[Q] Bad digitizer or software issue? Random input. - Verizon HTC One (M8)

My M8 is on stock ROM, rooted with Xposed and a handful of modules.
Half the time I'm in the Play Store viewing a list of my installed apps, my phone will somehow register a touch anywhere randomly on the display while I'm not touching the screen in any way. Initially I assumed it was a busted digitizer, but it ONLY does this while I'm in the Play Store, from what I've noticed at least. My phone does this while unplugged from any charger/cable.
Also, a lot of times while I'm using the phone while charging, the digitizer will freak the hell out while I'm touching it and register inputs all over the screen and very rapidly. I've seen this on other phones as well while using a crappy non-OEM charger, but this phone seems very much more sensitive to what charger you're using. Chargers that worked fine on my Note 2 and my wife's current GS4 make my M8's digitizer freak out. Has anyone else noticed this?
FYI, I can see these random inputs by enabling "show touches" in the developer options. I'll see touches register on the screen without me touching the phone at all in both of the scenarios above.

Are you using any sort of cases/screen protectors? If so try taking them off and seeing if the issue persists. Also wipe down the screen and get rid of any smudges and fingerprints and see if that fixes it as those can apparently sometimes cause this.
Lastly you can try doing a 'Factory Data Reset' from your recovery such as TWRP, I do not know if the stock recoveries have these but if they do and this is a software issue than this will solve your problem. (Requires S-OFF if it's not available in stock recovery)
If doing the factory data reset does not solve your problem than it is almost definitely a manufacturer defect.
Do take note I did my own research just now to bring you these answers and I am not capable of giving you an overly educated answer like someone else may. Good luck! & I hope the software/case solutions fix it.
Edit: Try disabling Xposed and see if the problem persists too.

It's a known issue, phantom touches. It might be software or hardware related. No known fix yet. Happens to me sometimes also. I've also only really noticed it in the Playstore.
Haven't noticed anything with different chargers, you could have a hardware problem.

Using a Supcase that doesn't touch the display and no screen protector. It does it without the case being on too.
I've recently did a full system wipe and tried a new ROM (Clean ROM) and it still does it, but only in the Play Store, which is why it's confusing me as to if it's a software or hardware issue. I've had HTC send me a replacement M8 out because of it and the new phone ( and previous 2 other phones I had hardware issue with) never did this, which makes me believe that it is indeed a hardware issue. It's just bizarre that it only happens in the Play Store.
When I flashed this new ROM though, it didn't do it initially during the setup of the phone and getting all my apps installed/updated. Once I installed Xposed, it did it, so I uninstalled Xposed to see if it continued and it did, so I'm not sure if it was a coincidence that I didn't have any "phantom touches" before installing Xposed or not.

Rooted, no xposed. It was doing the Phantom touches when I was unrooted also.

Just want to bump this to see if anyone else is experiencing it and maybe fine a possible fix. I've replaced this phone 3 times now for different issues and would like to see if I can fix this without swapping it out again. It has gotten a tad worse now and the phantom touches have extended into Hangouts when I initially open it and start typing into a conversation, it will register taps on the keyboard and I have to delete the erroneous input immediately upon the keyboard opening. Otherwise, I don't see it anywhere else in any other apps or situations. Friggin weird. It has followed me across ROMs and factory resets. So I'm guessing it's just a weird-ass hardware issue.

I also facing this issue yesterday & getting worst today. I on ViperRom stock, no xposed or whatsoever.. just viper rom.. this phone just 2 months in my hand.... not only the phantom touches, but dead band as well...
did you send to service centre to get it fix or replacement?

Mine eventually resolved itself. I was only having Phantom touches on Google Apps. Mainly the playstore and Gmail.
Playstore updated and the issue went away, started using inbox instead of Gmail and it also went away. Haven't had a problem since.
Your issue sounds like it might be more of an issue, but updating both of those apps fixed my problems.

Touchscreen Jitter Issue

Ok so i picked up my new skyrocket 2 days ago and I put CWM on it, made a back up and installed the ICS flavor ROM from the development forum. Everything went fine, and i didnt use the phone much yesterday, but today i noticed that i am having annoying touchscreen problems. It basically makes Swype unusable. I have restored back to stock and it was still doing it. I have reinstalled the ICS rom, double flashing it, and it still does it. Is anybody else having issues like this? Its noticable on lists. This video is just an example but it does it in the market, on web pages, etc..
http://youtu.be/x__jdlGXyjk
I have never had these problems. Maybe take it back and exchange it.
Sent from my SAMSUNG-SGH-I727 using xda premium
Update:
I used odin and i reset everything to stock with no CWM and no Root and the issue has stopped as far as i can tell. Maybe i just had a bad download. Ill redownload it again and flash it tonight and see if it persists.
Ok so ive been using stock and it started again. I used an app called Touch Test to see what the screen is seeing. It is a really intermittent issue. There is a "ghost touch" that is happening. near the top of the screen and at the bottom of the screen. A touch in the middle causes it to jump to the top and then back to the bottom causing touches to jump all over the place. It is very intermittent. I didnt buy the phone from ATT so there could be 2 reasons for the this.
A) It was sold to me like this
B) The people at ghost armor put to much liquid on my phone when applying the screen protector and messed up my phone.
I didnt notice any issues before i got it ghost armored, but i only had the phone 2 days before i got it wrapped.
Any ideas on how to recalibrate the screen or any other options i may have?
Found the culprit... Kind of embarrassed it took me this long. Ended up being the wall charger. Its a cheap knock off but it had the same input and output. I was sitting at my desk on the touch test app seeing it spaz out and unplugged it to show my friend what was happening and it stopped. Used the same cable to plug into the pc and no problem. Well that is a relief.

Wow, thanks a lot for this info man! You really saved my life.
I also got a new charger and started experiencing these weird jitters. If it wasn't for this post I would never have figure it out.
My new charger was an Original one from Samsung, but it was obviously made for a different model as the output voltage and current were higher = caused jitters.
I then went back to using my old charger which came with the phone and the issue is gone.
Using Samsung Galaxy S5 NEO (SM-G903F).
Thanks again!!!

[Q] Trouble with the touchscreen? Or is it lag?

Wondering if anyone else has had this problem. I've tried a few ROMs - CM11, Carbon, and currently SlimKat and often (every few minutes) the interface sort of pauses. By that i mean touches are not registered. I've turned on display touches in developer options so i can see when the phone is behaving.
Its very strange because Philz Touch Recovery never has any problems but the phone is almost unusable at many points during the day. Often can't even unlock the darn thing.
I don't think its the actual digitizer because during its lucid moments there is no delay, touches are where they should be etc but then it will simply not work. Most often it involves the keyboard (which i'ves switched from the built-in to the Google Keyboard on the play store as a test). I've run some of the display test apps and am able to use every point on the screen...when its behaving.
Any help is appreciated!
On some Motorola Atrix it was problem with cable between motherboard and digitizer with about the same behavior as you described.

Thanks for the info I'll open it up tonight or tomorrow to take a peek.
Some users managed to find working position of damaged cable. In your case, maybe is just plugged out from connector or contact became dirty.
Be careful and good luck!

MOTO G - Random Unresponsiveness

I have a Moto G and it seems like the screen response sometimes just stops working. When it is working all is well. I have tried few of the touch applications and they are all good. If i put it into sleep and press the power button, i can unlock the phone but no response at the home screen. Sometimes it works great for hours and then would stop. Don't think its a screen issue.
It's out of warranty so sending it back is out of question. I don't think it ever got wet or water damaged. Don't know much of the history on this. Would appreciate the help.
EDIT:
1) I reflashed the stock Telus Rom again last night, but issue hasn't changed much.
2) I disabled the lockscreen (set to none) and seems like it only registers one touch then stops as was the case with the lockscreen. Sometimes it just keeps working fine.
Just trying to figure out if its a software issue or a touchscreen issue. The hard buttons all work fine.
Stock? Which version?
Third party ROM or Kernel?
Does it happen randomly or only while connected to the charger or USB?

Kitkat 4.4.4 Stock Telus/Kodoo Rom.
Happens Randomly.
EDIT: Added some notes above.
If it keeps doing it after a full clean flash then I would bet it's an hardware problem...

Hardware wise is it the lcd/digitizer or motherboard ? Trying to figure that out.
Sorry, can't give any insight on that. I don't even know if there is an easy way to be able to know what of those two is faulty.
Just out of curiosity. Are you in a very moist/damp/humid (not sure what's the right word for this) area?
Do you have sweaty fingers?
I'm asking this because I also feel kind of an unresponsiveness whenever the screen has any moist on it or if my fingers are sweaty.

Messed-Up Display

Hello XDA,
My Nexus 5 running CM12 5.0.2 nightly will not respond to the touches anymore infact when I press the power button to activate the display it acts as if someone is touching it randomly messing all the apps that are running and opening and closing many other things.
Furthermore it displays weird and burned lines throughout the screen. It was not dropped, no water went inside the device or anything. If it helps I did install the OTA updates that CM gives us.
I have also attached pictures so you may get a better understanding of my problem.
Thanks in advance.

