touch screen issues

Anyone else having their touch screen stop working property until they have to reboot? It's like it gets way off on where I'm actually clicking.

I have experienced that, but only after I had flashed the modaco rom. I basically returned to stock firmware this morning and am having to re-root my phone...

I have had a couple of occasions where it doesnt seem to respond correctly.
For me its like it looses the calibration, seemed to noticed it when the device is tilted horizontally.
reboot sorts it, only happened once or twice though.

If the phone is in your hand, make sure your other fingers aren't curling over the screen around the edges to much.
I noticed this happening, and backed my fingers off around the edge of the screen and it started working fine immediately.
I think the screen is just extra sensitive.
Curious if that helps.

I read somewhere (maybe on this forum even) that non-multi-touch systems have this problem. Have the same issue with my HTC Magic, but after a while you learn of a way to use the device single-handed while not touching the screen.

I dont know if this helps or not but I have no idea what you guys are talking about

The calibration problem (the screen registers a wrong spot than where you touched) comes up if you try to use a non-multi-touch phone single-handedly, so part of your palm (between the thumb and index fingers) touches the edge of the touch screen. Especially if you are trying to reach a top area of the screen while holding the phone with just that hand, likely some part of the palm touches the bottom of the screen.
If you want to try having the problem, you can touch the edge of the screen with a finger and try to click a link with another. It won't register the right spot.
Supposedly the problem should go away as soon as you lift that body part up from the screen.... so I don't know if this helps the OP or not.

same issue

does not look like its happening all the time. Ran few tests and still can't duplicate the problem in order to find the cause. so far this happened about 3-4 times on my phone.
i hope this gets resolved soon and that its not the touchscreen issue.

I've had this exact thing happen to me a few times. I notice the tip of a finger on the edge of the screen, move it, then it works fine right after. Sometimes happens with the base of my thumb hitting the bottom left corner too.
Just make sure you're not accidentally touching any of the touch area and it'll work fine.

I have had this same issue on my G1 as well a N1. This problem only happens from time to time, as happes with stock ROMs and custom ROMs.
For the N1, I was initial pulling the battery; however, I have found that if I hold the power button down (don't let go) and then touch the screen to unlock or power if off.
I have a friend with the Eris who was having the same problem; Verizon released a patch earlier in the week that seems to have solved the problem for him.

You can perform a soft reset on the Nexus One by holding volume down, the trackball, and pressing the Power button on top. A half second later, your phone will reboot.

I am also having these touch screen problems, and I can confirm I am not touching any other part of the screen to have it interfere with the non-touch-screen interface. I been testing with what people has been saying on here with having any other part of the screen being pressed, so I have been testing it out and I can say its a different response then what I'm experiencing.
Here is what is going on with my nexus one:
1) it happens at random times (my device is on my table and I am pressing buttons with one finger)
2) it only affects the bottom-left portion of the screen when it happens, touching everywhere else is fine
3) it thinks I'm pressing an area around the soft keys, an example is if I press 'A' it thinks I press either the '?123' or the 'back' button, same if I press 'd' it thinks I'm pressing the 'menu' button.
I can conclude that since not all nexus one owners has this problem it is a device issue, which what is going on is probably the same as if someone was accidentally pressing a part of the screen, but it could be part of the device is assembled incorrect or deformed. The physical form of my phone is off on the right side, I can feel the gray plastic part next to the black border next to the right of the screen is a little more raised then the left side.
But there is my experience with whats going on to me and my two cents.

Ive had this a little bit on my device as well, but I think it's a software issue since it went away when I pressed the home button.
edit:
Also it has happened exclusively in Dolphin browser

here too
Sporadically, it happens with my N1 as well. When pointing at the middle of the screen (in a list for example), the input registers 2 cm below my fingertip. Rebooting fixes this temporarily but it is annoying.
A SW update could perhaps cure this behaviour?

I just had this happen for the first time, all my presses were registering way below where i was touching, tilting into landscape in an app then back to portrait fixed it for me.

