Easy get file explore. One of them that allows you to get into android, then data, and look for the game/app folder for the game and open it and go into files and u found your saves.
Beware some saves breaks in the new version so just try all of them to see which one works. And some does work.
The app i use is (file manager +) i used to be able to do it with the built in file management app but ever since android 8 you cant access that part of the system anymore.
