[Q] LG G2 Touchscreen problem needs few clarification from devlopers/friends - G2 Q&A, Help & Troubleshooting

Hello to every one, I purchased LG G2 2 weeks ago and i can say there is also and not also issue withe the touch screen.
1> When i keep the phone on the bed below there is nothing which act as a conductor, it is resting on the bedsheet at that time upper right corner of the handset screen dose not responding, BUT when i take the handset into my hand it starts responding in the same area where it failed to register when on bed so, is our body having any type of relation with the handset screen (Screen guard is there on the phone and has been replaced twice)
2> When i remove the screen guard then on bed or in hand the screen use to respond properly and efficiently.
Any suggestion will be helpful to me and others also.
Thanks in advance

if yes then it is a hardware problem return for service they are going to change the front of your screen and it will be fixed like mine.

Touch Screen Malfunction, need HELP!

Good evening... Well recently, i bought a Screen Protector from ShieldZone for my hermes. Well I applied it to the screen and so forth to the rest of my device, then i realized the touch screen doesnt work. I take out the battery for a few minutes, and it starts to work, but after a few seconds, it stops working again. Any suggestions?
This happened when i put my first screen protector on too.. What happened is you put the sticker on to tight; there is an equal pressure over the entire screen , so the processor cannot distinguish your pen touch from the rest of the matrix. All you have to do is take the protector off and reapply it with less force and it should work. (It took a few tries on mine to get it right, did the same thing on my wife's Treo 750.)
well,sounds strange,did you align the screen properly??
Im using a not so costly screen-protector on my hermes without a problem.
Probably u may remove the shieldscreen and make sure dat its not a hardware issue,good luck
yeah i took off the screen protector and still i have the same problem. Anyway i can change the pressure settings?
well,Im not sure about pressure settings but you may try re-aligning the screen (in settings) ,it shud help mostly,hope u have warranty which is not void...
I had the phone unlocked, and I put in the latest Cingular OS, even though i am on the TMOBILE Service.
I have the wierdest thing happen this morning!!! I woke up and turned on my phone, and there is a little smudge in the center of it. Almost like there was a air pocket between the protector and the screen, so i took the protector off, and it was still there!!!!!!!!!!!! So, i pressed down on the little spot and it moves around just like an air bubble would. I turned on my phone to see fi there would be any problems and for some ODD reason, everytime i tap the screen it smushes in that spot. It looks like when you press on the lcd screen of your computer and the pixles kinda move around a little!
Was wondering, I have a Cingular 8525 and would this warrant a repair? Meaning, Could I call them up and tell them what happned and they would send me a replacement?
This is really getting frustrating... I had this phone for only 8 days and its already giving me a headache.

Touch screen doesn't function

I need your advice...
My Touch Screen doesn't function, I cannot dial out, Faulty LCD or Touch Screen (or both), While I click on the screen it doesn’t respond or it has a shift, I click on the top of the screen and it actual click on the middle of the screen.
I have no problem with the display - it display everything and correctly with full color.
What I think is that I have a problem with my touch screen.
Did anyone had a problem with the touch screen and replace it?
What is strange, when I hrad reset the device, on screen alignment process I have no problem to click on the cross, but it takes the device up to 3-4 times to aligen the device.
I want to order the touch screen part and replace it, I don't have warranty.
Do I need to replace the LCD as well or just the touch screen? Either way it will be cheaper to buy them both then to send it to repair.
when the backlight is off...and you hold the phone 20 cm for your eye`s and turn a bit up and down in a room with light...can you see a oil film on the screen...???
that is the digitizer....sorry german english..

When the backlight is off (black screen - the device is on stand by) - I can see only black screen and my reflection...

I ordered from the same store "keep_beauty", and they already shipped it, I looked in your recommendation and his guide.

Lower part of screen stopped responding

After 4 months of flawless work, the lower part of the screen (a strip several millimeters from the edge) suddenly stopped responding properly!
E.g., all buttons in this area (including launcher/phone/+ on home screen) either don't work at all, or sometimes activate after a while when strongly pressed with the thumb (orientation doesn't matter).
Just two hours before they responded fine to the index finger.
Also, I've noticed that when I "multi-touch" the lower line in a file browser with two fingers, it works nice! Buttons are too small for that, however
I first tried to restore backup, but it didn't help, of course.
Has anybody had the same problem?? I guess it's a warranty case ...
I would agree, it's probably a hardware problem that you'll have to bring your phone in for service to get fixed.
I'm having that same problem my self, but just now and then. What helped with me is that I press the upper left corner of the phone with my other hand and then the lower part works fine, so i think i should get a new digitizer or its just loose connector.
im having the same problem , i have put up with it for the past few weeks and its driving me nuts now. today i did a factory reset which made no difference , i called htc who didnt sound a bit suprised by my phone call it gets picked up tomorrow morning to go for repair so the question is ... is this a common fault? and how the hell am i gonna cope without my hero in my pocket ?
Yeah happened to mine last week, a few have had the same issue where it's just the launcher bit not responding. Although the good news is that I'm getting it back tomorrow though so it's good times!
I had the same problem with my touchscreen (after a month or so!)
Mine got picked up thursday by HTC and I just checked the tracking site and they just recieved it.
I wonder how long it's going to take
Visited their service center last week.
They've immediately replaced my screen with a new one without any ado. Now everything works as before!
BUT a friend of mine who bought his Hero in January is having similar problems now...
It is a common problem according to HTC.
Mine was repaired in just 10 days.
Same problem here, did htc said anything about this problem? is it a common fault?
thank you
I said it in the post above yours.
ah yes, right, thank you

