Hi there, UnderBow!
I think that when you uninstall games on Android , all the save files are removed as well. I'm not 100% sure, though.
If they are still on your phone somewhere they're probably here: SD:/Android/data/com.{gamename}.program/files/saves/
Through Discord, I could give you a save file if you'd like, but I'm not an Android expert so I'm sort of useless when it comes to troubleshooting.
