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....

How many people have problems with the back button

This is the only thing stopping me from getting this phone.. I'm trying to determine how wide spread the issue is. I figured a poll was the best way to see how wide spread the issue was, and whether its worth it to shop around to try and find a working phone

Mine seems to work fine Its not as sensitive as say my girlfriends Incredible buttons, the ones on the Epic seem to work more like physical buttons but they aren't. You have to use a little force for it to recognize and I actually prefer that because I always found myself coincidently hitting the buttons on my girlfriends Incredible when i didn't mean to/meant to press another button

It is really a non issue for me. Haven't noticed it.

I think if you used one of the defective phones, it would have been obvious.. All the other buttons worked without issue. The back button on the one I tried wouldn't register no matter how hard or how long you pressed it - some times. Some times it would register for a light little hit, other times I'd be pressing down pretty hard and nothing. By the second or third time, you'd feel the feedback buzz (which was pretty cool), and it would actually work..
It was sort of funny, the rep who was trying to sell me the phone started off to try and down play it and say "I'd just have to get used to it"... until I gave it to him. In the end, he agreed there was something wrong.
I didn't want to make the guy try other phones because I was planning on purchasing the phone from my business' phone retailer... It would have been sort of wrong to make the guy go through 3 phones and just leave if I found one that worked..
Not sure if it matters, but what state are you guys in? I'd imagine that similar batches ship to the same region.. I'm in LI, NY

Absolutely never had a problem with the backbutton.
All 4 of my capacative buttons work with light taps AND full presses.
Its hard to tell wherethe buttons are when the lights time out, and you have to hit the button in the right spot for it to register. My nexus was the same with its capacatives.
beamed from the stars on a Epic 4G

While I don't think there is an issue with the buttons persay. I was doing some testing and seems there might be some "lag" I was having this issue more with the home button at times. One time after i knew i clicked it i let is sit. took a few seconds but continued to do its thing... So maybe its the same with the back button as well. Next time after you click it once let is sit and see if it proceeds.. that way we know its a lag issue vs button issue. A lag issue would be easier to fix I would think.

First of all NeonMonster, thank you for being awesome with the Nexus One back in the day of rooting it and changing things! Haha.
Secondly,
I had a defective Epic 4G. The back button was the worst of the bunch. I would have to hit it 10-15 times to get it to work. But it wasn't the only faulty button. All of the capactive buttons seemed to falter just about anytime I went to use them.
I went to Sprint the next day and explained the problem and she said I was the first to bring it to their attention. But long story short, she exchanged it and the buttoms work perfectly. There aren't as sensitive as say the EVO or Incredible but they work as intended and the phone I once thought was hopeless and I hated, is now a phone I'm contemplating keeping.
So there are definitely defective devices out there but it is as simple as going in and getting a replacement.
Thanks for everything you guys do!

I picked my Epic on launch day and all was well..my brother on the other hand just got one this afternoon and after we got it activated i hvae noticed his has this same problem.

I didn't notice any lag... Again, I think if you have a defective phone, it would be obvious. A press just didn't register, even if you'd wait..

Yeah, there isn't a lag. It just straight up does not register any contact. You have a defective phone. I took mine back and got a new one and it works EXACTLY like it should. Night and Day!

Buttons work great.

I bought the cheap screen protecter at RS and had it put on in store, my button presses were instant. When I got home and decided I didn't like or really need the screen protector, I took it off and then my button presses didn't register as smoothly may be a quick fix for some that want to use a screen protector.

Aww from the nexus forum?? That was such a fun time! The nexus is truly a phone meant to be rooted. kinda miss that thing but the keyboard on the epic is too good.
But yes, there will always be phones that are defective and need to be replaced.

yeah i noticed some lag on mine. i also tripped out when then home and menu buttons were switched (compared to the evo) and kept pressing the wrong buttons.

its looking like a 50/50 so far on getting a phone without tis problem :-\

That logic doesn't work.
1. Most people that don't have the problem won't vote.
2. Remove the people on the last option and it's 70/30 (at the time I write this).

