Call Sound Quality

Hello,
the sound quality is very bad. The strange thing is, the problem occurs only using the phone app. I am using the stock phone app.
Any idea? I need help. All other things are working but I can't use the phone to make calls. It sounds like distortion ... . Already the sound during ringing has the problem.
The problem only occurs with the internal front speaker. No problem if I use the rear loudspeaker or headphones.
Is there a wait to solve the problem?

Call Sample
Hello,
here is an call sample. I know the quality is not perfekt beacause of the notebook fan. I call another phone and after ringing the mailbox of the called person starts. Especially at the end were the mailbox voice occurs the problem is very clear. It is nearly impossible to understand what is said.
Is this the normal sound of the internal speaker (front)?

of course not.

Hello,
thanks for the answer. Found the following thread.

Strange thing I am also using this phone in Europe. I am quite sure the problem is not a hardware problem. Because if I use the phone with VoIP service app, the speaker just works ok.

I would try a clean flash of a custom rom, factory reset maybe (was it always bad?..)? I also had problems with the internal speaker, if I have set the volume higher than half, it made crackle sounds. But it was a hardware issue, (in skype, fring,viber also had this problem). I had to send it back to the usa, cause I live in europe and literally no one could fix it here because of the lack of hardware. I had to live without my phone for a month.. annoying thing, but now it's ok

First of the time after buying I didn't use the phone for calling. With Skype I will try again. Also the VOIP test. How did you manage the repair? With ATT or Samsung?
Its not only because of the time. Also because of the money for transport and repair.
Thanks for answering and help!

Microphone doesn't work during calls with stock app

If I make or recieve a call with the stock sony call app, the other party can not hear me unless I switch to speaker. I tried with different people, it's always the same.
However, if I use google hangouts for calls the both the microphone and the spaker work just fine.
If I record a voice message in Whatsapp, the microphone works but is really low.
If I use Trackid for a song the microphone doesn't work again.
This has only started a few weeks ago and I can't find any solution on my own. Anyone has an idea what the problem could be?
I already tried safe boot and factory reset, it stays the same. I am really confused as it only happens in a few apps while working fine in others.
Thanks in advance!

That didn't work :/
But thank you for your answer

I submitted my zl in service centre for 25 days and they do nothing , always keep saying that parts are coming. Finally I ask them to give it to me without replacing the microphone as i have to go somewhere, Finally I factory reset my phone use a pin,cotton and and some water in the microphone then blown some air And it WORKED. So most probably its the dirt. For your hangouts working it might be your phantasm.

ZL C6503 microphone problem

I just received my new ZL C6503, and am on stock 5.1.1. It seems like a great phone, but just noticed that people can barely hear me during a call. I can hear them fine though.
I tried playing with the mic/call settings, like noise suppression off/on, etc, but to no effect. Anyone had same issue? How could this be fixed?

Go to service menu by typing *#*#7378423#*#*
Then go to service tests and go to primary microphone. test it there. That will help you point out if the problem is with mic or not.

Thanks for the advice. I tried it. It seems the mic does work, although its extremely quiet. What can it be? I have unlocked bootloader in case that matters for anything. Or should I try a different rom? I have the latest "nordic combined" flashed at the moment but I got the phone from HK as refurbished.

It could be a matter of the room, it happend to me with a S5, I know its not the model, but after doing a clean reinstall of the room the mic was working fine, so try to reinstall or change rom and see what it happends

Highly chances is hardware issue. I have ZL which also have problem with primary mic. During calls I use loudspeaker,fortunately it works, mayb using the secondary mic behind.

Check this video to see the dissasembly and check your mic. https://www.youtube.com/watch?v=7yADs4OsAXg

When making a call, can't hear calling unless on speaker, also, i dont have SMMI Test

Like i said in the title, i cant hear the dial tone when making a call(unless on the speaker), if the person im calling answer the call, i cant hear him, if its me answering the call, the other person cant hear me neither. I tried to use the SMMI Test to see if it was a hardware problem, but when i use the code on the calculator nothing happens, also i tried safe mode to see if it was a software problem but the problem remains. It's the Asus Zenfone 2 ZE551ML if it matters.