Hmm I see. Well since a month HAS passed, its definetly not the rom thats causing the problem, i don't know if anything regarding the software could even be causing the problem. Its 100% hardware and by that i mean the screen, you should change it, the touch and also the display are messed up.

I hate to be the bringer of bad news - but your screen is toast. Fortunately you can replace the touch and display components all at once.
http://www.amazon.com/Skiliwah-Digitizer-Assembly-Google-nexus5/dp/B00HN0U168
Here is what you need to perform the repairs - and here are the procedures for disassembly.
https://www.ifixit.com/Teardown/Disassembling+Nexus+5+Display+Teardown+-+liquid+damage/32410
Trust me, it's not that difficult. Unfortunately, it's a bit pricey ($60 for the screen and digitizer), nevertheless much cheaper than a new device or sending your device in for repairs.

Problem Solved
The screen isn't toast, neither is the digitizer. I have 2 of these phones. The parts which cause problems like this are the main board and the ribbon with the USB connector on it, which also attaches the screen & digitizer to the main board. One was showing lines exactly like this, & also no touch. I put a replacement main board in. Works great now. The other, wouldn't even turn on. I put the main board from the first phone in the second one, it still wouldn't turn on. I replaced the ribbon cable, it turns on and perfectly replicates the issue from the first phone. So now, I have one fully functioning LG Nexus 5, and another which turns on with the same problem as yours. This is good, I started out with 2 of them that were useless to me. So, it appears that your display and touch issues are caused solely by a bad main board. A replacement main board costs somewhere around $75. After swapping stuff around, I have 2 bad main boards, 1 bad USB ribbon & 1 working phone of 2. Not bad, not bad at all.

Digitizer not responsive sometimes

My U11 is having problems recognizing touches. The digitizer itself is fine when I check with testing apps or the developer options. However in normal everyday use, I find myself having to repeat actions quite often, maybe once every 20 touches. It's not really consistent... sometimes it's like the phone expects you to be REALLY precise when tapping a button or text label. In other cases light touches are not recognized until I try a 2nd time. And sometimes I try to open the navigation drawer by swiping from the left edge of the screen and again I have to try a second time.
The phone works perfect if I am really careful when using the screen, but in my previous HTC phones (M8, 10) using the screen was completely effortless so this is a bit odd.
Anyone experiencing something similar?
I've noticed the same thing. thought it was me. I get it sometimes moving icons around and other times. I'll keep track of when and how and report.
I may be able to test with a 2nd unit in a few days, I'll see if I get the same issues.
It does feel like a software calibration issue rather than a hardware one though. I have the "show taps" option enabled in dev tools now and the taps are definitely being registered, it's just that the actions are sometimes not triggered.
Same here. Sometimes have to tap 2 or 3 times.

The same problem here

I have the same problem; most prominent when my hands are too dry, and worst at navigation buttons under the screen. Maybe use the glove mode?
Just updating the thread to say that the phone is now working a lot better. I still get the odd tap that is not recognized but it's not nearly as common as it used to be, the phone is perfectly usable most of the time now.
Not sure what changed, I came from a M8 so maybe it was just a matter of getting used to the new size of the device (the way you type does change quite a bit with these larger screens), or maybe there were improvements in the software, I went from 1.03 to 1.13 a few days ago.
Same issue on 2 household U11
I just got the phone about 2 hours ago. I agree sometimes touches don't register. Very annoying.

Same here as well, thought I was losing my mind. Also I can be typing something and it will trigger the pull down notification tray up top, weird. But it's very inconsistent. I don't recall seeing this before the latest update.
Sent from my SM-G955U using XDA-Developers Legacy app
Same for me, hopefully some update will fix it.
I don't think an update will fix this. The issue was so bad I asked for a replacement. Unfortunately, it will take over week to get a replacement. HTC Customer Service takes forever to respond, then shipping phone back, and then getting replacement.

My second unit has the same problem so I would say replacement is not a solution. I hope they can fix it by some SW update.
Same problem here. I just did a factory reset last night to fix a different issue though so I'll see if it's still happening.
Have also touch issues and will now repair this from HTC.

I was going to hard reset this morning as well but didn't feel like setting everything back up so I will deal with it for now. But if it fixes the problem then I will for sure. So let us know how it goes for you.
