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...

Eh? This makes no sense...
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....

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 ...
*Still waiting Nexus S from UK*

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.

Woah! Capacitive Buttons!

Anyone notice that when you touch a capacitive button that the actual light turns off behind that single one? I'm running CM7 B25 Nightly- haven't tested it from stock. I just thought that this was awesome and also hard to notice. Or, eve, maybe my phone is junk and broken.

Does not happen on Stock, Bionix(curent ROM), CM7alpha2, or Modaco r3 as far as I remember. I can restore backups of each of those ROMs to confirm. Lights stay solid as can be.
However, if you like the "feature," I wouldn't consider the phone defective.
EDIT: I am wrong. They do, but it's exceptionally subtle and I had to jab the phone next to my eye to see it. Very cool, in retrospect.

they all do that... Nice touch to the phone I think. Little barely noticable things like that are neat....

I'm running the same build and mine do this as well; I think they probably did on stock firmware too. Kind of cool, but mostly goes unnoticed for obvious reasons.

If they can be controlled independently, than I think we have a prospect of notification LED's. These would work great.

I've run stock since the day I bought it, and on my phone the capacitative buttons have always responded to a press by shutting off the light behind the button activated.

OH SHI--it's very subtle. I just grabbed my phone and stuck it next to my eyeball to see the lights. You're right, they do go off for the splittest of second and you'd really have to be looking in order to see it.
Sorry @OP for misinforming.

Yes, they do this. This is also why they go black for upwards 10 seconds at a time on their own with the common phantom home/back button issue many are experiencing.

Mine are doing that. I'm stock.

Wow cool, just noticed it. Stock and root online.

Capacity buttons turning off per press is cool.
I also think one of the coolest things about the Nex S (and of Gingerbread) is the two finger slide show you can perform in the Gallery albums. Just place two fingers on any album and slide them apart. Neat effect.

That's a feature of stock Android 2.2 Gallery app. That was there on the Nexus One.

This is a cool feature. Like wesbalmer says, it could lead to replacing the NOLED app for notifications! If I hold any of these buttons the light also stays off until I let go.
Not many people will notice this feature coz when you press a capacitive button your finger covers it

Human 2.0; now with transparent fingers!

This feature was already available on sgs froyo 2.2... Just noticed it now though!

yup, i can confirm that
but usually our fingers are way to big and wide to really notice the special effects
i had to use my tippy tip of my finger to be able to appreciate the effect, else i'd have missed it as every single hour i spend with the phone

now, lets wait for the BLN..
maybe home for missed call, back for email, etc etc flashing.
this will be way more cooler than the track ball (if only if it has colors as well).
then we might be able to even do like knight rider style.

[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..
@dusty-:
Do you mean frg83g? frg83d did not help my case. sorry..

Yes I meant frg83g lol

Screen Circle problem

Got my SGSII yesterday only to realize that there is a circle on the downleft of screen. It's very annoying. Went to Telenor today but they had no phones left. Only thing to do now is wait 4 weeks for a new one.
Any idé on what this is? Have you checked your own ones?
imgur.com/a/pLZC5#3guAm

More people have this. I don't know if it went away with anyone? Some say it should go away and the production process causing it.
I see you also have the 1/3 yellowish/darker screen. I am wondering if there is someone who doesn't have this.
Sorry didn't want you to focuss on it, guess you didn't saw yet. but a lot have this(if not everybody).

Haha now when you say it. I was so blind cause of that circle that I didn't notice the yellow/dark thing! Haha!
Do you have a link to any other source that say that they have gotten rid of the circle thing? I searched alot before posting but couldn't find anythin.

dial *#0*# to see the menu for individual color display, or use some app like Dead Pixel Detect , to do more tests.

lol it's funny

Dont have any problems with my screen. Tried setting higher and lower brightness on different background and saw nothing. Are display problems really that common?

I took some more pictures on different backgrounds and it seems like it is only visible on grey. Ar almost.

Only thing to do is send it in?

this phone has so many faults.
all you can do is send it back and get another one... and hope that there isnt something wrong with that.

Am I lucky? My one has no problem. Did you do special things? Or the circle point was pressed? I am worry about possible problem on my sgs2.

Didn't do anything. Opened it, charged it and booted it. Tested it out and rolled down statusbar, noticed directly and all my happyness for my new phone dissappeared.

I guess its the kind of person who owns the phone..
I myself am almost a perfectionist.. well.. atleast when i buy new things.. why would i want a new product with some minor/ major problems on it?
hardware problems.. not software.. since software can be fixed.

I had the circle on mine, top right of the screen. Made a thread about it last week: http://forum.xda-developers.com/showthread.php?t=1078058
Noticed it shortly after taking delivery of the box when I was viewing some photos. It's not visible on pixels where full brightness is used (no matter if it's R, G, or B), but on anything between black and full white it's visible. Sent mine back yesterday for replacement, but I was told by an Expansys-USA rep that they won't have any in stock till the 30th.
Supposedly it's from the suction cup used on the assembly line and that it's technically supposed to go away over time. Expansys only gives a small window of time for returns, and my circle wasn't showing signs of disappearing. Might wanna have yours swapped out, too.

Thanks, was looking for someone else having this problem.
I live in Sweden and ordered from operator Telenor.
They only have a 7 day DOA, so I called them and because all phones were out both in physical store and on the web, they was going to send me a servicebox that I will pack everything and then send it. Hopefully I will get a new one in a few weeks. They say that it can take up to a month though.

Hey there,
I got the exact same thing, but on the right side of the display. I got this thing just yesterday, I live in Germany.
I really do not want to send it back, especially since it seems display problems are pretty common with this phone and there is no guarantee I'll get another one without it.
Anyone knows if this might go away? I have 4 weeks until I have to send it back.

No idea if it will go away, but if you've got 4 weeks, maybe you can see if it does fade over time? I had a really short period of time to report any problems with the phone to Expansys (48 hours), so I couldn't wait.
Man... 4 weeks..! That seems like such a luxurious amount of time to check for problems with the phone.

I can't see anything like this on my phone...
How can I see/make it:-??
