Problems with this smartphone - Xiaomi Redmi Note 4 Questions & Answers

Hi, are there any problems with this smartphone? I'm coming from a Moto G4 with a screen burn-in issue, and I've read somewhere that this phone has it too, but I hope only some phones have it.
Also how is the microphone issue that some people claim it to have a bad quality? Has it been solved with official updates or only with community solutions?
Any other issues that I should be aware of?

I'm using xiaomi.eu rom right now, first time unboxing i got global stable MIUI8 rom, updated it to MIUI9. These 3 rom i haven't encounter any bugs related to audio, incall is fine, speakerphone doing good, recording audio or video went nice.
But i also try aosp custom rom, AEX, RR, even Xenon HD gave me the incall bug, nobody hear me whether i do the call or i took some calls.
the only way i can chat is using the apeakerphone mode.
i'm reading and searching for the same problem but no one did.
they had aosp custom rom running fine
do i did something wrong while flashing the rom?
only God knows

Speakers Crackle aosp and other non sense roms

so I flashed a cm11 rom then a aosp rom then other roms kept getting the same problems crackle speakers and not being able to use my phone in speaker mode when making calls nobody can hear me so does anybody have a clue what I should do to fix it or flash to fix it pretty much a newbie here so excuse me for my ignorance :/
All aosp roms are really buggy on the m8. Speakerphone is finally fixed but still a lot of other issues are still there. Maybe try sinless gpe for the time being.
I tried that rom you mention its works great!!

Other side hear echo on phone call

Hello guys.
I have been facing a problem for a while. Some people whom i'm talking to are complaining that they can hear their own voice while we are speaking on the phone, like some kind of echo; I tried a few solutions like moving the sim to another slot. I even gave up on MIUI by installing a custom rom, with no success as it seems.
The problem disappears while i'm using the earbuds or i'm talking on the speaker. So please if you know any solution to my problem, please replay cause it's annoying as hell.
Thank you sincerely.
i also have this issue
I think it's an issue with the noise cancellation or something like that...
Exactly the same issue, exactly as the OP described. Any solution would be much much appreciated.
Note: I am using the beta MIUI build with Android 9, I'd be willing to roll back to a stable build if it solves the problem.
i´m having this problem too. MIUI EU ROM. haven't tried with other ROMs. i think i didn't had complains with Stable... not sure.
please help has this is very annoying.
Actually, I face this problem when I'm using headphones but if rotate the pin in the jack it fixes itself. Otherwise no echo.
I have this problem too! There are any think that we can do to minimize?
I'm with MIUI 10 Global 8.12.27 Beta
I had the same issue, I've posted a fix that works for me, you can try it if you have root: https://forum.xda-developers.com/poco-f1/themes/fix-noises-echoes-mic-t3886049
As suspected the problem is with the Global Beta... I switched back to Global Stable and the problem is gone.
Hi,
Could you please confirm this issue at the following thread? https://c.mi.com/thread-1894332-1-0.html
Regards,
Issue fixed (at last!!) on latest MIUI stable 10.3.5 for POCO F1

[BUG] Weird sound during calls on bluetooth

So i'm currently using kenzo as my main device. I had RR Pie installed until I came across this very annoying bug. I use a bluetooth headset for almost 4-5 hours everyday. It all worked fine until I noticed that calling using the headset was impossible. There is a sound like a machine gun is being fired in the background. It makes my phone obsolete.
I thought this was a bug on RR so I changed to Pixel Exp. and the same thing is happening. Couldn't find a solution on the internet but found a person who posted on the RN3 forum here :
https://forum.xda-developers.com/redmi-note-3/help/call-bluetooth-audio-problem-oreo-pie-t3836462
According to this guy, the bug is present in the oreo and pie roms. I haven't confirmed this myself. I am still downloading the stock rom to test it out. I guess it has something to do with the bluetooth modem. I will keep you guys posted on this. I hope someone replies to this.
UPDATE : I installed the stock rom. It's working. It's a bug on Pie and Oreo roms.

I flashed the Stock Rom just to test things out and it's working again. AOSP Extended doesn't have this bug ? I would be great if it doesn't.
Update : Flashed AEX, working fine.

Poco f1 (low earpiece volume)

Hi,
I have been experiencing low call volumes since few month's, exactly don't remember when this started and what was the reason behind it.
I tried out all the possible troubleshooting methods but nothing worked till now, but there is one strange thing that when i use whatsapp or any other internet voice call applications the sound is normal, loud and crystal clear. The only issue is with the normal calls.
I'm assuming it's because of the last update of miui 11.0.8, though i am not sure but i have strong feeling that the update is the issue.
I'm running MIUI 11.0.8 Global Rom and phone is not rooted neither bootloader is unlocked.
If anybody know what's the reason behind it or anybody has a solution for it, kindly share asap.
And if someone else is experiencing the same issue do share your feedback on this thread.
Any kind of help and feedfack is appreciated.
Thanks
i'm facing the same issue best case to wait for another update to fix it
Maybe you should try to clean the mesh that is on the speaker.
Mine mic totally "glued" by dirt ( I bouth used phone). It was hard to clean it without damaging the mic. Try isopropyl alcohol.
I guess its 11.0.8 update issue. Lets wait for next update till next year. ****ty China.
Do you guys think factory reset will solve this issue?
Did 11.0.9 update resolved this issue for anyone?
Guys one thing i can confirm is, its not due to the software. Thinking its the Miui,i rooted the phone and flashed Corvus ROM, but still the issue persists..

