Crazy Backbutton - Nexus S Q&A, Help & Troubleshooting

Hello,
my Backbutton activates itself. While I am watching Videos, or whatever I do it stops shining and I am out of every application I'm using. After about half a minute it's shining again and I can use it normally. It's like pushing the button multiple times. Does anyone has an idea how to fix it? I tried different roms but it looks like an hardware failure to me.

Happened to me as well it is an issue sometimes with samsung but covered under warranty bring it in to sprint
Hit the thanks button if i helped

Sending it back for support is not an option for me. I imported my device from the US to Germany. The support at Samsung Germany told me that they are not responsible for AMOLED devices.
My second problem ist that my IMEI is crashed since I flashed a rom where the dev made a little mistake. So Samsung won't give me any support.
I thought about changing the display but the price for a new one is about 190 Euro. Way too much... I can assemble and disassemble the device but I think that cleaning the device will not solve the problem.
Any suggestions?

It has nothing to do with the display though.
That's likely the part failing:

Verify that the one you currently have isn't simply not connected right.

Thank you. I will have a look if the part is not right connected.
Maybe I have to replace it. But in that case 25 Euro are much cheaper than 190.

This happened to me once. A day later my display completely died. I could turn on my phone, answer calls, etc the touchscreen worked, but I couldnt see anything. I had to get a new one..

I had this problem too.
I flashed a different radio, and boom!! issue resolved

I occasionally get this too. It only comes up when I'm using cm/cm based kernels though, very odd. I'm on matrix right now and it seems to Beowulf, anybody have some tips or suggestions?

I tried a different kernel and it looks like the problem is solved. I know that you should not count your chickens before they are hatched. But I really think that the kernel was the problem.
Anyway, I am just happy that my phone is working properly.
And now I am waiting for jellybean.

What kernel were you using?

It was not the Kernel!

I don't see how the kernel would have anything to do with the backbutton. Although if it worked out then hey that's awesome. Amazing how much I have learned by reading the forums on this site.:victory:

Just clean off the the backbutton, and maybe it will stop or you have a software bug.

So many errors...

Hello im Andy from Austria
I got this phone now since 1 month and its my first
android phone. But i have to say that this is not the phone i expected... It all started when i got the first deep sleep on FIRST day. I thought it would go away after some time but it didnt stop. Then i read this things about flashing etc. I tried flashing many firmwares, custom ROMS and kernels... Nothing helped against the deep sleep.But this is not the only Bug the phone has. Sometimes when i want to call someone i cant hear anything. I have to call like 3-4 times to get it work (very annoying). Sometimes i cant do anything (freeze) , 3g doesnt work , cant boot without putting battery out and in again and even more things. No wonder why the phone got out of stores. Currently im on NeoRom 1.0 . But i read some posts where people got their phone dead randomly, and so i want to revert to default config like i got it from shop. The problem is my binary counter is currently on 4... Is there any method to get it to zero without paying? And another problem is maybe because i have removed simlock from it so i think warranty is gone anyway...
Maybe i try to completly reset the phone and then sell it to someome to get some other phone...
We also dont have any CM and i wonder about this because many unknown phones do have CM... Like Galaxy Y or etc...
It would be better to get some GS2 or GS3.
At least there are no deep sleep issues.

First of all:
Deep sleep is not an issue! It's a good thing, it's the state when your CPU rests and save your battery. The problem you mentioned is called "sleep of death" (when device becomes unresponsive after screen off)
You can reset your counter with USB-jig (if you have Odin protocol v. 2, if you have 2.1 it's a way more complicated))
It sounds stupid.....but did you change the WiFi sleep policy to never ?

Phone occasionally locks and drops data

So, I love this phone but have one issue that seems odd to me. As an example I am currently running pandora and tried opening the xda app which caused what appeared to be a fc but my phone kept running pandora and went to a black screen for a minute then a faded screen which eventually lead to a drop in data (briefly). Every thing was briefly unresponsive... It acted exactly like a reboot without rebooting. When I was able to unlock the screen I had no data service (briefly) and all apps closed. Xda app often fc's which is not a big deal to me but causing the black screen and data drop is concerning to me. I also had this happen when opening the phone info app while running nothing else. Should I be concerned about this? Software or hardware? I am running stock.
Edit: Have also had to reboot due to dropped data but it may have been during a switch between 4G or 3g even 1x.

same thing happens to me, not sure why. I went through and froze all bloat with titanium backup, and it still happens
It's not something I can make happen, just happens randomly. I have 5 days to return this so I would like to figure it out. If a software update would fix it I would just deal with it for now but I'm not sure what the problem is.

