Dead Screen Touch - G2 Q&A, Help & Troubleshooting

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.

Screen issue

I've had my Mogul for about 2 months now and everything was fine until 3 days ago. There is a section on my screen in the middle on the left side that is not responsive at all. I tried to realign the screen, but that didn't help. I tried reflashing my phone...that didn't help either. I didn't drop the phone or anything so I can't think of what could have caused this.
You guys think this is software or hardware?
i dont know about the screen
but you should try one of the 23007 6.5 roms
on spb3 i was holding 18-20mb no problem and they are fast
maybe a new rom will help the screen issue
(i've since ditched spb3 for more memory and i'm well up over 20 after usage)
(note#2: spb pocket plus uses less memory than spb3 and is another good option with different features)
Thanks, I'll try that ROM or any other ROM file just to see. I don't think it's the ROM itself, since I've been using this ROM for over a month and never had an issue, but I guess it's worth a try.

It sounds like hardware to me. If I had to make a completely uneducated guess, I'd say it's a broken digitizer. I hope I'm wrong, though.
Your best bet is to relock/reflash to stock and make a warranty or insurance claim.

Wish I could but I can't make an insurance claim...this is a Sprint Mogul flashed over to work on MetroPCS

So i sent my nexus in for repair

it arrived yesterday at htc repair and ive been watching the repair tracking site. i had some pixel problems, like a quarter of my screen was darkened grey.
Keep in mind my phones bootloader unlocked, rooted, haha and i sent it in as is running the latest miui. Why? idno.
Anyways. I just checked the repair site and it says:
Ticket Information
Status: We are repairing your phone.
Service Type: Repair
Issue Description: top screen is darker that the rest of the device
I havent approved to pay for any repairs for an out of warranty phone. So i guess im off the hook right? I think im about to prove that htc repair people dont give a F***!
THought id share..
Uhhh, we have known this for a year now. It has been proven time and time again that HTC will warranty repair hardware defects, despite an unlocked bootloader.
This is nothing new or surprising.
Did someone has problems with the multi-touch screen: lags, do not respond or random reactions ...even when having a call ?
the solution for now is to push "shutdown button" and it seems to reinitialize the sensors for the screen ... isn't it weird ? It occurs 40% of the time ...
The menu for reinitialize sensors/calibration do not exist (for HTC Legend/Hero you can re-calibrate the sensors).
Do you have same problems ?
I will send it for repair soon...
im having the same problem, ive had it for a long time now, ive gone threw 20 Roms. so i know its not software related, or is it something the devs are over looking??
weird thing ....do Googlers have same problem when demonstrating navigation/goggles/phone calls/voice recognitions .....or do we fall on bad series ???
definitely hardware problem or something no-one has been aware of ....?

Sometimes it's worse than others, I think if the phone is running something pretty intense it happens more often. Otherwise, no, there's no calibration. Calibration doesn't make sense on a capacitive screen.
The touch screen issues have been known since the beginning, and the solution of quickly turning the screen off and on has been known for just as long.
It's part of the hardware, and most if not all Nexus owners experience it once in a while.
Getting a warranty replacement for that will not fix anything, it is a flaw in the hardware design.
Good thing to know that...but really weird for such a device...they probably think about it when starting/choosing next nexus.... ;-)

I'm curious whether they'll return it with a relocked bootloader and stock ROM
i've noticed that the only time i have touchscreen response issues is when i use my N1 without a case on it and it seems to be because some of my fingers touch or get near the edges of the screen glass. i have a silicone slip on case and when its on the phone it prevents me from touching the glass accidentally at the edges and i never experience any response problems when its on the phone. just my 2c.

yeah that would annoy the crap outta me as well, glad mine does not exhibit this problem.
i'd love to guesstimate how old mine is but i'm the second owner, it might be possible that they fixed this hardware issue in later build revisions or it could just be a random problem with the touchscreen/module, some do it and some don't idk.

was it amoled or slcd though lol
i have to make the call when i get up. today my usb port was gone from the phone when i went to plug it in tonight. i never used to have the screen issue, it slowly started happening and now it happens all the time, i lay it flat in my hand and i hit a button on screen and my menu pops up etc.
nice to see a recent time frame though, i'm dreading going without my phone and having a dumbphone replacement. would love to know if it was amoled or slcd you got back though, thats my one worry

[Q] just purchased a g2 for $30. screen doesnt turn on

The phone definitely boots up because the lights on the buttons flash on then turn off after some time. The keyboard also lights up. You can tell the backlight turns on on the screen, but there is no picture.
Anyone have any idea about what I should do? Thinking about trying to restore to a stock Tom somehow tonight. Then I'm thinking about looking for screen replacements.
I was curious if anyone has had this issue before.
Update 07/14/11
So I got the screen and switched the old one out for the new one. This one also only has the backlight turning on, but I noticed when I put a part back on, there was a little bump in the middle of the phone. Haven't had a chance to fix it, but I noticed it's a piece hitting this rubber piece that seems to "transport" the sound for the mic from the bottom of the phone to the actual microphone module within the phone.
Removed that rubber piece, and I'll try installing it later. I was getting some blue and red visible in the middle of the phone. Anyone know what's wrong?

ebay for the parts and look around for the link for repairs. I don't exactly remember the link, but it's in one of the "spring replacement" threads. Good luck

How sure are you it's the LCD screen? Replacement screens cost more than what I bought the phone for...lol
it's mostly the physical connection to the screen.
and on your note about it costing more than what you bought the phone for... there are tons of parts on the phone that will cost more than 30bucks. not much you can do about that since you got it non fully functional.

