My GS5 is rooted, but it still does not work. The phone crashed, I had to reset the phone, and recover the data.

This app put my tab into a boot-loop death spiral. Had to reinstall firmware. Want my money back.
Exactly what I was looking for. It changes the resolution while still keeping everything natural looking. In particular, Google Maps is noticeably faster at lower resolution. One problem: the capacitive home keys no longer work, so I have to have another app running to create soft keys (eats into screen real estate)
I dropped my note 10.1, and about 3/4 of an inch of the left hand side of the screen is messed up and won't display anything. I was able to use the overscan feature of this app to move the screen over so that nothing would display on the messed up part. Not a perfect solution, but cheaper than buying a new tablet right now.
Just after changing the resolution, the device rebooted automatically and it freezed at the logo screen !! I had to do a factory reset to solve the problem. Very disappointed !! =(
Android Lollipop
The apparently does exactly as described. Frame rate on my Asus TF700t with Cyanogen 11 suffered in games from the native 1920x1200 resolution. This app allows me to drop the resolution to enjoy smooth gaming and crank it up for everyday use.
