Hi everyone, I'm have an issue with my Nexus 5 and hoping someone here can tell me whats going on.
It started off with the sound always cutting out, and I have to press the back part near the "S" logo for it to return.
Eventually the screen would go black but I can clearly see a back light is on. Now not only does the sound cut out, and screen goes blank.
It has become very sluggish to reboot it. I hold the power button until the phone reboots "Google" logo appears and the android animation. Now during this time the phone will be so slow to the point of being crippled out and i have to reboot it again and again until it is normal speed returns. Often it will black out during this time.
I'm just trying to understand what is failing. I tried safe-mode and it still has the issue. I cleared cache, reset the phone everything, nothing appears to fix the issue at all.
edit: I forgot to add, when I'm on YT or listening to music or browsing the web, even though the screen is blank with just the back light on, the sound is still going (when it works). I get text/call notifications still during this time.
My Phone Details.
Nexus 5
Android version, 6.0.1 (MOB30Y)
no ROOT
No replies at all, I guess I may have to garbage the phone. Idk what else to do with this device to fix it.
Please don't throw it away.
You said that pushing at a specific spot fixes the problem (or improves the audio situation). This means that it's a hardware problem. I have disassembled it many times and I know the layout. Behind the 'S' of NEXUS is actually the motherboard cover, and under it are 2 connectors; one for the battery and one for an extra 'board' that is located right underneath the LG logo on your back cover. On that 'board' is your screen connector, and also the speaker rests on there, as well as the primary microphone, 3G and 4G antennas and of course the USB port. The connector for this extra board is actually located a bit to the left on the 'S' (when you look at your phone from the back, it's more below the camera).
Now I have to note this: While using my phone, I have experienced some UI hiccups. At random times (very rarely) everything would just freeze for a few minutes, though music would still play. The power button was useless apart from the hard reset, it was so badly stuck. This was a software problem, although it appeared MOST at one point when my motherboard was faulty. Since I got a new device, it happened again but only once. I'm not sure that this is what you are experiencing. If this is the case, then it's a software fault. Never happened on CM so you can give it a try.
But since it's probably a hardware problem, you can always check it out yourself. Obviously if you have warranty you are covered. Otherwise, you can try disassembling it, at least take the back cover and the motherboard cover off, it's ridiculously easy, there is a disassembly guide from ifixit (I think) online, just be careful not to break the clips of the back cover (xp talking). If you open it, keep away metal things and the first thing you do after you remove the motherboard cover is remove the battery (xp talking again). Obviously turn off the phone properly before you attempt anything. Everything is sensitive in there so be careful. What you should look for is the long connector that connects the extra board that is located at the bottom of the phone with the motherboard. That's what you are pushing so if it's not sitting correctly, then that's your problem.
Plus, everything in there, apart from the motherboard, is cheap and can be found on eBay so don't worry if something is broken (unless it's the motherboard, then no hope ).
I hope I helped.
Firstly thanks for the reply. I did manage to remove the back and get to the connector you were saying. I reseated this and noticed the phone was working much better. I noticed the following still.
When it starts acting slow/crippled pressing this connector fixes the issue. However once the screen goes black with just a backlight this method is rendered useless. Also sometimes when I plug in the wire to charge it will cripple and or go black. So I wondering if the board is shot as you suggested to order a new one, or is it the connector strip ?
Again thank you for the response.
It seems like this board is causing everything. First, check the connector on the motherboard. Make sure that nothing is wrong on the motherboard. Then you can remove the bottom black plastic thing that has the speaker on it and 2 antennas. Then, inspect this board. Check the connector of the display. There is only one big connector on it. This board is glued on the frame of the phone. You can remove it but do it carefully. Do it slowly so that you don't break it. First, remove the antennas extension cables from either this board or the motherboard, and then pull it out.
This board is definately responsible for the black screens and audio issues (unless your display is faulty, check its connector), but I'm not sure about the phone being sluggish. Since this board offers input to the motherboard, I suppose that it could be its fault.
Remove it and inspect everything. Then, if you want, you can order a new one. If you come across D820 and D821 models, I don't think that this part of the phone has anything to do with it so don't worry.
I will take a further look into this for sure, and report back. If you can provide which motherboard is required for my device, so I can also read into this and so that I may order it right-away. Is there any model number or something that indicates which board to order once it is open?
Thanks again!

