Touch Screen Problems... - Nexus 5 Q&A, Help & Troubleshooting

My touch screen has been acting mad the past few days - it barely responds to my touch and it acts as if someone is randomly moving their fingers around the screen. Tried rebooting, reflashing, and I'm even back to stock now to no avail. I think I'll have to send it into warranty.
Anyone else experience something similar?

You've done all the right things to trouble shoot the problem. I'd rma the device. I don't think you can do any more than you already have

Seems like a defected device. Send it back in for a replacement.

RMA it, it sounds defective.

Yeah I am sending it in... it just seems weird that its acting up after I've had the device for almost a half year without any problems. No worries - maybe I'll get a device from the newer assembly line (I have to original N5).
Thanks guys can't wait to be back in this forum

Screen stopped working.

I'm on a business trip and have brought my Note with me which is in a cover and carried in the notebook slot of a backpack. Once I arrived I noticed the tablet, though on, appeared to be locked up, no response to touch or pen input. Forced a restart and touch stated working until I pulled out the pen and then everything froze again, including touch. Tried this several times with the same result. Did a factory reset thinking something got messed up with the software which is invoked when the pen is pulled but no help. Something has happened but to what I don't know. Was thinking about returning anyway for a 32gb version so now I guess the decision has been made. Still curious as to what happened so I might avoid it in the future....
One more thing. In the notebook compartment I also had my series 7 slate which also was in it's own cover as well. I can't see where that could have been a problem as there was plenty of room in the compartment. I guess having another semi hard object there may have stressed the screen of the note but that doesn't seem likely.

Yep, some of us have had this problem, the exact same problem. I am returning mine to Amazon and receiving a replacement. I don't know if the update has anything to do with it or not, but I am going to keep the update off of it for a while to see if the problem happens to my new one.
I've had the update loaded since the day it came out, what a week ago or so. Wasn't a problem

Same exact thing happened to my 1 week old note. Did the reset and still the touchscreen would not work correctly. Crazy thing with mine I could force a restart just as it came back on the touch screen would work fine until I let the screen turn off then it would not let me unlock. Had to return it.

Me too. I got my second unit last Friday and no problems yet but no update available either. It seems that Samsung pulled the update for some reason.

[Q] Lately, a bunch of Nexuses have been randomly committing suicide...

Okay, so yesterday, my friend comes to me saying his Nexus S (Sprint) just randomly quit working for no reason. And then his phone is totally stock, no root, no bootloader unlock, and no custom recovery. So I go home, plug this Nexus S into the charger, but the screen remained blank. I unhooked it from the charger, then decided to plug it into the computer. The computer made no sound, did nothing at all. I tried all possible key combos in existence. The only thing the Nexus did was to become warm. I furthermore researched about this issue all over Google, and I've found plentiful Nexus S users report that their Nexus S quit and won't give any sign of life this month. Today, ANOTHER friend came to me, but this time, it was because he forgot the pattern lock to his Nexus S (Sprint). No biggie. I just went into the recovery, and wiped data (since he also forgot his Google account). I wanted to use this Nexus to see if I can diagnose the other Nexus. So in my hands, I hold 2 Neuses. One bricked HARD. The other healthy and free. I just want to confirm, there IS AN ISSUE W/ OUR NEXUSES that makes them die, and we have to figure out what is causing this to happen. We need a solution. I need other Nexus S users to confirm this issue by commenting within this thread.
Just the past couple days my Nexus S has been on the fritz. I've always been able to overlock/underclock, but now if I touch the clock settings, it reboots. I cant even set the max frequency to 800mhz any more. I've tried nearly every rom and kernel and I believe its the just the hardware finally degrading. Also the responsiveness of the device is hugely slower than when I first purchased the it, I have to wait about 10 seconds after unlocking the screen to be able to do anything, and Im on completely stock now.
Really hoping for a good nexus phone to come out this year.
Looks like there are some design flaws with this device like the power button. Not sure there are any solution beside using your warranty if you have one and buying a different phone.

Agree with you there. I don't believe there's a point trying to look why exactly some Nexus S die. It's specialized electronics and without the knowledge you could pretty much be poking your finger at everything and nothing for the rest of your life. And even if you find out the issue, doesn't mean you can fix it yourself... :/
Easier to just send it for repair and be done with it.
Edit: When I first got my Nexus I sent it for repair to Samsung. Came back with "BGA failure" on the work sheet. Bad soldering? Who knows.
Maybe, maybe its the CPU, this thing cannget hot sometimes. Maybe a contact messes up. Samsung is notorious for good hardware just dieing.