Have you tried flashing custom kernel?
Maybe that might help.
MIUI comes with Silvercore kernel and most probably Corvus comes with the same.
I suggest use optinus drunken or sphinx kernel
I hope its helps you.
I did flashed sphinx kernel.. even though it's better than previous but still is low..
Is your device rooted?
No.. by rooted means ' did I flash magisk?'.. no I didn't flash magisk..

If you've tried all possible methods on the software end then it might be an issue with hardware. If you have a local cellphone repair, might want to have it checked.
Actually after a day flashing the kernel, the audio volume has increased significantly.. guess the new kernel is learning the volume.. finally now I am able to use my poco F1..

Just an update.. the phone is back!!! Kernel was the issue. After flashing custom kernel microphone volume is fixed..
Which kernel did you flash?

I use to sing in Karaoke apps. What I noticed that this is the issue with Firmware itself. All Android 10 firmwares like 11.0.4, 11.0.6, 11.0.8 and 11.0.9.
Because when I flash any Rom based on Android 9 with any Pie firmwares till 11.0.5 I use to set my Mic gain to" -2" in Karaoke apps... As it's too loud.
But when I use any Android 10 rom with Android 10 firmware then I have to set Mic gain to "+3.5".. as it's too low and I can't hear anything.. and even after setting it up at +3.5 it's barely audible..
This is not hardware issue at all this is particularly firmware issue. Because it's working fine in Pie firmwares.
If you don't believe then you may experience it by your own. Just flash any Rom based on 11.0.5 firmware and see the difference in Mic volume in any recording apps or whatsapp voice messages or video calls or Messenger calls etc
I have got the same issue. Don't understand why the volume is low. Did you find any fix for the same?
you can use Franco Kernel Manager, in the kernel settings it is possible to change the sound. but it needs root, i always use it with all kernel and roms you can buy it on playstore very cheap.

I try everything , new speaker ,many kernels with speaker gain nothing help and still low earpice volume.

Ear/top speaker not working for calls on any custom ROM

Hello all,
I own a Xiaomi Redmi Note 9 Pro Global (joyeuse).
I have been, for the last three days, hopping between all of the ROMs available for my device (joyeuse) only to be disappointed by one very persistent and insufferable bug on each.
Quite simply, none of the ROMs I have tried, as listed below, have a working speaker at the top of the screen. Some of them don't have any sound whatsoever, others use the large speaker at the bottom, and this is not adequate for me due to a fundamental desire for privacy and noise isolation in public.
I have tried, to name a few, crDroid, EvolutionX, ArrowOS, AOSPK, Pixel Experience, Pixel Experience Plus, and Pixel Extended. These are just what I can remember, I have tried more than this.
I have also attempted using the myriad of custom kernels available in effort to mitigate this issue. None have worked.
I even tried to flash over the ROMs with official firmware, and I thought about flashing vendor images from Xiaomi Firmware Updater but hit a dead-end, because I do not know how to properly flash the image.
Any assistance with this, or suggestions for a good ROM or kernel to solve these issues would be HUGELY appreciated, because at this point I'm considering buying a new phone for better ROM support.
I've seen reports of this bug since the device launched. It was listed in one of the weekly bug report threads in the 'mi community' app/forum. It had a status update saying the bug was in the chipset and xiaomi was awaiting a patch from qualcomm. The thread has since been edited and the update removed. That's all the info I have

yes I have the same issue after I upgraded to MIUI 12.5 - it's awful. I am still on sotck and was hoping to flash to fix the issue but it looks like other ROMs dont fix it. So I will sty on stock until there's a fix.
what. a. pain !!!!!!
Same issue for me. Currently running evolution x on my Redmi note 9 pro. This is a great phone, but this bug is driving me crazy. I haven't tried any custom kernels, but from what the original person said, it didn't help. Interesting. Does anyone know if this issue affects the Redmi note 10 pro? I'm debating on getting that but want to know if the Redmi note 10 pro has the same issue. Ideally, I'm looking for a phone with good rom support, and has dual sim, or esim and a micro SD card slot.
Any update on this? I'm on a joyeuse as well with the same problem.
I found a solution, please read here and let me know if it works for you.

It worked! Thanks! The only strange thing is the first test call after I booted up the phone, the earpiece was finally working properly but the loud speaker wasn't working properly when I put the call on speaker. But on the next test call everything worked fine again.
Glad it worked for you. I Have no idea why this works, or what the bug really is, but i'm pretty happy to have my phone working again.
