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.

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.

Touch Screen Unrsponsive after pocket time

My touch screen is unresponsive after I pull my streak out of my pocket.
After a minute or so it start working again.
When I first received it I did not have this issue.
I have flashed DJ_Steve's rom.
Has anyone else had this issue?
Should I send it back to Dell?

just saw your post after posted my one.
http://forum.xda-developers.com/showthread.php?t=876931
did u try in landscape mode?

So when I pull my streak out of my pocket it is on the lock screen, which for me is always landscape.
And with the screen unresponsive I can't unlock it.
To add a little more detail, sometimes the screen is only partly unresponsive. e.g. I can sometimes partly move the sound drag button, or the unlock button, but not fully.

I have had this issue after flashing 1.4.6, my streak is in landscape. I used dell 1.6 before that with no issue.
I have been using no lock off the market, when at home to by pass the problem, however the screen can still be unresponsive but only parts of it, for example one row of apps on the home screen can be pressed but others cannot.

Have you guys tried to do a screen calibration that worked for my streak 2.2 Dell bug fix version

It's not just you guys, I have this problem as well. I miss atleast 5 calls a day because I can't get it to slide to answer the phone call. As far as the home screen from pulling out of the pocket, I have found the pattern unlock to work the best with no problems. If I get a phone call, I try pressing the go back button on the capacitive screen and turn it to landscape and it seems to work. A pain...but I guess running a custom ROM has to come with a little sacrifice. I'll live though.

Doing the screen recalabrate worked.
That so does not make scene but it appears to have fixed my problem.
Thanks

No prob man

I have found that doing a long press on the power button to bring up the power of menu, then going back to home screen makes it all responsive again. Not a fix but lets me unlock with out having to wait for a minute or so.

I've had a similar problem before too when I first got the streak! Try keeping it in your pocket facing out and away from your leg instead of toward...
Also - maybe the type of material a person wears might affect it. I noticed this problem occurred more in my jeans facing my leg than in my suit pants facing out.

Mine's been doing this since I went to 2.2
Evidently the update made the screen more temperature sensitive or less, depends on how you look at it. I noticed that if I had the phone in my pocket facing my body, it was unresponsive until the screen cooled. Then it responded again. If I put my phone in pocket facing away from body, no issues. I also noticed it was unresponsive after I was on the phone talking ( the heat from my cheek?).
Have not found a resolution to this other than to keep the screen "cool" at all times so it would respond to the warmth of my fingers.
Just another bug in the 2.2 update it seems, so until Dell does something about it, Punk'd by Dell.

+1. I started putting it in my pocket screen out a few days ago (whether jeans pocket or inside jacket pocket), and it hasn't happened once since. When I do forget and put it in my pocket facing in, it's a 50/50 chance it will happen.
It seems as though constant contact with skin (through a thin layer of cloth) desensitizes the capacitive screen somehow, even (or only?) when the screen is off. Strange that the issue never occurred on Donut. (I'm on DJ Steve's Froyo 1.5.1 now.)
I hadn't thought about temperature as a possibility, and I doubt that's all there is to it. Anyone live in an extremely warm climate who has had trouble with screen sensitivity in other circumstances?

This can be greatly reduced by the way you carry it in your pocket... I'd much rather have it facing inward - but then the sticky unlock acts up. Facing outward it rarely happens.
I don't think anyone noticed this on donut because you only had to press the menu key to unlock... not use the screen. Question is, was this happening on 2.1?

I will try that for a few days, I had noticed that it did not happen if left the phone on the side or on my desk all day.

