📝 WalkthroughWalkthroughThe app adds motion-sensor display sleep and wake control. MainActivity manages the controller across lifecycle events. The settings screens add motion, timeout, device-admin, URL validation, and schedule summary behavior. The application version changes to ChangesMotion display and settings

Merge Risk: 🟡 Moderate · up to During inactive hours, settings changes or interaction can resume motion polling, wake the display, or arm another sleep timeout. This should be fixed before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@app/src/main/java/com/immichframe/immichframe/HardwareDisplayManager.kt`:
- Line 43: Update HardwareDisplayManager.start() so resetSleepTimer() is called
only after the motion sensor device has been successfully opened and confirmed
usable. When /dev/motion0 is unavailable or unreadable, keep the display awake
without arming the sleep timer.
In `@app/src/main/java/com/immichframe/immichframe/MainActivity.kt`:
- Line 939: Update MainActivity.onPause() to stop HardwareDisplayManager
whenever the activity pauses, regardless of isFinishing, and restart it in
MainActivity.onResume(). Preserve the existing display sleep behavior while
ensuring SettingsActivity cannot be affected by polling or
turnScreenOffForMotion().
- Around line 937-941: Update the Active Times deactivation and activation flows
in MainActivity so deactivation stops motion management before or alongside
displayManager.sleepDisplay(), and activation restarts it when the frame becomes
active. Use the existing HardwareDisplayManager motion-management start/stop
APIs and preserve the current display sleep/wake behavior.
In `@app/src/main/java/com/immichframe/immichframe/SettingsActivity.kt`:
- Line 54: Update SettingsActivity.SettingsFragment to preserve the preference
handlers for useWebView, activeTimes, authSecret, settingsLock, and
closeSettings, and invoke updateScheduleSummary() during initialization and
resume. Port the equivalent behavior from the top-level fragment before removing
that implementation.
In `@app/src/main/res/values/arrays.xml`:
- Line 4: Update the timeout label item in the arrays resource so the value 1
uses the singular text “1 Minute” instead of “1 Minutes”.

118-132: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winDo not mark the display as sleeping before the sleep request succeeds.
motion_sensor_enableddefaults totrue, andHardwareDisplayManager.sleepDisplay()setsisDisplaySleeping, cancels the timeout, and acquirescpuWakeLockbefore callingMainActivity.turnScreenOffForMotion(). Without device-admin permission,lockDeviceIfPossible()only dims the window and logs a message. The display can remain on while later timeout attempts are suppressed and the partial wake lock remains held until motion or cleanup.Make the sleep callback report success before committing this state, or disable motion standby until device-admin permission is active.

In `@app/src/main/java/com/immichframe/immichframe/HardwareDisplayManager.kt`:
- Around line 49-50: Update HardwareDisplayManager.start() so the /dev/motion0
FileInputStream probe, including its read, executes within managerScope rather
than on the UI thread. Invoke resetSleepTimer() only after the probe completes
successfully, while preserving the existing behavior for probe failures.
In `@app/src/main/java/com/immichframe/immichframe/SettingsFragment.kt`:
- Around line 94-96: Update the closeSettings preference listener in
SettingsFragment so it validates the configured server URL before calling
setResult or finish. When the URL is blank or malformed, keep the settings
screen open and display the existing validation error; only return RESULT_OK and
finish for a valid URL.
- Around line 161-164: Update the summary logic in the active schedule
preference around parseActiveSchedule and formatScheduleSummary so an empty
schedule, identified by schedule.rules.isEmpty(), produces a blank summary and
uses the existing “Per-weekday on/off times” fallback instead of “Currently
active.” Preserve the current formatted summary behavior for schedules
containing rules.
