Nexus One Screen Accuracy Issues

Hi
I purchased my AT&T 3G compatible Nexus One the first day it went on sale, I just updated to Froyo and I notice that sometimes my screen fails to respond. I have to power on and off my screen for the issue to go away. Some examples are when im typing and I hit and key and it chooses another one or i'm trying to scroll on the menu and even if im picking something from the top the phone highlights the menu icon at the bottom. Are this issue just with my phone? has anybody been able to fix this?, If i call HTC support and they send me and new phone will it have the same issues?
Please guys let me know... this is driving me crazy

the screen on this phone blows... plain and simple... you will just have to get used to it...

do you think i should get rid of it?

Hi,
Don't get rid of the phone. You don't have to reboot, just lock the screen by pressing the power button, then unlock it. I've had it a couple of times but it goes away when I do that.

Also, be aware that it's very sensitive to any part of your hand that might be leaning over the edge of the screen, or hovering over the touch buttons. For example if my finger is hovering over the home button but not touching it, and then I touch somewhere higher up on the screen, it may respond as if I had pressed menu.

So...are you saying we are holding the phone the wrong way? Lol.

the nexus has this issue with the screen. its not a big deal, just lock the screen and unlock it, it fixes the problem. its some kind of mis calibration issue. yeah it sucks, but not the end of the world. only takes 2 seconds to fix it.

Heehee. I guess Android isn't immune to that either. Nor is the EVO or Droid Incredible (not identical problems but they're still there). I think it's inevitable that as we try and jam more and more "magic" into a single unit, things start to crosstalk in unpredictable ways and glitches emerge.
I have to say, the touch-sensitive buttons on Milestone & N1 really throw off people who haven't used them before. If I pull up a picture or video and I'm showing it to someone, inevitably they clutch the phone with a finger on a touch button, and then I have to get them back into the app and explain what not to touch. That's one reason I'd rather have physical buttons such as on the Desire.

I have this touchscreen problem as well, and yes its a big deal for me! I spent $580.00 for this phone. This shouldnt be happening at all! I've tried all sorts of troubleshooting(deleting cache partition, updating to the latest froyo, restoring factory settings, tried without installing 3rd party softwares, etc..) before i finally came to the realization that this is a hardware issue. Ive tried narrowing down to possibly when and how it occurs, but you can't. It just happens when it happens. It's impossible to predict. When this problem occurs, watch closely to where the calibration is off. During the problem, the calibration is only off on the bottom half of the screen, more so close to the bottom right. The top part will work perfectly. You can test this out by swiping left to right or vice versa on the homescreen. This problem will also affect the Pinch-to-Zoom in Browser, and the ability to type correctly using the default keyboard or 3rd party's like Swype. I received an exchange thru HTC a couple days ago, and not only was this exact touchscreen issue prevalent in this unit, but also it suffered from the purplish screen tint. This issue seems to have existed since they first launched this phone, but for some reason there has been no fix for it. It's funny that the EVO received a software fix promptly after the issue was reported by many. Why not the N1?? Because it's hardware, that's why! Feature wise, this phone is by far my best PDA, I mean I really love this phone, but $580.00 is too much for such an issue to exist. I'm hoping that there's only a number of bad batches floating around. I would say, if i receive 4 exchanges, all with the same exact issue, i may look into a class action. I definitely wouldn't want to be stuck with this problem after my year warranty is up!

I haven't had the 'crazy screen' thing since FRF85B, I assumed they'd fixed it.

I haven't had it since upgraded to Froyo too

not hardware problem
I encounter this problem a couple of times and I tested two things: useing trackball I ran touch sens app and tested the touch sensor, it was fine, second I killed all apps using a task man and it fixed the issue. I am on froyo.
Sent by my Nexus one.

I experienced this yesterday for the first time on FRF91 (unrooted Stock build). I couldn't press the "enter" button on stock keyboard. It just kept choosing Delete instead. Lock/unlock screen via power button sorted it.
So the problem is still there in latest build of FroYo (for me anyhow!)
Anyone else?

I've had this problem ever since I got my N1. Sometimes made me want to switch back to my iPhone! Makes it a lot harder for my son (2 1/2) to use the phone too.
Seems reports are mixed to whether froyo fixes it or not. But it gives me hope. I've been using CM5.0.8, holding out for their final release but this gives me a reason to try MCR.

