Lg g4 tap to lock an unlock

[AC Question]

When i double tap to lock it works. But doesnt work to unlock. 5 mo old. Sprint did a reset...now what?

do you have any sort of lock security feature enabled on the screen and are you running any sort of custom launcher / 3rd party lock screen? if Sprint did a reset on your phone (why?) then maybe you should take it back to them so they can have a look.
