H918 Screen glitching/ flickering - LG V20 Questions & Answers

Wondering if anyone else has had an issue with their screen suddenly start glitching and flickering and being unresponsive. I just went and ordered a replacement v20 through t mobile due to the issue. I was rooted running stock Rom and kernel at the time but I don't see why that would cause that.

Sounds like possibly a faulty digitizer... But could be wrong.. Doubt it was root, more people would have been posting.

Possibly that or the display itself who knows. It was just really odd and i hope it doesn't happen again to me or anyone else. It"s kinda funny the t-mobile rep i talked to at the store tried blaming it on being rooted.

[Q] Misbehaving N1

I got my AMOLED N1 back in Feb 2010.
Unlocked bootloader, rooted 2.2.1.
The problem which existed from day one but showing much more often these days, is that after running an app (e.g. Market) the touch screen misbehave. It either does not register the touch, or maps the touch about an inch lower from where it should be. The phone has plenty of free memory (internal).
The problem is more prominent since the 2.2.1 update (but I am not sure it's related).
Does anybody else experiencing this?
TIA
Most people!
There is no solution other than the temporary fix of turning the screen off and then on again.

Yes.
I'm getting really frustrated with the N1 due to the ****ty touch screen.
I had a play with my brother's Nexus S.... SO much nicer and smoother. The touchscreen on the N1 is abysmal and shocking!
I've also noticed "freezes" in the sense that the display won't come up - only the touch screen buttons light up and then slowly fade off.... only way to recover is to pull out the battery. Really annoying.

Thanks DirkGently1, itay1,
Is there anything that can be done to fix this? e.g. replace a part (whether under warranty or not)?
It is actually becoming hard to even use the N1 as a phone or for text..

There's always the option of selling the phone while it's still worth something and buying something else!

oh well...
It sounds like yours is worse than the normal problem. My screen will only mess up once every few days, some people have gone months, some a few times a day.
But if your phone is unusable just get it replaced under warranty.

My first experience using Android was turning on my Nexus One and encountering this issue the very first time i had to use the screen! The device i have has had this problem in varying degrees since i got it. Very bad to start with, not so frequent after i sent it back for repair.
Take a look at the poll from my own thread about the issue...
http://forum.xda-developers.com/showthread.php?t=878477
Pretty commonplace problem, which along with the power buttons failing detracts from an otherwise great phone.
Blame HTC, I had this issue on my first N1 earlier last year. I would turn the screen off then turn it back on.

I find it behaves better when the screen is clean. Perhaps finger grease can confuse it... it might be *that* sensitive.
I flashed the frg83d update this morning and I've gone all day without the crazy screen thing and I'm loving it lol!
*knock on wood *
Hope it stays that way!
@DirkGently1:
I've added my vote
@itay1:
I was just about to write the same thing. It is much better after I've cleaned it (which I didn't for a while)
I am not using any screen cover. I never did. But maybe there is a cover that helps. Those of you who never suffered from this issue, do you use a screen cover/protector? which one?
Also, maybe the issue is intensified by how dry (or not) our fingers are compared to others..
@dusty-:
Do you mean frg83g? frg83d did not help my case. sorry..
Yes I meant frg83g lol

Nasty screen bleed

Hello my friends,
for some couple of weeks I've noticed some nasty screen bleed as seen in attached pics, bleed enhanced mostly when WiFi is used, and decreased but still there when WiFi is off...
D802 SEA model + 4.4.2 STOCK.
Any ideas? Should this be because a defect screen batch or something else?
Thanks in advance.
That isn't what screen bleed is.
However, you have a display hardware issue and need to return the phone under warranty.

Well, yeah, isn't the exact definition :-| but the results are kind of the same...
it's a screen bleed like or screen burn, but ... it's possible to be because of WiFi overheating?
I'll return it to my seller hopefully for a hardware replacement.. I'll let you know.
Anyone else experiencing the same behaviour?
Tks.
No. This is a hardware issue, and you should get a new one. Especially of you haven't rooted it or flashed any roms yet!

You may need to flash a kernel that matches your display. G2 is made with 2 different panels and if your kernel is using one and not the other you will have an issue like this. Did this start happening after using autorec by any chance?

Try resetting to factory defaults. If the issue persists, return it for warranty service.