I just talked to Samsung on their live chat and they recommended I return the phone and exchange for new. I am still in the 14 day return window so I will ask for brand new even if I have to pay their $35 fee.

The policy is there is no $35 reatocking fee for the same phone swap. Don't let them tell you different. Your phone is DOA. Its a warranty exchange.

No.. tons of us have data issues. My phone hot booted in my hands the other night and it was the first time I experienced it, but I've seen reference to it before.
Your issues are not isolated.
I gave up with tech support and wishing a new phone would fix it and turned to third party development. My first time flashing a ROM. I used synergy and have been really thrilled with it.
Sucks to have to fix a brand new phone. Sucks to be a beta tester for Samsung and vzw.
Sorry for your troubles though.

I did not try wiping the phone because the first one was only nine days old and I had not done much with it. The second one lasted a day and now I am on my third. I really hope this does not happen again. The people at the Verizon store said they have never heard of this..... They think it's an app... I only have 12 apps installed. I don't know what I'm going to do if this happens with this phone. This is frustrating. I do not want to get stuck with a phone that has a problem like this.

Mine does the same thing. Besides the stock stuff, I loaded Pandora, Google Music, Amazon MP3, and Disney's Pirates of the Caribbean: Master of the Seas game. It was nice enough to wait until just after the 14 day return window to start locking up and misbehaving. The only way I could get it back was to do a battery pull. Of course, when I brought it to the store it ran like a champ! If you can get another replacement, make sure it says 'UPDATED' on the box. Those have a newer kernel / baseband and seem to be working better.
All of mine have said updated on the box. I am trying to limit apps for now and will slowly add them if I have no issues.

[Q] Band of touch screen not responding

Hi, I have a problem with the touch screen of the Nexus: a few days ago I realized that a central band of the screen, more or less half an inch high, no longer responds to touch ... To understand, I attach a picture made ​​with 'Position pointer ' from 'Developer options'.
I wonder if anyone has ever had experiences like this, and what do you advise me to do,namely if trying to change the screen, or maybe other most basic solutions (I've read on the web of people who recommend 'squeeze' the screen). Unfortunately the warranty has expired three months ago ...
Thanks in advance

Had the exact same problem with my old android phone, it was after a great fall... I assume that it is a hardware problem and you have to replace your touchscreen to fix it...
But its not a big deal as you dont use that part most of the time and also "auto-rotate" is always present to help you... And if still you cant touch some things then use VNC viewer...

I do not know if it can be somehow help .. The page is in Italian, use google translate .. It is said to 'squeeze' the screen, many people seem to have solved .. Do you say that is our case?

[Q] Screen Flicker?

I haven't seen anything else posted, but I wanted to see is anyone is having the same issue as I am.
Basically, I'm getting what I think are row's of pixels flickering in the area of the screen that are gray.
Here is a quick vid trying to capture it. I can't post videos because I have less than 10 post, you are going to have to trust me for now...
I've also used the dead pixel finder app...everything looks good until I change over to a gray screen, if I stare at it, I can see the flicker...
I first noticed it when I flash Franco r10 (which is what I was on in the video). When I flash back to stock kernel or Bricked, it's much better. But now that I know it is there, I can still see it.
Anyone else having this issue? is there a fix or should I just send it back?
If it matters... LG-D820 White, 32gb
I'm guessing I'm alone with this issue and that it is a hardware problem. :thumbdown:

I haven't noticed anything on mine, but I haven't flashed anything yet. Did you notice the flicker before you flashed the first time?
No I didn't notice anything until I flashed r10. But now that I'm looking for it, I can see it on stock and bricked ever so slightly.
I could live with it on the stock colors, but if this is hardware, I worry that it is going to get worse and not better over time.
Sent from my Nexus 5 using xda app-developers app
I have the same issue and saw it as soon as I flashed franco kernel. Noticed that if you set brightness to 100% it will slowly stabilize but will still come back when lowing brightness. I called for an RMA, but cannot reproduce it as obviously on stock, so i'm also lost as to what it could be.
What did you end up doing?
On mine, I could see it on Stock colors, just not as bad... I returned mine on rma....
I recommend getting the app called display tester.
I don't have enough post for a proper link.
https:// play.google.com /store/apps/details?id=com.gombosdev. displaytester
Look for a bad pixel and go under the banding section for reason for rma.
My new phone didn't have any of the flicker /banding that my old phone did.
Good luck..

Sorry to bring back an old thread but I just noticed this not too long ago and didn't want to open a new thread. I noticed it while I was on stock first and thought flashing something might fix it. I've had mine since the beginning of November. Is the best option just to RMA it?

can you use a SlimPort cable or chromecast to mirror the screen to a TV and see if the flicker still happens?
So you'll know if the problem is in GPU or screen?!

Repaired Nexus 5

Hi! Yesterday I took my Nexus 5 on a trip on top of my car and he decided to take a jump to see what will happen... Anyway, after really exciting jump and after I've found him, he was pretty much destroyed, but still working. So, I ordered new display with side bezels and repaired him today. At first everything seemed to be working, but now WiFi and Bluetooth won't turn on. I've took the back panel off to make sure everything is OK, and then I could turn Bluetooth on. After putting everything together again, it won't turn on. And I saw that for some short period of time, just after I assembled the phone, it had WiFi. :-/
So, now I'm confused.
Is it possible to have software issue, or could it still be hardware?
How can I, anyway, check if everything works with hardware?
Btw. I'm still on stock unrooted ROM. (Wanted to see how it is to have a stable ROM after couple of years )

i'm 99 percent sure it's hardware. software is flashed into chips so that cannot be the issue. it's hard to find out yourself wich part is broken. the best thing you can do is send it to your seller or a near phone shop.
Did the screen flicker what so ever? This happen to me because the screen was not original and I end up sending it back to the seller. Where did you get your screen from? You might have broke something when assemble.
Sent from my Nexus 5 using xda app-developers app
wow! That's what I would call a well shattered screen.
I would suggest you to take it apart again if that's not too hard to do, blow the logic board in case some particles are rolling on it and reassemble it. It could do the trick eventually. Re-flashing stock Rom shouldn't be ignored. At least on a PC, a driver can get corrupted when a laptop falls.

I ordered my screen from vodafone repair service in Nürnberg, Germany and it came the day after. (It costs 140€, and if you want the repair too, then it's 199€. Not very happy about the price...) My replace screen is original from LG and works perfectly. I have to say- maybe even better than the old one. No flickering whatsoever. Backlight is also a bit better because it is equally divided over the screen. Plus, the bezels had new buttons on it, and now has smaller holes on the bottom and power button doesn't rattle any more. From the outside, only the back cover now has two small scratches. everything else is great.
I'm pretty much sure that something didn't connected correctly because sometimes bluetooth works. Tomorrow I'll disassemble it again and see.

Maybe its better to send it to lg for repairs? That's what I'm planning to do. I bought my replacement screen for 150 and it was just hell because so many issues. That's the same price for a repair by lg. Im going to sent it to lg soon but not yet because I been to lazy lol.

The service wanted to charge me almost 60€ more for their work, plus they said that they would most probably reflash the ROM and I would lose all my data...
And I only wanted to save my data. So, for me, this is the best solution.

Sounds like the antennas are not contacting properly. Seems it can happen to anyone upon removing the backplate.
Sent from my Nexus 5 using Tapatalk
I've just disassembled it and reassembled again. Everything looks good. All connections are good and nothing seems to be loose.
I even tried to press the back panel around the camera lens to make a better contact with the antenna, but still nothing.
Looks like this in the WiFi settings...
So, actually, I think it's a software problem and am going to root it now and flash the new ROM.
After that we'll see.
If there isn't any success after that, you all know where to find spare parts for your Nexus 5.
