Help with heavy microphone static - Android Q&A, Help & Troubleshooting

My Verizon S8's microphone has recently developed heavy static and noise whenever making phone calls and voice recording. My voice is barely audible. This seems to have happened after upgrading to Pie. It was working perfectly fine before, and I didn't install any new apps. The only changes I made was upgrade to Pie and switch out my Google Fi sim card for the Verizon one. I tried rebooting in safe mode, wiping cache, restoring network settings and nothing has helped. Does anyone know a solution to this or know what could've caused this? Thanks in advance.

[HELP] Audio cuts out. No sound during phone calls.

So I recently just rooted my droid and I'm running the evileris firmware atm I'm really happy with everything except that my phone can no longer make phone calls. The sound during phone calls does not work and I think it may not work sometimes in the music player as well. It works when I plug in the headphones but when i take them out no sound.
Airplane mode and resetting do not fix this problem and the updates that I've tried flashing from [FIX] Audiofix. NEED TESTERS FOR NEW KERNEL in the Hero CDMA forum do not work either.
This phone worked fine before rooting and flashing and the problem is present on all the roms I've used. The update above simply hangs my phone at the bootscreen, no matter which one I use. (Maybe its written just for hero?)
Anyways I was hoping one of you guys could have a fix or maybe have also had this same problem? Thanks!
(from what I've read in the thread above it seems the issue is a bad kernel that hangs up or fails to reset so you have to do it manually, but resetting doesn't fix the issue for my. My problem is constant phone call audio loss)
UPDATE: I have done some more experimenting and it seems the only problem is from the in-cal speaker, because when I put speakerphone on it works fine. The problem lies with the front speaker (part that goes to your ear).
maybe your phone is broken?
I went back down to 1.5 root, works fine. Its an issue with 2.1 :/ So currently I have 2 nandroid backups, 1 of 1.5 and 1 of 2.1 so I'm just switching in between the two.
did you try....
Did you wipe before flashing? After flashing did you try *228 opt 1? This may help as it sorted my audio issues with another Rom.
im having this same problem and i have no clue why i have tried everything knows possible to fix this.
I wipe before each flash as well as each recovery haha. atm my setup is 2.1 evil eris for the weekends and 1.5root for the weekday when i actually need to make calls
*228 opt 1 did not work btw
I just make a new backup at the end of the week and recover to the other one, works like a dual-boot pc or a bootcamp mac. It works, but its getting kidna old I'd rather just have 2.1 for good haha.
Longtime lurker.....1st time poster....I just installed leak v2 (I was one of those that was too impatient to wait for root)...I had the same problem that everything worked fine except the phone had no in call sound. went through all the setting and found that TTY was set to full...I unchecked it and the sound came back. I know this may be simple...but it worked for me.

I'm having the same problem... During a phone call, I get no sound / can't hear the person I am calling from the "internal speakers" (i.e. the one you hold to your ear during a call). If I switch to external speakers (i.e. loudspeakers) I can hear the person I'm calling...
What is this "TTY" setting that fixed this problem for you? Where can I find it and uncheck it?

