Calibration Issue

This is to get an idea about Touchscreen calibration issue with nexus one. I am trying to figure out if those of us who have faced this problem need to get replacement or just wait for software update.

Calibration of the battery or the touchscreen?... Very vague post... Give us the issues.

Touch Screen calibration. The lower 3/4 part of the screen starts acting crazy and registers touch below what you are touching. Needs a soft-reset; solves the issue temporarily.

Used to experience them semi-regularly. Seldom after switching to custom ROMs; both Cyanogen's and Modaco's Desire seem to have lessened the problem somewhat, though I can't imagine why as I don't think either developer poked around with the drivers or anything. And since I've been on custom ROMs for quite a while now, I'm certain it's not a placebo effect. I simply very rarely experience the problem anymore.

I too rarely experience this anymore after switching to Desire.
Also, soft-reset is not necessary. Turn the screen off for 3 seconds.

Damn it. It happen to me today again. I was browsing my email with one finger on the screen in the middle flipping through. Then all of sudden the phone kept vibrating as if I was touching the icons below. Then the search box pop up, a voice search came up and a task screen as if pressed those buttons!! I should have recorded it. Anyway I put the phone to sleep and wake it again and all is well for now. Anyone think this is a hardware problem???

never have had this happen, only thing i have noticed is when another part of my hand is touching the edge of the screen..

I talked with Google customer service today. She acknowledged that it is fairly common issue and insisted that it is not a hardware issue and even her phone has the same behavior. Whatever it is, they will cover it under warranty. So, i will wait for a month and if problem is unsolved, I will ask for replacement.

My other hand is not even on the phone. I'm only using one finger!

The ONLY calibration issue I have seen is when I am on my BT Hands free in the truck and go to hit the Mute button, it registers and presses the 0 (zero) key instead.
Hitting power (to turn off the screen) and turning it back on again (after a 2-3 second pause) fixes it...
Annoying, but not unusable...

My point was, I am having calibration issues. I stated my case, stated my opinion and moved on. Responses like these are useless and need to be purged.

As in you take it simple. You spent money on the phone and it has problems like those, you making seem normal for a phone that cost 500 plus. Almost like your giving permission to other manufactures that says its okay to have these problems.

I don't see why being $500+ should matter. FYI, the price range this handset falls into is the typical, NORMAL price being not subsidized to a network.

Kool then. Lets just hope this is a software issue. Because of Google silence on the matter, I cannot decide whether or not to return or swap the phone. Mainly because I don't know for a fact if its software and my 14days ends this Thursday

Maybe its a app installed causing the issue...

maybe its a design issue, arn't the antennas down in that part of the phone? If it happens with the desire ROMs too?
If it was easy to fix surely it would be fixed by now as its quite widely reported

Thats what I believed until I saw someone here said they were having touchscreen problems before but not anymore on a leak rom. So now I'm half sided in what to believe.

What makes you a genius, maybe we all have a app that causes our **** to go buggy when Its open or something... could easily be the dealio.... I don't have the problem so I don't care, but I know apps can make things very buggy....
I doubt it is a app, but it could be, and others that flashed roms that don't have the problem anymore well, maybe the new rom and app aren't conflicting, just a guess....

[Q] Droid X orientation

so... ya... my phone's orientation's not working right now.
so when i use navi, it's still in port. mode rather than land. mode
i have rooted dx 2.2 and it's just not working since this monday.
somebody help me out please!

That's funny you mention that. I noticed that my X is VERY sensitive and will flip to landscape if I slightly move.

Check to see that your settings are right.
settings>display>auto-rotate screen. Check this and you'll rotate, unless your phone is broken.

I can't confirm this works. I've done it with my phone and I can't say there is a difference but mine don't flips to landscape that easy but I did notice since the 2.2 OTA update it does change much easier than before. Anyway try to recalibrate the compass and see if that doesn't help your issue. Settings/location & Security

Touch screen w/o touching?

I've noticed that on my NS, I don't have to actually touch the screen to tap keys. I can keep my finger slightly hovering over the glass and it still recognizes my input. Sometimes it actually causes me to mistype at a higher rate than other phones.
Are you guys seeing this too?

Glad to see I'm not the only one who's experienced this....I thought I was going crazy. It's sporadic at best, but when it happens it is annoying. I can't say for sure what causes it, but I'd love to hear other people's opinions.

I've been getting this as well.

same here. Guess they have the capacitance set a bit too high.....

yup, me too. infact. my home button gets phatom long pressed and the light is off on it...have to power it off/ turn the screen off and on muliple times. that insanity has occured about 4 times thought.

