Swipe pattern for broken screens? I had a swipe pattern lock set on my LG G3 phone. It felt down and the glass broke, so I cant use the touch screen any more. 

Is there any way to connect my phone to a kind of a screen emulator, so that I can enter the pattern on a emulator and unlock my phone?
I'm afraid not, you now have to enter your boot menu and wipe all data. This will remove the lock.