I have upgraded to FroYo FRF91 but still see the same issue.
Sometimes I face with the calibration's flaw for the left bottom corner of the touch screen.
What a shame I have paid 750$ here for this phone. I really love it but this flaw screwed up all the pleasure.

i have two n1, one has this problem occasionally, the other one never. Both run same kernel, rom and apps
A quick lock and unlock fixes the problem

So it is a hardware issue? Maybe we can get htc to replace our phones.

Well looks like I still have this issue with frf91.

i think no one really knows. Would be a strange hardware issue which can be fixed by locking and unlocking.

HTC Hero CDMA Backlight

Has anyone ever had any issues with the backlight on the Hero?
Lately, sometimes, when I turn my phone on or something, it's as if there is no screen at all. It stays black, eventhough I know that the OS is running. I've even tried rebooting, taking out the battery, etc... I can tell it's booting normally because it does the little vibrate, and then vibrates once the OS is fully loaded, etc... cept, when this is occuring, I cannot see anyting on the screen. If I tilt it just right, I can JUST BARELY see the outline of a window or something (whatever is up on the screen at that time). Then after dealing with this issue for a couple of minutes, and rebooting a few times, it works itself out.
I'm thinking I'm starting to have some type of hardware failure, but really don't want that, because I'm due to upgrade to the EVO here in about a month and don't want a stupid replacement just so I can go buy a new phone a month later, ya know? Anyway, wondered if anyone has had the issue before and what, if anything, they may know to do to fix it.
Thanks guys!

Yes I get the same issue off and on. I think it has to do with CM6 and the brightness settings. Not sure though.

For some reason when I flash CM6 it sets the Automatically Adjust Backlight setting to be off. I figured it was just the nature of the rom, so everytime I flash a new one, I go and turn it on in Display settings.

No man, I'm saying, even when I first turn on my phone, I dont even see the white HTC screen. It's completely black, but vibrates like normal when I press the power button to initially turn it on. It's fukd I'm pretty sure. I can't see a thing on it, not even in recovery. It's completely black, but vibrates at the correct times it should vibrate (when I first press power button to turn on, when the rom initially boots up, etc...)
I'm thinking my hero is dead....
I only had a little less than a month to go before I could get an EVO too.... damn phone.

Have you done any damage to it? Sprint might replace it for free.

Nope, I didn't do anything to it... unfortunately, I'm stuck with CM6 installed on it, because I can't see it to be able to switch back to the stock ruu... LoL
so I hope they don't notice and then say, well, too bad, u'r screwed because u rooted u'r phone. But no, my phone is still immaculate except the 'End' key is chipping off (the paint). That's about it
I'm hoping maybe they'll let me just upgrade to the EVO since I'm due in about a month anyway. I doubt it, but even if they give me a replacement (a new one) then I'd be okay with that.

Welp, they ended up replacing my phone with a replacement (refurbed) Hero... I pretty sure this one is 99% new though, not a single problem aesthetically and it seems to be running froyo quite smoothly. It basically feels like a brand new phone (which according to Sprint Reps, there's an 80% chance of getting a new replacement and 20% chance of getting a used replacement). I'm thinking I'm in the 80% range
Very happy thus far... just my touch screen is a little quirky right now b/c I installed a clear screen protector and believe some of the moisture is interfering with touches... which has been getting better as the hours go on. So that's' good!
Thanks guys on the info.... It's just fine for getting me through until Sept. 15th so I can upgrade meself on the EVO!!!!
We shall see if it holds up until then
Take ya'lls and thanks for all the replies

You should get the epic instead. Lol

[Q] [Help] Touchscreen Becomes Unresponsive :/

Hey
I am currently running 2.1 on my Samsung Galaxy S the only thing ive done to it is root it, so its running the normal firmware and I'm waiting till the end of september ti get the official 2.2 before I look at flashing something custom onto it, anyway...
I have an odd problem with the phone where the touchscreen part of the phone will become unresponsive for no real reason, sometimes playing a game, sometimes just sending a text or browsing the market. My actuall hard buttons like the homescreen or volume control still work during this and the only way to make my phone un-freeze is to press my power button once to turn the screen blank, then press it again and slide to unlock the phone, then it works fine.
No clue how to fix this... anyone got any ideas?
Thanks in advance..

