There's an option to save on a file, wasn't there? Do that and it'll save your entire save library. Then load that file on your other device.
Can you explain more and more details I will be grateful to you
Where can I find those files? Obb or data I think?
Technically whenever you open load game menu there's Buttons on lower area (from file and to file) to turn your save into savable file press to file and if you want to Load the save from your phone press From file and find it, That's all
