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?
Hi guys,
I have a pretty disturbing problem. When I use swype gestures to type a word, whether with Xperia keyboard or with (my preferred) Google keyboard, sometimes the gesture is interrupted although I do nothing to provocate it. I can not reproduce this bug - it has nothing to do with the speed of swyping. I already turned off the option for having a space when hovering over the space bar. It happens every three minutes or so, but I do not know why.
Does anyone know this problem? Any solution?
I am on 4.4.4, 14.4.A.0.108, Kernel: 3.4.0-perf-g0109737
I uninstalled Xperia Home Launcher, using Google Now launcher only.
Thanks a lot!
same here, IMO is an hardware problem
I flashed a complete new ROM with a new kernel, and the problem persists. That is incredibly annoying.
Any idea how we might get rid of this?
same here. it makes most games unplayable
Using a matt screen protector was the solution for me. Had no interruption since.

remove the screen protector that is factory installed and install another one? Which one did you installed? (Amazon link that may be you can share with us?)
Thanks.
Nope, I did not remove the factory installed screen protector - just used the screen protector like you would with any other phone.
I ordered this one: http://www.amazon.de/mumbi-Displays...d=1407017702&sr=8-5&keywords=z1+compact+folie
Unfortunately they are out, but I guess any other matte screen protector will do it also.
I had no issue since putting it on.
I have recently received my G3 32GB (855), however, I noticed the screen is not responding to all touch screen inputs. Id say it responds 8-9 out of 10.
For the record, I'm running all stock, no root, only ART enabled.
I even went to the hidden menu to check double check if there are any faults, but it was correctly recording every time I touch the screen.
It feels like the UI is not responding sometimes...
Any suggestions?
I've noticed that today on mine as well for the first time. Double tap to unlock has been very hit or miss, even with a reboot. I'm totally stock and didn't switch to ART yet. Not too happy about this and will keep monitoring.

If your not looking closely, its easy to assume that it was due to lack of proper contact.
But when I started noticing this issue, I started paying attention to each screen touch and then I felt that I had some misses...

It was to the point that it didn't work on first double tap, didn't work on second double tap, and I slowly and methodically did it a 3rd time with no luck. Had to use the power button on the back. After a restart its only done it once since....kind of weird.
I'm not facing any knock on problems usually, it actually responds more than my G2 I have to admit.
My main problem is swiping thru the launcher.
Even inside apps I can't recall any prob, it makes me feel like it could be related to launcher lag...
I just installed Nova and I'm no longer facing any issues with the launcher not responding to certain swipes. I guess there are more optimizations required for the LG launcher ui
I am having the same issue. I did install one of BodyGuardz tempered glass screen protector. I have art and I am rooted with towelroot.

Not the solution you are looking for but, I have to say, this was the case also on my G2 and G PRO 2. It's an LG thing. Not to bad by any means but noticeable and something that should be sorted.

Maybe you're right about that, I still have my G2, but its running cloudystock 2.0 and Dorimanx Kernel v5.8, so it feels like a different beast.
my phone touch is not as responsive as it should be like my old samsung s3.Anyone would like to tell me how I can increase my phone's touch sensitivity?
Any help would be highly appreciated///
You mean like it's not as responsive? Such as when you have to swipe two three times to accomplish something thwart normally takes one swipe? Go into your developer's option and turn on the option where you can see the colors that responding to your touches. See if everyone you touch the screen that a trail if color follows the movement of your fingers in the screen. I'm trying to figure out if your issue is software or hardware. If it's software, you may need to reinstall the ROM you're using. Else if it's hardware, you may need to replace the digitizer. As for now, you can try clean the screen, and get an iPad compatible stylus, which is more sensitive to the touch than the human fingers, since our fingers are dirty, and they leave dirt and greasy residue on the screen. BTW, how and when did you started to notice that your phone screen was less sensitive?

What do i have to do in developers option Please elaborate if you can?
I recently got this phone so comparing to my s3 I think the touch is a bit laggy.Its not all time but for a mere second like when I play games like subway and temple run at some point the touch lags.Also when my phone is in pocket and I receive a call or text sometimes screen stops responding.
I am currently on G3 optimus g8 rom.One more thing I recently flashed bliss rom 5.0.x.In that rom the touch stops working till I press the power key to lock my phone and then unlock it and it starts working again.
I don't know if this is a rom thing or digitizer?
Any help from you would be nice.

You know, in the developer's options, under input section, there is an option for showing the touches, such as ever time you touch the screen the color will show under your finger, which tells you if every touch you do on the digitizer screen has registered or not. If you get a color response every time you touch, but the command seems to lag, then you may have to flash different ROM. But if color doesn't come up every time you touch the screen, then there may be something wrong with the digitizer. If you purchase a second hand phone from an unknown owner, the digitizer screen may haven been replaced before without you knowing it. Try different ROM first, such as blisspop 3.2 or vanir's newest nightly, which are lp 5.1.1.

Now everytime I touch screen a pink mark shows with the whole led flickers shortly every time I touch that happens.I think the digitizer is quite okay because every time I touch the dot shows with pink flickering.What is your opinion on this?
And yes you are right this is a used phone.
It sounds like your hardware is okay. If the lagging responses are only occurring sporadically, then you may want to think flashing a different ROM the solution. Also, if the digitizer is working, sometimes when the screen is dirty, or if your fingers are wet, that will all cause the touch response to lag. Try using a stylus, and see if that helps. IMO, using a stylus on this phone makes the touch more precise and responsive. Besides the touches being unresponsive, do you notice anything else is lagging, such as when opening up an app?

Thanks again for your time.
I dont see any lags in apps etc.I will try some other rom and see what happens then.
One more thing with this phone is that its camera pics are blurry at the top and bottom and sharp at the centre.it gives a miniature like effect to pics.the focusing is not accurate.It seems that its lens cover has been replaced.Do you think its a hardware fault or maybe dust particles on the inside lens.
Any idea what might be the cause?
Try different camera app, if issue persists, try clean the lens, this phone is easy to take apart.

Same here! All of a sudden my screen goes crazy, as if three fingers are touching the screen at the same time. Quick fix: restart the phone.
I waited reporting the issue to see if more people have it, or it is just my phone.
Hmmm... now that I think about it, I better wait rooting the phone and tripping Knox in case of fixing this problem under warranty...
Same problem on my phone. I have a glass screen protector, I thought maybe it's because of the screen protector. Sometimes locking and unlocking the phone also solves it for me.
I also have a glass screen protector, but I experienced the problem also without protection, since I applied the screen protector a day later.
Locking and unlocking the phone seems to "solve" it as well indeed.
Hmmm... seems we got an issue here, Samsung!
I have also addressed this topic to the online shop I bought the phone.
Ghost touches did happen to me during the first three or four days after purchase. Now however, they are completely gone.
I've had this happen to me two times in three days on two different A70's (one time on each phone). Most likely software issue.
yes me too, i can't even type fast bcs it will trigger a ghost touch between the two alphabets i'm trying to type, feels like an old man for typing slowly lol

I'm also having the same issue. Tried the 1st solution. (https://forum.xda-developers.com/galaxy-a70/help/ghost-touch-t3927693/post79538651#post79538651). However my phone didnt restart automatically so I restarted manually. I'll update the results. Thanks a lot.
Got a software update this morning which seems to have fixed it. At least I got to type this comment faster :laugh:
guys, I don't know if it's a "ghost touch", but if I get my finger really close to the display it acts as if I touched it on that spot - but I don't feel like I've touched the screen at all... is it really sensitive or is this the ghost touch issue?
