Unresponsive Touchscreen - Galaxy S 5 Q&A, Help & Troubleshooting

Anyone having touch screen only issues? There's not a single crack on screen, I've always treated the phone very well.
I'm thinking whether I should replace the whole front, but curiously only my touch screen is not working, display is OK and works well using SideSync. Also, the entire touch screen starts working at random times (I haven't been able to figure out the conditions, it's not hot/cold or pressure; I've used a hair dryer, a refrigerator and heavy items on top of it).
In fact, it worked for a month after it started malfunctioning (initially it didn't work for some hours, and then worked again). But now it got worse again. It's not software as I've tried XtreStoLite and now I'm back to stock. Should I replace the whole thing?
Oh, I have the G900H.

Sounds like a bad digitizer. It would be wise to shop for a new one before it goes out completely.

Touch Screen/lcd leaked? touch not working.

Howdy folks... i will try to get a picture up tomorrow...
Basically a few days ago i picked up my phone and noticed a marble type effect on my screen, very similar to when you put inks into water etc.
At first i thought the lcd screen had leaked etc but my (actual) screen looks normal, no missing pixels or screen errors
It happened again few days later and then this morning my gf removed it from her pocket the whole touch area was like it... and still is now... 10 hours later...
Could water or moisture build up between the touch part and then screen???
During the time it happens the touch area doens't function at all!!
Any ideas or thoughts at all??
Thank you all very much in advance!!
dont know, but this happeded on my touch ELF and is happning on my touch 3g now, not happy might try a few crazy things before replacing the digitiser il let you know if anything works.
Heres a pic attached...
Cant really see it but maybe help to see the issue?
Can kinda see the outline of where the marble effect starts... and you can see the purple and lights green/blue effect its left..
I wouldn't mind but the touch screen doesn't work kinda making the phone useless!
tried a few things, like freezing than heating, worked for a while, calibration kept falling out. put it away and went back to my elf. tried it yesterday and it hardly responds to touch at all, responds randomly when you press it haaaaaaarrrddd.
might be time to get new parts
Looks like the touch screen sensors are out of sort. My experience with my previous model (HTC Kaiser) similar thing happened. Changing the screen solved everything, works like new.
I had problems with the touch screen on my touch 3g and tryed everything (hard restarts, screen aligns, millions of times) until i changed the digitiser in htc service and everything works fine now, like new as azahidi said. Good luck.

Next time I recommend you use the search function... This has been discussed several times.
But yeah, you are not alone... This is a common problem or defect on the LG G2 (all variants). A few days ago I got the same problem where just a part of the top of the screen does not respond to touch.
As far as I could tell, the only solution is to replace the whole screen assembly or just the touch screen, but the replacing just the touch screen requires so much delicate and specialized work since the screen and the touchscreen are glued together so I recommend investing on a new screen-touchscreen replacement that will set you back about $80 USD but easier to replace by yourself.
I've been trying to figure what could have caused this on my G2 since I've never dropped it, but there are two possible scenarios for me:
1. A few days ago I was on a call on a very VERY hot and humid day, I was sweating like a pig and when I was on the phone, I noticed the receiver stopped working due to sweat coming into the speaker. I was stupid enough to blow into it trying to clear it, of course it didn't work but once it dried, the speaker worked again.
2. On a few occasions, I have forgotten to remove my phone from by back or front pocket when climbing into my car. I could imagine the phone would flex just a tiny bit and figure that might not be good, even though it was really not that much pressure nor time.
Those are the only two possible scenarios in my case. Other than that I don't see how it could have failed.
Cheers!

[Q] Touchscreen Randomly Stopped Working

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.

left side screen glitched

Hello,
The left side of the screen shows some Missingno type glitching (I've attached some pics)
Does anyone know where this type of problem comes from?
I had the screen replaced and it worked beautifully afterwards for a couple of days...
I also installed system updates.. so I'm wondering; is this a hardware or software issue?
Thanks for your time and interest

Happened to my wife. Needed to be returned and fixed, hardware glitch not software. I am not sure if it was a screen issue or some other hardware.

Did you have the screen replaced because of the screen flashing, or did the flashes start only after you had the screen replaced?
If the problem has been consistent over the course of two different screens, it would point towards a hardware fault on the sending end of the display connector, right where the ribbons leave the motherboard.
If this problem is brand-new, it might just be that the display connector was not fully secured when the new screen was installed.
Mine is doing the exact same thing. Left side goes all grey and static looking.
I took it apart and reseated the screen ribbon connector and at first I thought it made a difference, but now it continues to glitch out. I took it apart a second time and it has the half screen right at boot up. Sometimes it goes away just setting on the desk but seems to come back regularly. Its only the visual part of the screen, the touch points are still all in the same locations. And when I took a screen shot while it was glitching, the screen shot came out normal. So I am hoping its only the screen/digitizer that is going bad.
I am going to buy a new screen and see if that fixes it. Its only $60 on eBay and its pretty simple to take apart. I will post back if it fixes the problem. That way if someone else has the issue they will know.
Moto x style display problem
I have got the similar problems with display and I will return for warranty repair. I will tell you later what happened.
Downgrade to Lollipop , It worked for me.!
...
(This is the tip for everyone)
I replaced the screen and that seems to have fixed it for now. I haven't had much chance to use it since the screen replacement though. I will update in the next week or so and let everyone know how the screen replacement holds up.
The replacement screen only lasted about a week and now the righthand side has glitched out. I am going to take it apart and put it back together but i think its time for a new phone.
These phone are getting cheap and I really like it so I may just get another. Although the lure of a dual sim version is attractive.

Touch screen occasionally unresponsive

Hi,
I own an Oneplus 2 for over a year now, in which I had to replace it's display two times . The first time I ordered a new display+digitizer assembly and replaced it myself, went great and everything worked fine. The second time was a month ago, I ordered the exact same display from the exact same seller on Ebay and did the replacement. I tested the display before assembling the Phone and it worked as it should. But an hour later when the phone was already assembled I discovered that the touch screen was completely unresponsive
After some trial and error I came to this conclusion:
the problem seems to be caused by applying a mild pressure anywhere on the bottom right quarter of the screen
the display does always respond when I hold my finger on it (with or without applying pressure) for about 4 seconds, then it sees my finger and I can swipe around (while still holding it down)
if I try the method above a few times, or let the phone rest on a desk for some time, the problem disappears and the touch screen works fine again.
So far, it looks like a hardware-issue, maybe a faulty screen or I messed something up while replacing it. But it gets weirder:
My OP2 is rooted and at the moment of replacement, it was running Lineage OS 14.1 (nightly, 2017-03-30). And when I wanted to update that to it's newest build, I realized that this whole touch screen problem doesn't exist in the TWRP recovery interface. It worked perfectly fine even when I tried to recreate the problem by applying firm pressures on every spot on the screen. So this made it look more like a software-issue, however the update of Lineage didn't resolve it and even restoring my backup of OxygenOS 3.5.6 didn't help.
I found this XDA-post about having firmware issues for the touchscreen with Android 7, but running their fix did not resolve anything either.
Right now my phone is pretty unusable since having it in my pocket is creating the problem. :crying:
Does anyone have any ideas of what the exact problem could be? Or anyone having similar issues? Why is it that there is no problem at all when booting into recovery (TWRP)?
It looks like loose connections between the display and digitizer.
After all it was a hardware issue. I disambled the phone again and after a lot of trial and error I found that there was something that came in contact with the back of the lcd that must have created a short cicuit or something. I placed a thin sheet of paper on the back of the lcd to prevent this and it all worked again! Still weird though that it didn't happen in TWRP.
