[Q] Possible hardware problem of the back button?

I just wanted to share this, since I was able to replicate this issue with three different phones, also asking if other people are having the same issue.
I am using my Samsung Nexus S for three days.
I noticed that the back button (the first capacitive button on the bottom left) appears to have an hardware problem.
Basically normally it works fine, I mean when I'm not using the phone for some hours.
Then if I start to use the phone, after a moderate use (example installing applications from the market, browsing etc) the button gets less and less sensitive.
After some minutes it gets really annoying.
To make it work it is necessary to use a really stronger pressure with the finger, and it is not even always working!
I am planning to return my device, but today talking with some people/colleagues I discovered that two of them have exactly the same problem.
I'm suspecting there is a batch of Nexus S phones with this glitch, I am curious to know how many people have the same problem.
Note:
At first I thought it was a general issue of the capacitive buttons. But I can't replicate the same problem with the other three buttons, they work very smoothly just lighltly skimming the finger over them, even after long usage.
Anyone with the same problem? What is your experience with this button after some usage?
Cheers

I want to say that I noticed something similar the other day, but it was short-lived, and I'm not 100% sure. It wasn't long enough or bad enough to make me think the phone is defective, but I'm a bit used to funky capacitive button responses from my N1 days.
I can't reproduce the issue right now, though. How much usage are you talking about needing to duplicate?
Does your phone get hot, or feel hotter than normal when this happens?
I'd see if there's some particular pattern or software that seems to trigger it if you're interested in trouble-shooting.

The problem goes away when I don't touch the phone for a while (it seems that 1 hour is enough to reset the problem).
It seems "recharging".
Then with normal usage, nothing in particular, just even browsing in the settings/maps/market/browser etc., in few minutes the problem appears. The button definitely loses his "power".
It's very annoying, and my friends confirmed the same behavior.
EDIT:
Forgot to sat that the phone is not getting hotter, everything else is really normal.
Cheers

Mine definitely can be used for much more than a few minutes without the problem you're describing appearing.
I'd take it back. Factory reset the phone to protect your private data before taking it back. After the factory reset, you might want to test the behavior again, if it went away, the phone's not defective, you just had some software glitch.
Reminder, factory reset erases everything on the phone, so if you do it as troubleshooting step, be prepared to have to set the phone up from scratch again...I'm sure you knew this, but just covering my butt in case you didn't. It's a good trouble shooting step no matter what if you don't mind the hassle of re-setting things up.

I have a similar experience with the back button. Not sure what to think yet.

I had a similar problem when I had the Vibrant. Just exchanged it and luckily I got a better one without any problems. I did find out though if you are using the screen protector that came with the phone, it can cause this type of problem.

No problem, I will try everything tomorrow. This is not my primary phone (still loving my rooted Nexus One with CyanogenMod 6.1.1 ;-) I can't renounce to the colored trackball for the different notifications), but just a "dev" phone for testing purposes.

The app NOLED from the Market may interest you if you can't live without trackball style color notifications. Seems to work fine when I tested it.

Thank you, giving it a try.
Anyway, today I factory-reset my telephone and the problem of the back button is still there. I am returning the device.

Back button non responsive
Hi,
I just got my new nexus S (about an hour ago) that I was really excited about and am faced with a problem with the back button too.
Its got factory settings, so it cannot be a downloaded software issue. Also, I have not yet charged the battery at all, its still running on the same battery power that it shipped with.
The other buttons at the bottom of the phone (home, menu and search) all respond fine, its only the back button that does not seem to work. After going through this thread, I tried long-pressing the button, hard-pressing it, pressing just above it, below it, etc. It just wont respond. I had removed the screen protector it shipped with, so that cannot be the issue either.
If this is a known hardware problem (i.e. others have faced it too), irrespective of whether it is acknowledged by Samsung / Google, I'll return the handset. I do not want to spend a fortune and be landed with a handset that does not work - forget working as desired, but it does not seem to be working as designed !
Thanks & Regards,
Rohan

Yep. Definitely a problem here with the back button. There's also two other threads here about it.