So now it happened to me too. I have the Nexus One for almost two weeks and I never had the unresponsive touchscreen. Of course I noticed that the center of the softbuttons is shifted upwards and that they don't register very well in the middle where they should and I had the problem before that the sms text input box didin't registered in the center so that the keyboard wasn't popping out but that is all only a problem of adjustment. Today in the morning after my phone was on standby over night I put in the charger to charge it and I got an email with pictures. I scrolled through the email and all of a sudden the screen became totally unresponsive. I tried to scroll and the screen registered at a complete different place. All of a sudden the email was gone because the phone registered the delete button even though I never pressed it. I could close the gmail program but I had a hard time to scroll between the home screens and the live wallpaper became unresponsive too. I decided to do a restart but I had a hard time to press the shutting down button because it was unresponsive too. This all happened not after heavily usage of the phone but after maybe 1 minute usage.
I am sure that I didn't touch another part of the screen when this occured because I realized before already that the screen becomes wacky if you touch it at two different places (lack of multitouch, so stupid to disable it). I hope that this is a software issue too. I can live at the moment with the 3G problem because it doesn't stop me from using the phone. The unresponsive touchscreen scares me more because because it becomes completely unusable.

i've noticed this with low battery. Twice its happened to me, the first time was when i first recieved the handset. and secondly was this morning when my phone was off with no battery again.
anybody want to leave their battery to empty out and try test if this is correct?

I've had this happen a few times in the ten days i've had the phone. I always make sure I'm not double dipping on the screen, and its easy to do since it will exhibit this behavior for a few minutes.
In my experience battery level has no effect on it.
A reboot always fixes the issue.
I figure it's software based.

[Q] Touch Screen Problems

Is anyone else having problems with their touch screen?
It will occasionally become unresponsive, and other times will just start 'clicking' repeatedly in random spots.
I find myself having to turn the power off and on (via the button, not a hard power cycle) to fix the issue. Its starting to get annoying.
Anyone else?

Yes, I am getting the same thing but I've found that if I just turn the screen off and then back on it fixes the problem. I don't need to reboot.

You think this would warrant an exchange? or is it just how its going to be?

I've put several hours on mine, but haven't experienced this issue. I don't know, if this happened to me more than once, I probably would exchange it.

It was happening to me all the time. I had to get a screen protector and haven't happened since.

Very good "solution" to what should be an obvious problem. The Nook Color has a *capacitive* touch-screen. If you get "junk/gunk" on the screen, it's gonna cause you issues. I find this to be the case while holding my NC and playing Flight Director for a while. The issue: My hands become sweaty and as a result of the slight film of sweat/oil on the screen, the NC's ability to measure the capacitive changes on the screen (and react appropriately to them) is compromised.
Keep your screen clean and you won't have this issue.
Note: after you wipe the screen down (damp cloth, etc), you will need to click the power button and go the lock screen and then back into the NC before it works right directly after cleaning the screen. The dampness of the cleaning cloth throws up the calibration enough to cause very strange things. My experience with "correcting" this issue tells me that in some way, the NC is recalibrating itself when you go to the lock screen.

johnopsec, this has been my experience as well. After cleaning the screen from finger-jam i don't get the phantom clicks. I also noticed that because I live in a very humid climate (Florida panhandle) there will be a thin moisture layer buildup sometimes and it really helps to wipe this off. I also have an incredible that does not have this problem but it has a screen protector which, I am guessing (and as gigadigit expressed), fixes the problem. Just make sure the screen is clean and dry before applying!

screen response
Also,
If you are holding the side of the case by the screen this throws off the touchscreen, I was having the issue where it would be clicking and multiple letter inputs when typing.
Also when it is laying flat and you have the power cord plugged in you may get multi letter inputs.
The trick, hold it by the back not the sides.
and if you have it plugged in and need to type don't leave it laying flat.

I have experienced this problem and loosely seen it correlated with moist fingers.

no moist fingers here and on my 2nd nc. this ones starting to have the ghost touches too.

My Nook Color started acting up after paying levels 3-4 to 3-6 of Angry Birds. I'm not sure if Angry Birds caused the issue or not as I haven't gotten it to do it in another app. I'm running 1.4.2. Doing a lock and unlock fixes the problem until it returns.
I managed to get Phone Tester to run after it got into this state. I made a video of it using a crappy webcam. There's a stuck finger in the corner.

