Phantom or Ghost Touch Screen LG Optimus G

yawako · Apr 20, 2014

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

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

.....

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://xdaforums.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?