NO IN-CALL SOUND when I get calls or call myself

3 days ago I started experiencing weird phone behaviour. I tried calling someone but i didn't hear the "calling" beeping sound nor i could hear if there was any answer on the other end. Then i couldn't hear anything when i was getting calls. It didn't matter if i use the "loud" speaker or the "on-ear" speaker, the result was the same - no in-call volume. Microphone and "loud" speaker seem to work fine as i could use them as usual with other apps. Mobile data was working, so antenna was also OK, SIM card seemed to function properly as well. Other people who I tried speaking to did hear me fine, just i couldn't hear anything.
I tried freezing, then uninstalling all the non system apps that i thought could have impact on this matter, but that didn't help. I was using AOKP Rom and i had nand backup of Omega Rom 5.2 with stock samsung touchwiz, I tried restoring back to it, but for my surprise the in-call sound was still quiet. I didn't know what else could be and let it alone for an hour or so. Suddenly, the next time I tried it again, it WORKED!. After 2 hours of it working, i got back to my AOKP as i have it backed up right before switching to Omega Rom backup. I defrosted the apps and reinstalled the uninstalled ones. Nothing was influencing the in-call sound of the phone, everything worked fine.
The next day this problem popped up all of a sudden again. I got mad, i tried everything i did before except restoring the stock rom. Nothing helped. I then booted into CWM and set to fix permissions, to wipe Dalvik cache and i flashed the latest modem. Rebooted. The in-call sound was OK again. Something of these actions fixed it.
Today i got this NO IN-CALL SOUND bug once again. Seems like it wasn't the new modem that helped me. I booted to CWM and wiped Dalvik cache, rebooted, the in-call sound was working fine again. So, wiping Dalvik cache does fix the problem so far.
I'm keen to understand what exactly could cause this weird behaviour of disappearing in-call sound. Do you have any ideas?
I have the same problem.
If you find any sollutions, let me know.
You may delete some system apps.the solution is that you can just flash a rom and don't delete the apps you don't know
I've experienced something similar. I think in my case the MIC wasn't working either, but not entirely sure about that.
This thread seems to be about the same issue:
http://forum.xda-developers.com/showthread.php?t=1721604
Also while browsing the developer forum, I bumped into something interesting:
http://forum.xda-developers.com/showthread.php?t=1745974
This is for a ROM I don't use, but if the it's the same issue, and affects other ROMs too, I'd be very interested in knowing what exactly was fixed here.
Experienced this problem for the first time today, the volume actually disappeared during a call. Read through the posts suggested above and cleared cache and dalvik, but it didn't make any difference. Finally, I removed the battery, re-fitted and re-booted and it's currently working again. There does seem to be an issue with Omega/Siyah 1.2.6 combinations which is what I'm currently running

[Q] Microphone and Speakers not working!

Recently my phone has decided that it will allow me to call other phones but it won't let me hear the other person or speak to them. Every other voice activated application works and as do the speakers, it is only during phone calls. I have tried resetting the phone but the problem persists. I was using Omega v26 and have recently upgraded to v27. Does anyone have a solution, or know where to find the thread that deals with this problem? I have had a look, but there is always the chance that i missed something.
I restored an Omega V13 backup and the problem seems to have disappeared. I still have no idea what went wrong. I'll try reflashing one of the jelly bean roms and see if the problem returns.
Hey, i am currently having the same problem. i could hear the other person, but they cant hear me, and sometimes i cant hear them as well. but other voice apps such as viber and skype both can work. i recently tried to install Ressurection Remix but failed to boot, then i restored to the backup i put in place before. any help?

Call audio issues when dialing out

Hello everyone,
I have recently been experiencing a weird issue with making or receiving calls. About 20% of the time, I am able to successfully make and receive calls, and majority of the time I just see the dailer timer progressing but no audio output from the earpiece speaker. When I insert headphones or try speakerphone I am still unable to hear any audio from calls. However, music plays just fine from headphones. I can also send texts and MMS with no issues. Sometimes when power cycle the phone it will work for a couple calls only.
I have literally tried everything. Flashed different modems, went back to stock touchwiz, numerous factory resets, removed SIM/SD card, etc. with no luck. I am currently on the latest GPE build since my GS4 has the MDK bootloader. I have determined that it is not an issue with this ROM itself since no one else is experiencing this issue and I have seen it on the other ROMs I have recently tried.
If anyone has suggestions I'd really appreciate it. I have searched for days online and have not been able to find a solution that has worked, and I am beginning to think it is a hardware issue although my call audio works some of the time. Any input would be greatly appreciated.
OK Google Voice Search
I had a similar issue. I was able to resolve it by disabling the setting where you can say OK Google from anywhere on your phone and that fixed it. Unlike you, I am on the latest update, rooted. Maybe try messing with OK Google Detection settings, disable all of them and see if it starts working, then re-enable 1 at a time until you find the issue.

