Everything solved! This topic is resolved after discharging the mobile phone and then charging and turning it on ! Please help. I had 360 security antivirus installed, and they're a terrible beast. I gave the cleaning, which I subsequently canceled but it still remained frozen on the screen. IT'S A FEAR BITCH, DON'T DOWNLOAD THIS DEBILE ANTIVIRUS! I CAN'T TURN OFF THE MOBILE (I have to press the off button on the screen after a long press on the lock button) I have to wait until it runs out. Is there a way to turn this application off on your computer? Phone model: Samsung galaxy S7 edge. PLEASE RESPOND AND HELP ME!