I always used a pattern unlock on Donut, not the Menu key, and this never once happened in over a month of daily use. Day one after installing Froyo I had to stop using the pattern unlock because it was driving me nuts trying to unlock the thing after taking it out of my pocket. Of course, any unlock I tried was impossible with this issue, and the only thing that really worked was just waiting for it to start working again.
No idea about 2.1, I only had it installed for about an hour.

i solved putting the streak in pockets with the screen towards the ouside of the pocket, and not facing the leg

+1million to all of this.
This was driving me nuts, thought I was the only one, exchanged the streak once already because of it.
Just had my coworker the cubicle across from mine try putting his streak in his pocket for 15 minutes, pulled it out, SHAZAM, touch screen didnt work for a few minutes.
Verified here on 3 streaks. 1 on 1.6 and 2 on 2.2 all have the same issue. 1.6 unlocks, but then nothing works until you mess with the facebook app, or another scrolling app, then everything works again.

did anyone happen to report this to dell? I think we might start to have a case here.

Another one with this problem. Noticed it yesterday. Screen facing in. Will try to face outwards next time in a warm building with carrying in pocket.
Same thing here though. Cant move the unlock but can slide the sound just a little bit. Funny ****

[Q] MyTouch 4G no touch on car cradle???

Very strange: when I put my MyTouch 4G in my car cradle (it's a generic one: http://www.officedepot.ca/a/products/494874/Gilsson-Universal-Windshield-Mount-Black/) the screen generally will not respond to touch making it essentially impossible to use.
I did notice that if I cover the back camera with my finger, the screen does respond to touch, even after I remove my finger. But then other strangeness occurs like it never times out to sleep mode and if I force it to sleep by pressing the top button, when I press the button again there is no lock screen and I need to cover the camera again to make it recognize touches.
I actually had a similar issue with my last phone (an Acer Liquid E) although using a hack to increase the touch sensitivity seemed to fix it on that phone.
I don't understand what is it about being put on a cradle that makes the phone behave this way. I have checked that the arms of the cradle aren't pressing any of the buttons and, in fact, just resting the phone in the cradle with the arms extended beyond the width of the phone does the same thing.
Anyone know what's going on?
Thanks!

probably time to return the cradle haha. but seriously speaking that just sounds super weird. especially the part where you say if you cover the camera the touch screen works. haha.

Does your cradle provide power ti the phone through use port? Generally this happens when there is voltage going to the phone that is interfering with the touch screeb, like using a generic charger.

I've seen this. It was caused by the cradle pressing in on the volume control. Adjust your phone on the cradle so the volume isn't touched and see if that solves it for you.
Sent from my HTC Glacier using XDA App

No the cradle doesn't supply power it's just a generic holder. I did check that the arms aren't pressing any buttons as that's the first thing I suspected. Even with the arms open so that there is a space between them and the sides of the phone, so long as the phone is resting on the cradle (just by gravity) this happens.
The fact that covering the camera temporarily seems to fix it is also really strange. I almost started believing the phone can detect the dash of the car through the camera and shuts itself off so you don't play with it while driving. But that seems a little far fetched.

I've had the same behavior with my generic car dock as well. It's very sporadic (maybe once a week), and I can't figure out the cause. But for my $10 it's good enough until there's an official dock that's custom fit.

So it's even weirder than I thought. Turns out this doesn't only happen with the car cradle, but also sometimes when the phone is lying on its back. Tends to be more likely on a soft surface like my couch or a carpet, but it's also happened on my work desk. In these cases slightly repositioning the phone seems to fix it. Also, it doesn't seem to happen if a charging cable is plugged in, so at least that should be a workaround for car use. It happens when waking from sleep. Once the touch input is responsive, it remains so regardless of what position the phone is put in until the phone goes to sleep.
I put up a video to demonstrate:
http://www.youtube.com/watch?v=9NX_3uds_Ek
The other thing I noticed is a purple light that comes on underneath the touchpad when its pressed. It's not really visible by eye but for some reason the camera really picks it up... Is that the pad's touch sensor?