If they acknowledge it officially, couldn't you provide a link please?
i gave mine last week to repair, they returned to me unfixed. on the paper stated that they only updated the software, what a dumb this htc guys. need to go back and tell them again the same story. im wasting my time only for this. wtf
I recently had this problem. The 3 buttons at the bottom of the screen wouldn't respond, took it into T-Mobile who said I'd have it back within about 7 to 10 days... 3 weeks later I got a text saying I could collect my phone...
On the paper sheet it says they've replaced the lens.. Which I can see they have as before I had a miniscule hairline scratch near the top.
They also mention a software update (1.0.0.A6288)
Either way it works nicely now.
I've recently experienced the same issue - the lower part of the screen, the one where the LauncherPro icons usually are stopped responding to touch. If I press really hard it works sometimes, but it's pretty annoying. I didn't sit on the phone or drop it recently, it just stopped working all of a sudden.
Is there anything I can do, as the phone is out of warranty ?
HTC South Africa gave me a new hero after I took mine in for the 3rd time. Hardware problem. Very happy with their service.
i have this exact same problem, is the only solution to send to htc? >_> Cuz my warranty's out already unfortunately... i flashed my hero to CyanogenMod 7 and it seems to have helped, but still not completely responsive... I also have a problem where at times i completely lose control of my touch screen where the spots i touch seem to respond to opposite sides of the screen... anyone else?
Remove battery, Remove sim card. put a dryer on the htc logo for about 40 mins. put the phone under a heavy object. Let it dry for about 15 mins and your fixed.
^ wtf do u mean?... are u just being a gimp...

Some help trying to fix a Motorola Defy?

Hello, I have a Motorola Defy, that I dropped a few times, so the LCD screen got damaged with blue dots on it, I made a mistake and thought that the problem was on the touch Screen, so I purchased a replacement, installed but, it was damaged, the touch did not respond correctly, I wasn't able to type correctly among other problems.
I got a refund, then ordered a LCD screen replacement, now that I have it here, I install it, and it's broken:crying: I know, bad luck and being a rookie while trying to fix my phone, ok, I put back my old (damaged) LCD screen to use it in the meantime, and the old touch screen, but now, the old touch screen that was supposed to being working fine, it doesn't, it has the same problem as the touch screen that I bought.
Question is: the problem with the touch screen, could be related to the damaged LCD screen? or the motherboard of the phone is damaged? the phone works great, the apps, the games, everything but the touch screen and the LCD screen, but, as I said, I went back to the default touch screen after using the damaged one that I received, and it works worse I don't know what's wrong, please help me out, sorry for the long post
Please post questions in the Q&A section. Moved there.

Is this true?
true. fix some minor dead pixel if you put in freezer for one day. but your case... im dont hope much.
Try changing LCD + Capacitive Digitizer. (after trying the freezer trick ofcourse)
Well i will tell my story, which is related to your's as well,
i had a phone with resistive touch screen and it got screwed up, that is it does not respond correctly. So, i took it to the service center and they replaced the digitizer (touch screen) saying that previous one is broken. But, luckily the new one didn't responded to any touches they make.So, they replaced it again with the old one quoting that "your phone can't be repaired". So, i took it home with me.
Later i thought to calibrate the screen but the old one is not responding any more, no matter where i press
Later i calibrate it with the help of a software for windows mobile with the help of a PC. It took me to the calibration screen, from where i calibrated it, and voila, it worked... as good as a new one :victory:
long story short,
i think when you disconnected your digitizer, phones default values/drivers got messed up and are unable to find the new or the old digitizer you connect. I suggest you to go to the service center as these screens can not be calibrated.
Is there NO WAY at all to recalibrate the screen from the phone itself? or using an application? the delicalibration might be the problem....I'd like to fix it myself :/ thanks for the tip, never heard about it before!!

I replaced my original digitizer screen for the one I ordered it, it gave me problems, so I went back to the original one, which was working fine, and now it's not fully responding, that's why I'm assuming is something calibration related, thanks!