Sounds like hardware issue. Get it fixed

Thanks for the response (know it was a while ago)
I've had the phone 2 months now in a contract with T-Mobile UK through Carphone Warehouse... Does anyone know what my return rights are? Talking to them later just want to know where I stand when asking for a replacement.
Thanks

hello, i have same issue. Did you fix this problem?
Thanks

This comes really long after. But did anyone find out the reason for this?
I've got an Galaxy S that works fine most of the time. But from time to time the screen will become unresponsive. If I press power button to lock the screen and unlock it again, it goes away. So it seems that it is a software problem.
Another peculiarity is that the keys on the Samsung keyboard are very inaccurate to respond to touch from time to time. Sometimes it is just impossible to hit a letter in the mid row and pressing "s" can put "wz" on the screen.
I was thinking to just put CM on it anyway. But it will void the guarantee in case it is a hardware problem. So I want to make sure that it is software related.
Did anyone manage to fix this either by returning the phone or removing TouchWiz. I am not living in the same country as I bought the phone. So returning it for a checkup will take some effort.

For what ever it is worth
I took the phone to an unofficial service center that flashed the phone with a brand new Android 2.3.3 (the phone came with 2.3.5). A downgrade, which normally isn't a very good deal. But the dead areas on the screen are gone. The phone is much more responsive and the keyboard is not acting funny anymore.
So... if you are experiencing the same. Try getting rid of the TouchWiz before you start taking the phone apart.
Good luck!

I get it occasionally but I've grown to live with it, mine tends to be the kernel recently flashed devils for 4.0.3 but after fiddling with volts mine stops.

search button glich

Hey all, recently my search button randomly presses itself. No, I dont see the color flash or what ever you see when you press a button but at least 2 or 3 times a minuet it will act as if I have pressed the button and search will come up... Some sort of new glich? or is my phone going defective? What do you think?
ROM firefly 3.0 that i have been using since it came out, so like a month with NO problems what so ever. Reinstalled FF, still did it, will try a new flash, if that doesnt work will go to stock. and if that doesnt fix it I will get it warranty replaced.... but Im hoping its not hardware...
???

This happened to me! Try reflashing the kernel, or using a different one. Might help

I noticed that when my cappy has a fingerprint or smudge on the search key, it magically will press itself. I also had to modify my invisi-shield to not cover the touch buttons. It happens less now that its not on them, but it still happens.
It was happening over and over and I looked at it and theres a smudge, wipe it clean and viola! This was quite annoying when I was using a rom with the camera mod that redirects it to the search key. The camera was constantly opening, had to run the "fix" to revert it back.
Hope its just as easy as that for you, I was able to duplicate the problem on 3 cappys so far.

this could be a moisture issue. yank the battery and drop the phone in a bag of rice for a day see if that helps. if it still happens flash to stock if it still does it after that its a hardware issue and you should get a warranty replacement if thats an option.
a search would've answered this as i personally have answered this question a few times, also this is a question, for future knowledge those are posted in the Q&A section.

by that do you mean put it in a bad ontop of rice or literally stick it into a pile of rice ( wouldnt that get into the phone)? sorry for such a noob question.

Put the phone in the rice. None if it is small enough to get into the inner workings of the phone but it is AMAZING at soaking up all little bits of moisture.

Would be willing to bet it is a moisture issue. I have the same problem no mayer what rom I am using
Sent from my GT-I9000 using XDA App

Mine does this quite a lot as well. Most often when the phone is warm while charging. I've noticed holding it in a different position helps diffuse the problem as well. Must be a hardware defect. :-\

so are the chances good that the rice will take care of it? Strange, I never shower or use my phone in wet area's.....
I have squaretrade... do they swap it out or what is the precedure for getting a new phone from them if it doesnt work if you know by chance, if not, Ill just google it on the website

[Q] Samsung galaxy Note-Right hand corner of the screen is unresponsive.

Hi all.I bought my galaxy note almost 2 months back.This is my first android phone.I have used iPhone 4 before buying this beast.I must say its awesome.However lately i have started experiencing a little problem.I have noticed that at times while typing my note's screen( Right hand corner) became unresponsive. I had to press the screen a lot of times to actually type a single letter( it was the GO button actually.) After struggling with it for 5-6 minutes it started working fine.After a few days i experienced the same problem again.I took my handset to the service center but the screen was working fine then.
I face this problem sometimes . i noticed that after locking the screen and then unlocking it solves the problem for that moment.Is this a software problem or hardware.
I wasn't able to convince the service person that my device has the problem.How can i make him convince and get the handset replaced.
Any help would be Highly appreciated. (The problem area is actually the place on screen where application icon is situated.)

