Using the app will cause image retention (ghosting/burn in) on your cellphone display panel. You will see the "For You", home button, plus sign... It also happens a lot faster than other apps. It's just a horribly designed interface. There are apps that claim to remove retention and burn in. Apps that use overlays to try and fix the issue. Those apps also yield mixed results. YOU WILL HAVE TO REPLACE THE DISPLAY PANEL ON YOUR PHONE!