I'm having similar problems. I have to touch the button just right for it to work properly

I was experiencing the same thing with my Nexus S, wasn't sure if it was the case I was using! Took of case and still had problem. I eventually returned mine cause it seemed like it was getting worse! I have a new one worth no problems, definitely a hardware problem! Return it!

those buttons work over the heat of your finger. thats why after use it doesnt get as responsive. its because the screen is also heated and the heat of the screen is effecting the buttons. thats why you need harder pressure for the phone to understand this is your finger.
same issue was with Nexus 1. less responsive buttons. thats why there is a bigger gap between the buttons and the screen for galaxy S phones. i dont know why they did such a thing again with the nexus S. its like samsung didnt learn from anything from HTCs mistake.

They work with capacitance, not heat. Hence it being called a capacitive screen with capacitive buttons.

I think this is true ...
I have an HTC Desire with AMOLED screen.
When I play a finger intensive game, like "SkyForce Reloaded", after some times, the touch is not registered.
Then I must stop for a while, or change finger
Try that, you will know what I meant.
But, I don't have issue with the back button on HTC Desire because it is a hardware button. I am just trying to explain about loosing touch registration because finger interaction on (s)amoled screen.
PS: SkyForce Reloaded is an old school shot'em up game where you control a little space ship with your finger, shooting enemies.

The Desire's digitizer is the same Clearpad 2000 which is used in the Nexus One (and quite a few others), the problem there is that it's pants.

lol, isnt called like that because it registers the heat from your fingers. thats why if you try to use a pen, it wont register . and thus. the screen is NOT resistive type "where it will recognize anything since its being pushed by force ? "

from your link
"A capacitive touchscreen panel is one which consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO).[7][8] As the human body is also a conductor, touching the surface of the screen results in a distortion of the screen's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing.

Xoom touchscreen "has gone mad"

Well guys, I don't know how to describe better this think
These are the facts: this morning I received my new Xoom WiFi from Amazon; I'm in Europe so another courier shipped my Xoom from US ground to my home.
After unboxing it, I charged it and then started playing with it. After a while, I waked up the Xoom from sleep mode and I noticed that there were several "fake touches" per second on the screen, or to better explain, I could see on the display the same reaction that would be if one touched repeatedly and very fast on the screen. This made the tablet completely unusable, or even "dangerous" (it clicked a "Like" button on facebook and sent a nonsense email all alone, without any intervent by me). The first times, I just waited and this abnormal acting disappeared. After a while, a reboot was needed to fix this condition. At the beginning this problem showed up only after locking and unlocking the screen (waking up the Xoom from sleep mode), but after some hours of use it has slowly deteriorated: at this time the Xoom does this always, from when I turn it on, to when I turn it off (and believe me, it's really hard to turn it off) and the tablet it's COMPLETELY unusable.
For now, the problematic part of the screen it's only the left column (holding it in landscape, with the front camera on top).
What can I do?
P.S.: I buyed it on April 5th.
P.P.S.: obviously the Xoom is "virgin", with no hacks of sort, completely stock

Have you tried doing a factory reset? See if that helps if not then you might have a defective unit.

How do you do a "factory reset" on the Zoom?
"Xoom the Monster" The beatings will continue...

If the protective plastic cover is still on the screen, it could be causing problems. Other wise I'm inclined to think there is a static charge involved. It might sound silly, but try holding a metal water faucet with your other hand while you touch three screen.
-Total speculation on my part.

Yes, I did a factory reset: the only result was loosing the songs that were included with the Xoom

It's what I thought too. There's no protective plastic cover anymore: I removed it before turning on the Xoom. However, I've tried with a calorifer before, and I got a shock. Now I tried with a water faucet, touching it for a while and the malfunctioning seems to be gone (for now), but now the touchscreen it's not so precise (or so it seems). However it seems strange to me. I never had such problems with any capacitive touchscreen before. Is it solveable? Is there a way to be sure that this is solved? It's a defective unit?

Ok, it was a temporary solution: the malfunction came back. Then the "holding grounded metal" trick worked again, and then the malfunction came back, and so on...

I have also problems with touch screen, but my problems are much stranger. On my Xoom there are two possibilities if I turn it on, I ether have touch controls or not. Forced reboot is the only things that gets me touch controls at all.
But back to your problem, have you looked if dmesg output shows any errors? Download Terminal emulator app and write dmesg.