Touchscreen stopped working after soft brick...

Ok..
I had this phone for a while and I started using it again recently. I have fully replaced the digitizer/lcd bezel before with no problems (been a phone repair tech for 10 years) And it has worked fine.
The other night I reverted it back to stock because it seems to be the only way to get a constant data signal. Worked fine. I then updated it to the newest OTA update without a problem.
I then rebooted it and it stuck on a black screen loop with the buttons going on and off for hours. I spent 7 hours trying to figure out what was wrong, flashing, re flashing.. Nothing. Finally I get CWM recovery installed and find out my SD card is fried. So I put a new one in, and transfer over the roms I want t flash. 3 different roms, all with no touch screen.
Revert back to stock, still no touch screen.
Could something have gone bad on the board to have caused this? Is there something system wise not getting wiped that may cause this? Its to much of a coincidence that the touch screen and buttons would go out after all this happened.
Any help would be appreciated. Im waiting on a new digitizer now to check because Ive already gone over all the connections. But if its something software wise, Id like to try that before doing another digitizer replacement.
Thanks
funny you made this thread. i just got my hands on a soft bricked g2x that was stuck on the blue lg logo. after a quick nvflash it boots right up......but with no touchscreen. not sure if it ever worked as im not the original owner.
but i'll be keeping my eyes out on this thread for sure!
Id give a pretty to see inside both of your phones. Sounds like a bad contact on the ribbons.or one of them may have been ripped during a screen installation. I've never heard of the screen just up and quoting working without some major stuff happening to the phone. My guess is these screens were replaced with the wrong screen.just a guess though.

I have done phone repairs for quite a few years, It wasnt a wrong screen and has worked fine for a year since its replacement. I have already opened the phone again and made sure all contacts were fine. What Im trying to figure out is if there is maybe some part of the system/boot that holds the touchscreen drivers and they have bee erased?
Again, I find its a huge coincidence that it worked fine up until this happened then as soon as its booting again, stops working... Which is why I think its a software issue.
Try touching the corners of the screen after booting up start with the top left and go clockwise. One of the roms used to mess up the connectivity between phone and screen. And that is supposed to reset the touch screen. A old g1 trick

[Q] Screen drop outs and now always black, why?

Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help
Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you
I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.

even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past
Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well
So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(
Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?
There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

Nexus 5 black screen

My N7 4.4.2 Not Rooted has been playing up lately. For the 2nd time in 3 days, I picked it up and it wouldnt respond. I could hear the screenshot being taken so the phone was on but the screen was black. It vibrates after using the power button and it finally boots up again. The phone has been perfect for about a month and this error only started recently.

Do a factory reset. Keep in mind that this will wipe your internal storage so be sure to back up and data, photos, etc. before hand. If that doesn't fix it then flash the factory image over. As to how, refer to this thread.
Your problem should be fixed after the Factory Reset though. Good Luck!
Thanks. I was hoping it wouldn't come to this but oh well. Is there a cause for this?

Were are talking about the N5 right?. I had this issue with my G2X a couple years ago. It turns out that after I took it apart the flex cable looked like at had been torn a tad bit. This sounds like a flex cable problem. Software could be the issue and a factory reset may help. However in my experience that's usually a flex cable or pop connection. Send it in if the reset does not work. Don't bother trying to do this yourself. It may be the front panel flex cable. Or the pop connection of the main board. When these cables are made, they are literally thrown into barrels and sent to The front panel assembly line. So chances are. One of these flex cables suffered some damage. Same goes with the tiny connection on the main board. These tiny pieces are put on one by one. I think robots do it. The device turned on for their tests. But the long run? ...Well you get the point.

Im just facotry resetting my phone right now, i'll post later the results after a few days of testing
Well? did the factory reset work? I have this issue and it's driving me nuts!!!! I read somewhere that squeezing the case helps, and indeed this seems to work something, to it looks like hardware issue to me
black screen nexus 5
I was totally desperate with this random black screen. I tried everything including change of flex cable and also screen, but the same random black screen
I changed the 2 years old battery with a new one and.... ooff... this resolved my problem .no black screen anymore
I hope that, with this solution, I give You another direction of thinking about what is causing this annoying problem
