[Q] TouchScreen problem - Nexus One Q&A, Help & Troubleshooting

Hello,
I am new to Nexus one coming from Iphone 3G. the phone is quite good but i experience a little problem.
When the phone is plugged in and is charging, the touch screen becomes very inaccurate. Typing on keyboard is impossible...etc, the only solution is to use the trackball. Everything is gone after unplugging it from the power cord.
Do you have any advice for solving this ?
Best Regards,

I've heard that if you press the power button to put the phone asleep and then press it again to wake the phone would reset the touchscreen

Is the phone getting hot while you are charging it?
I found that when it gets really hot that it can mess up the touchscreen a little.

Common problem, no fix for it. Just black out the screen, and the problem resets itself and goes away. Takes 1 second. It's a hardware issue.

i have same problem too....

sorry... wrong post

Thank you for your answer, i understand that plugged or hot can mess the touch screen. It's not "fixable", i will live with it.

I sent mine back 3 times and it is finally fixed. I have a perfect touch screen. Have not had san issue in over 2 weeks. Send back and leave note with your phone. As I said I would not except no for an answer.

Unrepsonsive screen after GPS navigation

When I use GPS navigation, after a while the screen becomes unresponsive, and the unit itself gets really hot. This happens both with the car dock and without, without car dock it just takes more time.
I contacted HTC's support and they arranged a phone swap. I'm wondering if I'm going to get in trouble with this, since my phone is rooted. I would like to understand if this is a real problem, or something due to the rooting process.
Anybody experiencing the same problem?
I have experienced the same thing with my phone when using GPS for awhile. To solve the unresponsiveness I just press the power button and press it again to unlock my phone and the screen starts to respond again.

I dont think it should be a problem with HTC if it is a genuine hardware problem and your phone wasnt treated poorly (dropped)

Segment of touchscreen on Milestone not working?

Hello,
I'm not really sure if anyone encountered this before..
Suddenly today in the morning, I notice my Milestone's touchscreen is acting up.
I can't reach the menu button at the bottom of the screen. It always chooses Phone or Web Browser button instead :/
I use search to get to Dev Tools and Pointer Locations, and I realize there's a segment, about 1 third of the touchscreen, in the middle, unresponsive to touch.
I tried cleaning the screen, clearing cache, rebooting, it made it work temporarily, but then it returned again. I changed to stock 2.1 SBF, still no change. And now, its stuck in this state, I can't get it to work even temporarily..
I really dont want to send it to Customer Service, is there anyway to solve this?
Thanks!

Same with me, i can't reach from menu in a bottom side to upper side, maybe 10mm dead space + 7mm right side from bottom side to upper side.
Please help me!!
Sorry my english is not good
It happen to me last 2 weeks while helping out a friend's Milestone. After i flashed a kernel, the whole screen is not working. Trying to flash back to stock ROM,custom ROM,etc but still the same.
By accident i press and hold both BACK key(the bottom left) and SEARCH key( bottom right) and ON the phone. I let go of the the two,BACK and SEARCH key after the phone is completely ON. To my surprise, it works!!! Until now the phone has no problem with the touchscreen.
I hope you guys can try this out or is it an coincidence,I don't know..

thanks but no fix it for my phone
I had the same problem sometime last year, which I eventually fixed by clearing cache partition and rebooting a bunch of times.
Unfortunately, the problem re-appeared today. So far, rebooting and clearing cache hasn't worked.
By any chance, have any of you installed the WiiMote Controller App? I was convinced that was what was doing it to my phone. (maybe not, as I never re-installed it though)
I'm about to flash the sbf file, but as Lesiroth said, that might not work
i believe u r having GHOST TOUCHSCREEN syndrome
my touchscreen sometime do not response to my touch
it just went berserk!
the notification bar keep sliding up and down
if im in the menu, it goes up and down too!
sometime i cant unlock the screen bcos it do not respon
however, some chinese users found that this could be due to ripped/ torn ribbon
just google it
it is widely reported too!
I just want to say that I have fixed my Droid's touchscreen problem (or maybe it will re-appear in another six months).
Anyway, I just set the screen brightness to max and screen timeout to 30min and let the battery drain. I took the battery out for a second and then charged the phone with the USB that came with the phone over the wall socket.
I think the USB wire is the culprit (I was using a BB one for a while).

my problem seemed to be disappeared after i soft reset n use stock rom
i tot launcher pro was the culprit but it is not
so i re-install LP n use for 1 day
d only problem i had was when i went for a jog, i tucked it on my waist (no in the pocket).
after that the screen stop working at all, i have to reboot by taking the battery a few time.
after 30 min or more, the problem was gone.
tis could be due to the stress applied to the screen when im joggin (as it it as "touched" while im jogging).
however, i removed beautiful widget n its addon too, dat could the source of the problem as well.
SOLUTION: soft reset, use stock rom / launcher for 1 day
if it still persist, it could a hardware problem

I am glad that you solved your problem. Unfortuntely the past week or so has been a really busy time for me, I could not focus on this problem. I will try your solution, although I still think it is a broken digitizer on my part.
maybe the problem is the digitizer..
try to change rom or wipe it first..
if the problem still persist i think its the digitizer..
use only the original charger..
OMFG that worked on my phone!!!