I suggest you return it. The components are so sensitive to electricity and there are two huge potential static generators; the battery and the flash capacitor. You could toast it at any time, and might'vs already baked a sensor for all you know.
Take it back fora new one.

Well, I tought about it, but I buyed it from Amazon US and I'm in Europe: I really don't know how to return it; I don't even know how long the returning period is. However, you could be right, so I'll try to talk with Amazon or with Motorola support service.

Forced reboot (not just a reboot) seems to help here too, but only temporary, because after some time (or if I lock and unlock the screen) the malfunctioning come back.
I caught the dmesg log. Here it is an extract during the malfunction coming out
Code:

All I did here was to press the lock button (locking and turning off the screen), press it again and unlock the screen. It seems pretty normal to me. However I have the whole dmesg log (from turning on to force reboot) of that session. I can post it if it can be useful.

The part you posted is normal.
I would be interested to see your dmesg output after a forced reboot, to compare it to mine.

faced with similar issue. Randomly some fake screen touches are taking place. Only pressing the on/off key helps to get it back to normal state. Do anyone have any suggestions or ideas?

Flashed with Tiamat ROM but the issue still remains. Xoom is going crazy.
I'm afraid it's kind of hardware problem, maybe something related with static electricity. Not strong in this.
Can't return it to Motorola as it was bought it US by another person
Anyway, thank you, ryan562
Any other ideas/suggestions are welcomed

Have you applied a screen protector on it that required liquid to install it?
My Xoom touchscreen briefly malfunctioned the other day as it kept thinking I was touching the lower right part of the screen. A power cycle cured it for now, but I hope it does not return.

I applied screen protector, but not very carefully. Leaved some air bubbles. I thought they were causing the issue and removed the protector completely.
Right now there is only silicon case. I was able to reproduce the problem without case

[Q] Should I use stock when I take this for repair?

For a few months my phone has had a problem where the screen will take control of itself or become unresponsive, it's not the phone being slow, because hardware keys respond perfectly. Scrubbing the screen with a Lysol wipe helps sometimes, but I'd rather just have the problem taken care of (it seems like it's caused by fingerprints on the screen, which isn't a problem on any of my friends' SKs and initially wasn't on mine either).
Anyway, when I take my SK to T-Mo, should I flash a ROM that at least looks stock for warranty purposes or will they not care?
If I do need to go to stock, how would I go about doing that? As far as I remember, I've never taken a backup in recovery and never ODIN'ed (stupid, I know), so I've no idea what to do. I can flash ROMs perfectly fine, but going back to stock is a mind-boggler for me (disabling Voodoo, etc).
Thanks

Mine always does this.
1. The optical trackpad detects the sunlight, strong indoor lights, etc, as movement and causes spurious scrolling.
2. Water on the screen or a finger just outside the boarder of the screen causes the touchscreen to get confused and either not respond or move on its own.
3. The touchscreen driver is prone to crashing. About half the times I want to answer a call or something, I need to toggle the screen off and on with the power button before it'll work.
None of this is because the hardware has broken. 1 is due to a bad design, 2 is inherent to touchscreens of this type, and 3 is just bad programming.

Ha! I have to do #3 all the time. Glad to know it's not just me. Ridiculous.
Also FYI, #1 never happens to me. I see people here curse that damn sensor all the time, but I have never had mine move randomly in sunlight, and it generally works pretty well for me as arrow-keys.

I also do #3 all the time, and have had problems with the optical trackpad in the past (I've since disabled it).
What the problem appeared to be was that my fingers are oily or something, explaining why wiping the screen excessively was useful. I passed on taking it to the T-Mobile store and instead ordered screen protectors from Amazon. No problems since I applied one.
Has anyone else encountered this, or is this a unique problem? I got through nearly a year without having this problem, so maybe something went wonky in the screen. Anyway, problem fixed

Touch screen problem

Hi guys,
i'm having an issue with my HTC u11, basically when i'm using the phone randomly the swipe down screen (when you swipe the screen down from top to bottom to get the notifications) comes down.
For example if while i am writing a message then drop down screen will come down when i'm typing, i then have to swipe up and continue and again.
it happens more or less all the time and is quite annoying.
any ideas?

its okay, issue resolved. NOVA Setting had gesture switched on. Swipe down for notification menu, this was the issue. lol
PLease close the thread.
Thanks

Well i had the same issue. Was driving me mad! Thanks for the info.

