Hello all! I have a Sprint non-rooted LG G2 and I just got it a few days ago (this is my second G2). I have noticed that when I go to turn the phone on (wake) that there is sometimes a delay (no more than 2 seconds) before the screen turns on. I experience this once or twice every 15 times I press the power button. This also happens no matter how long the phone has been asleep- 5 seconds, a couple of hours, it doesn't matter. I didn't have this issue with the other LG G2. Is this something that I should be concerned with? I never experience the delay when I use the knock-on feature, only when I press the power button. Thanks so much!
