For some reason with the Android version, dunno about the other versions, using the gallery not only crashes the game, but locks the gallery again so you have to to go back and unlock it. It also switches the game back to the default language which is Japanese.

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
