What would happen to my worlds if I Uninstall minecraft on my tablet and re-download it on...

Hi there Arson, my name is Gerardo, and I'm an Xbox player. I'll be happy to assist you with any questions or concerns you may have.

I'm not completely sure, but it seems that on mobile devices, worlds are deleted if you reinstall the game, so you might need to back up your worlds to avoid losing them.

I recommend contacting the dedicated Minecraft support team directly through the following link to confirm whether the worlds are deleted upon reinstalling the game on that device and to find out how to back them up if possible:

I appreciate your understanding and I wish you good luck!

Kind regards,
Gerardo.

So if I were to uninstall, the re-install Minecraft, there would be no guarantee that my worlds would be saved?

it looks like you're trying to get an Xbox game on a tablet. you would have to get the new minecraft, titled "Minecraft" on the xbox store. you would need an xbox one or better. your worlds should sync.

in my previous reply i thought you wanted to transfer worlds from the xbox to the tablet

I tried this and the Minecraft re download part worked but I still can’t download my world.

My name is Zaven and im very Disappointed with Minecraft. I’ve create a Minecraft world 5 months ago, and started it in July and just yesterday December 12th, 2019 I turned on my Xbox and played Minecraft just to come to a world list full of my
other world except my world that myself and my cousins have been working for 5th months... I’m very positive that i did not delete the world because it have never messed with the game setting nor have turned the world to creative, All i want is to is what
happened to my world????

Ive tried everything restart my xbox, “Clear local saved games” uninstall and then reinstall Minecraft I don’t know what to do! And i really want an answer please help Myself and friends and also my cousins have put our time and effort in this world and we
are all bummed. Like i said i dont no exactly what happened to the world I just would like an answer if I can get it back or not and then that’s when I’ll except that my world is gone...

If it was not synced to the cloud when you cleared saves and uninstalled marked it impossible to get back. Are you sure it was the bedrock version or that maybe it was not your world but your cousins ?
