Hello good people of xdadevelopers, I'm again in need of assistance, the problem is as follows, I noticed that on my recently bought Galaxy Tab A sm-t555 some, not all, fullscreen apps aren't shown completely, ie. part of the app missing in fullscreen, only thing I have done is rooted it with the help of this guide:

and used the:
