Just retired my 2 XL and got a like-new 4 XL. Loving it so far, except one nagging issue.
Randomly the top 30-50% of the display stops registering taps (touch). It's easy to fix by turning the display off then back on, but I'm concerned it may be a hardware issue.
Interestingly, when this happens and something that is full screen and scrollable such as a contact list or app drawer is in the foreground, I can drag from below the "no touch area" to the top of the screen, but I can't start a drag at the top. So, it can sense touch in the troubled half, it just won't register taps.
I have done tons of searches. I see lots of people saying Android 12 had touch issues out of the gate, but was supposedly fixed. I disabled the block_untrusted_touches. I have checked any app that has draw over other apps permissions. I have tried with high touch sensitivity on and off. I have paid attention to running apps when it happens. I installed a LogCat reader looking for touch related issues when the problem occurs. I tried safe mode, but due to the intermittent nature of the problem, and the fact that safe mode disables most functionality, it really wasn't a good long term test.
I have yet to pinpoint this.
Sometimes it doesn't happen for a day, other times it's multiple times per day. So trial and error takes time because just when you think you licked the problem, it rears it's ugly head again.
I'm running LineageOS 19.1 at the moment (which I had also run on my 2XL with no issues). It is rooted. No apps force closing or crashing.
Has anyone else seen this on the 4XL?
Definitely interesting, never heard of that. I had some touch issues, specially if the display gets wet where it register touch, but poorly to the point I need to restart the device and dry out the screen. Though in my case the creen is completely cracked, so I suspect that's the cause as it didn't happened before.
Though I had a similar to yours but with the battery.
The problem was that the phone would randomly shut down, and that would happen more often when it was on my pocket.
This made the phone very un stable as sometimes I would have the phone completely off and didn't even know about it.
So I decided to open it and have a look at it. It turn out that the problem was the flex cable that connected the battery with the logic board, it was just slightly tore on one side, but just a tiny I couldn't nearly see it, I had to use another phone to zoom in.
As it was torn, depending on the way the phone was changed the force the gravity made over the cable, causing that sometimes it not enough energy got the phone, causing it to shut down.
Once I replaced it, it never happened again, not a single time.
Maybe you have a similar problem, though as you are rooted and using a custom ROM, that may be the reason, my case was extremely rare.
anyway, good luck

I know that this has been a fairly common complaint about the Nexus One but i'm wondering, roughly what percentage of people actually have this issue? To clarify, i mean the problem whereby touching the screen in one place is actually registering elsewhere on the screen.
I've had this problem since buying my n1 and having to constantly turn the screen off and back on again was driving me nuts. Finally i sent the unit back to Vodafone for repair and they in turn sent it to HTC to be fixed. So yesterday i got it back with an enclosed statement along the lines of "we have fixed your fault etc..".
Three minutes into using the damn thing and the fault crops up again. So much for that! To be fair to Vodafone they are sending out a replacement unit now but of course i'm concerned that even that will have the same issue.
What are the odds?
Here is the same.
To developers: the fact that resetting the screen fix the problem makes me to ask if there isn't a way to make the screen re-calibrate itself every X seconds/minutes, without shut off and on the screen every time. Seems to be until now the only solution to this extremely annoying issue.
It really is a bizarre one. I've seen people discussing whether it's a hardware or software issue but nobody seems to have a definitive answer. If it were a hardware problem, surely it would be constant/permanent? If it's a software issue i would have thought that somebody would have bug-fixed it by now? Especially as it seems so prevailant.
I'm stumped!
Other than this one problem though i am completely in love with this phone. The device itself feels solid, durable and pleasant to use. Android is improving all the time and it always impresses when you demonstrate to the un-initiated what the device is capable of. So close to perfect...but not quite!
EDIT... This from the wiki.. "- Q5: Sometimes my screen registers touches in incorrect places, and I need to turn the phone off and on to make it work correctly again
A: This is a hardware problem, nothing can be done about it. Nexus One's digitizer sucks.
Ho-Hum.
I have experienced this problem on android 2.1 ever since upgrading 2.2/2.2.1, I haven't had the problem. I'm very happy with my screen

That suggests a software problem although i have had it on 2.1, 2.2 and now 2.2.1. I would say that it has happened to me within three minutes of using the phone, 50% of the time within that three minute window. In other words it's cropped up in half the texts/emails i have sent where i have had to do the screen off/on thing to complete the message.
Very annoying.
It has to do mostly with the way people hold their phones, the possibility of registering false touches - including, for example, touching the screen with fingers that aren't completely dry. Some have the issue more than others.
HW issues still can have SW workarounds sometimes. I'm not sure if it's the case. HW and SW need to be analyzed to find one, if exists.
There is no "calibrating" capacitive touchscreen. Resetting its controller might have effects like missing touches and other random screen misbehavior (for example - if the controller is tracking fingers, resetting it would cause it to lose the tracking).
Since getting my phone back from 'repair' the issue is less frequent, suggesting that it's not a usage problem as i'm obviously still using the phone in the same manner as before. Instead it seems that various devices suffer from the problem in varying degrees.
I suppose if i knew what they had actually done to the phone while it was being tended to it might help us discover why the frequency of the problem has been reduced. I know that the digitizer wasn't replaced as the phone came back with the same screen protector on it as it had when i sent it off. That being said, they obviously did something. I just don't know what!
Most probably replaced the phone's MB.
Try upgrading to the latest radio - the issue will probably not be 100% solved, but now I only get it maybe once a month or so...
I may tell them not to bother sending out a replacement. It's happening far less often since it was returned and (going by the poll results), there's a good chance that the replacement could actually be worse than this one is now.
Perhaps the 2.3 update will jar something loose.
ATTENTION PLEASE!!
after flashing miui latest ROM i've never had touchscreen issues anymore in over 20 hours of hard usage (also with the phone in charge!!).
I don't believe is a coincidence, developers please ask miui developers if they have integrated a code to fix this issues.
Thanks!

I have already restored cyano 6.1.1.
However, about "multitouch issues" I mean inaccuracy, the fact that the touch is recognised in another point of the screen (particularly when you press the bottom part of the panel). I didn't verified the axes-inversion issue, but I'm almost sure that it persists.
The "touch inaccuracy" is nothing else than the usual axis-swapping thing. When accidental dual touches (palm/holding fingers/water/etc) happen, the digitizer goes nuts.

I don't think so....I pay attentions when the screen goes crazy. I'm absolutely sure that (in charge for example) my touch is ONE.
The only times I was able to trigger the "screen nuts" effect, were when I was typing 2-fingered, and fast - making it register dual touches. Moreover, sometimes a single touch with a single finger is reported as series of touches. Once it happens, it stays until screen off.

I mean this....since I moved to MIUI this is not happened anymore.
Since I uninstalled Htcime the inaccuracy issues seem less so far! Almost only with the phone under charge ...much much better than before! Dunno why....

I've noticed the last few days that my nc has a hard time unlocking. I start to swipe my finger across the unlock and it moves about 1/10 of the screen then shoots back. If I do it a few times, I might get lucky and unlock it.
Does this sound like the digitizer is going out? It's one of the first production models (wife bought it for me for christmas right after they came into the store). So I don't know if there was an issue with them at all or not.
Everywhere else on the screen seems to be fine, but it doesn't do me much good if I can't open the thing to read the books inside.
*edit
Just did a test on the bottom row of books, and they seem to be working fine in that general area. Is anyone else seeing this only when trying to unlock the nc from sleep/off?
Do you have it plugged in?
Yeah it seems to happen on my girlfriends NC, at least when it was running 1.1 Stock, not sure I've noticed it since 1.2. It's not a bad digitizer assuming you have the same issue which was right after resuming from sleep it will SOMETIMES be a little pokey for the first 20 seconds or so but after that it slides smooth as butter. It never really bothered me since I just assumed it was reloading some software into memory. The only other common issues I know of are issues when plugged in as mentioned above and the seemingly obvious but often overlooked dirty screen.
I do notice in general that both NC's I use are a little less than perfect when touching the far corners (I often need to jab while making grunting sounds) but I figure it's an e-reader so they probably didn't spend a fortune on the capacitive part of the screen. If you are so inclined, loading up CM7 disables the lock screen by default and there might be a way to do it in stock as well although I suspect you will still occasionally need to give it it's 20 seconds to get things running again.
I've started to have touch screen issues the past few days.
Any idea what may cause it?
Sometimes, when I touch the screen, say in settings, I touch one item, but a different item is selected somewhere randomly on the screen.
Happens in TWRP as well. If I select options to wipe, it will select others, and then it doesn't swipe over to execute the action.
No ideas? What would make touches appear where I don't touch, even on TWRP?
I tried the keyboard calibration on HTC's keyboard.
Any ideas? Screen protector?
It comes and goes.
I can't believe no one else is having this issue now.
I don't do stupid things with my phone, like drop it, put it in my pocket and sit on it, and wash it with soap and water.
Since I've started running Lollipop, it appears that my case is causing this issue. I've never had this problem before.
However, I updated my wife's phone to Lollipop Sense and now she is having the same issues with a different case.
Take the cases off, and they work more responsively.
I can only chalk this up to being a Lollipop issue, and hope it will be fixed soon.

