[Q] Please Help: Part of Screen Unresponsive - LG Optimus G Pro

My E980 has a portion of the screen that does not detect touch. If you divided the screen into 5 equal parts (5 at the top and 1 at the bottom), it would be the 4 and 3 regions. The area above it works fine, and the bottom 2 and 1 regions work fine.
I have the phone rooted and running an AOKP based rom. When it had the stock ROM that same region was also unresponsive.
Any ideas you may have to fix it would be appreciated.
Thank you!

Try this.
Reconnect digitizer if you are confidant to play with hardware.

Thank you for the suggestion. I will try to just replace the digitizer, and we will see if that fixes it.

Screen Problems

I just had my screen glass only replaced after dropping and cracking.the screen.
The problem I am having is there is one area of the screen that does not function intermittently. It works fine appox 60-70% of the time - others it does not. The area is in the location where the "T" is located in the default Samsung keyboard.
This happens with the stock firmware as well as a couple of custom roms.
I am not an expert by any means but I thought this is a software/calibration problem.
Anyone have and ideas?
Thanks very much!

I hope your warranty is still active, it looks like it's a defective lcd/screen with
intermittent pixels if this problem appears on all screens not just the keyboard.
If it's only the keyboard, re-download the stock official Odin flash S4 firmware
from SamMobile.com and flash it using Odin.
Good luck!

Phantom or Ghost Touch Screen LG Optimus G

Few days earlier I started to notice this problem after 5 months of use of my device. My screen starts rapidly shaking left to right and front touch panel stop working, it happen when I freshly open an apps. To temporarily fixed it, I have to press power button to turn off the screen. Is it a hardware or software problem?
Did you flashed any rom or kernel?
Do you use trickster?
Some people sayed that uninstalling trickster solved their ghost touches on the keyboard (may not work in your case).
I had a similar problem and was because of a kernel.
If you had modified anything try to use stock for a while and see if the problem persist

Stock, I guess I should wait for official kitkat. Dont have time thinkering my fone atm.
I was ghosts touches on my screen. One was pressed on all sides. To fix it I had to turn off and turn on the screen. I decided to change the touchscreen and the problem was fixed. Now it works ok.
Sorry my english.

I bought it on ebay. Screen+touch+ frame. This option:
http://pages.ebay.com/link/?nav=item.view&id=111278902215
But You can buy other options.
1. Touch + screen+ frame (medium dificult)
2. Touch + screen without frame (best option)
3. Only touch screen. (very dificult option)
Many people have told me that the best option is 2, without frame to not be taking off parts that are originally attached to the frame.
You can see totorials on youtube
Ghost Touch now keeps rapidly pulsing at the buttom edge of my screen (portrait) my phone is sometimes uncontrollable. I never thought this kind of newer high end device gets broken so easily under short period of time. I never experienced this from my good old Galaxy Y, Xperia mini and X8 that I accidentally deep under water even now still working in mint condition. So sad with LG products. I was planning to buy LG G Pad but because of this I probably get Nexus 7 instead.
Im going to sell this for $155
Reflash it again with stock firmware twice, problem still persist
Its now a hardware issue
Touch screen seems deteriorating overtime. At first Ghost Touch, then on the next day a dead touch portion just above the home screen panel where the ghost touch first occurred rapidly moving back and then after few days a ghost touch appeared again just below in the middle of the screen (portrait) then after an hour probably about 1.5mm size thickness dead touch. Now a I have 2 horizontal dead touch portion of my screen and probably more to come if I keep using it.
Few days ago i'v got first phaton/ghost touch problem. I used Omni 4.4.4 so
- reflash to clean OmniRom (try few kernels) - the same
- flash to Android L Preview - the same
.....
fu***
Install - ARTMod ROM so 99,9%of stock - and as for now all its ok.
Strange.
Update:
One day and zero problems.

