Well I have been a owner of a LG Nexus 5 for the past (almost) 2 years now, in fact I am coming to the end of my contract very soon and will be able to either goto another company or get a new phone.
Anyways, sometime ago I experienced a problem with my microphone and external speakers not working, or at at least some of the time... After a bit of research online I found out my problem was related to a connection inside the phone that connected the bottom assembly to the main board at the top of the phone. It required me to remove the back panel and a few screws to remove the plastic cover, but the poster suggested putting some tape on top of that connection to hold it down more firmly to the socket it connected too. So I did this. I put some black tap (electrical tape cut to fit.) on top and then assembled the phone again. Viola, It worked!
Well, a short time after I decided that I wanted to update my phone from stock kitkat (4.4.4). Always been curious about custom ROMs and gave Cyanogenmod a try. Not only that I got bold and tried the nightly releases of the new marshmellow update. After some time I started experiencing things not working, like the camera, and a lot of freezing, hang ups and random reboots (not so much the reboots as the constant freezing). Often I couldn't get anything on the screen or the phone to respond from a locked state and when I did, often the phone would lag so much, that doing anything would take a long time and proved to be impossible.
I started thinking it was the nightly releases as the source of my problem and just kind of shrugged it off and figured "they will eventually fix the problem". I kept this thinking for quite some time. But it occurred too me one day that something else was causing the issue I was facing for the simple fact that the lag started showing up in the recovery mode (also custom) and a lot of times would continue to show up after I rebooted my phone. Hence, would rule out any 'software' issues I was facing.
I began to think that my problem was hardware. Maybe it was just time for a new phone. But still months away from the end of my contract, this meant I would have to pay off the 'problematic' phone first before getting a new one. I really didn't like that idea. So while looking into this problem, in a last ditch effort, I opened my phone again. Dunno why but I also decided to get rid of the tap on the connection I tried to fix before... I popped off the connection there and had a look at it. It didn't seem damaged in any way nor did the socket. Strange as it was I put that connect back in the socket and put the cover plate back on making sure not to torque the screws and assembled everything back up....
Now the mic and ext speakers work just fine and the phone is working like I just opened the box and took it out for the first time. And I have not once seen any problems... I understand what's happening here... still just wanted to share that for it was definitely weird or what?

Sorry about the link, only way I can upload an image.
Just so there is no confusion... an image of the effected area, inside the phone. The arrow points to the connector and more importantly the area of the connector that seems damaged. If I press lightly where the arrow is pointing on this image, the assemable at the bottom (speaker/mic) will work, indicating a loose connection. Although after visual inspection, I cannot see any damage to connector or the socket. I suppose the only way to really "fix" the issue is to order a new part. As stated previously, already tried tape on the socket to help hold it down, but that seem to cause just as many issues with the phone performance. Any other suggestions?
When ordering a replacement part, you need to be careful because there was another XDA member replaced the same part with a cheap 3rd party solution and the phone would not charge until he replaced it with an oem part.

Does anyone else have issues with there ext. speaker and mic not working?
An update on the phone;
back to square one. My ext speaker and mic will not work. And that socket has something to do with the LCD connection on the screen as it will black out if just the right area on the back of the phone is pressed. Only way to revive the phone is to long-press the power button for a reboot. Then will come up fine but speaker and mic still do not work.

Wow, that sounds pretty low level tactics of LG... just shameful really, but not hard to believe these days...
Quite honestly, I am just going to replace the phone. Think I got a pretty good run out of it and think its pretty well time for an upgrade. Anyway, for the reason I got the phone, it wont matter the speaker and mic don't work. Just going to use it for development and it will be a good test device.
Oh an this post is related to this thread so I thought I would link it for it may help someone else facing similar problems....

I'm not sure that LG had anything to do with the low-quality replacement parts.
If I were you, look for a n5 with a smashed screen that is suitable for parts.

Good idea, except the iphone is the most popular phone around here ... find it pretty hard to find one, been looking. But thanks.
I have seen quite a few busted n5 phones in Toronto. I have managed to get working phones with a smashed screen for as little as $30 which is rare for Toronto. Average I pay is $40 to $50. For this price, I either use the phone for parts in several phones or I get third part screen from Aliexpress for around $40 CAD.
I just want to update this as well...
I am fairly certain (now thinking about causes) its not really a design flaw, but more so because I frequently sat on my phone when it was in my back pocket...

