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.

same here

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.

problem while talking on the phone

Does anyone have an issue with your cheek pushing buttons while you are on the phone? I am running liberated_aria and whenever i am on the phone, my screen does not shut off like other phones and I end up either hanging up on people or moving widgets and even adding widgets..
has anyone else noticed this? is there a fix for it?

Its happened to me once on an Aosp rom. Haven't had any problems after that though.

I haven't had any problems. The proximity sensor is on the top right of the phone, where the AT&T logo is. Try making a call, to voicemail or something, and then waving your finger over the sensor. Does it ever turn the display off? Could be a software bug I suppose, or just a faulty sensor.

if you use your left hand/ear its pretty easy to dodge the sensor, unfortunately.

I tried a call using my right hand and I dont have that problem. Only the left.. I guess Ill have to start making all my calls right handed.

It figures...
Us southpaws always get the short end of the stick. FWIW, I almost always hold my phone(s) left handed, and only rarely seem to have this problem. ( It might just be that I have a huge head, and big ears. )

Im a righty and sometimes when making calls i get a haptic vibration from my face touching the nav buttons i think, nothing happens though.

My girlfreind is having the same issues with her handset.
We found her an Aria about 2 weeks ago at Best Buy Mobile for $1. They are running some great special for non-iphone handsets. The Aria was giving her problems and we ended up exchanging it. The 2nd Aria also has the same issue. While on the phone, her cheek will press random buttons and even hang up. Sometimes she just feels vibration, sometimes its a number pad press, and sometimes she just hangs up all of a sudden.
It seems to be some sort of sensor issue. Does anyone have some insight as to how to fix it? It's kinda of a big deal if the phone function is impaired by having to hold it away from your face.
Thanks!

Other then making sure her head is covering the sensor, she canlock the phone in mid call and it should stop her phone from registering her cheek while on a call

Huh. I'm a righty, but I talk left hand / left ear, and I never have any problems. Do you tilt the phone in some strange way?

Thats a good idea. Thanks.

This issue is really pissing me off. I love this phone a lot but the proximity sensor is not working as it should, atleast with my head shape.
Seems almost in every other call I make/receive my cheek contacts the screen and pushes something because the proximity sensor is not detecting me head.
I've tried locking the phone with the button on top of the phone but that does not work, it's only temporary until the proximity kicks back in.
And, the funny thing is, when I try to "test" it out or replicate the situation I can never seem to do it again! It always happens unexpectedly.

I'm in the same boat with this too, but it's a hit or miss thing and really could be much worse.

i can't say i've ever run into this specific problem. i've actually been impressed with how well the sensor has been working.
i would agree with the previous poster who suggested to lock the screen once the call is active. make your call then tap the power button to lock the screen and that should help you avoid the issue.

[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.

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?

Capacitive buttons pushing themselves

My 3 Capacitive buttons keep pushing themselves. While i type a message or read my email or i do anything my apps start to go back like someone is pressing the back button or the home button. I noticed that this happens if i leave the phone in a warm place. is there anything i can do about this?
thanks

Try to clean your screen with dry cloth. Sometime wet surface can active touchscreen display. I also notice that if I use non original power supply can make my streak like crazy. My streak become runing some activity again and again and again altought I didn't touch anything.

Oily screen does this give it a good wipe.it happened to me after having chips.if I would raise my finger 1cm away from a key on keyboard it would press it without me touching the keyboard.

Your phone seems to be haunted. (creepy)

They definately don't like heat, I been in the upper 90's/low 100's here lately and if I'm out in the heat very long with the phone in my pocket, it starts freaking out and just starts a constant reboot cycle until I get somewhere cool. I went to an area fleamarket today and it did it again.

Mine does something similar when plugged into a non dell usb charger, read it head to do with interference affecting the capacitive screen. not sure if you we're charging at the time.

So that would explain why my Streak bootlooped when I was out and about the other day.

Had to leave the Streak in the car today(turned off and not in direct sunlight) while I had jury duty, when I got out and turned it on, it went into a reboot loop until I got the AC going and sit it in front of the vent for a few minutes. Everything is fine since.

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.