I don't use nova and I have been experiencing this same problem so now what?
Sent from my SM-G955U using XDA-Developers Legacy app

Yeah i though the Nova setting had solved it but it seems to be back again for me, although not as frequent.
I also experience the keyboard collapsing randomly too. Anyone get that?

Hi guys, thought nova got rid bit guess not. I still get the issue. Would this be a software issue or do I have a fault with my hardware?
Any tests I can do?

I reported my issues to HTC and they replied with the following :
To test the function of the touch screen please follow the below steps
1- Dial *#*#3424#*#* > the press accept.
2- From the options, mark Line drawing test > then press run.
3- Then start drawing on the screen to check if there are parts that do not respond
The screen does not have any dead or unresponsive spots tho and the test passes without any issues.
Does anyone experience the keyboard collapses also?
I might do a full reset soon to see if that helps any. If not i will be getting back in touch with HTC.

Did all this as well, and all the tests that I've ran pass just fine. I've also done a hard reset and it didn't make any difference. I do notice that after a soft reset that it takes a while for it to happen again. It's annoying as hell so I will be monitoring this thread. Whatever you find out from htc please update this thread so we can figure out what the hell is going on.
Sent from my SM-G955U using XDA-Developers Legacy app

I also done the test and it was a pass.
I'm certain it's something to do with the software of htc. The UI has to have something wrong with it. Mind you it hasn't done it to me today yet and I'm nearly at the end of the day.
Has everyone got a case? Can't be case interference?

Exactly same issue here. Very very annoying. As a HTC fanboy I'm quite dissapointed. Phone less than 2 months old. I actually spoke to HTC today, they said they would have to book it in for a repair... Takes up-to 10 business days... I said this is not acceptable! Waiting for a email back.

I have emailed HTC back advising them that others are reporting the issue so unlikely that it's a single handset issue.
Awaiting their reply. No doubt it will be along the same lines that @dobknobby got and have to go through the 10 day repair process.
Will update when I get a reply.

I have had the same problem, and I have done the a lot of the same steps;
I tried several different screen protectors, thinking that was causing the issue. I have had no screen protector on for the last week, and yep it still happens.
Shut off edge sense, still happened.
Tested the touch screen, and everything passed.
Last night I noticed that it seemed to be related to the pressure I was putting on the screen, if I pressed down harder on the screen and slide my finger left or right or up the notification bar would come down. Did some more testing and for awhile I was able to reproduce it about 50% of the time. I rebooted the phone into safe mode (hold power button down and then press and hold the power off option for about 5 seconds it will ask if you want to reboot into safe mode). In Safe mode I could not reproduce it, Safe mode disables ALL third party apps.
WARNING: when I rebooted my phone to go back to "normal" all of my widgets and groupings were not on the screens, had to re add them.
After doing all this testing last night, I have not seen the notification come down, but like someone said it seems to get worse the longer the phone is running before reboot.
I was going to do a hard reset, today but that sounds like that may not help.
Not sure if this is software, but with the testing I did last night it seem to work fine in safe mode. However I have wondered if it is something with the screen, like is flexing enough for the sensors at the top to react to the pressure/flex.
Well keep testing and report back.

I'm also having some issues with the touch screen, but it mainly happens with the keyboard. I like to swipe to type, but lately I've noticed that it gets really jumpy, causing thing errors.
At first i thought it was touchpal so i installed Gboard. Problem still occurs.
I also removed my screen protector and tried did the touchscreen test.
---------- Post added at 07:30 PM ---------- Previous post was at 07:08 PM ----------
I ran the line drawing test a bunch of times and yes, i now do see that mine fails to draw a continuous line on occasion. It only happens in the keyboard (squeezable?) area though.
I'm worried now that edge sense is damaging the touchscreen.

OK, i have ordered HTC u11 this morning from amazon, but i guess i will cancel my order. Had many problems with htc phones in the past. Saw many reviews and thought that this one is perfect with no flaws... Ahh..... Already ordered some accessories for my new device... It's really a shame to read this kind of threads. Hope you guys will find a solution and hope that this won't be a hardware issue.

