I have Minecraft Pocket Edition (PE) 1.8.1. Its installed on a Sumsung Galaxy S4 Tab. What can I do to back up worlds and restore? I like to do this before installing mods or add-ons or doing and upgrade.
This is a forum for Minecraft Pi Edition, not PE, so you may want to find the correct forum.
Have you tried Google?