Touch Screen issues while unit is plugged in..
It seems I have read on some forums that some people have screen issues.
Personally I didn't experience this until I tried to use my NC while plugged into it's wall charger.. It seems to act as if it has a grounding issue, which is not the case when the unit is unplugged.
So when you are running your multitouch or touch tests, do it without the unit plugged in..

I have had the same problem with my touch screen. I have the nexus live wallpaper and whenever you touch the screen it sends off the animation. Well sometimes it just goes non stop and sometimes opens up the window where you can apply a widget. I guess the most practical solution would be a screen protector but if not ill restore it and send it off to B&N

There's a small little app in the market named "Nook Screen Recalibrate" this app is super simple and easy to use. I hope this helps
https://market.android.com/details?id=com.assid.android.nookrecalibrate&feature=search_result

Here is the issue I have...
Right is the N button side. Just a reference point for this.
Reboot the Nook (I use CM7).
Bring up the keyboard
Touch Q in the center - you get W.
Touch Q on the right - you get W
Touch Q on the left - might get Q but you usually get W.
Recalibrate using the Nook Screen Calibration (above).
Q now gives Q unless you press on the right side of the key. I also notice I still have to hit the back arrow more to the left or I bring up the keyboard.
I've learned to live with it, but the left side of the touchscreen is slightly off and you have to touch to the left side of any object on the last 1".

yeah, for me it's the edge of the screen along the right side. it's less sensitive then the rest of the screen. I found that calibrating 2-3 times really works best.
There's also a fix in the nookwiki, but i can't get my adb to work on my laptop, I think its the drivers.
http://nookdevs.com/Recalibrate_the_NookColor_touch_screen

What is the left and right side?
I should have said that left is the side opposite the N button.
I downloaded Multi-Touch Screen from the market and I can see part of the problem is the angle of my finger. Straight on it's better.

Nook Color Touch Screen Problem
Having similar problem as described, after two years. Extended warranty expired ... two weeks ago (of course).
Tried cleaning screen, no help. Have not tried screen saver yet, but will.
In the meantime, I notice the comments about touching the sides, and I noted that as well.
Is it possible that this could be helped by opening it up and re-seating the case? Has anybody tried this?

[Q] How do I disable orientation-initiated screen sleep?

I'm not sure if I'm describing this correctly in the title so let me try and elaborate -
I've used probably 10-15 different ROMs for my Nexus 10 and lately every single one I try, I have the same issue when I have the screen titled down horizontally towards me while reading in bed ( think holding it up while lying on my back, angled down at me so I can read ), where the screen blacks out/goes to sleep.
Then I have to tilt it back so it's vertical again and sometimes it puts me at the lock screen but more often I have to hit the power button to get the lock screen back, infuriatingly I then sometimes get stuck in a loop of hitting power to get to lock screen as it's going back to lock screen so then it kills the display again so then I have to hit power again etc etc. Once the screen is back and displaying everything is fine until some random amount of time ( between 5 seconds & 5 minutes ) when the screen just goes black again - presumably when I move/adjust my position or the angle of the screen.
Anyway - I believe this is version independent, I don't think it's the ROMs, it's like it's something built-in to the OS.
The only thing I can figure is it's either related to the accelerometer detecting that I'm tilting the tablet horizontally so the screen is facing down and thus it is killing the display, OR it's the light sensor detecting a darkening of the light since I would be angling the screen away from a direct light source and so it kills the screen thinking I'm placing it face down on a table.
Possibly related - I've also noticed since 4.2.2 ( maybe coincidence ) that I can't rotate my screen 180 degrees and be able to unlock the device. No matter what, if I flip that sucker around it instantly kills the display and locks the screen. I've got auto-rotate on, so I know that's not the issue, and if I hit the power button to get the lock screen up, then unlock it INSTANTLY locks again and kills the screen. It's like there's a setting now that says I CAN rotate if I want to but there's no point because I can't actually unlock the screen to do anything. Keep in mind this ONLY happens when flipping it 180 - if it do it 90 or 270 and have it vertical there is no issue, it is literally only when it is flipped 180 that this occurs.
Am I over thinking this or is there something really, really obvious I'm missing? I've gone over every setting I can think of and the only thing remotely screen related is the sleep timer but it doesn't matter how long I make it or if I even turn it off entirely - every time I get into bed to read I have to mash the power button to get the screen going again. It's minor in the grand scheme of things but it is incredibly frustrating when all I want to do is read before going to sleep, just stay open damn it !

I hate to shameless bump this but does anyone know what I'm talking about? If I tilt my N10 past a certain degree ( I want to say it's around 30 degrees or so ) the screen just goes to sleep, how do I stop this? I've used a ton of different ROMs so it seems to be something consistent and/or a fundamental "feature" of JellyBean and/or Android in general.

If nothing else, I would say it rather "seems" to be a hardware issue, because I've never seen this behavior on my own device. That said, I can't say I've heard of many people talking about this either.

Thanks for replying! Good point - I've just assumed it wasn't something specific to MY N10 because I can't imagine why it would happen from a hardware perspective since it's never been damaged ( dropped, scuffed ) in any way. Unless I just got a bad egg with a faulty accelerometer or light sensor or something, which is also possible.
I suppose if no one else is experiencing this and it's isolated to me and is ROM independent than it must be hardware. Either that or when I'm laying in bed I generate large bursts of electromagnetic activity that cause it to think I've closed the "smart" cover. :cyclops:

Screen Timeout
I don't know if any of this matters, but I am just curious.
What is your Screen Timeout setting? Have you tried increasing this? Do you have it set to lock screen upon pressing the power button? Have you tried changing it? Do you use a pattern lock, pin code, other?

My screen timeout is set to 10 minutes, though it doesn't seem to matter what I set it to - I just set it to 30 and the same thing happens after a second of tilting it.
I have screen lock via slide, but while I do lock/kill the screen via pressing the power button I just realized I've never actually set it to do this. I guess I thought it was a built-in feature - I've just gone through all the settings I have ( currently using FlamingMonkey AOSP ROM for reference ) and I don't see any option anywhere to enable/disable this feature. :S
Maybe there is an issue with my power button and when I tilt the tablet it jiggles it enough that it "presses" down and locks?

Use ultimate rotation control from store and force the lockscreen to landscape at all times.

I think that you are on the right track. The option to lock the screen on hitting the power button is under the Security settings for stock android. It should be there for your ROM too.
I constantly hit my power button when sitting it down or picking it up. That is why I disable the instant lock option.

Weird burn-in issue on cm13

Hello, been visiting the boards for a long time, but I didn't register because I had nothing to contribute really. <.<
I currently have a i9505 running on cm13 6.0.1.
Last night when I wanted to reply to a text I used the right side lock screen shortcut that's set to messaging the circular motion thingy messed up the edge of my screen. (I didn't realize until later that it's not actually a hardware issue if you ask me.)
Some pictures, screenshots don't register anything:
CAN'T POST IMAGES because I'm a new user. :/
It's on imgur, with /a/Murqy extension after .com. Album of three images.
Messaging shortcut thingy on the second screen is a lock-screen burn in, as is lock screen in the middle of the first screen.
Sorry for the garbage quality screens, I don't have any other spare phone except for the ancient Sony Ericsson with me atm.
At first this obviously looks like some display issue or a burn-in. I've checked the display, it has absolutely no scratches.
I've also read about the quality issues of some S4 phones and glass+display being glued together which can lead to yellowish tint. And how display breaks easily because of bad build quality and too much pressure being put on the display itself.
Anyhow, ever since that brown/yellow thing appeared the right/left lock screen shortcut animations stopped showing. And that thing is the exact size of the lock screen shortcut animation.
Also, those three burned in lock screen buttons, phone/unlock/messaging aren't really burn ins. When I try to press any of them in the bugged state when the screen is already unlocked, the dropdown menu activates. Also when I use dropdown menu myself, those 3 buttons are instantly gone without leaving a trace. And when the dropdown menu is activated, the yellowish corner translates from the background to the menu itself. Icons on the home screen in the background aren't yellow anymore, but icons in the dropdown menu are.
So, I'm completely at loss what to do here. I don't wanna use one of those burn in removal apps to mess my phone up, I don't have a warranty because I got it used like less than a month ago and everything was working fine. And I don't wanna take it to a repair shop because they'll just tell me the display is messed up.
There's just too much coincidence here for me to believe it's a classic case of display burn in.
Why wouldn't lock screen shortcut animations show up anymore if that was the case? Even on the left side which is completely fine. And it just appeared out of nowhere when I used one of those shortcuts. As if animation is stuck in there.
Sorry for the wall of text, but wanted to explain it in detail as I couldn't find anything similar anywhere else. <.<