[Q] Need help with screen

Ok so basically I love the g2, but here is my problem, bare with me on this haha, BTW its completely stock n everything as its my 1st Android phone so didn't want to mess with it. So basically I broke my phone screen in January, bought new screen, followed a YouTube tutorial, replaced LCD+touchscreen, no issues super happy, had the odd issue where if I woke screen, would only be on for a second n then go back to sleep, but then upgraded to KitKat through computer software update, still nothing wrong, upgrade fixed the issue with the knock to wake, and then my worst day, smashed the screen again! On good Friday, ok I thought I'll just replace screen again, so I did, but when I put new screen on and tested it, all was well, until I made a phone call, the instant moment I press green call button, screen goes blank and won't come on no matter what, power button don't bring it back on or end the call, but I can hear the other person and they can hear me, had to turn phone completely n back on to be able to use it again, so I though hmmm dodgey screen, but just to be sure it wasn't the phone I put damaged screen back on, and the issue didn't appear, stayed lit up while in my hand, went off next to my ear, back on whole in hand, so I took it to local phone repair shop because I couldn't be bothered going through the hasstle getting refunds etc, they replaced screen, I went and tested it before paying them, guess what, same problem, so what exactly is going on? Has KitKat made the phone not work with a new screen other than the one I upgraded it with? I'm seriously confused and need some bodies help urgently my model is an unlocked lg g2 d802 16gb now I turned it on last week before I took it to be repaired, and it says I have software updates but I didn't bother installing them, is there a chance these could be related to my issue and possibly fix them? Its driving me nuts tbh
Chris
Hey Chris. It seems like your proximity sensor is messed up. I think the new screen you got yourself is worse quality or your damaged the proximity sensor when installing the screen.
Edit:
Please go into your phone app (where you call people) and type the following
3845#*802#
Then go into: HW Device Test and then ALC proximity test. Try testing your proximity sensor with your hand. It should change from far to near when your hand is about 2 inches from your phone. The proximity sensor is located next to the camera.

Ok thank you I will try that, I also thought a damaged sensor but when I put damaged screen back on after having the issue with my new screen it worked just fine, no blank screen when making a call, I retested it before I left it at phone repair shop, still was fine, then picked it up with a new screen and issue came back, I don't get why its been like this, I'm thinking bad quality screen and maybe try scratching the sensor area of the new screen to allow more light in? It may be to dark for it, what exactly do I do if it works fine when using that code, try another screen?
Chris
I doubt it will work when you use that method. It's just to make sure that it's the proximity sensor that's the problem and not some loose connection. And yes, a new screen would be your best bet.
Sent from my LG-D802 using XDA Premium 4 mobile app
Ok I won't try that method then lol, what if it doesn't work when I use that code, as I said I didn't have the issue with the damaged screen which I tested after having the issue with the replacement screen I'd purchased, so how do I know its not just the screen not allowing the sensor to see? Is there anyway I can reset the sensor to relearn maybe?
Chris
If you follow my steps, nothing bad will happen. It's just a way of troubleshooting the proximity sensor. I still think you should do it.
Sent from my LG-D802 using XDA Premium 4 mobile app
Ok I've spoken to phone repair shop and they agree it worth a try to see if its the screen or not, I'll let you know on Saturday after I've been and tested it
Chris
I just had this exact same issue.Turns out the inside of the screen was just dirty. I opened it up and took a q-tip to the inside of the screen and it worked perfectly after that. Also check the readings of the light sensor, as it is right next to the proximity sensor, if the screen is the problem it will likely have low readings as well.
Great I'm glad somebody else has encountered this issue, its been driving me nuts lol ok so I dial in the code that's been mentioned and what are the labels in the menu for the proximity and light sensors? I'm thinking its just a crap screen as the broken 1 worked fine after I put it back on after testing new screen, and I reckon the screen the repair shop has used is also ****e quality, but I just want to cancel it all out as I don't have the phone to hand to inspect as they still have it lol is there a picture somebody can post up to show what to not cover when replacing the screen and applying adhesive tape etc? Just so I can show them to make sure they have done it all properly.
Chris
Ok so just to update the problem, I went to the phone shop today, did the test, it was showing near all the time, but the light sensor reading was quite high, 166 or something, but I then tried squeezing the screen, index finger on back and thumb on front, gently squeezed it, and proximity sensor started showing far, and near as I moved my hand over it, but after few seconds, went back to showing near constantly, so I think its the screen not been seated, told the shop to take screen off, give it a good clean and reseat it. This sound good to you guys?
Chris
Anyone?
Bump! I'm only wanting a little extra advice so I don't end up paying more money out for another screen when it could possibly be proximity sensor? I think it was just the screen not seated properly, anybody have an idea or something else to either assure my choice or point me in another direction?
Chris
