Mic record loud hissing noise independent of Rom [H850] - LG G5 Questions & Answers

I have bought a used H850 that I can't return. Every time I record a video (haven't tested calling yet) I hear a loud hissing (with static crackling) on the recording later on. This happens on both Fulmics Rom and LineageOS, thus I think it is hardware related.
I applied the fix for the GPS from this video (open device and put folded paper under the board where the gps antennas are) and folded a paper to have three layers. Since I don't remember testing video before testing and fixing GPS (because it was broken), I don't know if that is related.
Anyone have an idea?

I also have on of those camera modules for the G5, which attaches to the lower end. I tested it, because it also contains a microphone. When I record with that module attached, the noise is still there, but muffled.

I removed the paper, but that did not get rid of the hissing sound.

So I tested calling and the noise is there, but stops a couple seconds into the call. I guess when the noise cancellation kicks in.

So I reverted back to stock using LG UP (Uppercut) and an older kdz file, then used to automatic update process to get the current rom.
And now the hissing is gone?!? It's great! But I bought this device to use with custom roms, especially LineageOS. So I will have to go back and see how that works out.

OK, now it gets weird. The first couple videos I recorded with the April update. Those were noise free. Then the auto updater applied the June update for the stock rom and the noise is back. On stock. If that is a software issue, how come I can't find anyone else with this problem? And if it's a hardware issue, why was it gone for a couple videos while I was on April?

[Q] No In-call audio. Suggestions?

Hello XDA!
First, some background: A few weeks ago, my phone went for a swim. I let it dry for a few days and turned it back on, but the phone wasn't very reliable (time would run slow, half the time I couldn't make calls, and the 3G wouldn't work at all). The touchscreen however was perfectly fine. So I found an eBay auction where it seemed like everything worked except the touchscreen. I bought it, and transplanted my touchscreen onto it.
Unfortunately, while most things work, I don't have any audio coming out of the front speaker, meaning I can't hear people when I call them or they call me, and if I call them, I can't hear the ringing that goes on before the person picks up. I read on some forums this was potentially a software issue, so I reflashed the latest RUU, and got nothing. I flashed KaosFroyo v24 and still have nothing.
My current work around is to wear my headphones all the time with it (which isn't TOO inconvenient, since I listen to Pandora a lot). The microphone works. The speakerphone works (since it goes through the speaker in the back).
Does anyone know if it's possible to transplant that speaker as well? It seems unlikely since I'm pretty sure it is attached to the motherboard...
Thanks!

[Q] Problem with microphone

Hello guys,
My problem I am experiencing is with the microphone that picks up sound for videos and voice recording. In calls, it is fine, as the gs2 has 2 seperate microphones? One for calls and other for videos/voice recording.
Anyway, the problem started around 2 months back, it then disappeared after blowing into the microphone hole at the bottom. Now recently, it randomly began to not work again, so the same old static/screetching when recording was present, it even started to not record anything at all so I tried to vaccume it to get dust out, and it then started to record static and very distorted audio.
I left it a day, and WALLA! works, but now it has gone back to not recording any audio at all...
I'm not sure if this is hardware or software related?
Any light to be shed on my problem/suggestions would be really great, its still under warranty as well by the way.
Regards,
Carlos
It sounds like it may be damaged. I'd send it back for repair/replacement.
Incidentally, the SGS2 does have 2 microphones, but one of them is used for noise cancellation. It uses the same mic for both calls and recording. If it's 100% fine for every single call, but bad on video/audio recording then it may be that the recording level is a lot louder than the usual in-call level, and that's why you're getting different results.
Incidentally...

Redmi Note 3 PRO (SD) No Sound/Audio

hi..just bought this phone about 2months, now i'm facing No sound/audio at all, here's some detail and if anyone of you any good hardware repair skills here, i need your help, as i believe100% it's not the software issues:
1. phonecall, on stock MIUI (NoROOT/customkernel,pure officialrom) its freeze/hang when dialling numbers - few second latter its rebooted itself. voice recording app won't work can't use the app as its error pop-up said, and sometimes i need to hard restart to use the phone again. and its gime bootloop and drained battery (4000mah cannot even survived for 7hour), even with no internet connections the battery still drain fast.
2. when someone calling me,there's no ringtones, even when i answering the call there's no sound at all, no musics sound, any audio files i play only hisssing/noise sounds i can hear just like feedback sound.
3. Unlocking Bootloader, replacing other rom the sounds completely disapear, no hissing,noise at all (CM,Mokee) and still phone app freeze/hang when i try make a phonecall,(reboot/hardreset)the only solution to make the phone back in usable state.
4. installing Citrus ROM, the sounds back but only hissing/noise sound on sometimes i can here the sound with some feedback issues. phone app works i can make a call without freeze/hang,no reboots, but i can't totally hear someone talk to me at all, but when i turn on the loudspeaker i can hear someone talk to me (with some annoying feedback sounds),
5. as i bricked it once and need to reach testpoint so i believe its not under warranty, seal already broken.
6.ordering the parts, connector charging board(which contain whole set new audio i guess hope can fix the issues, but just noticed that if that's part causing the no sound issues, its only fix the audio such as music,ringtones..not the front speaker(phone related still not repairable)
7. trying contact some friends which some understand about hardware told me, i break down the IC Audio so its imposible to repair/change that part since its directly micro-soldered to the mainboard.
anyone have same problem as mine?, or some of you have solutions for my problem please reply .thanks

Same problem as mine.
Even the video recording do not work too.
Is there any solution how to fix it?
I use it as ipa/od without ability to make / receives any phone call, so many ppl has the same problem here seems was Xiaomi's bad hardware components, which mine believes caused by sudden-removal audio/aux jack while its still playing the musics
anyone know the average price to fix the sound ic compared to the phone? maybe 10%, 25%, 50%, or above the price of the new units?
I have the same problem,, could any one tell me where I can buy the hardware (IC sound).
Plz tell me solution. My mobile mi note 3 audio problem, audio only listen Bluetooth.

