If the saves folder doesn't show up you can just try to start a new game. The game will give you a error message but you can still hit "Menu" on the bottom and save. Then exit the app and copy your backed up save files into the Android/Data/my.n.family/files/saves folder
i already copy save file 0.14 and then paste to save file 0.17 but i only can paste to download file not the Android/Data/my.n.family/files/saves folder. I try to find my.n.family file but i only found media file
The folder only appears after you installed 0.17 and you can only navigate to it if you use a file browser app I linked. Though, not every phone allows you to modify files like this. It works on my s21 ultra but it might not work on every android phone.
