Worked just fine for a long time until now and made me almost buy a new phone I used this app for a long time on my Asus Zenfone 5. About 1 month ago  mostly right after unlocking the screen and sometimes randomly  the display tilts/shifts with an absurd angle and goes grayscale and then shortly after phone freezes  makes me do a hard reset. I thought it was a phone problem because I hadn't installed a new app. But then I thought maybe it's about this app  because it happened mostly after unlocking. So i disabled it and the problem solved. Hope this gets fixed. Cheers
