[Q] Portion of Touchscreen not responding - G2 Q&A, Help & Troubleshooting

Has anyone had an issue like this? My LG G2 on Sprint has lost touch sensitivity on a bar for about... 12% of the screen? It starts about a fifth of the way down the screen. Knock on no longer works,and I can't hit certain buttons (like install in the play store) in default orientation. I'm not sure why this happened, as I haven't dropped it or gotten it wet. I've turned it off and on several times since it started and I am going to try doing a hard reset next. I first noticed that my knock on wasn't working, then I went to play a little bit of bejeweled and realized I couldn't touch a certain row. I am very sad right now

Just a little bump, looking for some help.

yep same thing happened to me on my first G2. VS980. Now i'm on my second. just send it in for a warranty repair man.

According to vzw it's a common issue. On my 3rd G2 now, both previous devices had the same issue. Infurating.

Alright, thanks. Hopefully sprint will be of some help to me.... I doubt it though.

Same problem I had on my Verizon version. Send it in for warranty.

I have the same problem with mine. Should I contact LG directly or go talk to someone at the Verizon store?

Contact lg directly for repair under warranty so that you won't be sent a refurb device.

Yep, Sprint is no help, so I need to send it to LG. Now I just need to figure out what to do for a phone in the mean time.

Sprint sucks!! I have had my g2 replaced 3 times since January!! Or is it LG?? SO ANNOYED

I have same experience with my Sprint G2 LS980.
On receiving my G2 i noticed i had issues pulling the notification shade but i realised the problem clearly with first time play store setup. "install/update" button was not working as it was in that unresponsive area. I had not dropped it or anything and handset was received defective, but many people have reported sudden appearance of issue after some usage too. Cloudy also has mentioned it.
This does not seem to be a rare problem and has been reported by many. Got the set replaced from my ebay vender who was kind enough to change it.
Try to get replacement from your vendor. Else get the digitizer and main board changed in aftermarket shops. screen replacement only does not seem to be permanent fix for this.
Cheers

hero touch screen unresponsive

hey guys, i have started experiencing weird issue with my hero since last week (bought it last december). the sense ui behaves weirdly and when moving across scenes its getting unpredictable with the touch response. if i go back to my home screen, it still feels am trying to oscillate between multiple screens.
on top of it, using smart dial has become a pain with its unpredictable behavior.
Though factory reset would help but now the touch is unresponsive that i couldnt sign in to my google account as keypad doesnt recognise my entry.
any one experiencing this issue? on top of not getting androind 2.1 this has been a real bad week.
any help is much appreciated.
cheers.
Go into the recovery menu and do whatever thar? I'm not sure this will help as capacitive screens seem quite failsafe, contact orange/insurance

Yeah I have the same problem, and factory reset doesn't help...
I'm gonna go to the Sprint store, and you should contact your carrier support. This problem is caused by device overheating, which damages the inner LCD screen. This screen makes the outer glass or reinforced plastic screen responsive.
It's free to fix with insurance, and $100 without. Of course, there is the chance that your carrier could be nice to you and replace it for free...
similar problems on my end too! gonna go to sprint soon
I have had this problem with my HTC hero on T-Mobile here in the UK earlier this year. Took the phone back to T-Mobile and they sent it off to HTC. After almost a month without my HTC I started to get annoyed. Eventually I got the phone back and was told that the main circuit board had been replaced.
The phone's been ok for about three months and now it's started again but appears that it's only the bottom part of the screen thats affected, where the three touch screen buttons are.
The phones going back again today but interestingly I worked out that it only seems to do it when the phone has been in my pocket and has got warm. The effect is that I can't press the touchscreen 'Phone' button or any of the buttons at either side of it but if i press any of the icons above them the phone button will be activated. (wierd!).
Now here's the thing, if I leave the phone on a flat surface in a cool air flow for a few minutes then everything goes back to normal. Which leads me to think that the problem is temperature related.
Regards
Quite strange, mine has started doing that too. Only when its warm though... Lol.
HTC has confermed to me that many Hero's have a bad touchscreen.
They will repair free under waranty.

[Q] The touch screen goes crazy and lag

I have a G2 LG D805.
I notice that sometimes the notification bar operated without being tagged, and after a while the screen does not react; I have to fix that lock and unlock the screen.
I upgraded to Kitkat and ROM changed him, to no avail.
I can not be so, is there any solution to this? Thank you

I don't want to sound pessimist, but I think that what you are seeing is a common LG G2 touchscreen defect.
Some of the problems reported are:
1. Ghost touches
2. Over-sensitive touchscreens
3. Some specific area of the touchscreen does not respond to touch. Most commonly close to the top of the screen.
Unfortunately LG has not addressed these issues at all and there seems to be no permanent fix to any of those symptoms.
Some people have managed to fix some of the above with certain ROM/Kernel combinations, some have gone great lengths to even replace the whole screen/digitizer assembly only to find the problem returning after a few weeks or months.
I just read on Reddit that some user is on his 7th LG G2, so it's not just a "bad batch" with problems but a very common one.
I am experiencing the sudden touchscreen malfunction on the top part of the screen.
Good luck!
Thank you
i have gone through 2 digitizer assemblys and the problem still occurs.
Mine developed the bad touch area and phantom touches. The jerk at the local Verizon store told me he talked with "an expert" and that I had dropped my phone, after he told me it was a known problem. Told me to file a claim on insurance, which they turned down. Called Verizon's toll free number and lady was upset on how I had been treated and promptly overnighted me a replacement.
did you find any solution?
same problem with my lg g2 d802

