I meant my question in terms of your save file. Was it created during this update or is it possible that you're playing a file you created in an older update? It's possible to play the latest version with an outdated save file which is usually the cause of most catastrophic crashes and errors.
I did some playtesting and it seems stable for me on phone.
If my theory is incorrect and you created your save file in this version, I'd be very interested to know the details of the error messages like the pages where they appear and the what the errors say.