Well you can turn on the dial pad tone in the phone settings. but the problem with you not hearing them and them not hearing you, that's something else. I've had to send my phone back twice for an issue like that. they say they replace the Motherboard, but the issues is still there. on and off. maybe this thread can stay around to get some different views on the issue.

Me too facing the same problem..any solution to this?
Sent from my ASUS_Z00AD using XDA-Developers mobile app

Disable ok Google from any screen option or uninstall Google update which is causing this problem then test.
After uninstall Google wipe cache partition then reboot.

Third Party App "SoundAbout" may be helpful

I had similar problem with my HTC one X , after I flashed some patch for sound enhancements. I searched on google then found a solution on reddit which suggested to use a third party app named "SoundAbout". It routes the speaker sound to earpiece. has many settings and thus may be useful. I could still use my old HTC one X with this and satisfied. This is not a permanent solution to the root cause but at least it is useful to some extent.

Volume reduces significantly if video calls interrupted by cell phone calls

Hi Guys,
I have a peculiar problem. I run Android version 10 on One Plus 7T Version 10.3.2.HD65AA, Model HD1901
I do a lot of video calls on my job . When I am on a video call on a loud speaker and it is interrupted by cell phone call, even if i accept or reject the cell phone call, my loudspeaker volume significantly reduces to be inaudible levels .The volume is maximum , but its inaudible. I have to disconnect the video call and restart the phone to be able to converse on loud speaker. This is very irritating and affecting my job. I have tried to search a lot and have not found any effective answer . This happens even with headphones .
I notice this typically on whatsapp video call and browser based video calls like doxy.me. With zoom and google meet, i am logged out if i accept the cell phone call, so i have to rejoin the meetings and the sound level is audible.
I would really appreciate any piece of advice on solving this issue as its interfering with my job, besides being a nuisance.
PS : I have had to factory reset my phone twice recently for other reasons as below and it still has not solved this issue .
1. I had missing icons in my top shelf in contact app ( plus sign , delete button , hamburger bottom) and file app (hamburger sign , find button and delete bin) after one particular update
2. Had notification problems which again needed factory reset
Thank you all in advance

I did update to open beta 3. Unfortunately that has not helped.. The volume still went down when the phone call came.
This is frustrating honestly.
Thank you for your help though.

BUG: Phone speakers won't work after video calling
Device: Oneplus 7T on 10.0.9HD65AA
How to reproduce:
1. Video call using facebook messenger or similar app
2. Play music or video thru speakers, they won't work
3. Restart phone, speaker will work again
*note: there is a faint sound coming from the earpiece, like when you're calling someone
Already reported this to OnePlus. Very frustrating bug.

My problem could be this bug that u reported. Did they reply back to you?

I just had this happen when using MS Teams on a conference call. I had speakerphone enabled, and a call came in. I declined the call, but the Teams call switched to the earpiece (which was of lower volume). To fix, I just switched from Speaker, to Device and then back to Speaker. This happens on AOSP (on my OnePlus 5T) as well.
I don't think it's an Oxygen problem, but it's something that can likely be fixed if they know about it.

After installing AOSP on the 7T, this continues to happen with Microsoft Teams meetings when I have speaker enabled, receive a phone call and decline it, and it switches automatically to earpiece.
The solution of switching to earpiece in Teams and then back to speaker fixes it. All without disconnecting from the meeting.

So this did work for me. Today when the volume reduced after a phone call during my zoom meeting, I plugged in my ear phones and then removed them after 2 min, the volume was back to full and audible.
Thanks a lot for this tip. It's a life saver for me. Really appreciate it.

You're welcome. It's more of a workaround because it seems audio routing is just wonky in Android. I'm not sure if iOS does this but I can test that later with wife's phone.

Yep! Same here, MS Teams meeting, BT headset, dropped incoming call to voicemail and meeting volume became inaudible, so I had to drop and reconnect. Very inconvenient, especially because I was the meeting's host. I will try to switch audio device in Teams next time, kudos for that!
