Does anyone have this issue with their LG G2 with pattern lock always popping up? When I use the traditional pin code lock, I have it set to 5 minutes. I like the pattern lock as it is easier to swipe to unlock the phone. But I noticed when I have this feature, as opposed to the pin code lock, it randomly pops up, almost like a glitch. It happens randomly, when I am going through my contacts. Is this a known bug? Brand new phone.
