After the new update 2.20.40.59 my handset has started behaving erratic, as if the links between the apps and system UI has crashed. The booster function from the quick settings is not responding and shows an error message that system.hi.com has stopped. When the phone switches from cover view to full screen, it stalls and hangs and I am getting a black out. Screen animation flickers as if its stuck and similar issues is being noticed in all applications. It has suddenly started overheating and even the call making and receiving has become impossible. There are no other apps other than Asus is being used by me. Please note, all apps are denied to restart except Whatsapp and still free RAM is 211MB on my handset. Need immediate help please. This is my work phone and I don't have a spare.