You don't need to change the motherboard, not to mention it's very expensive and hard to find. What you need to replace is probably the flex cable that goes below the battery. For example this.
This is not model specific, you can use it with all available Nexus 5 models (D820/D821, 16/32GB) so it doesn't matter what device you have.
FYI, if you think that you should replace your motherboard (you probably shouldn't), you need to take into account the storage (16/32GB) and the network differences (D820 or D821, the only difference is about the 4G networking, the american version has some bands enabled and some others disabled, and vice versa)
Okay, I just ordered the replacement flex cable. It is going to take about a month before it arrives from HK , I hope it fixes the issues. I will respond to this post once it is here and installed. Thanks again.

in the meantime, pray it isn´t a motherboard issue, the conector can go bad and lose a few solder joints
I have exactly the same problem... I unmounted motherboard and clean everything but didn't help to much... did you find any solution ??
Siamer no solution just waiting for my delivery of the part. However it is getting worse with the blackscreens and crippled lag.

my is the same. sometimes is working for few hours without any problems and than starting again, on the biggining it was power button problem but not I don't even touch that button (I use vol button to turn on) and sometimes screen getting black (with backlight on) and can't do anything so have to reboot... it's so anoying! Hope that parts will fix it, please let me know if you will find some solution. Today I will open phone and clean all connections etc...
Thanks,
siamer
I believe the part may fix it. I noticed if i run my finger along the strip the phone may uncripple itself or just turn black all together. I'm hoping it fixes it. I will report asap but this HK shipping is so slow it will be a month. Also there is no tracking
ATM i'am just trying to becareful with it trying not to trigger the issue. I just did an OTA update using FlashFire (6.0.1 (MOB31E) i wish v.7 will be available for my Nexus 5 ha ha!
Also if the Nexus 7p arrives I may just buy it to replace this Nexus5.

Hi Omega59.
Today I bought air compressed can(name: air dust) and open my nexus 5 as much as I could. I clean everything, every connector, every cable etc. and last few hours is working fine... even power button is working ok. I will let you know in next few hours how it will be, hope will be still ok
Good luck!
siamer
[edit]
there is still same problem, working better than before, black screen not showing so often but still showing... I think tomorrow I will order oneplus3... Would be nice wait to see new nexus but how... :/
Yeah I'm not sure when the Nexus 7p will arrive, they not even advertised much. I will assume next year?
OnePlus 3 looks nice, but compared to Galaxy 7 it's a bit better slightly. You should check out comparison charts
Maybe they are making a OnePlus 4 soon.
oneplus 3 already ordered. I don't like samsung. I would say nexus "7p" or "pixel xl" will be launch october as always prabaly 4th of october - leaks saing that... next oneplus will be launch around july next year as I know. the only phone that I was thinking about was oneplus, htc10 or new nexus but can't wait to see nexus...
today by excident I broke screen in my nexus 5, got a little bit angry
Regards,
siamer

You probably don't want to hear this, but if it's getting worse, it's probably because of the pressure you apply to it, you make it worse. Be careful when you apply pressure around the motherboard since it's very sensitive. You REALLY don't want to break the motherboard. So if you find yourself pushing on the motherboard too often, you might want to leave it and wait for the replacement part so you won't ruin it.
Waiting for your news...
My part arrived yesterday. I put it in was pretty easy, however the first attempt i had to redo the top connector bc it was still black screen and no audio. After I disconnected the top connector ran some alcohol over it, re-put the top part things are working okay.
Just a note, the little USB connector (charger slot) seems to be very tight compared to the old one. Maybe bc it's new and not as worn down. But even just to put the wire in, requires more of a push, same with removing it.
I will see how it goes before I can really say that was the issue. I will report after a few days about it.

I don't think N7P will be out this year, they have not advertised anything and we are almost in Oct. Right now they are all rumors.

When I changed my screen and housing it was difficult to slide the USB connector in too. Just make sure that everything is in place, there is a rubber think for the microphone, maybe that's what's in the way. Don't stress the connector too much.

Firstly, my screen does not show visuals. I can still touch the screen and make things happen, but it is just a back-lighted black screen. I have answered calls on it and such. Basically I'm returning it and getting a new one.
Since I am getting a new one, I want to see if anyone ever heard of this problem and to see what the cause of it is, for prevention purposes.
I didn't get it wet (the white sticker in the back is still white.) Though I have flashed PROven ROM to it a couple months ago (it's a great ROM by the way), but could that have messed up my screen?
I also wanted to know since I can't see the screen, would I have to, for warranty purposes, (blindly) reflash to the Stock ROM?
Thanks in advance!
Yeah, you probably oughta return it to stock configuration (good luck on that!). If you're really lucky, that might even fix the problem. Have you done a hard reset yet? Might be worth a try, although it certainly sounds like a hardware problem.
Sounds like the flex cable has gone bad
Exactly same thing happened to me this Tuesday. Luckly I backed up info to memory card using PimBackupV2.8 with remote control software on my PC. With the remote contol tool, I could see everything as if on my phone and icons are clickable.
Hard reset did not fix the issue. I then flashed the shipped official ROM and stock SPL for warranty purpose. Will send the phone to them today for repair.
mine also like that..
from vodafone also..
the things that make me panics is the phone become hotter and hotter.

