Minecraft on tablet control gone?

I have a problem. In Minecraft on my tablet when I start a world is the controller and everything gone. What do I have to do to make sure everything is back. I've already tried uninstalling and installing.

Previously had Minecraft Pocket Edition, and there you can adjust in the settings under control or graphics, but rather under control for touch that something is there and gone. Have to try it out. It's the same as putting the controls on the right side and jumping on the left. I believe under the point Gui visible / invisible you should get it back

I'm looking Mal😊