Well your situation sucks then ;p do you see the LG boot logo or even that not? can you try to maybe flash KDZ after you have backed up all your data but i guess you need to do that blindly or you need to have LG OSP(on screen phone) idk or you are able to blindly enable it but maybe you should see like an LG G2 review whereyou can see the settings app so you can enable the things you need to get On screen phone working.
guys i still have this problem, any one there who can help me? you guys thin think this is software related ? i sure hope so :| can i try a custom rom ? i never installed a rom before :/
@Demitha I am not sure since it can be both hardware and software problems which can cause a blackscreen.

screen connection problem
hi buddy,
I have the same problem and i think it's a connection issue.
In my case the screen sometimes goes off or changes color intensity or inverse color.
the solution is to knock on the lower side of the screen and it turn on correctly.
firstable it happends rarely but with the time it's comming very annoying.
now just holding the phone hardly or connecting the headphones or charger the screen goes ****ing itself and i have to knock severly or push it to resuscitate it.
i'm thinking in opening the device and look the connections to solve it.
I had similar issue with my previous phone. But I had something like few points where I had to press to get backlight working again, eventually it stopped functioning at all.
As I found out, screen cable was damaged and I figured out that it had been due to dropping the phone or other kind of mechanical damage.
In case if you don't have a warranty or something, my suggestion is to open back-cover and check if you can find anything that is wrong with screen cables. But in worst case scenario it is due to faulty motherboard.
This happened to me few weeks ago, definntely hardware related.
I tried to open my phone and check stuff around, but I'm no expert, and couldn't find anything weird.
So I ended buying a new G2....

Dead Screen Touch

My LG G2 (d802) started having dead screen touch in some small portion of the screen. I just installed Cloudy G3 Rom about a week ago and the problem started showing 4 days after installing the rom. Not sure if there is any connection.
Today i flashed Paranoid Android and i still see the dead touch screen problem is there.
Is it hardware issue? Or still is there any way to find out if its a software issue?
Any help appreciated

can't live without my phone lmao so I havn't done anything yet :/ probably just going to wait till the contract is over with verizon :/
Yesterday I noticed the same problem with mine (D801)...
I think I read somewhere it's pretty common hardware defect.
I'm out of warranty so I'll have to live with it.

Exactly what part needs to be replaced? The display or just the touch sensor?
My one started going crazy. Now it detects press automatically as soon as I turn on the screen. Had to turn off knock-on feature or it would keep turning off and then back on the display again and again.

I was ignoring all the posts about this issue when I browsed the forums, I thought I was safe since my G2 is more than 6 months old and also because some people mentioned it was related to some type of screen (there are two models) and I was on the "safe model", which apparently is not the case. So today I started to investigate the issue and some people end up replacing the whole screen (digitizer and LCD) which I think I'll do too.
Replacing just the touchscreen seems like the cheapest option since the part costs less than $20 bucks, but I honestly don't recommend taking that path since it's really hard to separate the LCD screen from the touchscreen.
So yeah, the whole screen assembly runs for like $70 plus bucks.
Better waste 50 bucks more then when you need to use the liquid and special devices to stick the digitizer to the lcd, it isn't for people who have never done it before. Its especially harder on newer smartphones then from 2010. Thats also the reason why the nexus 5 digitizer isnt sold seperately since replacing it would be much easier and you wouldnt risk your display when replacing the digitizer.
For that 70 bucks you maybe also have the tools included to open the phone and there are many videos which you should follow carefully to replace it well. I would rather pay 70 bucks then going to some repair shop or service center which replaces it for 130 bucks and above. @in_core If you have warranty use it since dead touch isnt your fault and as I read its common so LG have maybe screwed up it somewhere or the rom caused it :/ but i don't really think the g3 rom caused it since people even get that problem who are fully on stock without root.

Weird screen flickering

Hello,
This is my first post in this part of XDA.
My wife has an s7 Edge and the screen started flickering. I got out of this state messing with the power buttons etc. Mainly getting the touch screen to unlock the phone and it somehow cleared right up.
Is this a software issue? The screen when it came back is working as usual when I restarted the phone it became crap again.
Im think it maybe the lock screen causing this, I never heard of parts being corrupted.
I've attached a little clip of the screen.
Thoughts?
Thanks in advance!

I have never seen this happen before. If I were you I'd flash a new ROM on it in Odin and if it still happens take it to the Verizon store.

Forgot to mention, it's not rooted completely stock.
So screen is messed up?
I had this issue. My phone fell from less than a foot off the ground and landed on the corner. Barely any force, but after that the screen would flicker intermittently. For a day or two it would come and go, and then it became permanent. It looked exactly like yours. If your bootloader/recovery/download mode flickers then it is a hardware problem, since the ROM isn't even loaded yet. With Verizon, your phone is fully covered from manufacturing defects for one year, so you should be able to get it replaced. Sorry bro. Wish I had better news.

Honestly with a screen issue like that, I really recommend taking it to the Verizon store and asking them about it. It seems like a hardware issue to me but that's just my opinion.
My screen has done some weird things as well fresh out of the box. I would have random areas of the screen pixelize until I smack the back of the phone. Even after root It will randomly do it every other month. My father in law had the same exact issue you're having. He brought it into T-mobile where the screen literally failed and went black in the employees hand. Neither his or my phone has ever been dropped. This is definitely a hardware issue. It's almost like a bad connection between the LCD and main board. Make verizon get you a new one before the screen goes black!
Okay...
Is it okay to say I can get a new screen and do that repair myself?
I wanna make sure that the issue I am having is just "buy a new screen and be good to go".
Thanks for your time!