I opened another thread about a similar issue I'm having after Lollipop. My gesture launch randomly stops working and I have to reboot. No other issues for me though. I have an anti-glare screen protector on mine, but had no issues before the update. I've thought about a factory reset to see if that would cure what ails.
I'm on tmo but have the same exact issues. This is what i've found so far...
I turned on the developer options and turned on show pointer. This will show you where the touches are landing.
If you scroll down slowly, you can see most of the touches are in line (up and down) and not random on the screen.
I've removed all programs that have screen overlays (screen filter, twilight etc)
I've removed the cases thinking they might be causing the issue, but removing them only slightly improved the issue I thought...
Sometimes its hard to reproduce the effect, its not consistent. So this leads me to believe that it could be a process that's running in the background that calls attention at the moment you're touching the screen, and then refocuses the screen to your point of contact. And in between it thinks you're moving your finger when you really aren't.
In any event, I can't find the exact cause of this. But, it definitely started after the update to lollipop. I had none of these issues before. I even got the phone exchanged because I believed the digitizer went bad or something. But this issue exists on my original phone, its replacement, and now on my wife's current phone and that phones replacement (across 4 phones).
I'm currently working on my wife's replacement (4 or 5 non-oem programs installed) and continue to have the problem. But it is not consistent as I can't readily reproduce it.
What i've done to try and learn more is when I see the screen pointer light up in random places, I keep pressure on the screen so I can observe where the screen is registering contact. It almost looks as if it's trying to pull down the shade. Whether it be because of the dual points of contact and it thinks we're swiping down, or because of another program that is stealing focus for whatever reason.
If anyone else has insights into this, please let us know as this is more than frustrating! I keep calling people in hanouts with a lot of people and they aren't happy about it lol.
Also for reference, we're using ADW ex launcher instead of Stock HTC Sense. But even when I remove ADW (uninstall) and run sense, it continues to happen. So it's not that.
I have the Galaxy S6 ATT with 128 mb. Running stock, rooted, lollipop5.02. Have had it less than two weeks.
Two issues are becoming major. First, the HEAT. This phone gets hotter than any phone I have every had. Sometimes, almost to the point that it is untouchable. I have tried to discern what apps, if any, might be causing this behavior, but without success. The heat seems to come and go relatively randomly; that is, if I set it down for 15 minutes, it will have cooled off and I might not experience the same thing until tomorrow.
Second, and this is equally bothersome. Sometimes when the phone has been on for awhile, and especially if it has gotten warm as described above, the Edge just goes crazy. Pages opening and closing, sliding in and out, keyboard is taken over and types random latters, frequently sending them out in texts. (I've sent many texts that are quite lucid at the beginning, and look like I'm plastered at the end.) Again, a look at 3C Toolbox doesn't show any particular app overutilizing the CPU or anything else that would be apparent to a relative novice like me.
Anyone else experienced this? It's one of those things that is going to be difficult to demonstrate unless it happens when I am right near an ATT store. Any advice will be so much appreciated.
Robert
I've had one of these too on my ATT S6 edge. It's often called "touchscreen ghosting" across different devices that have it. I used to have the OnePlus One which was plagued with these touchscreen ghosting problems. It's exacerbated in high heat environment. You'll find that putting it in the fridge for some time resolves the symptoms immediately. I'd hold out 'til winter and hope they subside on their own.
i was having similar issues. removing my tempered glass helped. im starting to hate this phone. My battery was 66% an hour and a half after i left house today with a full charge. MY gps doesnt ever connect correctly. When using navigation it jumps around and re-routes me constantly. I can't wait to get a nexus 5x and get rid of this junk.
I'm dropping this phone for the Nexus 5x also. I learned my lesson dealing with these phones.

After just having received the Android Pie 9.0 update yesterday, I still have the same issues as since I bought this phone:
Being that after a restart the phone is unusable, as it starts doing whatever it wants, as if there were shadow presses and swipes on the display.
These totally random, involuntary movements, as if I were touching the screen, even though I don't. Those occur so fast that I can only stop it (for a limited time) by pressing the power button (turning off the display and all actions), are totally not something I have ever experienced on another phone before, not even with OnePlus.
I took my case off just in case this would cause pressure on the phone, but it still happens without the case. I propped the phone up so that I definitely don't touch or cover any sensors, but it still happens.
It seems some internal sensor is broken, as this issue still persists after updating to Android 9.0. Unless this might be related to the Nova launcher?
Unfortunately I don't see a way of recording this issue without compromising my personal information, so I can only describe it.
I hope I can resolve this through a device swap through my carrier, but I doubt it. Has anyone else experienced this issue?

Is there a third-party one-button lock screen app installed on your phone? There may be conflicts.

No, there is no necessity for this.
In the fact issue occurs also in Safe Mode as well as after cleaning the system cache (wiped through the menu which is available for soft reset / wiping all data).
The issue got only more and more severe this week and sometimes temporarily froze the screen / inputs and did lead to error messages on the camera app, making it impossible to take photos temporarily.
Huawei referred me to a local repair shop and I will hand in the phone for repair by early next week, once I have organised a replacement phone.
