[Q] Nexus Screen gets colored pixel snow - Nexus 5 Q&A, Help & Troubleshooting

I have a nexus 5 rooted with stock rom and kernel and stock recovery+ xposed+GravityBox and some other xposed modules.
this happened sunday and again today.
I unlocked the screen and then the screen looked like that:
even on reboot the screen still was with the pixel snow
and after a few minutes of locking and unlocking repeatedly the screen turned OK again.
couldn't find a lot of information online.
does anyone knows why has this happened?
has someone experienced this kind of failure?
any advice?
thanks.

It's a hardware failure. Most probably the screen or the Flex cable went bad. It can only be solved by replacing it.

Definitely a hardware fault.... Had exactly the same screen on my n86 when the repair guyz told me that flex cable was damaged...

thanks..
the problem is I bought the phone on ebay and had it sent to my uncle who was in the states for a business trip and then he brought it to me when he finished his trip.
I'm not from the US so I don't know who should I complain to :\
sending it back to the US and **** will take a lot of time and probably money

Totally depends on the device's IMEI. If the IMEI if not of the country you're residing in, warranty goes out of the window. In any case, you need to send it in to get it fixed whether it's under warranty or not.
Good Luck :good:

Changing the flex cable won't cost alot...
If the screen is damaged (i hope its not) it will hurt...
So best is to get it done from local lg service center ..as u have no warranty by any means

[Q] Busted Motherboard

Hey guys,
Couple of weeks back, my Nexus died one me (after a few days of power button problems). I was hoping it was just the button circuits that had gone, but after speaking to a few local repair guys, apparently the motherboard is busted. I'm using an i9020T in India (only the i9023 parts are available here), and I'm not sure how financially viable it would be to send the handset back to America to get it repaired.
Any suggestions on what to do? Does anyone have a spare motherboard that I can buy? or is there any way to repurpose the parts and use them for something else.
Its only 13 months old, and everything else is in perfect condition, and I would feel really bad to throw it away as it is.
Any suggestions?

Same thing happened to me and they ordered a motherboard from banglore or something just ask the samsung authorized repair shops.
Was yours the i9020t or the i9023? I asked samsung repair here, and they said they won't repair the phone here. It needs to be sent back to america...
I actually just got my i9020T back a couple days ago from Square Trade for the exact same problem (good thing I got Square Trade). Power button stopped working, but the phone never stopped. When I got the phone back they said they had to replace the motherboard because it was bad.
The repair shop that Square Trade sent my Nexus S to is called CF Repair http://www.cfrepaircenter.com/ -you might want to give them a call or e-mail them to see if they can send you a motherboard or at least see what their advice to you is

Ah thanks I've just emailed them. Lets hope for a positive response ...
Hi Nikhil,
Any updates on this? I have the 9023, and pretty much the same problem. Power button problems, and then a dead set after a week. The service centre is quoting INR 9k for the motherboard replacement, damn!
Sigh, would hate to bury this.

Exact same thing happened with my 9023. Ya the service center quotes INR 8K to replace motherboard. Did you get it fixed? Shame that this phone just lasted for 16-17 months.
Hi, I also need a replacement motherboard.. any hints on where to order a new one?

Mine's still lying unnoticed. The number of people with the same issue is disturbing. Any leads?
My power button is starting to fail on me today, does it mean my motherboard is somehow getting messed up too?

My phone is going home. :(

The power button decided it doesn't want to work anymore. Since its been rooted, and I don't trust the shops in town, it's going back to HTC for repairs. They told me it will get wiped during the service (and I will do a factory reset before it leaves), what are the chances of it coming back locked with the factory ROM installed?
Any other things, besides the S3, I should watch for when it comes back? I'm not worried about losing LeeDroid, it's all backed up, and can be restored as soon as it comes home.
Well the power button is a part of the removable SIM cover so unless it's the button in turn being pressed by that that's causing your problem then it's a very easy repair... All bets are of as to whether they'll also RUU your phone for you.

The switch itself is on the phone. Only the physically pressable part is on the SIM cover.
I don't think you will get a s3 version back given the fact that you sent out s4 version and this repair should not be so difficult that they have to give you a replacement.
But, they will very likely factory reset your phone and put everything back to "out of box status". So you will have stock Rom, locked bootloader. I learned this from other threads where people saying it is part of HTC's repair process to flash everything to factory state no matter it's hardware or software repair.

Got the quote back on the repair today.
In order to properly repair your device, the following action(s) will need to be taken which will require payment due to the out of warranty diagnosis:
• Replace Device Main Board

So, when it comes back, it will probably be locked and untampered. It's bad that the guys at T-mobile were telling me to lose it, but I wanted to take the high road and do it right. A main board is $240, btw.

So not worth it...It will be $240 + tax.
You can buy a new one locally for ~$350...Probably could sell the other sucker to some idiot desperate for a deal for $200 as well...
Did they give you any reason why exchanging the mobo is out of warranty? You should ask so if not.
I mean, you sent it in because of a defective power-on button...
They'll just say the reason why is because the HBOOT displays "unlocked".
Honestly if you want to get warranty coverage on an unlocked phone in Europe your best bet is to brick it to QHUSB_DLOAD mode and then send it in.

That was exactly the reason I got. Oh well, it's on it's way back, I can finally put the Nokia 7510 I have been using out of its misery (and mine), and have my One back. There is at least a thread now, in case someone else runs into this problem, they will know what to expect.
I took my tmobile one s back with me to taiwan and got the screen fixed there (HTC has repair/service centers there, it's kinda like an apple store without the products, all they do is help you with your phone)
Anyways, they called me and said, literally, "the mainboad is unstable and needs to be changed" (i sent it in for a cracked lcd) I declined and said just fix the screen....they ended up sending me a brand new/refurb device..