Please, can you post the link from the exact same rom?
I've got so many ghost touches on an exact same point my screen (I posted that on another thread on this board) that made me got another phone, typing was impossible (the touches were on the left-down corner, right on swiftkey settings -_- )...I've tried many many roms, but nothing worked yet...
Thank you a lot!

OK, this is freakin' weird...
I have been running KitKat on my F180S pretty much from the time it got released (different versions: full stock, VDT, Sling...). Yesterday, out of the blue, my digitizer started getting crazy with ghost touches in the upper portion of the screen (around the strip where Q-slide apps usually are in the notification shade, or the clock area on a weather widget where most people have it). This made the phone 100% unusable, as it was constantly registering touches. Rebooted to recovery to do a factory reset, and the problem was persistent in the recovery, too (I am using PhilZ Touch). So, at that point it looked like a hardware issue to me. To clear my consciousness, I opened the phone, disconnected the digitizer, cleaned the connectors, plugged it in again. No dice. Still, I thought about reflashing a full stock KDZ, just for the heck of it (no root, no custom recovery, locked BL). Here is what happened:
1. F180S V30c KitKat - same problem.
2. F180S V30b KitKat (downgraded a notch) - same problem.
3. F180S V20n Jelly Bean - everything is working fine, no ghost touches. Huh?!?
4. Rooted V20n, unlocked BL (Mako method) and flashed CWM using FreeGee - no problem, everything is still OK.
5. Flashed my favourite JB ROM - no problem, everything is still OK.
So, the phone is now running on rooted JB, with unlocked BL and CWM recovery, with no touchscreen problems whatsoever. I may try going to KK again at some point, but will just leave it for now, as I need a stable working phone.
WTF??? I am just scratching my head, trying to understand where the issue came from. It appears to be directly related to KitKat, since eliminating unlocked BL and custom recovery didn't solve the issue, but going back to JB (either full stock, or unlocked BL with CWM) totally cured it. The most bizarre thing is that it started out of nowhere, as I didn't do anything to my phone recently, apart from installing some apps here and there...

Yeah... But at least in your case the problem seems to be consistent. I was using my phone without any issues, and then it just crapped out for no apparent reason. Nothing changed, same ROM that was working fine before...

It started the same way for me.

The same thing happened to me. Are you guys familiar with Sky Vega phones? I had a Vega Iron before and also it began having ghost touch issues after upgrading to kitkat. I was frustrated, i also flashed any custom rom i could search and no luck at all. I just sold it recently! and i heard this ghost touch issue is also a common on Nexus 4.

Hello everybody,
I have the same problem with my LG - ghost touch and dead zones on the display. First installed the ROM from this link - http://forum.xda-developers.com/opti...te-10-t2811342 , but the issue still exist.
Then change the display with a new one. Dead zones vanished but ghost touch doesn't. Tried some other ROMs even the original stock ROM.
When I installed the new display the ghost touch is mostly when I use Facebook Messenger.
What can I do in this situation?

D855: Top of touch screen not working

Hi,
Since I flashed my LG G3 with LG flash tool, the top touch screen area doesn't work, making me unable to use the notification area.
I tried with a touch screen test application and about half centimer is not working in the top.
Somebody already encounter this?
Hey, you mean a part of screen is simply dead? I've had a very similar problem, only with my phone it was the middle of the screen, like on the video i recorded - https://www.youtube.com/watch?v=q_R1aGVUWhs
If your phone is on warranty, send it for repair, because it's probably faulty digitizer. If not - there are 2 options. 1 - pay for the repair of the damaged digitizer (or it could be simply not well connected, but you won't be able to tell yourself because the lcd and digitizer are not separetable, at least in theory, because it is possible, but highly unsafe). The other option is what I decided to do - you need to get a lighter with a one click button and do the same as this guy does - https://www.youtube.com/watch?v=VERfODYHX3g. It worked for me, at least it works temporary, but I heard if you do it a couple of times it will work permanently
Thanks guy!!!
It worked with me too!