Never had to do it myself, but there is a cable connecting the two parts of the phone. That is usually where this problem originates from. It's not easy to fix though if your not familiar with fixing electronics from what i have seen.

I've taken apart my laptop completely and put it back together before. Completely as in taking the lcd off and different chips and wireless modules and stuff. I think it may be something I can handle. I'm going to take a look at it now. Restoring wont do me any good because not even the boot screen shows up.

So I completely tore apart the phone, got to the point where if I had another LCD screen, I could have easily switched it out. But I don't, so I just put it all back together. I really hope this new LCD will fix the issue. I really hope it's not some other motherboard issue. If all else fails, it goes up on eBay for $70-$100 as is for the phone. If I fix it, I just got myself a phone that goes for $200 used for only $57.
sure. goodluck with it. if you can do it then you're all set. good luck

Only $57? That would make the lcd screen $27 if u really paid $30 for the phone, but you said the screen was more than what u paid for the phone...so now im confused.

Sorry. After some searching on eBay, I found some sellers selling it for a few dollars less than 30, e.g. 27.
But I decided to go with a seller who sold more than 200, who claims the screen is an OEM screen, and who is top rated. He sells his for $32. Which makes my phone $62 after all is said and done.
The housing has some scratches on the top and bottom though, which decreases the value a bit, but hey, if it works I'll probably keep it as a backup. Currently have the HD2, but I got a Vibrant with original box and accessories for $100, so I think I'm going to sell the HD2.
That was kinda off topic, sorry
LCD screen should be here by the 13th.
Updated OP
someone help =|
I don't own a G2 but I still think this could be a similar issue to what we get over here on the HTC Droid Incredible. First, what makes you believe its still a screen issue if it lit but just didn't throw picture? Usually thats the symptom of having the wrong recovery version for the device hardware version. Normally for us what happens is we will get somebody who is new and rooting for the first time and they'll end up flashing the wrong recovery or freak out because they don't realize the root process takes a little while and yank the cord. End result being exactly what you've explained above. Phone starts but no screen. So we end up having them do the ruu or a second option which we call a "blind install" where you drop whatever your p file(ours is PB31IMG.zip) so whatever it is for the G2 drop that on the SD and reboot to hboot and do the update process by simply knowing how long to wait between key presses and what keys to hit without useing the screen. Its a unique process and all very magical. Haven't lost a single Inc yet because of this issue.
Anyways bud just a thought...

It doesn't seem to be a ROM issue.
Update 7/18: Sold the G2 on eBay and still made a good lump of money. I was very happy, until another G2 popped up with the same exact issue. Got it for a steal as well, and I tried the OEM screen I got from eBay, and it was still having issues, and it seems to cause the phone to overheat while charging. Definitely a defective screen and someones getting a great deal on a decent condition G2 because I already took the payment after I figured it was the screen I got.
I'm going to try to get a replacement from the guy that sold it to me on eBay, but I already left him positive feedback thinking it was the phone's fault.
Will update probably late July or early August when all of this gets sorted out.
TL;DR: bought 2nd g2 with same issue, turns out replacement screen didn't work in the 2nd g2, too late to not sell the first g2, getting another replacement screen to fix 2nd g2. First g2 was in better condition though =|
SWEEEEEEEEEEEEEEEEEEEEEEEEEEEET
Just installed the second screen that I ordered, and it works PERFECTLY. Phone is perfect nowwww yay. I can't use it right now though, previous owned put a lock pattern on the phone...

[Q] [HELP] Digitizer vs some weird BUG ?

for the past week my screen has been going whacked out on me.
the on-screen buttons would start clicking on their own, and sometimes the screen becomes unresponsive,
BUT
when i turn it off, and back on, it would work perfectly fine .
so i basically get a 50/50 chance if the screen going crazy on me...
now if it was the Digitizer, wouldnt the problem be ALL THE TIME?
as opposed to being random, could it be a BUG ?
Can anyone please help or advice, thanks !
If a factory reset doesn't fix it it is probably hardware. I have seen intermittent problems with digitizers before.

Read the book that came in the box. Manufacturers defects pretty much always have a 1 year warranty.

I have a similar-sounding issue (on-screen buttons flashing wildly, et al.); I am thinking of opening the device to check on connection
Is it more or less likely, in your experience, that the connection between the display assembly and the board is loose from impact or whatever, or that the digitizer itself is just defective?
Thanks for your help.
I had the exact same problem on my device and it can be due to two reasons.
1. If your phone get extremely hot during use then the screen starts behaving abnormally.
2. If you had dropped your phone then there is a slight chance that you have damaged the digitizer.
I had the second problem and I have replaced the screen and it is working normally again.

[Q] Nexus 7 Touch screen problem

I got touchscreen problem with my Nexus 7. My touch screen is not responsive. Sometimes it won't read detect my finger.
I took it to Asus Service Center and they change the main board with the new main board.
When I got it back, my N7 back to normal. But after 50 hours, my touchscreen become not responsive again.
I tried to upgrade it to 4.3, and its still the same...
Now I'm using CM 10.1.3.RC, Android 4.2.2 and nothing changed. My touchscreen still unresponsive.
Is there anyone know how to fix it?? :crying:
Since they should warranty their work, they should fix it again for no cost, or give you a replacement.

When I took my N 7 to Asus SC, they said they replace my mainboard with the new one in August 2013. Do I need to take it to Asus SC one more time? Is this hardware problem or OS problem?
Since you went through 3 different operating systems I'd say hardware.
No matter anyway, all they need to know is that it came in to be repaired for a problem. They charged you to fix it, the problem came back after 50 hours.
It's not fixed, and it's their job to do that, not yours.
Simple.