Redmi Note 9 Pro Speakerphone is always active on custom roms. can't switch to earpiece

Hi, I'm having a issue with my redmi note 9 pro. Whenever i try to make a call, it always goes to speakerphone. I cannot get it to go to the earpiece. WHen i try turning off speakerphone, the audio is still routed through the bottom speaker, and the person on the end of the call notices i sound broken up. WHen i swotch on the speakerphone the sound is clear, and then the person can hear me just fine. I've tried with whatsapp, google voice, and the regular phone app, and all have the same issue. I'm running Evolution X currently as my rom, but i've tried lineage os, and it has the same bug. On stock MIUI I don't remember having this issue, so maybe it's something weird with the custom roms. I'm also rooted with magisk. Anyone got any ideas, or has anyone ever experienced this issue when running custom roms on this phone? Any ideas, or suggestions are welcome. Thanks
Hi, I have this problem too. Of course inside the pubg mobile game. To temporarily solve this problem, first turn off the phone and connect the headphones when the operating system logo is displayed. A hissing sound is heard when plugging in the headphones.
Of course, to avoid this problem, you should use Bluetooth headphones.
Hi, I just tried your suggestion. it doesn't appear to work. My issue is with the earpiece, not headphones. Headphones for me have always worked flawlessly when running custom roms or stock. My issue is when making calls using the earpiece. Making calls using headphones seems to work fine. However when trying to use the earpiece, i cannot get it to work. What i mean by earpiece, is the top speaker of the phone, the one you have to hold close to your ear when making a call. FOr whatever reason calls always remain on the bottom speaker, and never seem to go to the top speaker aka earpiece. This happens in all calls, and in apps like whatsapp. Has anyone else ever experienced this issue? Again, headphones seem to work fine, and yes I'm rooted, and running a custom rom. When i was running stock, I don't ever remember this happening, but now that i'm running a custom rom, i can't get the earpiece to work. I really don't want to go back to the stock miui rom, but idk maybe i will if a solution can't be found

I am having the same issue! any solution please let me know!
I am having the same problem - BUT on stock MIUI 12.5 - it started happening after I upgraded. If I could go back I would, but am happy to flasha new ROM if that will fix it.
I was thinking of flashing Lineage 18.1 but if that is having the save issue I ont bother. It must be a note 9 pro issue seeing as I only have the stock version..
I wonder if anyone at all has fixed this issue. I even contact xiaomi technical support but they were useless!
Anybody found its solution please update?
I'm having the exact same issue. When I initiate call it's on loudspeaker even though I didn't select that option. The other side can't hear me well. When I select "speaker" then it's still on loudspeaker, as it should be, and the other person can hear me fine.
I had the problem on crDroid (Android 12) and am currently experiencing the same problem on Pixel Experience (Android 12).
Please help someone us
I found the solution when I changed sim 1 to sim 2 the problem was solved.

Not quite sure I follow. Are you saying to remove sim 1? Or are you saying to change the default calling sim to sim 2 or something? I should note that I'm using both sims and a SD card. Are you saying I should just use sim slot 2?

Short version:
OK, so I just tried your advice, and it WORKED.
Long Version:
Ok, so I first removed both sims with the phone off. Then i put one of my 2 sims ONLY in slot 2 like you said. I inserted it into the phone, booted it up, and made a test call. To my surprise, the phone wasn't on speaker. I couldn't beileve it. I tried again, and it worked. I switched to speaker, now it's on speaker. I turned off the speaker and it was back to the earpeice! I tried whatsapp, and same result, the earpiece was working. I then decided to shut the phone down, and put the both sim 1 and 2 back in the phone. Guess what? after booting the phone up again, and making a test call, it still works! I don't understand the rhyme or reason behind it, but I'm not complaining. I'm so happy it FINALLY works.
to recap, Basically here are the steps:
1. Turn Off phone
2. Remove both sim cards.
3. Put a sim only in slot 2
4. Turn on phone and make a test call, it should no longer be on speaker!
5. go ahead and shut down the phone, and put a sim in both slots, if you are using 2 sims.
6. Turn the phone back on, and make a test call. It should still be working on the earpiece!
yes - this worked for me also - I have been looking for so long. A simple and un-remarkab le solution to a serious problem. Xiaomi should have been able to solve this.
All the same - thank you!
Great phone that was hindered for quite a few months by this serious problem
Again - thank you !
