Game fall back after swit a save from application to outside storage

Dear developers of Minecraft,

I am a player of Minecraft for Android and for win10 and I am writing to you to report a bug so that you can fix it up.

I have bought a Minecraft on my Sharp shv39 and played the game on it. But I found that when I tried to save the game from the application to the outside storage it will quit at once.I have tried again and again but it doesn't still work. I wonder if you can fix this bug up so that I can export my game save out without root.

Thanks a lot.You can always contact me through this email address if you have any questions. I'm looking forward to your reply.

Good luck.

 

Yours

Eric Lee.
