How can I unlock a pattern lock if my screen is defunct?
YES That worked for me!!!

I've broken my screen, and after removing the SIM to another phone, the avast alarm starts louder every time I turn on.


Connect USB
Open KIES
Let the KIES waiting the screen unlock

Ensure choose the correct device, unlock the screen.
Done!!!!!