Summer is coming...
Sometimes they make updating phones too easy......
The back of my phone often gets hot I have to use the edges to hold it even though it was not a hot day and it is in my pocket.
blank screen
ya so my screen is blank white
but everything else works
i've heard something about this being a faulty "flex cable"
how can i fix this?
thanks so much for your help
how do i fix this???
did you eventually find out how to fix this/???
u ever end up fixing that? how?
thankss
Mine was still in warranty so I rang Vodafone. They sent me a special delivery envelop the following day. I sent it back to them. The following day I got a text message from them saying they got it and was working on it to fix the fault. The next day received another message saying the device was on the way back to me and I should receive it the following day.
Actually they sent me back a replacement
So.. basically.. is this a faulty flex thing?
I had the same problem for the last week until today i was about to buy another one since i dont have any warranty for this one.. I searched google and saw somebody say that just putting a business card between the keyboard and the lcd and then slide it and it works so far
hope it helps everybody
Ack! my Fuze, which I got off eBay a few months back, just went black too.
I'm not exactly sure whether it's the LCD or the flex cable, but the fact that the D-pad backlight also has become intermittent makes me think it's the cable.
So has anyone attempted the flex cable repair themselves? I see you can buy the cable for around $40 and the LCD for around $80 from Hong Kong.
Maybe this is a sign I should just get an Android device.

Did you end up fixing it? I have the same problem.
same thing happened to me Twice.... in my sleep overnight. I LOOOOOOOOVe my raphael but man this was the last straw
This maybe of some help for those of you with blank screens. I bought a Touch Pro on ebay that had a very dark screen, occasionally you could just make out some icons being displayed. Using Mymobiler showed that the basic system was working, as was the touchscreen. Other symptoms were that the camera would not work and the keypad lighting was intermittent. Sometimes on connection to Mymobiler a dialog box would come up saying there was an error with Microp?!?
Despite cleaning all internal connections and ensuring they were correctly and securely made the problem remained. I then noticed that the small camera used for video calls (in a socket on the main flex cable) looked very dirty and corroded. I removed the camera module and, using a fibreglass brush, cleaned the contacts on both the socket and the camera module. These were very badly corroded with verdigris.
On putting everything back together I was most surprised to find the screen was now working, as was the main camera. Unfortunately the ROM that is loaded doesn't seem to have any facility for checking the front video camera. There are still problems with sound - both the loudspeaker and the headphones seem to be dead and I have not had the opportunity to test GPS, Wifi, bluetooth, buttons, etc, however I will keep working on it.
Hope this is of help to someone.
I was upset, could not handle life anymore. I was at work and just threw my phone with tremendous force into the wall. Made hole in drywall but phone remained in tact. Nothing seemed broken.
I live in a 3G area but not it never displays the 3G icon, infact most of the time it displays the roaming icon. My calls are always getting dropped. The internet on the phone no longer works.
I tried to reset the phone, and did a rom update with a rom I found here. Did update successful but no luck. Then re did a rom update with the latest one from the HTC website.
Same problem persists. How can I know what component is damaged and where can I get the part to fix it?
When I had a HTC tilt, I sat on my phone and broke the screen, was able to get replacement unit and change it myself with ease.
I would like to thank you all in advanced and hope you all have a wonderful day.
Study here how to dismantle the device and what the components are
Dude, some therapy may help....got insurance, do that and get a replacement phone
having taken mine apart, if it looks like it's still in one piece, the thing that jumps immediately to mind is just that your antenna got loose. it's the only thing pretty much with an exposed connector that could pop off. (the display may be able to also, but you'd notice that =)
search for the raphael service manual, only tricky part in getting to the antenna is after you pop the back housing loose on the top 3 sides, you have to pull back the top far/hard enough that you think you're gonna break the usb port to get the housing free of it. Pull it back a bit, unplug that speaker wire, then pull it back some more, needs a gap at the top of about 2 inches to clear the bottom usb port. it'll just click and snap free. i took 30 minutes doing it cuz i thought i was gonna break it.
A friend of mine had a Galaxy S3 Amber with a broken (and blank) screen and wanted her data from it's internal memory that is locked and not in debugged mode. I did a lot of research and found the best, most efficient way was to do a motherboard swap with another gs3. I had a Galaxy S3 Blue. I watched a couple of videos and it seemed rather easy. I gathered the proper tools and was EXTREMELY careful not to break or rip anything (and to my knowledge i did not). When i put her motherboard from the amber one into the blue one and the screen would not come on. My first thoughts were it must be her motherboard that went bad. Well when i went to put my blue gs3 back together (again being very careful this entire time) I'm now having the same issue as she was. Black screen, no back light. The bottom lights DO come on and i feel it vibrate when i get a message. There was also no power on chime...
I know its hard to tell with out looking but any ideas on what could be wrong or what i might have screwed up? i checked all the connections and everything looks perfect. Nothing is bent or connected wrong and I didn't force or break anything.
update: so i found that the touch part of it still works fine. i can hear the ripple unlock as well as all the other sounds and such when i touch around and i can here it opening apps. the only issue lies in the screen itself being blank with no back light what so ever,
First of all remove the battery and attempt to power on, then leave without battery for 1 min, I know this sounds silly but it worked on an old iPhone 3G so anythings worth a shot.
If that doesn't work go back into the S3 and make sure all the data clips are firmly in place and locked down but not twisted in anyway. Also make sure their is no moisture or dust on the ribbons. You may not realise it but even the smallest imperfection with this can cause massive issues down the line.
If all else fails her phone may have broke your screen, I don't know how but it is a possibility
Hope I could help and good luck

