Hi Guys,

I noticed that there are more than one threads about this problem so I want to try collecting some information about it and see how many users affected by it. The purpose of this thread and poll is to take the outcome and contact LG and some Tech news websites, making LG respond to this issue ASAP.

If you not sure about having this issue, you can check it as follows (it worked for me) -

1. Open the Dialer and enter 277634#*# to enter the Service Menu.
2. Go to Device Test -> Service Menu - Manual Test -> Touch Draw Test - Manual.
3. Now touch/tap/knock/slide on the test area (all of it) until its almost full and watch for missing registration (you will touch the screen and there will be no red mark). I repeated the test several times and almost every time I had misses.

You can add the device model (H815/H815x/H812/H811/H810/LS991/VS986/US991) and more information in the comments .

I have the international H815 and this issue killing my Knock Code experience :( (Had the G3 without any issue).

Thanks :good:

Edit:

I found a video that demonstrate the issue (it's not my making, but I do have the same issue) .

The app in the video is Multitouch Test and can be download here -

Another video demonstrating the issue (G4 on the left and G3 on the right) -

Edit #2:

I sent emails to some Tech news websites, here is the first reports (thank you Android Authority and GsmArena!) -

Update [6/18]:

According to Android Police LG US knows about the problem and they're looking into it.

That service menu option doesn't work for me On the H810 AT&T variant.

I am still getting missed taps. Debating swapping phones when I get back from work travel. It's very random when it will occur.

it is happening on all lg g4s currently. im sure there will be a bug fix soon. maybe when we move up to 5.1.1

I really hope so. Maybe if they will see it's a major issue they will come out with a fix asap. For now they're (LG) saying they don't know about it and there aren't complaints from users.

LG will claim they don't know about it until we raise a storm on social media, support cases, etc. So we need to organize an effort to make things happen.

Mine's not severe, on the edges, more than anything. Most noticeable when typing "p". I know it's there so I watch for it. Other pretty solid device for me (other than no Gmail notifications, but I'm not posting about that).

I just sent mine back in today for this issue. No screen protector on mine. I have to decide if I want to go buy a replacement G4, or...something else. *dun-dun-duuuuuuunnnnnn*

I have had two G4s so far, both brand new from Tmobile. Both have this issue. I purchased one when it was released and the other one 6/8.

Is it possible that the people who are saying that this is not an issue are not seeing or noticing it, but it is still there?

Because if there is an issue with the display, and not all of the units are having it, then this is a Hardware defect, and cannot fully be fixed with software.

That's my thoughts exactly. I really like this smartphone, but this issue is a deal breaker for me. I really hope that it's just software fix. I'm not planning to return it for now for replacement as I'm pretty sure that every device is affected (if it's hardware issue, from past experience we need to wait a few weeks or months for fixed batches). I'll give it some time and see what LG doing about it...

I have used a tempered glass on my G4 from minute 1, and i notice a very, very, very slight version of this issue, where taps sometimes dont register. it is very slight however, which makes me wonder maybe LG has set the touchscreen sensitivity a tad bit too low, and it could be fixed with an update. Its definitely not a hardware issue, as so many people are affected, and these screens get tested before production with like 5000 taps per minute by testing machines (seen from youtube videos).

    I've noticed the screen won't turn on at night. That's weird right? After about 8pm the knock on doesn't work and when I use the power button the screen will flash on for a second and right back off. I figured it was because I was doing it too fast but even if I start with a single power button tap it still does it
    That's because if you cover the proximity sensor, knock on won't work. It's a feature so it won't turn on accidentally while in your pocket.

    So in the dark the proximity sensor is sensing darkness.

    I just opened up a case with LG.

    You should contact them via their live chat and reference the following case number. The more people report this, the faster we'll hear a response back. I really don't want to return this phone.
