Is there any way to move my save file from one android device to another?
I have had to do this before, easiest way is to use the phones file system app (just called files on samsung phones) once you have found the folder containing the files you wish to move, send them via whatsapp to a secondary number.
Once you have migrated your SIM card to your new phone, you can send the file back to yourself via WhatsApp.
Alternatively when migrating from android to android you can just use the file migration system and select <advanced> to highlight individual files you want moved.
just don't send the unpacked. Apk, download a fresh install file then paste the save file in the appropriate place
