Question Static / crackling on voice calls for receiver - Redmi Note 10 Pro

Hello i recently got my redmi note 10 pro i removed most of the bloatware everything has been running well and good battery life etc no real issues had few problems with notifications not showing but fixed it mostly
However when using telegram calling the person i was speaking to kept hearing really loud static sounds every 30-40 secs i tried with both volte / 4g / wifi and had the same issue
I have requested a refund for the phone as i do not want to spend this much money for a product with issues within the first 3-4 days has anyone else experienced this ?

The problem is likely a loose wire somewhere in your headset or cord. ... If you do, looping the wire and taping it down at the point of the loose connection may temporarily stop the noise until you can have the connection re-soldered or replace the headset.

Phone interfearing with speakers?

This is a rather odd problem im having with my tilt, and was wondering if its just me. Whenever my phone gets a signal, if its within 3 feet of ANY speaker, off or on, the speaker goes crazy! Its the same pattern of tones, sort of like a fax machine handshake. I wear my headphones alot, and can tell when I am getting a call even before my screen turns on, and its rather loud. So, now when I wear my headphones, I need to place it about 3 feet away from me, and the headphone cable. Also, the phone dials up about every 10-15 mins, even when sleeping. I can hear this also. Its also not limited to headphones, but any speaker. I had the phone resting on my alarm clock, and the speaker went crazy when my wife called!!!
This sort of magnetic interference is insane, and frankly not tolerable. I have an ATT Tilt and tried a few different radio's in diff ROM's.
Very common. If you take the cell phone near to a CRT computer monitor (not LCD) right before a call / text, the screen will also show you lines.
My all phones did the same. I bought this AT&T Tilt phone running stock WM6.1 and until I flashed a cooked ROM on it, it did NOT give me these sounds through my speakers and I was amused!
The day I flashed it with a cooked ROM (and obviously a new radio / different radio) the sounds came back. This is purely electrical interference. The only solution is to keep your cell phone away from your speakers if you do not want to add additional shielding to your speakers or buy a different / better phone.
More information? Google it and you will find a lot of information on this issue.
Thanks for the info. I have had a few handsets b4, but nothing as big and complex as the tilt (Razor and cheap clamshell) and none of them gave me the problem im dealing with now. Its rather crazy to think that such a small device is putting out so much magnetic interference!
RF exposure anyone? i've noticed that my tilt causes a lot of interference even when at a distance. I'm getting rid of it as soon as I can.
This used to happen to me, then AT&T upgraded the network in my area to 3G. The band that 3G operates on is different than that of the Edge or 2G networks. I could never have my phone within 6 feet of my computer at work due to the loud noise. Now, It charges right next to the speakers all day with no problems. Hope that helps.

[Q] Speakerphone and mic problem

Dear friends,
First of all sorry for my bad english- I didn't have a practic for a long time.
Probably you can help me in my trouble with N1. I got a next problem:
Some time ago the microphone and speaker phone of my N1 became disconnected unexpectedly. After
disconnecting they not working constantly in the phone mode and in other applications both. The
headphones also not working. But! If then I'm push the "speakerphone" button during the call - I get
the possibility of talking (but only in speakerphone mode). If I want to call not only in speakerphone
mode- I must to switch off the phone at least for 10 minutes. After 10 min I can switch on the phone
and then it working perfectly till the next trouble.
I found the reason- it always happens after the bottom of my N1 is hot (battery sensor show me in this
moment 34 degrees or more. And this never happened when the temperature less than 34 degrees).
Our phones repairing workshops can't localize the problem, so i want to find the problem by myself and
request the specific kind of repair like "make solder legs of audio controller, etc". I don't see any
way.
The questions:
1. Can anybody share with me schematic diagram of N1?
2. How to check the log of N1 errors (is it radio unit or no?) via the ADB (already installed); I need a step-by-step instruction.
3. Any other ideas
Thanks in advance!
Hi DPH159,
at 1st i`m sorry for your probs...hope we`ll find anybody for this solution.
i`ve had quiet near the same probs with my N1
my probs are on calling someone or picking up the phone after incoming phone calls.
outgoing calls:
theres nothing...no beep no answer...no noise on the normal way when i call someone
as far as i`ve test it...the dial-up is running well
but when i put somebody on speakerphone...i can talk pretty good but only on speakerphone-mode...but thats not the perfect solution
i can`t talk everytime via speakerphone ;(
is there anybody who can help?
many thanks!

Can't hear nor can other person hear during call?

So I'm on my 11th day of using the Nexus 6. I have 14 days to exchange the phone through T-Mobile if there's any issues. So far, no real hardware issues with the phone.
Here's my issue though. It's so random I can't figure it out. When I'm trying to call someone, the dialer dials the number, reaches the contact, but I can't hear the ringer and I can't hear anyone talking on the other line. The person on the other side of the line said when they answered the phone, there was no sound or voice from me - it was just dead.
The ONLY way I seemed to fix it before it does it again is to reboot the phone and calls will be normal. My question is, should I exchange the phone? It shouldn't be hardware, right? It sounds to me like a Lollipop issue but I don't see anyone else with this issue. Please help as I want to make up my mind whether or not I should swap for a new Nexus 6.
I'm running stock unrooted and locked bootloader. Thanks.
EDIT: I'm on T-Mobile too.
in for update please
same thing would happen to my wife's nexus 6 too. happens sporadically. don't know what causes it. doesn't happen often. hasn't happened with my nexus 6 yet. i have the blue 64gb and she has the cloud white 64gb.
notice the same thing happening with my father's nexus 4 a couple times too. only way to fix both phones is with a reboot.
thinking that it is a software issue and hopefully will be fixed with the next release of Android 5.1 since that is supposed to mainly be bug fixes.