Thanks for the replies. I went back into Best Buy and tried their demo phone. So either it's supposed to be this way or they messed up a whole batch of phones. I wish I could remember whether the vibrant did this or not, but it's not standing out.

Sometimes touchscreen nonresponsive too. This is not relating to partial outer border touching either.

I believe Engadget did mention did this during their review @ http://www.engadget.com/2010/12/10/nexus-s-review/.
Their exact quote: "One other thing of note -- we noticed a few missed or latent presses on the touchscreen which occasionally led to stuttery behavior or an opened item that we didn't mean to tap. It's hard to say if this was a software or hardware issue (and we know that sometimes Android devices can be particularly finicky when syncing). It wasn't a deal-breaker by any means, but we saw the issue rear its head a handful of times, and felt it was worth mentioning."

it's nothing ,, the Samsung galaxy S does that too D:

that happens due to the static on your finger.

Hi
I opened a thread (http://forum.xda-developers.com/showthread.php?t=879872) because I definitely have a problem on the back capacitive button, just wondering how many people are affected?
In fact I have seen this in four devices now, it looks that there is a batch of defective Nexus S phones out there affected by this problem?

It's normal. My Nexus One is like that too. It's magic.

So, it is normal to have un-responsive back button after some times?
Damn ... this is bad. I hope I can cope with it. I really hate hardware problem.
And still could not understand why Google cannot fix it.
Last time from HTC ...
And now from Samsung ...

There's a thread for the back button, that's a real issue. Some people have the Back button issue, some the Home button issue. Both of those buttons are on the outer edge of the phone, so something may be messed up when the phone was being assembled.

[Q] Misbehaving N1

I got my AMOLED N1 back in Feb 2010.
Unlocked bootloader, rooted 2.2.1.
The problem which existed from day one but showing much more often these days, is that after running an app (e.g. Market) the touch screen misbehave. It either does not register the touch, or maps the touch about an inch lower from where it should be. The phone has plenty of free memory (internal).
The problem is more prominent since the 2.2.1 update (but I am not sure it's related).
Does anybody else experiencing this?
TIA

Most people!
There is no solution other than the temporary fix of turning the screen off and then on again.

Yes.
I'm getting really frustrated with the N1 due to the ****ty touch screen.
I had a play with my brother's Nexus S.... SO much nicer and smoother. The touchscreen on the N1 is abysmal and shocking!
I've also noticed "freezes" in the sense that the display won't come up - only the touch screen buttons light up and then slowly fade off.... only way to recover is to pull out the battery. Really annoying.

Thanks DirkGently1, itay1,
Is there anything that can be done to fix this? e.g. replace a part (whether under warranty or not)?
It is actually becoming hard to even use the N1 as a phone or for text..

There's always the option of selling the phone while it's still worth something and buying something else!

oh well...

It sounds like yours is worse than the normal problem. My screen will only mess up once every few days, some people have gone months, some a few times a day.
But if your phone is unusable just get it replaced under warranty.

My first experience using Android was turning on my Nexus One and encountering this issue the very first time i had to use the screen! The device i have has had this problem in varying degrees since i got it. Very bad to start with, not so frequent after i sent it back for repair.
Take a look at the poll from my own thread about the issue...
http://forum.xda-developers.com/showthread.php?t=878477
Pretty commonplace problem, which along with the power buttons failing detracts from an otherwise great phone.

Blame HTC, I had this issue on my first N1 earlier last year. I would turn the screen off then turn it back on.

I find it behaves better when the screen is clean. Perhaps finger grease can confuse it... it might be *that* sensitive.

I flashed the frg83d update this morning and I've gone all day without the crazy screen thing and I'm loving it lol!
*knock on wood *
Hope it stays that way!

@DirkGently1:
I've added my vote
@itay1:
I was just about to write the same thing. It is much better after I've cleaned it (which I didn't for a while)
I am not using any screen cover. I never did. But maybe there is a cover that helps. Those of you who never suffered from this issue, do you use a screen cover/protector? which one?
Also, maybe the issue is intensified by how dry (or not) our fingers are compared to others..

Do you mean frg83g? frg83d did not help my case. sorry..