It was not me but I had that same experience. Replaced with a cheap oem and it didn't charge after that.
I found out why. The charger usb socket was not connected to anything ! Unbelievable! It lacked the black plastic backing for that part of the cable to connect to.
Hey everyone,
recently my SC-02h (Jap Docomo version) hard-bricked and has no way to recover besides JTAG or motherboard replacement.
This made me think of an experiment.
Can you replace any motherboard (which includes all chips and the storage) with another.
I ordered the g935FD dual sim version with the Exynos chip, this compared to my QC single sim version which is currently bricked.
Hopefully within the next few days I'll receive the motherboard and start the replacement process (I will probable film it) to see if it works.
If so, anyone could replace their motherboard by a new one that is unlocked or has a different chipset.
Please discuss here if you're also interested in changing your own mobo with another.
Can't see why it won't work as the motherboard is what determines the model. Just make sure you order up a dual SIM tray too.
Motherboards from different chipsets *may* have different connections on how things wire up. I'm not saying they do, I'm just thinking out loud. I'd only buy a replacement motherboard from the same variant.
And good luck finding a new motherboard. At the price they sell for, you'd be better off buying a whole new phone.
Would like to see how this goes. Please record the process.

Yea I ordered that one, although I thought the tray looks the same (bottom part), so until my new one arrives I'll use the older one.

I checked the connections and they are the same, the only thing that differs is the sim holder and the chipset.
Also a new phone (unlocked) costs at least 2,5times more (live in Japan).

I'll record it on video as soon as it arrives, also the process of taking it out and replacing it completely. So if it ends up in failure you can all see it.
In what way is it bricked? The S7 is almost impossible to brick.

Hmm I flashed a rom with TWRP, (lineage, but wrong build) after that I rebooted and the phone stopped responding completely.
So black screen, no led when charging, no response at all when pressing buttons.
Even disconnecting battery and reconnecting didn't work.
Also no recognition in windows when connected to USB

Another thing you might lose is waterproofness. I cracked my screen badly and instead of repairing it at a 3rd party shop, I sold it and got a new one. Coz it won't be waterproof anymore..

i should be fine, just get it glued back together properly.
besides i don't really care about it.
Unless the other components (camera, vibrator motor, various sensors, OLED Panel etc.) don't differ in the way they talk to the mainboard, I don't see why it shouldn't work. As others have said, I'd really love to see how it'll work out for you. So, thanks for sharing =)
Well it didn't work out, I put in the new motherboard but the phone didn't power on at all. There is also no led when trying to charge it. I'll be sending it back to the supplier and buy another version instead.

Can you share the link of where you bought the motherboard? It might be that you bought a blank motherboard. In that case you want it to be flashed with the correct IMEI and partition (table?). AFAIK the IMEI has to be that of your previous phone since you can't just "create" a new IMEI. Don't even want to get into the legal repercussions but here's a sneak peak; in some countries it's a criminal offence to alter an IMEI or even have tools to alter IMEI. Don't quote me on this and I'm asking the community to correct me. If the motherboard comes from a previously active device, it should have its own IMEI and none of what I said before matters.
Whatever, none of that necessarily explain why it didn't boot up. Have you tried charging and plugging it to a PC? If it isn't dead, your PC should at least detect A device.

