / ZEBRA grade the decoded 720p raster with a 3D cube (same lattice as iOS), then bilinear-fit the panel (peaking is the same 3-pass as GLES). Floating controls use blurred translucent panels with sharp labels and icons. The blur tracks the live or playback picture. Devices or sources that cannot supply the blur use solid readable panels. Page cards are solid. Assist inspectors show the selected scope or image effect without requiring that tool on the main picture. Image previews reuse the existing small source sample and effect shaders, with at most one job at 5 Hz while visible. Present path matches iOS FeedPresentPolicy (skip duplicate timestamps, keep the last frame on freeze, one live-enable write at a time, latest-wins present). Opening clips or Operator Setup over live view keeps the video GOP and the live SurfaceView; returning to the monitor must not leave a black well. Leaving live view, opening clips, or rotating must drop the Vulkan swapchain with the window — present after that is a skip, not a crash.

Saved cameras connect over Camera Wi-Fi by default. Add setup on a camera card adds Wi-Fi (a router this phone joins too) or Hotspot (this phone’s hotspot): the camera leaves its own access point for that network and the app finds it there by its Bluetooth identity. Tap a setup chip to connect over it; long-press a Wi-Fi or Hotspot chip to forget it. Choosing Camera Wi-Fi again restores the camera’s access point first. If a router keeps the phone and camera apart (client isolation, MLO on Wi-Fi 7), use Hotspot.

Wi-Fi passwords stay in Keystore, not saved-camera JSON. Pairing and live view need a physical Android phone.

TalkBack

The live-view readouts and the assist cells each speak as one labelled stop: the REC chip reads state with elapsed time, the battery rows name phone or camera and say “level unknown” rather than leaving a dash unvoiced, the timecode names itself, and an assist cell reads its tool name, state and hold gesture instead of its 9sp abbreviation.

Labelling a container needs clearAndSetSemantics. Plain semantics does not absorb children, and mergeDescendants = true does not suppress them either — the platform publishes the parent description and every child Text as separate stops, even though Compose reports the merge as having happened. Leaf nodes keep plain semantics, since a Text has nothing to absorb, and MonitorSlider keeps its progressBarRangeInfo and set action, which a clear would erase. LiveChromeSemanticsTest pins the rule against the platform accessibility tree, so a copy of the wrong pattern fails there rather than on a tester’s phone.

Verified on a physical SM-S918B / Android 16. Media, settings and pairing carry the same container leak and are a later pass.

D-Log M uses a direct 0–100 preview-signal scale for waveform, parade, histogram and zebras, without the D-Log black-point or ISO ceiling. Low/high signal warnings do not establish where the camera sensor loses detail. The false color reference (DLM ≈), CineStop stops and gray guide use an estimated Pocket 3 curve; use IRE for signal measurements, especially on other D-Log M cameras. Live-preview calibration remains pending.

ND recommendations also derive stops from that estimated curve. Treat D-Log M ND readings as estimates, not calibrated filter or sensor-limit measurements. LUT exposure compensation and Face Priority EV still use the previous D-Log approximation for D-Log M; the scope fix did not calibrate those controls. This limitation concerns exposure math, not the choice of the official D-Log M conversion cube. See the D-Log M investigation.

Saving photos and clips

Save to Photos places photos in Pictures/OpenPocketCine and videos in Movies/OpenPocketCine. If Android cannot prepare a file for sharing, the app shows an error. Camera originals remain unchanged.

Upcoming share destinations

Share shows Google Drive, Dropbox, NAS (SMB), LucidLink, Backblaze B2 and Vimeo Review as Coming soon. These destinations are previews of planned support and cannot be selected yet. Use the available destinations to share now.

On-screen joystick feel

In Controls → On-screen joystick, tune the virtual gimbal stick:

• Invert pan and Invert tilt reverse each direction independently.
• Dead zone ignores small movements near the center. The default is 8%.
• Response curve changes how movement grows with stick travel: Linear is direct, Standard keeps the current feel, and Fine gives gentler small moves.

Both inversion options default to off and the response defaults to Standard. These settings are saved and affect the on-screen joystick. The existing sensitivity setting continues to control overall speed.

The touch range extends 35% beyond the joystick’s outer radius while the ring and knob keep their existing size. Continue dragging past the ring for full input. Returning to the center during a drag respects the dead zone; lifting your finger releases the stick.

Automatic error reports

On the first launch with automatic reporting available, the app asks whether to send optional crash, error and feed-dropout reports. This also applies after an update if you have never made that choice. Enable or Not now is remembered; updates do not ask again after a decision. You can change the choice in Operator Setup → System → Automatic error reports. The prompt keeps both choices in a vertical button stack and scrolls when screen space is limited.