Yes I meant frg83g lol

KF Touchscreen Sensitivity Issues

Hello everyone,
I have been playing with my Kindle Fire, since I got it, and I am about ready to chuck it out the window, or just call Amazon for a new one, but I first wanted to see if you guys had any suggestions. My touchscreen is oversensitive. WAY oversensitive. Oversensitive to the point that if I have to type anything into the keybaord, I will be three letters in, the keyboard will close, and I will have to start over. So sensitive/messed up that when scrolling an article in landscape mode, using only my left hand to scroll, random links will click on the right side of the page. The opposite happens if I do it with my right hand. I like the device, and look forward to rooting it, and ICS goodness eventually, but I wanted to know I have a dud and need to return it, or if there is some hidden setting somewhere or what. I am open to trying anything. Side note: I also own a thunderbolt, and find its touchscreen too sensitive, but nowhere NEAR the KF. I am making sure to make deliberate presses and swypes, and trying to make sure no extraneous part of my hand interferes at all. (sometimes even using one hand to poke at the keyboard with the device sitting on the table will still produce the problems.)
Thanks for the help!
Brock

Hey Brock!
I've noticed that my screen is a little more sensitive than my epic 4g but not to the extreme you are talking about.
Perhaps your screen is bugged or something try calling amazon and see what they say.
Also as a side note try rubbing your hands over the screen smudge it up pretty good. Does that make a difference? I know it will look ugly but maybe there was a film or something on the screen. Just to test
*forgive any grammar or spelling mistakes I injured my right hand and it is hard to type with bandages *

Hi
I have a bunch of problems too. Mine is sensitive, and its sometimes a problem not overscroll, but yours seem to be extreme.
As a way out, if you have time drop by a BestB** and try it there, if yours is the same, not to much left to do....

I've been using mine all day and I don't even need to touch the screen. If I get my finger really close to the screen it reads as a touch. I'd say that's a tad too sensitive.

They are all like that. Its because the touch screen is capacitive. My Screen at work does that.

I'm having the opposite problem...I'm finding the touchscreen not sensitive enough....

Same here, I feel like I have to push the screen really hard to get it to register. I hit the screen lightly and it does not register my touch. I'm used to my EVO 4g, maybe it is just a lot more sensitive than the fire.

Same here, but it's not as simple as it not registering the touch. Most times the button will animate to show I've touched it but nothing happens. It happens most often with the back button, but happens in the browser and some other apps occasionally. I've had some luck with slower more deliberate taps, but it seems like a software bug to me.

I was using my mom's so I could teach her how to use it, and see if I wanted one. Her was also not sensitive enough many times. It wasn't just that I am used to my Droid 2 because my mom who never used a touch screen before had the same issues. Sometimes it would take 3 or 4 taps to make it work. I just thought it was a bug that would be fixed. It was minor. I ordered my one, so on Tuesday I will see how mine is.
OP I say contact tech support immediately.

My screen is fine, the only problem I'm having is the menu gets pressed, it shows that it was pressed but nothing happens

The two kindle fires I've used have the same touchscreen issue: there is a jerk (along the longest direction of the screen) on touch down. Once the finger is down the reported position is fairly stable, but the initial touch down needs to be smoothed out (or the first few samples from the touch screen should be thrown out).
This causes most of the issues I've seen on mine, where pressing buttons is either inaccurate or they go down and come up without activating (because the touchscreen reported a touch down inside the button and then jerked out of the button area and reported a touch up).
I've spent way too much time on touchscreen drivers (way too much!) and this is a fairly common electrical issue, and the software workaround is fairly straightforward to implement in the kernel. It's surprising that Amazon shipped the device like this (as well as various SGX drivers issues on some apps), especially as every review mentioned it as an issue!
Anyway, once we can build and flash kernels reliably I'm sure we can fix most of the touchscreen issues.

My kindle too !!!
Because of this, I'm getting very stressed ㅠㅠ
It's a matter of the touch panel... would be fixed by software?
If this is not possible... Then I'll be selling the Kindle

I downloaded an app called ILITEK Touch Utility which appears to have made my touchscreen work better. It is in the Google Market.

I'll have to try that out, would be nice to tweak it some Thanks!

mine is not too sensitive, sometimes i have to press multiple times for it to register

Bumping this thread, because this issue is annoying the hell out of me. Those having the touchscreen not being sensitive enough, it's the same issue as those finding it too sensitive. The problem in reality is that it's ridiculously sensitive, and as your finger presses down on the screen, it's sometimes reading that as an attempt to swipe/scroll rather than a tap/press, which is why you see things light up still, but not launch.
This is frustrating me more and more as time goes on. I've tried this, which I can tell adjusts some of these settings but doesn't really make much difference for the problem. I've also tried this, which didn't help any after calibration.
Some people have speculated (or confirmed, for all I know) that this can be adjusted via the kernel. Does anybody know of anything that might help with this? It's so sensitive it's making me want to avoid the damned thing. I'm about ready to restore the stock ROM and give it to my sister as an early Christmas present.

The awesomeness that is Hashcode is working on 3.0 kernel over in the dev section. The kernel is still a work in progress and has come a long way. At the end he is apparantly going to update the touchscreen driver. I hope that will fix any said issues.