It should be one with an IMEI how else can it be unlocked.
I tried plugging it in as well, but my PC doesn't recognise it at all.
I've ordered a different one this time, this motherboard was also slightly different from the one I had (2 cables instead of 3) so it might be incompatible.
I ordered this one now: https://www.aliexpress.com/snapshot/0.html?orderId=82116420384467&productId=32737224430
Did you end up having any luck with the second motherboard?
Or has anyone else attempted this before?
I'm looking to swap my qc chip for the exynos.
How was the operation??
Hello i'm interested to know how was the experiment becouse i wanna try almost the same thing, i have a s7 sm935fd and i wanna change the motherboard for a sm935f model. Please answer me!
I am also going to try swapping motherboards. How did yours work out?
Hi @totalvamp,
I am going to try swapping out a good motherboard from a banged up sprint G930P phone with a clean IMEI into a clean, whole, G930X demo model that I picked up cheap on Ebay.
The "X" demo phones work on WIFI only. I understand that the "X" motherboards are missing the cellular radios, which is why I am trying this swap -- it should be far easier and less costly than doing a full screen&LCD replacement, which requires tearing down the entire phone, and costs about $150. Hopefullly, I will just have to remove the back, the QI receiver and I think the camera, and I'll get access to the motherboard.
My hope is that all the rest of the parts are present -- we'll see how it goes.
I look forward to hearing from you.
Philip
Let me preface by saying I have read the 4 page thread & nothing there seems to help.
I bought a Pixel late last year as gift for my mother as a Christmas present. Unfortunately, after resetting the device, I found that the phone had microphone issues - working for about an hour after the phone had been booted, then cutting out, taking the loud speaker, vibration motor and auxilary jack with. Much more recently, I have noticed that the loud speaker will now work, but the phone will not pick up an auxiliary input anymore, nor will the microphone work at all or the vibration motor.
From what I've read on here, Google seems to have fixed this issue in all phones built from January 2017 onwards but I am unable to find anyone selling the latest revision of this board online - I'm currently contemplating taking this into a Carphone Warehouse store to send it off (as they are an official Google repair centre), but I don't want to pay over the odds for something I know only takes 10 minutes to do.
My question is: has anyone had similar issues & fixed them? Was the problem the charging port PCB, or was it something on the main motherboard?
Also, does anyone know of anywhere that has stock of post-Jan 2017 boards, or even have a working spare themselves that they are willing to sell? I'm wearing pretty thin with this at the moment & would love some advice.
Thanks!
What is your phone serial number? Mine starts from FA6CL... No problem's here... at the moment.

I have the same issue and got fixed by replacing something on the motherboard. the engineer said is something from Qualcomm. I guess it is Qualcomm WCD9335.
The total cost is around $30

Have you disassembled the phone yet? One of the antenna cables could have come loose, they're pretty fiddly and pop out sometimes when the phone is dropped.
I'm pretty sure the antenna for both WiFi & cellular is on the daughter board as both the antenna cables connect from the daughter board to the motherboard so I would assume a loose connection would be the issue, but if neither side of the cable are loose, then it's probably going to be damage to the daughter board or a software issue - I'd attempt a software wipe first, just in case.
Thanks buddy

I bought a Pixel with a broken screen late last year & my intentions were to replace the screen and gift the phone to my mother as a Christmas present. Unfortunately, after replacing the screen and resetting the device, I found that the phone had microphone issues so I opened it up again, replaced the lower PCB with a spare I had lying around... same issue, only this time the microphone works if there's no pressure on the screen (eg. it's connected, but not stuck down?). Both these boards were built on the same day, within 2 minutes of each other (June 2016) so I can only assume that both boards have the common microphone issue of pre-2017 built OG Pixels.
After being unsuccessful thus far, I went online purchased another board (with a 12 month warranty), fitted this & low and behold it's got the same issue. The new board was built in May 2016 and seems to be a completely different revision as it looks quite different to both of the other boards in my possession (no antenna clips, different smd's, different spring design & minus 1 spring).
From what I've read on here, Google seems to have fixed this issue in all phones built from January 2017 onwards but I am unable to find anyone selling the latest revision of this board online - I'm currently contemplating taking this into a Carphone Warehouse store to send it off (as they are an official Google repair centre), but I don't want to pay over the odds for something I know only takes 10 minutes to do.

PM'd
Update: I contacted Google's authorised repairers.
Carphone Warehouse will fix the issue for the extortionate price of £169.99 (over half the price of a new one) & "SBE" have effectively said that they will not attempt repairs on devices that are outside of their warranty period, so basically, they won't fix Pixels at all (as they don't fix in-warranty devices).
Update #2:
After contacting Google again to say that their repairers wouldn't repair the device/repair it for a reasonable price, the support agent said the phone may still be in warranty & organised an RMA - the phone was returned to Google & replaced with a "refurbished" warranty version, which actually looks brand new! The even better news is that the phone isn't locked to EE, so a custom rom is being dumped on it as I type this!

May i acquire his contact details as well? With the taobao store link too.
This will definitely fix the microphone problem right?
Since this thread was started, a lot has happened in the Pixel world including a lawsuit over this very issue.
Can anyone else confirm that replacing the Audio Codec (Qualcomm WCD9335) will fix the microphone issue?

I tried to replace the audio codec with a local phone repair shop, it resulted in the phone not powering at all, the guy told me that under the audio codec there is some other lines on the board that were effected during the replacement, since then I'm trying to buy a motherboard to get my phone working again. No luck tho, I bought another pixel already and lost that one, so be careful.

