Do you only have problems entering gallery mode?
You can try the following steps.
-Turn off Full Screen Mode in Options.
-Update your Android version.
-Close other applications.
-Reinstall the game and ensure no files are damaged or missing (you may want to back up the archive Android/data/com.Jashinn4264.Syahatasbadday/files).
If the problem is not solved, please provide me with your phone model number. ヾ(•ω•`)o
