Background noise with headsets connected to the phone - Xiaomi Redmi Note 4 Guides, News, & Discussion

Hello everyone,
since few days, when I talk to the headset, the person who receives my call hears an annoying background noise, like when you approach a phone to another phone; if I disconnect the headset everything returns to normal.
I tried to change the headset but the result is the same: what can I do? Do you have any suggestions?
Thank you very much!
EDIT: Redmi Note 4 Snapdragon with MIUI Global 10.2 _ 10.3.2.0 Stable

[Q] Very specific problem with voice dialing from bluetooth headsets

Hi everyone,
First off, I'd like to start by wishing to everyone happy Holidays!
I have been literally searching all over the Internet for any information regarding the issue I am about to describe in detail and since no solutiuon was found, there's nothing left for me to do but ask for help, and hopefully get the right answer. That's why I want to be as specific and informative as I can.
The problem I am having is this; I recently purchased a new Jabra Motion bluetooth headset and decided to start using the voice dialing function on my Galaxy S4, since it works very well (when it works) and is really a breeze, especially while driving.
In short, the problem is that the S4 completely loses audio (other party hears nothing as well) after initiating a call, via voice dial commands through any bluetooth headset (I'll get to that). When that happens, the phone has no in-call audio whatsoever (with headset on or off, with speakerphone or earpiece on), no matter how many times I start or receive a call and nothing brings audio back, except a reboot from the i9505's power button menu. All other audio works, like videos, unlock sounds, ringtone, music, even the little chirp right before the other party's phone starts ringing and the hangup chirp can also be heard. The worst part is, that it occurs completely at random, it can happen on the 1st time I voice dial or the 10th time, for example. The problem has not shown itself, when initiating a call normally or picking up with a headset connected, before audio gets lost.
Before purchasing the Jabra Motion I've been using an earliest model Jawbone Icon and had never even tried the voice dialing feature on any previous phones or the S4. After encountering this problem I tried to test whether or not it would happen when using that headset, the result was yes, so it is safe to say it will happen when using any bluetooth headset, with the same randomness.
This is what both headsets launch on the phone, when attempting to voice dial:

The phone itself is a completely stock and un-rooted 16GB Galaxy S4 i9505, running the latest available Jelly Bean 4.3, build: XXUEMJ7.
The headsets are always connected to 2 devices simultaneously (in case that might shed some light)
What I've tried so far (no difference made, at all):
- Toggled bluetooth off and on
- Tried unpairing and re-pairing both headsets on both phones, or only on i9505
- Tried factory resetting both headsets
- Tried to toggle, while in call, between speakerphone, earpiece, headset, turning off headset and all possible combinations
- Removed Jabra companion app and services app, then reinstalled, then tried without the apps installed.
- Cleared cache from both Jabra apps.
- Cleared cache from system apps such as dialer, bluetooth and Google Search.
- Contacted support of both Samsung and Jabra (huge waste of time)
Sorry for the very long post, but I want to be clear and comprehensive as possible. Any help would be highly appreciated.
Please no factory reset suggestions, I am aware of that possibility, but do not want to go through all the trouble to set up tons of apps and stuff again.
Thanks in advance to anyone willing to help!
Anyone?
Please?

CM11 ringing with phones connected

How to make phone ringing on speaker when phones are connected like stock rom ?
It only rings in earphones and I need it to ring on speaker.
All the CM builds I tried are the same, not ringing

I'm afraid It cannot be done. But hey, this behaviour is more natural for me. I've also found a topic, where guy complains about not having your issue
Natural if your headphones are in your ears all the time.
But i use headphones just on work, cant hold phone all day, and when someon calls or sends sms to me, i dont hear nothing.
There is vibration, but that is not enough.
Stock rom is ringing with phones connecte !!!:crying:

Video Call Sound issues

This problem seems to be new.
Whenever I Video call, Skype or hangouts. My call volume is so low that i can barely hear the other person. Even with the volume turned all the way up in settings its still so low i can barely hear them. I thought maybe it was a hardware problem, however when i play music or even use speaker phone on a non video call the sound is loud and clear. Something seems to be switching the volume to a much lower setting right as the call picks up. Has anyone else seen this problem?

Hello... I'm posting almost a year after yours to say that I had the same problem with my Note 3 on JasmineROM 2.4.4. I never looked into it, because I didn't do video calls very often, and I just got used to using a bluetooth headset to make the calls.
I now have a Note 4 Developer Edition, and I gave the Note 3 to my wife. We did a video call this morning, and she said she couldn't hear me at all. So, the problem has come back. But, the problem is... she can't just use a bluetooth headset because we do video calls so that I can see my son when I'm not at home... and I want him to hear me. Good luck keeping a bluetooth headset on a toddler.
Did you ever find a root cause (or a solution) to this problem?
Thanks.

Hi.
It might not help, but I've got a very similar problem.
My car has integrated Bluetooth.
As soon as I get in the car, then get out again (with the Bluetooth being connected), then I "lose" the microphone.
If I make/receive a call, the person on the other end can't hear me. Voice recording app shows no microphone activity.
If I turn Bluetooth off, the microphone starts working again.
As far as I know, this has only started happening since the most recent Wileyfox update.
Hope this helps.
Pete.

Problem with the microphone after upgrading from JOYUI 10 to JOYUI 11.

As in the subject, after updating on JOYUI 11 while making or receiving calls after about a minute and sometimes five minutes (no exact time) the microphone stops working and my interlocutor cannot hear me. When the microphone was not working anymore, switching the call to the speaker also does nothing - my interlocutor cannot hear me anymore. The microphone icon indicates that the microphone is on. Pressing this icon indicates that the microphone is muted, and pressing it again indicates that the microphone is on, but the microphone still does not work. Then I have to disconnect my caller and make the call again. Sometimes the microphone works all the time during the call and does not turn off. I don't know what it depends on and what turns it off. I suspect that the proximity sensor may be responsible for turning off the microphone, because I noticed that when the phone is pressed to the ear with the entire surface, the problem with the microphone occurs very rarely, and when I touch the ear with the top edge, the problem occurs often. When I am talking on a cordless handset or a cable headset, the problem does not occur.
There is also no problem when I make or answer calls and switch the call to the speaker immediately.
In all other applications and device tests, the microphone works without problems.
I am asking for help in solving the problem because it is very annoying.
The device is: Xiaomi Black Shark 2 8 / 128GB

JOYUI 11 20.04.22

I have sent an email to the developer and he replied that he will fix it in the next update.