[Q] Nexus 5 - no signal after water damage!

Hi! My Nexus 5 got water damaged during a hiking trip. When I came home I disassembled and reassembled it, and it started working. However, what I found out was that the phone got no signal to the cellular network. The carrier name shows up, and when I boot the phone, it ask me for PIN-code (which is accepted). When I go into settings where I can select which carrier I wan't to use, it shows all the carriers available, but I can not connect to any of them. Hope you understand my problem and thank you for all help
PS: Also, NFC does not work.

Or just buy a new cover for 25$ with NFC antenna ...
try reassembling the antennas or replacing them they are kinda fragile if you bent em'
MAYBE your in for a 100$ but it's worth tring it last time I check 16gb was still 350$ why not save one if everything else is working but two servicable glitches?
Edit: btw. warranty was void the moment it got soaked before the dissasembly/re part!
When it comes to water damage...and something doesn't work after....to me its not worth messing with. You may have other issues you've yet to discover as well.
Time for a new phone. Why spend a bunch of cash just to end up realizing its a lost cost.
Just me 2 cents. ?
Think I'll just buy a new phone. When I turn my phone off, it won't boot up again until I de and reassemble it again. Strange... Thanks for all help

Samsung Repair Service wants $300?!

Hello guys. I've sold my note 4 and got a used Galaxy S6, phone had couple of scratches and was in a really good condition. I used it for a month until... I woke up, my battery was at 60-70% but I was going out soon so I plugged it in and my phone started flashing screen white, and I quickly unplugged it. I tried blowing into USB port and it didn't work. Then I plugged it in again and my phone started rebooting randomly and touch buttons stopped working and flashing. Later I took it to official Samsung repair center and they sent It to like a Full/main repair service place. And after a week I got a call from them that they need to replace whole motherboard(which works fine, just USB board is fried) and they said that this phone had modified software and I need to pay 280-320$ to get it fixed.
What's even more funny is that I didn't even root it yet! I paid like 50$ less for the phone with a box and a purchase document. Also the phone is still on warranty until august. What do I do guys?
PS: I always used original USB cable and charger.

If they checked the KNOX bit and it is flipped, then the device is out of warranty. No amount of arguing will change that. Also the warranty doesn't cover devices that have been resold. (Found out that the hard way:crying
You can always go to Samsung Parts to find the piece you need.

Yeah. Unfortunately. I have a non authorised repair service in my city. So I guess I'll take it there, and pay like 80-120$. Better than 300$. I gave them a couple of things to repair before, and they were really good and quick. Samsung dissapointed me once again. Thanks for reply.

Assuming that knox was tripped by previous owner, you really can't fault samsung for rejecting your warranty claim. You knew the risks in buying phones used (as with any secondhand electronics), the previous owner could have tweaked voltage, messed up and sold it. Not trying to upset you, but it is what it is.
Upside is, you no longer have to worry about tripping knox. Flash custom roms as your heart desires. Good luck getting your phone repaired.

Random Screen Shut-Off

Hello Everyone, I am Extremely new to posting on XDA so I am not sure if there is a standard or not. Basically The Problem I am having is that the Screen randomly turns black and does not turn back on unless connected to the charger for about a minute. I know that the phone does not die as both the digitizer and speaker continue to function. I have Tried:
-Software Initialization in SmartSwitch
-Factory Reset in Settings
-Factory Reset through Recovery Menu
-Odin reset Image 5.1.1 and 6.0.1
I also can not turn it into the Samsung Service Center as I already replaced the back of the phone in attempt to reseat the lcd/digitizer cable. If Anyone has any experience or insight into this I would fully Appreciate it. Thank You.

Does your phone function 100% as designed (i.e. are you able to use your phone) while it is turned on or does your phone gets frozen?
Is your phone still under warranty? If your phone is still under warrant call or online chat with support and get a shipping label and send it for repairs. There is no need to inform the support about what happen to your phone before. If support determines that your warranty is void they will provide a quote to repair your phone. Also you can dispute the claim that your warranty is void. If you decide not to repair the phone they will ship it back to you for free. So you have nothing to lose but a lot to gain by send your phone for repairs under warrant.
I observe that many members post questions but seems to bee too busy don't care to provide an update in this forum once the issue is resolved. Hence kindly update us of your progress as it will expand our collective knowledge.
This seems to be a common problem and it a known main board defect. I have a similar issue and I have to send for repair after I return to the US from my vacation.

Okay so I retried updating it without a reset within smartswitch and so far it hasn't turned off. Also If I did want to Ship the Phone, Will they accept warranty if there is a small crack in the bottom right of the back glass. BTW Thanks you for the reply.

In my opinion that should not void warranty (not a water damage - you could always claim that you're phone fell).
As I said if the repairs are not covered under warranty they will give you a ridiculousness high quote to repair it out of warranty and you could decline and they will ship it back to you at no cost to you. So on the downside you have nothing to lose and you will get back your phone as is but on the upside you might get lucky and get it fixed for fee

Ok so they had my phone since Friday, but said they received it Monday. I found out today that the back glass did cause it to not be in warranty. Fortunately, they have already sent it back to me and it should be back tomorrow. Hopefully they tried some software trick and it fixed it. Fingers crossed!
Ok so They gave me a free box with some packaging(samsung). Looks like they didn't even touch the phone as it was not factory reset.
