Thanks for the reply. But I already know those who succeeded had root access to android data. Without it, I can't do a full backup, so I'm kind of stuck. There's no other apps that can bypass it unless you have root or system access.
I was hoping you could do what mobile Terraria did, where they moved the save file locations to a non-system folder, if possible, please. I think that might be my only hope, or else I'll have to restart all of it again...
By the way, unrelated to the save file problem. I noticed the game had black bars on top and on bottom, making the game screen smaller. Do you think you can do something to it too? I know it's not a functional problem, but that would help my eyes, so I'll be grateful. Thanks in advance.
