Mcpe gui scaled too big for my 7 inch tablet

On my Kobo Arc 7, the GUI is scaled too big for my device and is sometimes off the screen. This is noticeable in the new world menu, and also was noticeable while using the enchanting table in 0.12.1 beta I could not see what enchantment I was getting because it was cut off by the bottom of the screen.

I have a picture from 0.11.1(the version I am currently running on my device) as an example.

I would appreciate if this could be fixed. Thanks in advance.
