    Default Re: Verizon LG G2 - Great Phone - Two Issues

    I found that knocking at the top, where the notification bar is, works 95% of the time. I have a D802 so that might make a difference?? oh and I am not using a case

    At the same time I also started having difficulties manually dragging down my notifications bar. It comes down just a bit then snaps back up instead of following my finger down. Now I find the only way I can successfully manually drag my notifications bar down is by slowly and carefully dragging from directly in the center of the bar. Prior to this, I could drag quickly and sloppily from anywhere on the notification bar on the first try with no problem whatsoever. Now it usually takes me a few tries.

    Anyone else experiencing screen issues like this, or have any ideas how to remedy it??? Thanks!

    It seems to me that the Verizon version of the G2 has the knocking issues. I don't see nearly as many people complaining about it (if at all) on other carrier threads. Or so i think.

    The knocking feature uses the accelerometer of the device to detect the touch. With this in mind, i tap lightly but firmly on the top or bottom sides of the screen in order to get the accelerometer going. Knock on and off works for me about 95% of the time. Using a sprint version of the device.

    I also have issue with a screen lock loop. If I try to knock-on the phone and it doesn't work, I'll try again and it doesn't work, so I push the power button. The lock screen shows up for about a second, then screen goes black. I push the power button on again and it shows for about a second and the screen goes black. Sometimes I need to do this 10-15 times or more before I can actually unlock the phone. VERY ANNOYING!! Especially when trying to pull out the phone quickly to take a picture before missing the shot. Is anyone else having this issue or should I exchange my phone?
    Have this same issue, not only with knock on but also if i use the power button. I have found the only way past the 1 second screen on time is to wipe the top of my phone on a sleeve or something. it then works fine. it seems to me like the proximity sensor is to sensitive and detects even the slightest amount of skin oil on it and after it is wiped, works fine. Love the phone but this issue is VERY frustrating. I have Verizon version, rooted but not ROM'd or skinned

    I find it works well most all of the time. First off if not noticed it is not really Knock on. Knocking has nothing to do with it as far as I can tell. Just touching the screen is all it takes, which means needs contact with you skin. If skin is excessively dry, touch screens do not respond as well. I find that two touches with finger tip is all it takes. The more contact the better, such as more of the pad of your fingertip. I have the Verizon version!
    Just a thought!

    Hi y'all

    Check out this video:



    It shows the sensor which is responsible for the knock-on feature. I discovered mine was covered by the screen protector, using an x-acto knife to cut it away has resulted in DRAMATICALLY improved knock-on for me.

    yes, the screen protector was clear. that seemed to impede the sensor enough to cause a problem bad enough for me to google it.

    son of a BE#*$YR#FH.

    Set the phone down for a moment, picked it up, knocked, nothing. knocked, nothing.

    knocked, nothing
    knocked, nothing
    knocked, nothing

    I assume a "factory reset" has no effect on this problem?

    That's not the sensor it uses for knock on. That is the proximity sensor, which is why the screen doesn't turn on when its covered.

    Knock on uses a combination of the capacitive grid and accelerometer. (You can get it to turn on if you hold your finger on the screen and shake the phone twice too)

    I figured out the problem, for some reason its can change the knock on tapping speed and pressure.
    I have a large finger, before I can knock on and off with a quick 2 taps. Now I can only knock off but not on, for some reason my 9 months old son can knock on all the time when he play with the phone, so I tried to copy him, imagine you are trying to pet an ANTS but very slow 2 tap and very lightly, anywhere on the screen it work, look like he play with my phone and got the phone to register the way he tap to turn it on, its frustrating, I couldn't figure out how to set it back to normal.

    There's no way to change the speed or pressure for knock on, and it can't change on it's own.

    Considering just exchanging the phone since I'm still under warranty but don't want the hassle if its a software issue