I have a backup Verizon LG Velvet. I have the LG V60 as my main phone. With or without a sim the Velvet states "Service Disabled" and the bars have a small x next to them. I and Verizon have tried all the normal troubleshooting tips available.
Factory reset
Airplane mode on/off
Network reset and so on.
The sim works fine in other phones I tested so it's not the sim giving the issue.
Verizon tried on their end to get the phone to work but still kept getting the same service disabled. I'm down to thinking it's more a hardware issue than it is software. But not sure which internal module I should replace. The logic board or the lower PCB.
I even tried to lookup flashing the stock firmware to see if that helps via LGUP and LG Flash Tool. Neither I could get to work to achieve that goal.
Anyway, I was wondering if anyone could share an assist as to what is wrong or how to rectify the issue to the get the service to work on this phone. Anyone have any idea? Thanks.
Maybe the C port pcb. I know on Samsung phones one of the failure modes with the C port pcb is lose of internet and phone. It gets a lot of wear and tear. If it applies to this phone, don't know.
An experienced repair tech is probably your best shot...

They are generally inexpensive. Of course the elephant in the room is it could be the mobo instead... I hope it's the former.
It's also possible that the firmware was corrupted. A freak random hit by a high energy particle can do exactly that. A reflash of the stock rom be the next thing to try after the port pcb or maybe before depending on what you think.

I may have found my issue. I put the logic board under my scope and found some damage to the lower PCB like I thought and you mentioned. There is a "+" and "-" connectors above the charging port where the plate of the speaker connects to. The "+" connector is missing.
I ordered another charging port PCB and when that arrives, I will see if that fixes the issue and let you know.

So as it turns out, it wasn't just the lower pcb. Although it did need replacement as well. But it was the main pcb. So I ordered the main pcb from eBay for 60 dollars and the seller ended up sending me the entire phone in perfect condition and perfect working condition. LOL-go figure.

Go to system settings>display, see if you have a setting called "Accidental Touch Protection" and if it is enabled. That feature could be activating and then freezing the screen when you try to turn it back on.

Yeah, that would solve any software issues. If there is still a problem after that, maybe hardware damage?

Can't think of hardware damage cause then it will be permanently it only happens sometimes when screen is locked.
Need to know where to download proper and original software?

Google search for:
"Return to stock (your specific model number)"
That should find links to firmware, software tools and guides.

Hi there! What was the answer or Solution by technicians? Did they solved the problem?
Hi all there! As I see this issue is the same that A52 has. It's a typical factory problem that could be solved charging the main flex. That's the definitive Solution !
I have the same problem with my A72 (A725f)XID
Any solutions
I tried downgrading it didn't help
Changing the screen of flex also doesn't help
So it's a software problem
But any solutions???
I have the same problem. It seems that all A72 series are affected by this problem. The flex cable appears to be problematic. Almost every Samsung product I purchased had issues. So, never again Samsung.
Sorry for late reply for all questions above. My A72 was not even a year old it was sended to numerous shops from Samsung to the cheap Pakistani shops and it is Un repairable they said that there might Me a chance to repair it if I replace the main board but to find one is very scarce and a new one is almost the price of a new device.
To me personally I will never get a Samsung again my next upgrade will be Huawei,Google pixel or a Xiaomi or anything else I do think that the better devices like Samsung galaxy S22,S21FE and Z fold won't have problems like the A72 or A52 or there was just a big bach of manufacturing that went wrong.
But do let me know if you guys got it fixed in any way maybe I can have a try to fix mine then but to replace part for part and hope that it will be fixed is a expensive route to go.
No just make sure your next samsung is from the European or North /South american market
Then you won't have no issues
I use The A53 & A52s 5G now & i don't have problems

I ordered a new main flat cable, and it was supposed to be delivered yesterday, but stupid NordPost in Norway did not deliver it in time. So, I must wait until Monday or Tuesday to get it. Basically, my phone has been opened and lying since Wednesday. I will update you, when I replace the cable. In any case, original main cable in Norway is very inexpensive. It cost me 110 nok or 11 euros.

My A72 is from Europe. It seems it doesn't matter where it's from. All A72 models are effected with this problem.

You are lucky it is not expensive here in South Africa every thing is expensive if I take a guess it will be around R400, my phone acted actually weird because it started to have unresponsive screen restarted the device then will work for a few seconds then will have the same problem, sometimes my network signal will totally disappear and there will be two round sircles, sometimes when I charge my device it will show the phone is overheating even though the device was not even on for a while other times it will show the charging port is wet I can't think that the flex cable will cause all that problems
