    Default LG G2 screen lock loop

    Is anyone else having issues with the screen lock turning off before allowing you to unlock the phone?

    What's happening: I will attempt to wake the phone either by knock-on or power button. The lock screen will appear for about a second then turn off. Sometimes I need to do this 10-15 times before it allows me to unlock the phone. EXTREMELY FRUSTRATING!! Especially when trying to pull the phone out to take a pic and you miss it because of the damn phone lock loop.

    What I've tried: I tried resetting the phone to factory settings with the same results. I've tried to turn off the screen lock pattern and just use the slide feature and it does the same thing.

    PLEASE HELP ASAP! I have 1 week left to return/exchange the phone at Best Buy so I'd like to get it resolved or if I need to get a new phone, so be it.

    I have noticed the phone does that when its charging. Maybe somehow it thinks its charging? Dirty mini usb contacts?

    I've noticed a similar problem, but it only shuts off when I have it in a Ziploc bag. I put phones in bags when I go for bike rides to protect from sweat, rain, etc. I did a little troubleshooting and it seems that the proximity sensor must see the baggie then shut the phone down. I'm guessing this is a "feature" to turn your phone off if it is accidentally awoken in your pocket. If I block the sensor and wake up the phone it shuts right back down.

    So I think I've found why my phone is shutting down immediately in the baggie, but I can't figure out how to turn off this function! Anyone have any ideas??

    cwhyman1, in your case perhaps you have a case or something that is covering the proximity sensor? Or did you already figure out the problem?

    This exact thing happens to me when I have the upper left of the phone covered.
    Right where the camera is.

    I ended up exchanging the phone for a new G2. I haven't had the problem with the new phone.

    My 1-day old G2 was also doing this. It was IMPOSSIBLE to keep the screen lock from instantly re-activating.

    Interestingly it seemed to very rarely to have this behavior in Flourescent lit rooms. It also seemed like the black hole in-front of the forward facing camera wasn't perfectly centered.

    I exchanged it, premature screen lock is now gone, and center-tap un-lock now works much better. If you (other readers) are experiencing this, most likely your forward-facing sensors are not properly calibrated. Get it exchanged.

    EDIT: Add missing conjunction.

    My screen protector was ultimately the cause of this issue for me. I pulled it up and trimmed it to expose the proximity sensor.
    Install a proximity sensor app to see what is going on.
    When you uncover the proximity sensor it should immediately go 5.00 cm. With my screen protector on, it would take anywhere from 2-30seconds for the proximity sensor to realize that it wasn't covered.

    I was going to reply that it's the protective cover sensors acting up.

    Sporadically have this same issue. It's not frequent enough for me to want to swap the phone. I'm outside my 14 day window anyway so I'll just keep it as is.

    Last I checked, that's what the tentative date was for a fix. I noticed that if you hold the phone upright and don't tilt the screen down to find the buttons on the back, it doesn't do it. (Atleast it's stopped doing it for now while I'm trying that fix out)

    This happens to me time to time, just clean the, sensor with a soft fabric
    Like the eye glass cloths. .
    It'll. Happen later, you just gotta clean it, but if the sensor isn't aligned right, just get a new one

    The G2 has a insanely sensitive screen, ive noticed my phone only does it when the screen is smudgy or has some dirt on it, once i clean it off the problem goes away, there was probably something on your screen (scratch or smudge)