You might be right with #1 (I don't know), but as for #2 it is 15-14 for people who are and aren't having some sort of problem with the back button (or other buttons)..
I do agree that this is far from scientific, as people who have never used the phone are likely to be voting..

Only read because I had the issue
Yep. I think you might just skip over this thread all together unless you've had the issue. Personally, I got one phone with the issue, exchanged it, and got another with the same problem - although not as bad as the first. However, I haven't returned the second one yet and the problem seems to have gone away. I'm not sure exactly how these buttons are engineered, but I'm wondering if more people with this problem will simply see it go away. FYI: the first phone I had was getting better but it started out as more of a 70% fail/only work with hard mashing.

My back button has a mind of its own :-( it presses itself when it wants to. Very annoying.

My first phone didn't have a working 4g radio. The second had this problem and it is very annoying if your used to a working button I returned it to radio shack. My third phone is perfect in every way.(hardware wise) this was all in the first week of the phone release. I would deffinetly go back and return it.

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?
Sent from my Nexus S using XDA App

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.

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

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.

Home button making a cracking sound

I am afraid the home button on my SGS4 is somehow defective. It still functions properly, but it is making all kind of cracking sounds. It almost feels loose. I checked on a SGS3 and a Note 2 and none of the home buttons were exhibiting the same behaviour.
So my question to you guys is, does your home button feel solid or is there and cracking with light touch?
Please take a look at the video I made.

On mine, i can hear and feel a slight crackling noise with light touch without pressing the key all the way down. The button feels solid, tight and works just fine AFTER the initial press, but it bothers me that it does that. The shop people wouldn't consider this as a defect since it's so minor, but minor enough to annoy a fussy tech person like me.
Does anyone else have this problem?

Nice and solid on mine. No noises what so ever.

Has it gotten worse or better since then? I wonder if it will go away after a few months of button mashing?

Just wondering (it might be stupid from my side, still...) did you remove plastic protective foil from the button. Usually it gets stucked on the button and it is hard to spot...

I switched my I9500 for a new one and the home button is now perfect with no cracking noises.

Yeah, I got this problem as well! Mine is not loose just like yours, but if you press softly on the button you can feel it move before the key activates.
Then, when you put the phone away, the problem returns after 10 mins of not being used. As if the plastic material "expands" and gets jammed. It really annoys me, because the phone was very expensive for me 800USD here in Denmark! And i expect a perfect phone for that kind of money!
Have anybody got a solution to this?
I am not willing to return the phone because they are only going to send it to get repaired, and I can feel it in my gut that I will get a phone back with more errors than before lol.
And how have it developed since? Gotten worse or better?

Too early to tell. It's really irritating though. I resulted in downloading a software home button to use instead (to prevent it from getting any more worse). Swipe Pad and Pie Control are both good at simulating the hardware home button - no root is required either.

i just noticed a slight cracking noise on my home button as well. It is more apparent if you press towards the edges of the button, and kind of seems like a 2-stage click. annoying

Thanks for the information! I like Pie Control best of the two!
Although, the problem wont solve itself by avoiding the button, so i think i will press it even more, just to see if the problem persists, gets worse or fixes itself. In my experience the button has gotten worse over the past few days. The shop wont take the phone back because they label it as "self fault" (dont know the english term), they think I am the problem and have not taken care of my phone. This is ridiculous! I have now sent at mail to Samsung Denmark to see if they can help me!

I've got something very similar with mine. It feels slightly loose and not the solid feel it had when I first got the phone. I'm interested in how you get on too.

Mine moves slightly which is expected, but no cracking sounds and feels solid

My home button does the same thing. Although I think it started after I tripped and dropped it at the top of a staircase and it bounced off every stair all the way down *facepalm*

+1
Power button is wonky too.
I'm really unimpressed by the overall build quality of this phone - especially for its price.
Oh well. "First World Problems"

My home button feels absolutely fine, on the other hand, my power button feels sticky and spongey when I press it, still works fine though.
Nothing like my Galaxy Note 2 which clicks when pressed.

Mine started "clicking" few days ago. It drives me mental when trying to navigate through at night.