[Q] TV-LIKE(snowy) screen , any help with that? It must be a design defect

Hi all dear members. Since the first day i bought this phone i've been seeing lots of screen issues about it but i never thought i would have one. It's proved me wrong.
So here's my problem, my device has developed halo all around it when the bg color gets grey. Most of the time , it's not obvious. I can live with that. Recently, my screen starts to show me some tv-like stripes every now and then, it doesn't last long. after one second or two, it disappera and then it'll show from time to time.
I'm afraid it's just the start. It's similar to most of the issue ppl claim as screen flikering or screen jittering or shaking screen, it's a bit different though.
Has anyone encountered the same issue. More importantly, has anyone found any solutions yet? I searched google and failed to find answers. And i looked into it on Baidu,a chinese search engine, where i found some answers that claims it's not the screen issue ,instead , it's just the ribbon cable is lose. And anyone who replace a new screen for that is stupid.I'm just not sure about this.
My phone was bought on the internet and shipped to China, thus, I don't have warranty to rely on. And my phone is only 10 months old. I never dropped it and i have kept it well.(LG logo on the rear back still falls off), I just don't get why LG made this so vulnerable.
Even though i have ordered the nexus 6, my g2 running CM12 is still crazily fast and I don't want to give up on it. I'm so happy about my d802 except for all issues about the screen.
Any help would be aprreciated. Thanks again. Hi all dear members. Since the first day i bought this phone i've been seeing lots of screen issues about it but i never thought i would have one. It's proved me wrong.

Hi, I also have a problem with the screen on my lg g2, appeared to me that the white line disappears and comes back, when I do print screen and transfer the image on the computer that line is not visible, and that line is not always the same intenziteta.Try to do print screen and set an image or we send the mail to compare the problem
i'm so pissed about the screen, yes, my gnex bought 3 years ago looks yellow and ****ty. but other than that, totally fine, but for g2, ive read so many complaints about it. Guess no one has figured it out. Maybe I will open my phone and try to figure out when the screen completely goes crazy. During I type, it has happed for 4 times . so very annoying.

I think you should try to put in some rom, I hope it's a software problem, I found the solution for my phone cloudy g3:good:
i flash different cm12 nightlies. i don't think its a software related issue. I'm not the only one with this issue. Yesterday I opened this phone ,well with my fingernails. And coz I didn't have the right screwdriver, I wasn't able to open that black cover at the button down bellow the battery, but I cleared the places around the USB port and there's a black tape glued near the camera , I pressed it and I put the phone together and guess what, the problem was gone for one day, and I will continue to keep an eye on it.

Phone went nuts! Only long-pressing touches on my G2!

For a few weeks my G2 was showing some very weird touchscreen issues, like ghost touches and dead spots where touching wouldn't do any good. Although the former problem seems to have been gone, the latter looks kinda permanent. But yesterday another problem showed up: my cellphone will only recognize touches if I long-press the screen for like three seconds. Eventually if I'm typing some password the touchscreen will work as well as ever but only for a short time, then I'll have to press the screen for three seconds for every touch I want to be registered by the device. Anyone has had this before or heard about this? Is there a fix? I looked at lots of threads before and none of them seemed to sympathize with my issues.
It looks hardware failure. My advise would be try and go into service menu and then settings and update touch firmware. You never know it might work

That was my first bet. It didn't help much.
I had the same problem and it comes back with random conditions. I had the digitizer replaced (not the complete LCD panel) which had my problem fixed for almost six seven months until the problem showed up again but the dead zone moved Much lower than before. I have not gone for LCD replacement because i don't know if it will fix my problem. There are numerous threads here. Go try them Maybe they will work out for you.

advice on lg v20 screen burn in

hello, i have a LG V20 (H910) and i owned it for around a couple of months before this happened. my phone randomly over heated, rebooted itself and then the screen turned colours; eventually, the screen lost it's functionality. all the buttons and such work, and registers very few taps; however, a while back, i went to a shop to have it inspected. the shopkeeper said it needed a screen and i had to pay upfront + useless information; albeit, with no proper 'inspection'. i think it's screen retention. it ghosts very badly, and gets a bit hot to the touch. at this point, the screen is completely useless.
can i get any recommendations on how to fix this, or replacement ideas?
and an explanation would be appreciated as well,
thank you

Are you using a kennel with kcal support? Also have you considered changing the thermal paste? Couple of posts here about it.
It sounds like your issue is not the same as I have seen, but both V10 and the V20 have this curious "faux screen burn in/image retention" issue. I say "faux" because the particular issue I have seen can't be burn in. Burn in is permanent, it's literally an image burned into the effected pixels. But the issue with LG's is that there is an "after-image", often of icons on the notification bar, and it actually will change, fade away, or just be there for a while only to just suddenly disappear. I really don't know what could cause this, it happens often on my current V20, but also randomly and with no apparent reason or cause.
FYI some people have said this worked for them to fix the above-mentioned issue, but it requires root. I have not personally tried it. https://forum.xda-developers.com/v20/how-to/lg-v20-screen-burn-fixed-t3661631