Redmi NOTE3
I need audio IC for Redmi NOTE3 we're can I buy
hello.it is an old topic. i hope it be useful for anybody else. a few days ago My redmi note 3 pro kenzo was damaged by water. after that when I turned it on, logo of my custom ROM was appear and boot loop ... First I think it was for ROM or kernel. I installed another ROM with other kernels. I could turned on my phone and enter to user interface. but everything that was related to sound ( like : camera-music-call-headphone,... ) was not work at all. I searched a lot. I found out the problem is for Audio IC (WCD9306 Audio IC) this model. https://www.deviceparts.com/wcd9306-audio-ic-for-xiaomi-redmi-note-3-ori.html
it is used in Samsung mobile phone like S4. however you can buy it. but the main problem you can't change it by your own without tools . if you are familiar with hardware it could be useful: http://www.u2ugsm.com/blog/xiaomi-redmi-note-3-ringer-solution-jumper-problem-ways/
I think cleaning IC with cleaner or alcohol might be useful. good luck
Edit: After 4 hours I turned it on and sound is back! I just cleaned it by alcohol and cleaner. but I made mistake. a little bit of that alcohol-water liquid is entered in my LCD screen. I put it in warm place and hope it will get better.

**HELP NEEDED** Speakerphone/Microphone Issues :(

Hi Guys,
After almost ditching this phone recently due to several frustrations I recently took the plunge and installed [OFFICIAL][7.1.2] Resurrection Remix 5.8.5 with OMS by gwolfu.
So far it seems fantastic and I've managed to resolve the slow charging issue by updating the bootloader and modem to the 20V version and flashing the qc-typhon-h850-M6 kernel.
However my device is plagued by an issue where calling is virtually impossible, which is kind of an error seeing as the G5 is....ya know.....a phone.
When I try to make phone calls I can barely hear the person on the other end (i've checked the volume) and if I turn on the speakerphone they can no longer hear me. Even if I turn off speakerphone they can't hear me anymore after activating it.
Does anyone have any ideas how I could fix this?
It's literally driving me insane that there's such an amazing, smooth ROM which has extended my battery life something crazy but it's plagued by such an annoying issue.
Any help would be HUGELY appreciated
Bump?
I have a similar problem with LineAgeOS 14.1 on my H850 :/
I have a problem where mine doesnt work on the main mic, but as soon as I turned on speakerphone then the other person can hear me. Its very headache inducing because I use telegram and it uses the main mic therefore recording voice is useless. I literally took the plastic shell off of the part that everything with the charger, speaker, and mic is located and nothing blocking it.
I got the replacement module for the g5 and that still did not fix it. I dont know what to do.
EDIT: I just now found out that after taking out the motherboard, there was a red sticker covering some golden connectors, after taking that off fixed it. No idea why there was a red sticker there but please check and if it is there then take it off. itll be on the other side of the motherboard..

Question Microphone issues when talking from afar

I just bought an A52 5G and I'm experiencing some issues with the microphone when talking on speaker, e.g., video calls on WhatsApp or similar).
It looks like phone is always using the "regular" microphone with noise cancellation and never switches to those with the far field pickup. The result is that if I don't talk very close to the phone others can't hear me at all, hear cut offs, or a very muffled/metallic voice. I also tested this myself.
I tried testing the microphones on the audio loopback interface dialing *#0283# and selecting the two microphones to hear me back talking. They seem to both work as intended, but it's clear from there that the phone is always using RCV_1stMic (what looks like the microphone with noise cancellation used when talking with the phone close to the ears), and never switches to SPK_2ndMic (what looks like the microphone with the far field pickup). I'm pretty sure that the OS should switch automatically between the two depending on whether or not the speakers or on. I can't really find any option to set a "default" microphone or anything, and I'm not sure there should really be one at all.
At least, it doesn't look like an hardware problem to warrant return, but I'm a bit concerned that this might be something for which I need to wait for an OS update -- which might just never happen.
Anyone else experienced this issue?
I was about to return the phone when I received a new update whose version number is: A526BXXU1AUE1 / A526BOXM1AUE1 / A526BXXU1AUE1 -- security patch level May 1st 2021. This wasn't there a few days ago when I last checked for updates.
The link at the bottom of the "Last Update" screen points at https://doc.samsungmobile.com/SM-A526B/NEE/doc.html even though that seems to refer to different build numbers though: A526BXXU1AUD6 and A526BXXU1AUCA)
This seem to have fixed the issue on my side: now the far field pickup mic correctly activates when on speakers. Can you guys double-check the updates your phones and see what's your version?
I'm still running the April patch, but I've never had any microphone issues
