Screen want rotate to vertical
Allwinner A20 is a name of a processor, so I'm not sure what tablet are you using.
There is an option to block rotation, for example if you want to read an e-book while laying on your back. Go to settings and try to find an option to unlock rotation.
Also, some tablets have a hardware (physical) switch on the side that locks rotation.