Its a common problem. I had the same. Unfortunately your touch screen is dying. Replace.

Welcome to the club, apparently some people fixed it by warming their phone, putting it in rice, or replacing their digitizer.
i have another kind of problem: sometimes the screen begins it's own life, like somebody quickly touching it (solves with on/off button).
And sometimes i touch it in some point, but it thinks, that i touch it in another.
Disappointing, but not annoying.
well it seems to be working fine now

Got the exact same problem, send it for repair. Apparently they found corrosion in my internals, though I really have no idea how liquid got in there. There is no spillage or any sort happen to my phone.
Oh well that means goodbye to my Milestone and back to stone age for awhile.
I had this same problem a week ago, and it happened all day long. It happened that my screen was wet (don't ask me how, I don't know), and now it's working just fine
Well if your touchscreen are not responding well to your touch, or if you feel that a ghost has been playing around on it (eg. "like somebody quickly touching it"), then it's a symptom that the touchscreen is faulty and it's time to replace the digitizer or buy a new phone
I faced the same problem sometime. In this case, reboot the phone may fix this problem.
If it doesn't work, I think you have to replace the touch screen.

Had one issue like this in 3 months, 1/5th from the top of the screen wouldn't respond anymore, no matter the program. The issue went away after rebooting the phone.
I am facing the ghost touch problem or the right side is not working at all. First time, it started on it's own but last night, while it was connected to the PC the nightmare began. I don't know what the heck should I do, because I don't have money to spend on new digitizer. Last time the problem was solved by letting the phone in a dry place (it wasn't dropped in water or so). I hope this time will work too... BTW, pressing the on/off button seems to fix the issues for ~3-4 seconds. Anyway, Moto sucks .

Are you sure this isn't the flex cable problem?
If it is the flex cable problem, where can be found to buy and replace? Because I am sure that is less expensive than replacing the whole digitizer.
I had the same problem, but it's more than a month that I recharge battery with a Samsung wall charger (700mAh power), it completely desappear.
One week ago I charged the battery with the USB cable and the problem reappear, desappearing only after a reboot.
It's NOT a flex problem for sure, our phone is very susceptible of current variations when charging. If the problem still remains after unplug and reboot, I suggest to try with another battery.

[Q] Screen's backlight flickering...

I bought an HTC Desire C on Cricket the other day and the touch screen didn't work in the middle of the phone. I went to exchange it and the new phone has been working flawlessly until I noticed something VERY annoying. When I press the power button or let the screen timeout, the blacklight flickers on for about half a second or so, and then goes off again. My girlfriend got the same phone and hers did not do the same thing. I don't know if it is a hardware or software issue but it annoys me so much. If anyone knows of a fix, it would be greatly appreciated.

touch screen sensitivity?

Anyone having touchscreen sensitivity issues? I'm having ghost swipes galore while trying to scroll up and down a page like Google now or Facebook. Try swiping left and right on the home screen. On mine it just started to not respond anymore after a couple of times. Even if I go to the multitasking page, I'll try and swept away each open app and it'll just start to not register. This is while not plugged in btw. I really love the phone otherwise and want to keep it but I'll have to return it if this is a common problem. Is this an issue with the phone or just me? If it is just mine then I'll just exchange it and hope I get a better one.
Actually it is much more prevalent while charging. I also forgot my Moto mod battery pack charges constantly and my cause grounding issues also. Let me know if it's just my phone y'all!
I had these issues initially, especially with the bottom of the screen and the back button, but after a couple reboots they're totally gone. Try a hard restart (hold the power button until it restarts). I use a turbopower mod so i don't think its that.
My charging cord doesn't work.I just bought 3 days ago and it will not turbo charge

after reboot initially it's better but then it returns after a few minutes. is it the same for you? does it return? anyone else having this problem because I'm trying to determine whether I should take this back or not and get it exchanged.
Problem was an isolated incident and I'm happy to announce that I exchanged the faulty phone for another and this one shares none of the problems said above. So in short, if you're having screen sensitivity problems, send/take your phone back for a new one.
It's flawless now! I freakin love this phone!