I'm not familiar with burn-ins, but since it's a used phone the probability of the screen being messed up is high.
If it really is a software glitch, the only option would be to flash a different rom. If it continues, flash a stock rom via Odin. If the problem still persists, then it's most probably a hardware issue.
Remember, the flashes have to be clean flashes. As clean as possible. Dirty flashes won't help, especially when trying to find the root of a problem.

I've had it for nearly a month now and I didn't have a single issue.
As I've said, it's probably not a burn in because it just appeared like that due to one animation.
And since it's also there when I boot into recovery I don't think flashing a new ROM would help.

Is this gradient (around the icon) visible to naked eye? This is really nasty Just a guesswork: this could be one of failure modes for amoled. I have 8 weird rectangles burned in over the whole screen and really don't know where they came from.
Check this: http://forum.xda-developers.com/showthread.php?t=2603039 evidently even light from outside can burn in your screen.

Yea, it's visible.
That's the far right shortcut on the dock.
But the weird thing is that it just disappears if I try to click it.
Same goes for the lock screen shortcuts as I've said already, that's why I'm not sure it's a regular case of screen burn.
And when I pull down the dropdown menu, the color of the desktop goes back to normal, but dropdown menu icons in the bottom right turn yellowish, as if the tint translated to the screen that's being used at that moment.
After I realized that I tried to mess around with color saturation and brightness.
Changing brightness had no effect, lowering it would just make that corner darker, but as I dropped down color saturation on all of the RGB components more and more it became less and less noticable.
But the buggy lock screen shortcuts still puzzle me. They remain on the desktop after I unlock the phone, but are instantly gone as soon as I click them.
If it wasn't for that, I'd be pretty sure the screen broke because of bad build quality. I read about the display having too much pressure put on it, somewhat of a design flaw.
Gonna try that burn in app, what's the worst thing that could happen to a broken display. <.<

MuF123 said:
Does it disappear if you press and hold without actually doing something? Make a screenshot and display the image fullscreen as if it was lockscreen, will it happen again? While showing the screenshot, press and hold on the icon, any change?
Does all of the gradient disappear or just the icon burn in?
Click to expand...
Click to collapse
If I hold it, it actually works (eg taking me to messages or phone menu as if the screen was locked). It doesn't appear on screenshot, only after I unlock the phone. That's what's puzzling me, it's not actually burned in, it looks like an issue with the display when I change screens (from locked to unlocked or switching from desktop to broswer like in that screenshot with the burned in icon, as soon as I click it it also disappears, same as shortcuts).
And gradient gradually disappears as I lower the color saturation. Disappears fully at around 30% for all RGB components. But brightness is way too low then.

I get your point, like I'm leaning towards display issue but not a classic one but a weird one because it has issues with switching screens.
Idk, I'm gonna roll with this for a couple more days, if it gets worse it's definitely the display.

Just out curiosity - maybe you could make a video how this behaves

Maybe tomorrow if I find a half-decent camera.

Actually, I made a screencast.

As you can see, after I unlock the screen, all three shortcuts are burned in.
When I press the burned in unlock icon it just briefly opens the dropdown menu (it wasn't me opening it at that point, when I clicked the lock screen icon in the middle)
Yellow tint in the bottom can't be seen on the video.

G4 Digitizer problem?

I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.

Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.

I had a similar problem and was able to send it in under warranty and get a replacement phone

G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