[Q] G2 "ghost clicks" screen sensitivity

Has anyone noticed that their screen is picking up "clicks" without actually touching the screen?
on occassion my screen will detect a button click even if i haven't actually touched the screen. It's starting to get annoying, but I don't know if that's just the way the phone is, or if i'm too used to a capacitive screen rather than a heat sensitive one.

i had this happen a few times. not enough to bother me that much. it happens sometimes when my finger is hovering really close to the screen, like i'm getting ready to press on it but not yet because i'm still reading whatever it is on the screen, and then it ends up clicking it anyway. i think its happened a total of 3 times for me. 2 other times though, i've had the screen do double taps when i was just swiping around. trying to scroll up and down on a webpage and it registered as zooming in. i did do some zooming in and out a few seconds prior so i think for some reason it was "stuck" on double tap mode or something. had to switch the screen off and on to fix it.

yea it does the same thing for me as well. I sometimes go to press a letter and the letter gets pressed twice. it's really annoying. i'm hoping that if i buy a screen protector it will get better but i'm betting that I'm gonna have to battle with LG's terrible customer service.

Never happened to me. The screen (as with every other smartphone I have had) doesn't react unless I'm actually clicking. Even if I touch the screen with the SLIGHTEST touch I can do, it doesn't react. Which is good, no problem reacting when I actually click.
I guess it might have something to do with my fingers being hard as metal due to guitar playing or something.

On mine it seems to get worse as the screen gets oily. If it starts to wig out, I wipe down the screen and that usually solves the problem for a couple days.

When my screen gets overly sensitive i turn the screen on and off again. Usually fixes it.

Maybe i'm just crazy, but when i spend this much on a phone I shouldn't have to turn the screen on and off constantly to get it to work.
Hopefully LG realizes this is a problem and rushes out an update...

it happened to me... not only that the screen freezzes from the ghost clicks... the clicks are on middle of the screen staying... for example by playing Plants vs Zombies 2... the screen doesn't react at all.
I think that has something to do with the "smart-stay" or with the screen time-limit.
... plus of that... the phone gets really hot at that time.
any solutions?... or back to guarantee?
Greets.

Never happened to me, however I know exactly what you're talking about from using cheap Chinese tablets. Therefore I suggest getting it fixed or exchanged.

Same here, works this way, slightest touch wont react, actual press would.

i make my phone factory restore but the same problem appear..

automatic screen shut off

So I've browsed around and there are plenty of screen issues, but I haven't seen the one I'm experiencing nor have I seen a solution. When I press the power button my screen comes on and turns off right away. Sometimes a few seconds after I hit the power button sometimes even longer. Most times I won't even be able to put in my security pin to unlock the phone. I see people saying Verizon will do an update soon but that isn't good enough considering I can't use the phone. I did find a loop hole to this problem. Quick start the camera with the volume down button then press the home button after the camera loads and it won't shut off by itself. I thought I'd post this method up for others having this frustration.
If this particular problem has been discussed and beaten to death then the mods can close the thread.
I've got a YouTube link but I don't have 10 posts to show you. Search for user name "vfreeza" and it is the only video I've uploaded. You'll see my first time turning the screen on was using the quick camera method and the times after is with just the power button. The screen turns off without even my hand touching the phone.

don't cover the sensor on the upper left hand side

Yup I read that too. My fingers rest at the corners of the phone and I've tried the not cover sensor thing as well, makes no difference.

Wish I could disable the sensor. I hate this problem

Just a quick update. I bought a Diztronic tpu case and the moment I put it on all the problems went away. Screen acted nornal and knock works. My guess is without the case my hand is making some kind of connection it shouldn't be when I'm holding it without a case.

Did your old case hug the bezels tight? because it tends to mess with the digitizer perhaps the incipio feather case? or a plastic case of some sort? just curious im pretty sure that was your problem cause if you barely press on the screen youll notice waves in the lcd screen and since the bezels are so small on this device some cases can do that.

My phone has that very problem and it's driving me insane.. i love this phone, but it truly is a hassel to use it after its been idle for awhile.. or at night... hands no where near the sensor or anything, it could be laying straight up or down n itll still have that problem.. thanks for reading.
I normally just wipe the sensor area, n it magically starts working again.. n i don't touch it, n the problem comes back after awhile....
Also naked phone besides screen protector, but it's not covering up the sensor.

My phone does the same thing. It's so ****ing annoying.