so i took it apart again today to double check and clean everything and under inspection i noticed a teeny tiny slit on the edge of the lower, bigger ribbon. i know the smallest bit could be horrid. Any fix and would that cause just the screen to not show? i don't know if that is the led connection but i think it may be.

If theirs a slit I'm affraid that could be it for the screen, like I said even the smallest imperfection can cause massive issues. The slit is probably in the one of the data sections of the ribbon cable which is why data for the screen isn't being carried.
For the fix I don't think their is one unless you can fit a new ribbon on to yout S3's screen
Sorry about the screen
So I took it all apart again. Cleaned ever little thing I could and now it works again. ?

Hello!
I have a Nexus 5 with no warranty (according to LG, I need a receipt which I don't have) and the display is acting up. I noticed if I slightly bend the phone, the display flickers, sometimes fixes the problem, or it turns off. Over the last 6 months, the touch screen has been erratic and sometimes I have to hard reboot the phone to get it working again. Also on startup, sometimes I get the rainbow coloured "static noise" on the screen and then I push on the screen a bit and it is working again. Does anyone have any ideas what might be the cause and how to fix it? I feel like it's a ribbon cable problem but I have no clue. I went into Bootloader and factory reset it multiple times, pushed the factory image, pushed TWRP and Cataclysm.
Thanks for any and all help!

Replace the flex cable. It's fairly cheap.
If that doesn't solve your problem, then it's a screen or motherboard issue (i'd recommend paying LG for a repair rather than guessing between the two and possibly wasting money).

Thanks for the info. I have been looking for a while but I'm not sure which flex cable to replace? From the iFixIt teardown, it doesn't look like getting to the display cable is easy/possible. Do you have any links for what I should purchase? I'm comfortable with taking it apart and doing the work, just want to make sure I buy the right piece .
Thanks!

I've the same problem. atom bomb, did that work for you ? how did you end up fixing your phone ?
Title explains all. I'm in a tight bind with money too..
I want to believe I can just reflash stock via odin and it will come back. Or is there something else I can do to make this work?
It sense touch 10% of the time, but it's never enough to unlock my phone or do anything with it.
Edit: the new screen worked perfectly before I did the operation. Don't know what went wrong. I didn't scratch or bend anything to my knowledge. The process took about 10 minutes and went really smooth.

Hello, I repair cellphones for a living. And it depends on a lot of things. My guesses are three things. From most likely to least likely.
1. You said that everything was working fine before you changed ROMS, it could be an incompatibly issue between the screen and the software. A lot of aftermarket screens are mostly compatible with stock, a lot have compatibility with custom ROM. It could be an issue solely on the software and not related to the screen.
2. There isn't a solid connection on the LCD connector, that usually happens with during installation, sometimes if the device is set down hard or dropped knocking the connection loose.
3. It's a defective screen. It happens sometimes. It's not uncommon for a screen to appear fine but after a few hours it acts up. It could have just been a coincidence that you noticed or went defective when you flashed (not saying flashing is responsible for this scenario).
Flash back to stock and then you'll have a great chance of to see which out of the 3 are responsible. Cheers.
I repair iphones, android devices, laptops, ect.

There are only 2 flex cables on the S5 LCD. Make sure the primary (top flex) is seated correctly, then the easiest thing to check before taking the screen back off is the flex under the battery cover. You will see a little screw near the lower right of the battery with a little cover. Pull up that cover while the battery is out and make sure that cable is seated correctly. If both flex cables are seated correctly then it can only be 1 of 2 things IMHO, the screen you purchased is defective or you bent some pins on the mobo where the flex cables attach. I don't think it's a rom issue.