Are you on T-Mobile? I ask because I think my issue was more an issue on T-Mobile's side. My friend has an iPhone 6 and he had the same issue - it was T-Mobile's cell tower. I'm not 100% sure this was the reason because I still had to swap out my Nexus 6 when I originally posted this because of hardware issues.
Same problem here, answer an incoming call I can't hear them, they can't hear me. Rebooting the phone fixes the problem but only for a few days , then same again.
I'm on AT&T and had this problem yesterday, got a VM from my daughter's school saying there was a 2 hour delay and couldn't hear it (ended up seeing it in my e-mail instead). Then I tried multiple times to make/receive calls same thing. Rebooting the phone fixed it. I wasn't sure if it was a bug since I rooted or not. I've only had my phone for 6 days.
This has been driving up the bloody wall. I hope they fix it soon! Anyone got any ideas?
Guys, if you have to reboot the phone to fix the issue, I would RMA or exchange the phone. It could be hardware since it's happening on different carriers in different areas of the world. I'm on my third Nexus 6 and everything seems to function fine now.
I actually fixed mine by blocking the noise cancellation speakers at the back of the phone below the camera. If the nexus 6p is in a case all you need to do is cover the noise cancellation hole in the case and you will be fine and if not in a case just cover it with a tiny sticker
Having similar issue on Nexus 5!
Problem: When I call or receive calls - I cannot hear anything --- unless I switch to loudspeaker or use a headset.
Furthermore when dialing I cannot hear the connection sounds --- unless I switch to loudspeaker or us a headset.
The others can hear me! So - the microphone works.
I can record and play audio & video - no problem! So the microphone and the speaker do work, somehow not always! Vibration works too.
----------FIXED
P.S: I just got it fixed: It turned out the earpiece speaker contacts were bend and the sticky tape did not hold the part down. After bending the contacts and taping the earpiece down (alternative a small piece of paper to force / hold it down did the job!)
The earpiece contacts only presses upward against the board contacts of the Nexus5 (and 6 likely)!
Currently: Nexus 5 / Nougat 7.1.1 / Nitrogen OS / rooted on TWRP 3.0.3.0 recovery

Inline-microphone stops working during a call

Does anyone has issues using a headset to take calls? I bought a OnePlus 3T last week and while I like the phone, not being able to reliably use headset for calling is a no-go. Here is what's happening...
I have a Panasonic ErgoFit Headphone with Mic/Controller which used to work flawlessly with my Nexus 5 and my wife's HTC One. On my brand new Oneplus 3T, the inline microphone cuts out in the middle of the call.
There are a couple of ways to this happens:
At any random moment during a long running call (more than 2-3 mins), the inline mic will stop working and the person on the other side can't hear anything
If during a call, I switch from the call-screen to another app and come back to the call screen, the mic stops working.
I can usually get the inline-mic working again by trying either one of these, but if that fails I have to stop using the headset:
Toggle the phone speaker on/off
Unplug and re-plug the headset
I like the phone, but reliable calling is must, I attend several long-running conference calls every week and it's quite frustrating when people think you've dropped off. I spoke to support and they told me I should use the official OnePlus headset and that's just not right.
Has anyone faced this issue or know of a fix? I have also documented this on OnePlus forums at https://forums.oneplus.net/threads/inline-microphone-not-working.475852/#post-15460410
Thanks.
Hi,
I have the same issue. did you manage to fix it?

Any way to shut off Noise-Reduction while call with speaker

Hello folks,
i purchased a Note 9 and I am getting in trouble because I cannot use the phone as i used to do before. When I have a call with someone and I use the speaker for free-speaking (or the usage of a car-mount in combination of the headphone jack connected to car while driving) the in-built noise-reductions destroys nearly every call. People cannot hear me correctly, because the noise-reduction is so hard, that it cut offs a lot of the words I speak. The result is, that people cannot understand me.
I contacted Samsung for this and they verified that this is a common thing for samsung phones, because their intelligent noise-reduction should turn out every other sound - sadly it also removes the own sound. I can only speak with speaker mode, when the phone is on my desk or in hand and there is no noise. Even when I have the phone in the sink while washing my hands (common corona-stuff) people cant here me correctly anymore due the filter of the water-noise.
Samsung has no option to turn off this "feature" and the mic works perfectly for recording audiologs or whatsapp-voice notes.
So my request now is: Is there any way to get rid of this noise-reduction-feature while in Call?
I could imagine that maybe root gives access to this function or maybe also a custom rom. Can anybody help me with this and giving me a good answer ?
