I found the solution!
Requires root and android 4.3+!!!
This app can change your resolution and also add virtual buttons.
You will need to change the height about 1.5cm smaller.(can't see it very good on your picture so check it before applying!) If you have any problems with the app, check the app's description or post a comment below.
Hope my answer helps you!
