I have installed some renpy games on my phone, and its OS is Android 12 and it is a Samsung Galaxy.

For all the renpy games I install from itch.io, the game crashes after short time. Is there anyone with same problems on Android 12 or Galaxy?

Haven't met this issue, self or reports from others, it might be from a setting on your device. Try to download the apk from our other pages to see if it's different.

Hello.

If you update your Ren'py to the latest version, there will no longer be any problems for Android 12 devices. 

The Ren'py's latest version (Ren'py 8) supports Python 3 now. Besides, it is better optimized for Android.