Does your keyboard collapse when you are typing? That happens with me. Really frustrating when you are typing quite fast then the keyboard just disappears. Then you end up tapping a link or something that was behind the keyboard. You then need to go back to the page you were on and start typing all over again.

Are you running app killers? Stop boost+ auto. Apps updating from gplay can cause you to be kicked out of the keyboard, it can also pause/stop YouTube vids.
The edge sense system is 2 sensors stuck to the inside of the edge of the device, along the aluminium strips, they shouldn't interfere with the screen at any time.
Sweaty hands and greasy screen can cause the screen to misread your touches and gestures.
Running low on internal memory (sdcard) can cause all sorts of issues. Make sure you ALWAYS have a couple of Gb free.
Try to replicate the problem in test mode.

Exactly same issue here. Very very annoying. As a HTC fanboy I'm quite dissapointed. Phone less than 2 months old. I actually spoke to HTC today, they said they would have to book it in for a repair... Takes up-to 10 business days... I said this is not acceptable! Waiting for a email back.

Same here, only I was told 7 to 15 business days. Offered to give c card to have a replacement shipped, but that is no longer an option with HTC.
So when I washed my M9, I was without a device for 2 days, but now that their phone is crap, it's going to be 3-4 weeks.
Unhappy....

P30 fingerprint picture showing up often

When my P30 is placed on the table (I don't notice when in my pocket, duh ) it lights up the "Place finger here" in the bottom.
Does anyone have an idea why that happens?
It's not like the table is moving or anything to trigger a read, so why is it showing?
Could it result in burn-in?

I have same problem, it could result in burning, but i have no idea why it shows up

It is annoying! I've turned it off in favor of a PIN to prevent burn-in

I wrote and email to Huawei and the replied rhat IT shouldnt result in burn-in.
And if I didn't want to risk it, I could turnering it off.
Not really a valid answer...

I'm surprised their IT is not aware of the latest OTA from last night, which is version 9.1.0.124(C431E3R2P2) and fixed the problem. The annoying fingerprint symbol no longer randomly appears but only if I move my phone (and in the pocket it would not show as the proximity sensor prevents that from happening, which I have tested).

That didn't solve it for me. It still shows up.
I still use the screen protector that was on the phone when I bought it. Did you remove yours?

I've kept it on. Normally I'm not the kind of guy who uses one, but this was placed on very well I still find the screen to be excellent, it does not bother me. Have you immediately pulled yours off or can you describe a before/after experience?

I just tested at my desk and it came up 9 times in a minute.
I still have the protector on. Never removed it as it is placed nicely.

Is that the standard P30 you have on .124? My P30 is on .113.
I have this issue too, the symbol shows up several times a minute. I have seen others mention elsewhere that this could well be a hardware issue?
I'd just assumed this was a software issue but if it is hardware then it may be time to return it?

Yes, it's standard version... After I bought it (first day), phone was updated with this version ...
After I switch off the phone (and put it on the table), symbol shows up for a few seconds, then disappear until I move the phone ..
Maybe you should try first with .124 version .. ?

Hi
My p30 is on 115 update and still has the same problem

Anyone try without or with a different screen protector?

I have found some kind of solution, but by some reason it does not work all the time. Settings- Smart assistance- Shortcuts & gestures - wake screen - Double-tap screen to wake. Activate that option and reboot the device.
But as I can see, that light might be used as some kind of notification light since it blinks when there is something, like e-mail, message and other things that need attention. When there is no internet connection it is not blinking until you move it.
All of the above are just my personal observations and I don't insist that they are 100% correct.

Having this act as a notification indicator isn't a bad theory, although the frequency of it appearing seems wrong for that kind of use.
Personally, I'm bummed at the lack of notification light, something I had been relying on for years with all my previous phones. I might end up taking advantage of the OLED screen and just make it keep the screen on instead.
My phone updated from 111 to 121 today (I guess we have different build numbers in North America), I still see it flashing from time to time while it sits on my desk.

Update: I tried with a tempered glass screen protector and now it doesn't show up unannounced anymore.
I think it is an issue with sensitivity of the screen.
