hey, i am getting the same thing too. it does not allow any function. i cant factory reset the phone either, since that blue box wont let me draw my pattern.

Universal switch is enabled that is the cause of the blue box. Press the power button and volume up button together to disable.

the same thing happens to me. i tried doing what you said and so many other things. I don't know what else to do . please help!!!!

I turned it off as usual, I left it charging all night. I woke up, turned it back on and these BLUE BOXES keep on appearing on the lock screen, and the screen DOESN'T WORK at all, so I can't go to settings. Only the home and volume buttons work.

Please help!!

I also tried pressing the volume and home button, the  volume and lock button,  both volume and home button, all the 4 buttons, I removed my sim card as well and rebooted it. Nothing.

Please I need your help

Guys go to your settings menu, search for universal switch, disable that ***** and it should work fine.

Disable the universal switch in the settings menu.