Is the problem there only when you charge it? Because, there are known issues with many smartphones where that is the case. If it is, then I am right there with you, and trying different chargers I heard will alleviate the issue.

No the problem is not when i charge the device.I face this problem very rarely but not when charging.I would like to mention that the charger provided with the device was very slightly bend on the charging end as if it was forcefully inserted in some device.Though it charges the device without any problem.

Sorry, don't know what else to say. Good luck though.

I have had the problem with the bottom right corner becoming unresponsive to screen taps .This usually happens when the phone is not in my hand but is lying on a soft surface such as a pillow. However the minute I pick it up in my hands, the problem goes away. Strange. I had my note replaced under warranty, only to find the problem re occur on the replacement phone after a few days.

I'm having the exact same problem and thinking of taking it back to the service point. However, could it be rom related?
I'm running LA4. GOing back to a backup of KK5 alleviates the problem.
Something else I've noticed is that when left on a surface the application
button rarely responds but as soon as I touch it on the sides it works and when Ialso plug the usb cable it also works flawlessly.

A friend of mine has the same issue, but it only occurs if the device is laying flat on a table which is odd, he plans to have yet another screen replacement but will probably wait a few months due to shoddy quality control.

I had this issue since the 1st day. It became worst during charging. Have tried every old and new rom with no luck. I though it was a screen issue where I even applied much pressure to the affected area hoping it would help but no luck.
But the issue went away after I flashed Abyss kernel 3.9 via cwm. Now the right bottom corner is as sensitive as the left bottom corner. You might wanna try a different kernel 1st before sending to the service center...

If I remember correctly one HTC phone had similar problem, screen was unresponsive when lying on table but as soon as u pick it up it worked fine. It had something to do with screen/digitizer not being grounded properly.

I got my handset replaced last Saturday, but i am facing the same problem with the new handset.Are you sure that by changing the kernel the problem will be solved.If yes then how can i change the kernel of the handset ?

Interesting, this is theme #1,500,000.

Definitely a hardware problem because when I took it to Samsung service centre, the first thing they did was to flash the phone firmware. Only when the problem persisted, a replacement was given.

shot in the dark here, do you have a case on your note? I was going nuts on the first few days with my note using a flip style case only to find the damn magnet was causing the touch response issues. Took the case off and haven't seen the problem since.

After further testing it seems in my case at least it was definitely a kernel issue with cf-root kernel la4. Replaced it with a different one and problem solved.

Same problem here, put it down and bottom right corner doesn't respond, pick it up, responds instantly like rest of screen. I thought I had some kind of insecure Note that needed to be held or something. Last few days it was really freakin me out to the point I was purposely putting it down and then pressing and pressing and pressing the back button...nothing...pick it up...works with one slight touch, I was like WTF? What the hell could cause that???
Somewhat relieved to see I'm not the only one with a clingy Note. I'm going to wait and hope ICS fixes the issue, if not I'll guess I'll have to learn how to flash.

Right-hand corner of death
Thank goodness I'm not the only one in the world with this problem.
I first observed the problem when i upgraded to LA1. I was loving the improved battery life like a puppy until i noticed the bottom right part of the touch screen was as dead when placed on a flat surface. It started working again after I had picked it up, making me wonder if it had a "Hey I'm being hand held" feature, but it would still trip out when i'd type an SMS or email.
Called the Samsung service center to ask about it. they said they've never heard of such a problem and that I should just bring the phone in for software downgrading since my Note was ok till I upgraded it. For them, it was a firmware problem so replacing it was not on their priority list.
I ended up downgrading myself to KJ3 (using odin) which works fine. Unfortunately, i no longer enjoy the improved battery life or one-handed keyboard config.
No choice now but wait for ICS and hope it works flawlessly.

This is definitely a problem with screen. I got mine replaced an hour ago and did the LCD test. The new one is working perfectly fine (with and without flip case).
Try the LCD test . *#0*#.If the test fails get the hand set replaced.

Outsyder,
What software version are you using?
Tried the screen test and mine works flawlessly on KJ3. Since I'm from southeast Asia, I don't have any other updates available except for LA1 which is buggy on my Note.
