M1510569965107, Dec 7, 2018 : I kept on shutting down and rebooting my Oneplus 6t but I still cannot control my phone. There are constantly green squares surrounding the area of the screen where I touches ( see images) and there are constantly Chinese audio speaking as I control the phone. I cant even stroll my notifcation bar to go to the settings to check iut what had happened. My phone is kind of like being hacked by sby. Please help... this is driving me crazy!!!