Touch issue

I am not sure if it is touch issue or display issue. https://www.youtube.com/watch?v=JdMbbML9ECg Please have a look at this link.
The touch works for 2 seconds of screen on. Anyone having same issue? Please reply if anyone has fixed this issue.
same problem.
It's like the smartphone, after a 2 second make a check then blocks the touch.
I noticed that if I touch the screen before turning on the smartphone, the touch does not hang after 2 seconds but after more than 2 minutes.
I'm not sure it's a hardware problem; I still believe that it can be solved by preventing the above control.

Which ROM and Kernel are you using? Should be a kernel related issue, try flashing a different ROM or Kernel.

I had the same. I used a piezoelectric of a lighter to give static shocks to the screen while touching it with the other finger. It worked.

I had the same issue, and fixed it by removing the screen protector. Now the touch has been working since yesterday

I am also facing the same problem on my phone.
I tried discharging the phone completely and charging again.
I use the original charger only.
I'm running Pixel Experience ROM on stock kernel. This problem started a week after unlocking and rooting my phone. I also feel that it is not a hardware issue.
The problem started with the nav. buttons: The rest of the screen functioned properly but the nav buttons were unresponsive. A little later (a few hours), the entire screen responded to touch intermittently, and after that it responded only a few seconds after unlocking the phone (the above mentioned problem).
I am having a very tough time as this is my daily driver and I'm stuck.
Please Help. Thanks a lot in advance.

This is exactly what has happened to me too. It started with the nav. buttons and then the rest of the screen. Have you found out what is to be done?
Guyz try a cell ,u know those 1.5 v cells use them as the s pen im not joking it really works u just try once
No solution whatsoever!! I just cannot believe this is a hardware problem. My screen works (most of the time) for 2mins if I wake the screen up while touching it with one of my fingers, otherwise the screen works only for 2 secs.
This problem has been discussed in very few places although there are many people who are affected. Loosing hope.
Can I exchange this phone on Filpkart/Amazon in India?

I exchanged my z2 plus with this problem on Amazon without any problem. They only want a phone which switches on and whose display is not cracked

Exactly how did you did that? Could you explain?
Broke a piezoelectric lighter and got the raw mechanism.
I made it discharge several times on the affected area while touching another area of the screen with another finger

Workaround
I tried one workaround indicated by someone else on another thread. Follow below steps
Press power button to put screen off
Hold phone in left hand and put left thumb on screen
Press power button to start screen
Touch with right hand fingers
It will work till left thumb is there on screen..
If touch is lost follow from step one
Atleast this helps alot instead of only 2-3secs stuff..
Thanks to one who indicated this workaround
Found a solution
Hi I was also facing this problem and I was ready to give up then I tried changing custom ROMs and when I installed the dot os v2.4,the problem disappeared and I was back to using the device normally
Hope this helps

Software issue. What setup are you running currently and what have you tried?
Thanks for your reply. I have formatted the phone twice, removed the tamper glass but nothing happens. problem is still there.Downloaded Oreo 8.0 Ver 5.0.2 and installed the software but still problem is there.I think there's problem with Oreo update.some times I can't restart or switch off the mobile because of touch problem.
Please find my details and help me.

Same thing only it is with the bottom 1cm of my screen, it is intermitent except directly above home button where the screen more often doesn't work then it does...
I enabled touch tracking and when it goes wild the dots show up going left-right for about 2-5s and then it calms down, except for example when I get into E&A game when I click on a part directly beside home button I see two dots "spliting" my touch into 2 dots maybe 0,5cm left and right, then it usualy goes haywire.
I use US version of DASH charger with EU adapter but seriously doubt that can be the problem, I'm not the only one having it obviously and it seems most of us got it thru Oxygen OS (well I just bought mine, used and updated, about a week ago so...) and I'm really anoyed by this, a 300€ used phone having such a CRIPLING BUG!!!!
