App restarts and shows lock screen when zooming images in third-party apps (also occurs on screen rotation)

[pratikwayal01]

I am experiencing an issue with AppLock when using third-party apps such as Google Photos or Instagram.

When viewing photos inside these apps, everything works normally at first. However, when I zoom in on an image, AppLock suddenly shows the login screen. After unlocking, the app restarts and returns to the home screen instead of resuming where I left off.

The same problem also occurs during screen rotation (portrait ↔ landscape). Rotating the device triggers AppLock again and resets the app state.

Steps to Reproduce

1. Install AppLock from F-Droid
2. Enable AppLock for Google Photos, Instagram, or similar apps
3. Open a locked app
4. Open any image
5. Zoom into the image OR rotate the device
6. AppLock appears and forces re-authentication
7. After unlocking, the app restarts from the home screen

Expected Behavior

• Zooming images or rotating the screen should not trigger AppLock
• After unlocking, the app should return to the same screen/state
• AppLock should only activate when switching apps or leaving the app

Actual Behavior

• AppLock triggers during image zoom or screen rotation
• The locked app restarts instead of resuming
• User is taken back to the home screen after unlocking

Impact

• Makes photo viewing in third-party apps frustrating
• Breaks expected Android behavior for gestures and rotation
• Poor user experience in image-heavy apps

Possible Cause (Suggestion)

This may be related to:

• Activity recreation during configuration changes (screen rotation)
• AppLock intercepting temporary activity transitions (e.g., image viewer or zoom activities)
• Improper handling of Android lifecycle events

Environment

• App version: Latest (Version 2)
• Installation source: F-Droid
• Android version: Android 15
• Device: Samsung Galaxy S25 Plus

Additional Notes

This issue happens consistently and significantly affects usability. Proper handling of screen rotation and temporary activity changes would greatly improve the experience.
