my samsung galaxy s8 has a blue moving box on the lock screen and does not let me use my phone at all i cannot use the touch screen at all please help how to i get rid of this
Solved! Go to Solution.
i found the universal switch on my Galaxy Tab A... it was already off... hitting the volume up and power at same time does nothing... this tab A is useless
Just triggered this on my S9 this morning by accident, apparently just tapping, not holding, power+volume at same time up turns it on and off manually on my phone. May keep it on for now that's a better theft deterrent than anything else on the phone LOL!
This didnt work for me on my Samsung galaxy S8+ but what unlocked it in the end was my alarm going off. The alarm seems to take over the phone and unlocks it when you x the alarm. So as a future fix Ive set my alarms to go off at certain times every day just in case it happens again.
