Issues with the LG G4 touchscreen prevent quick taps and touches from registering on the screen

Issues with the LG G4 touchscreen prevent quick taps and touches from registering on the screen
An entire thread at XDA is dedicated to a problem with the LG G4 touchscreen, which apparently is lagging and is not registering quick taps and swipes. This prevents the phone from correctly utilizing the Knock On and Knock Code features. With Knock On, you tap the screen twice to wake up the phone. Tap twice again, and the phone goes back to sleep. With Knock Code, the user creates a series of two to eight taps that lock and unlock the phone.

XDA has surveyed 194 LG G4 users and 40.21% of those asked say that they are having no issue at all with the touchscreen on the handset. That means that almost 60% of those surveyed are having an issue with the display. There is a way to check how responsive the screen is on your LG G4. Open the dialer and type in 277634#*# to open the service menu. Go to Device Test -> Service MenuManual Test -> Touch Draw TestManual. Tap, touch, knock and slide on the screen and a red mark should appear on the spots where the screen was touched. With this test, you can see how bad the problem is on your LG G4.

Are you experiencing something similar with your LG G4? Keep your fingers crossed, praying that the issue is merely a software problem that can be fixed with a simple update. Better hope that this is not a hardware problem because if it is, LG will have to start exchanging faulty units for ones that work.

This is what happens when you buy cheap crap, 2nd year lg as made a phone with big problems

30. singhkaran9830 unregistered

You can't definitely say its cheap product,it might a software issue.Maybe touch sensitivity was too low which can be increased.And not everyone is facing the issue so probably a software issue or manufacturing defect only in those units.

It's an lg phone. Issues are unsurprising.

LG pulled an HTC. My M7 capacitive buttons didn't work properly for like a month or more until they finally released an update.

oh i'm a bit interested on G4, but this issue might be a biggest letdown for me.

LG can't seem to get the basics right, not that surprised, It's a shame for LG G4 owners but hopefully it's a software issue and not a hardware problem.

Not a surprise, the Apple Iphone 6 series is a Bender, the Samsung S6 has poor battery life, n the LG G4 touch issue. TJERE is no flawless phone.

IMO the first LG optimus g pro is still the best lg to date. Im still using mine after over 2 years with no issues at all. Perfect 1080p screen with an awesome home button LED with capacitive touch buttons and a great camera. Why lg strayed from that formula and developed this subpar g series who knows.. Ive tried g2, g3, and g4 and they all had too many issues. They need to release an optimus g pro 3 to compete with Note series.

This is reduculus ... Thats not an issue you test this app ..lG G4 is one of the best capacitive touch screan lg made it like that so that you can. Controlling the phone when its raining .. That what other phone cant do .. This is not a probleme this is step up ..

Yep, one of a couple reasons I just sent back my G4. Touches wouldn't register here and there, not a huge issue at first but it quickly became annoying. Another reason is, as good as the display might be when facing it straight on, it still washes out like crazy when viewed in oblique angles. Not quite as bad as the G3 did, but still for a flagship phone I don't want to see a panel that degrades like a entry level one in some angles. Even my Moto E 2015 doesn't washes out as much.

Also it will start to lag after 2 or 3 months, my s6 edge is as fast as when I 1st got it on the 10th off April due to the ufs 2.0, no joke ( it's faster as bugs have been removed like the flipbord home screen move back home page flick

Agree, my experience with LG phones is that they end up lagging quite early. Call me crazy but I had the GS6 before the G4, and I gave it back because of the screen which gets a blueish/greenish tint on whites when you tilt it, and I'm very picky about screens, and also I'm not a fan of physical home buttons, I always get the sense that it's going to deteriorate over time and that it's not as fast as on-screen buttons. Other than these 2 annoyances, the S6 is a great phone. I want a flagship phone and I'm left with not much choice. I might go with the M9. Yes, the M9 lol. It seems like the last update fixes a lot of stuff regarding camera and battery life.

S6 has ram issues and bad gaming performance G4 adeeno 412 is better then Samsung GPu G4 is the perfect phone right now and thats not an issues my G4 work fine and i love it .. LG say thats the panel using on the g4 can resist under water you can control the phone when its raining

There's no question that it's a really good phone but the fact is that my screen was not always responsive and it looks like I'm not the only one. It seems like LG is struggling with the little things. For instance, I had the G3 and on both the G3 and G4, animations suddenly disappeared with no reason. I ended up having to enable developper options and put the animations back manually. These are little things but they get annoying over time and it gives the impression that LG phones are not polished.
