Sometimes when I go to unlock my droid 4 using the dot connection method it doesnt work. Like I would go diagonally from one corner to the next and it would always stop and say it was wrong. Like i was picking up my finger which im not. Its very annoying having to log into my gmail just to get into my phone. I really like the dot connect but its just acting up for me. Is it because of my screen protector? I have one on. .
