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

I've had my Nexus S for over 8.5 months now. (since February) I've always loved the phone and was glad that it received the recent jelly bean update.
However recently, my phone is just plain dying. Ever since last week, I've been experiencing frequent freezing when browsing or on instagram etc. It's happened 3 times in the past 5 days. Could it be an app or process that's causing this? I'm not sure.
Another problem I've been facing, (the most annoying of all) is my power button. Yesterday, the power button started to die. I click on the power button to put my phone in standby and bam, suddenly it doesn't work. I'm not sure if some dust could be stuck in there or something. Sometimes when I press it to put my phone on standby, it asks me to turn off my phone, as if I had done a long hold. Strange. The only way to fix the problem is by clicking the power button repeatedly (about 15 times) and then it works again for a while.
One more problem... My phone screen becomes completely useless in one small area of the screen. The only way to get rid the problem is to leave the screen alone for 10 seconds or click the power button on and off.
Now here's the deal. I don't know what to do. Should I send it in for repair and be 'phoneless' for a month? I have not tried a full wipe, and would rather not. I don't think it would change the problem. I need your opinion? Is anyone have the same issues as me?
I'm very stuck, and have no clue what to do.
Seriously...if you have hardware issues you should send it to warranty.
Try the wipe data first you should wipe it and format the "sdcard" anyway before send it to repair.
The power button in the Nexus is the small clicky type that have the tendency to go bad. For the app freezing issues, it maybe time to do a complete wipe and upgrade to 4.1.2. I'm running SlimBean and its extremely smooth.
Use warranty if you have it, or it might be time to upgrade to a newer Nexus.
Mine broke the power button would only work if I'd drop the phone I dropped it too many times and cracked the screen I'd love to get it fixed but im not sure how much Sammy would charge me

A broken screen is pretty expensive, but I think Samsung is pretty nice with warranty! I sent my Nexus S with water damage, (it was dried up, but it didn't boot anymore ) and it got repaired for free! I was in my warranty limit btw

How long did it take for your phone to be sent back? Like 2 weeks? Hopefully not any longer than that.
My nexus with was in repair for 10 days. They replaced my motherboard. Pretty fast.

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

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
Sent from my Nexus 5
Seems like a defected device. Send it back in for a replacement.
RMA it, it sounds defective.
Sent from my Nexus 5 using xda app-developers app
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
Little toddler nephew threw it in a pitcher of water. Sister dried it with a blow dryer and she couldn't get it started to so asked me to try so here I am. She tried to turn it on once about a MONTH ago but nothing since. I'm not sure where to start the trouble shooting so any help would be appreciated. I've taken apart a few devices so I'll be doing that shortly as well.
1) I THINK it's charging but there's no charge indicator at all. A red light came on the first time I plugged it in very briefly but it never came back on again. I'm guessing it's not the battery.
2) I've tried all the button combo to try to get it in various modes, no joy here.
3) The phone vibrates when I hold the power button ( or various button combo ) but the screen doesn't come on.
4) Computer ( Win 8) sees the phone as Nexus 5 but when I click on it, it's blank. The properties show me, LGE, Firmware 1.0, and its serial number. Power source: Battery
5) Several times that I've tried the button combos it would play a little jingle. I'm guessing it's a default LG jingle.
Any suggestions on what the problem will be ? I will probably dunk the thing into alcohol once I take it apart. I'm guessing the display would be the obvious guess but it's a bit pricy to buy just to find out that it's not the screen.
Thanks .
Ahh.. Aren't you suppose to NOT turn it on? You shouldve disassembled it first and extracted the battery then clean and dry. I surely hope it hasn't caused any short circuits from all those multiple tries.
Also the Nexus 5 does not produce any boot sounds.

1) hairdryer - big no. Made it worse.
2) turning it on - big no. Made it worse
In short, don't waste any time on this handset

If you didnt let it dry for at least 24hr min before turning it, then its as good as dead... you maybe be lucky that half the things work but over time, you will find it frustrating not having able to use the full features..
i hope the next nexus is water resistant

Agreed, but like I said it's not mine. I'm still on a trusty Samsung Galaxy 1.
I'm going to pry it apart just to see.
It may still be able to be saved. Open the device up, take a soft tooth brush and some rubbing alcohol, scrub the whole board, breaking away any corrosion that started to build up. If there are any black scorch marks on the connections, then take a pencil eraser and use that to help get those off.
I've heard of using rice to help absorb moisture in cases like his. Might not help now but can anyone confirm if this is maybe a good idea for anyone else faced with a similar problem?

Hi folks,
i am struggling with the following issue and hopefully I find somebody who could help !
After I got a new battery for my nexus, it didn't boot or charge, so I thought the battery is broken. I contacted the seller and he sent me new one. For the time in between I just had my nexus running with my old battery.
So I got the second battery for replacement from the same seller, tried it and nope - didn't boot. I figured this one would be broken again and I tried to put my originally battery back into the phone but it would not run normally now either .
It only booted up a few rare times but the touch didnt work. Since then it only vibrates shortly when I try to turn it on. Afterwards there is nothing more though. Sometimes I can see the backlight bleeding but nothing more...
I changed my screen twice before and I didn't have any problems. So technically speaking I think I knew what I had to do.
Really frustrating. If you could share your ideas with me, that would be fantastic!
Thanks!
I just checked the connection with my computer and that seems to work. I know its not the displays fault so I reckon the USB connector???
Thanks again for your help!
Cheers
Edit: flashed the factory image now and that appeared to work...
I just ordered a New USB connector and see if that'll help.

OK, i think I found what is causing the trouble for me.
I have a loose contact at the connection between the mainboard and the USB connector...
Does someone know if that can be fixed?
Do you think Google will recognise I opened the phone a couple of times?

This is a problem encountered by some others. The connection between the USB/Lcd ribbon and the motherboard has been know to have problems. so first check to make sure it is connected correctly.
I had it happen with one of my Nexus 5 phones. I sloved the problem by using tiny strip of 3M double stickover the top of the USB connector before positioning and screwing on the Motherboard cover . Be careful to ensure that each antannae wire is correctly connected too. You can test everything is working before replacing the rear cover. When you attach the rear cover be aware that it must be able to make a good connection so that NFC is enabled. Just be patient and take your time.
I hope thia helps.
Thanks! That actually helped a lot!
A piece of cardboard on top of the usb ribbon connector actually did it for me!
In fact it's back alive and now I am wondering if I keep my 5' or stick to my new moto x 2014
Thanks again for your help!
cheers
