how to change version 0.14 to version 0.17 in mobile
Finish 0.14 on your phone, then, depending on your android version you have to do the following:
Android 11: Navigate to Android/Data/my.n.family/files/saves folder, copy all files into a different folder and delete the app. Then install 0.17, start it once and close the app. Then navigate back into the folder and put the save files in there again
Android 10 or below: You can just delete 0.14 ( if you saved at the end like the game told you to ) and then install 0.17 and continue with that savegame.
No, you need a file browser app, not the integrated filebrowser. I recommend this one: https://play.google.com/store/apps/details?id=com.marc.files
