Sound bug (maybe) on Redmi 9C - Redmi 9C Questions & Answers

Hello, I wonder if anyone here ever experience the same issue as I have right now. My device Xiaomi Redmi 9C (4/64, MIUI Global 12.5.2.0) has, I think sort of bug where the sound suddenly muted/disabled.
I noticed this for the first time when I watched Youtube. The problem affect another apps as well, such as music/video player, notification, etc. In short, anything that has to do with sound.
When I did restart on the phone, the problem seems to be solved but the sound will ocassionally disabled again. If you have any tips to fix this problem, please share it with me.
Thank you in advance.
Note: please excuse my english since it's not my primary/daily language.

I was using MIUI 12.5 and also happened to me that problem and apparently it is the fault of the ROM,it seems normal to me since it is the first version of MIUI 12.5 for 9C, then I can come to understand because it is a problem that with a reboot is solved,hopefully the next update of MIUI 12.5 solve it

I see. Yeah, hopefully they will fix the bug on next update. In my case, after trying some random methods, the bug always triggered when I enabled autoplay on Youtube. I haven't experience the issue again since I disabled that feature. That way, I don't have to reboot my phone again and again. Kinda weird fix though.

Random freeze on xiaomi.eu Miui 12 rom

Hi I have been using the miui 12 with eu rom since the first beta but the latest updates destroyed my phone. My phone completely freeze like 30% of the time when I unlock the lockscreen, 90% of the time when I close the facebook messenger buble by swiping it down. Right now I'm on stable and I'm using candy kernel. This hasn't been resolved since the lastest 3 updates or so. Anyone else having the same issues or any solutions?
Same here on Mi 9T Pro , miui 12 latest stable, everything is stock here

I'm using 20.6.18 stock kernel, no issues here. Popup windows are a bit bugged but other than that it's fine. My browser occasionally freezes, forcing me to go to my homescreen and back into it but that seems like an issue with said browser. Sounds like an issue with Candy kernel to me.

Im having the same issue. Driving me crazy. Going back to the Stock China Rom for k20 pro. Dont know what else to do.
Same problem with Poco F2 Pro
Same here, with MI mix 2s, very frustrating ?
hello. i have the same problem i have figured out that if i disable the fb messenger chat heads, the problem is solved and i no longer have random freezes. can anyone else try it out and confirm if it works on you guys too?
I am experiencing the same problem on my Redmi Note 8 PRO.
The screen lags and sometimes freezes when I unlock, and freezes for about 3-5 minutes when closing FB Messenger bubbles. Then it kind or reboots and says something like, "The device closed unexpectedly" and goes back to the home screen.
From what i've read, a lot of people have also been experiencing this. I hope they address and hopefully resolve it soon.

yes. i have troubleshooted it and the problem is with chat heads. after disabling the fb chat heads i never get random freezes/reboots. once i re-enable it, they start again... i am so looking forward to android11 that have its own bubble notification system..
same . using 12.0.3 eu rom
It's been almost 2 days without freezes since I uninstalled messenger. I guess we have to wait until miui 13 to get it fixed...

Brightness problem after MIUI12 update ( 12.0.1.0 Global Stable)

So after updating my MI9, after finishing every call my screen goes very dark (like brightness was lowered to around 5%). Auto brightness is OFF as well as new Sunlight mode. How to solve that problem? Note that the brightness bar is still at 80% where I left it but screen goes very dark just after finishing my call.
I ve got the same and it was the same on Miui11

It was OK on MIUI 11 on my phone. I wonder how this isnt a hot topic on forums since its a very big and annoying bug.

Sorry. Same error happened in eu rom too. One of my friend's Mi9 with Eu stable rom. Same issue so....
I have the same on V12.0.1.0.QFAEUXM.
But i have also another problem. Firmware was installed clean. I did factory reset after updating.
The problem i am facing is lag in ui or even when browsing web (opera, chrome, edge). Its the same on all browsers. Scrolling is not smooth at all.
I can record screen to show problem. I cant use phone as its really annoying to scroll up/drown with all that lag.
Anyone have the same problem?
Thinking of selling phone at this point.
Wait for the fix. Xiasomi has best buy smartphones but the worst software, ever.

Yes hardware is good (camera could be better). But software is horrible. Poor optimization.
@Rajeev
Strange. Mine is lagging and is not smooth at all. That is biggest problem of this phone.
I never had this problem in MIUI 11.
Are you using QFAEUXM version?

Mine is V12.0.1.0.QFAMIXM and never had any lags or slowdowns. Phone is super fast. Though I turned off animations in devs options.
The only bug (and very annoying) appeared afte MIUI 12 update. The one I describbed in my first post.
Maybe that's the reason... I will try to set animations to .5x or turning off.
Edit:
Do you use stock launcher?

Question [Solved] Stereo speaker problem

Hello. I am facing weird bug with stereo speaker, upper one. Looks like it switches to earspeaker in stead of using normal dedicated speaker. When playing music , watching YT or any other media except when I make call and turn on speaker then sometimes it works sometimes it doesn't. I was on Chinese latest rom and was facing this weird issue but now I am on Global 12.0.3.0 and facing the same issue again. Since yesterday. I don't believe its hardware but anything is possible. I didn't drop the device.
Any suggestions or someone facing same or similar issue?

Had the same issue on Chinese 12.0.22.0 (hope I got it right
I am suspecting right now that YouTube Vanced is maybe causing this , because I had a lot of difficulties to make it work on Chinese rom and also latest version 16.02.35 don't work properly, always log's me out and having difficulties loging back in. So I am using 15.43.32 version which is working all right. Official YTVanced downloaded with YTV manager.
Also I am using SoundCloud app
And Musicolet player , but mostly YT ., So if non other than me is facing this issue I am guessing that could be some app causing this ... ?

Xiaomi.eu rom based on china rom, so i think as you, it is an app.
Sorry, i use YTV (non root) too, without issues.
MicroG 0.2.16.204.713, Vanced 16.02.35, no yt music.
Turning MIUI optimisation ON while using YouTube Vanced Official app will result in bug that turns off ond on from time to time stereo upper speaker
MIUI optimisation (last settings on the bottom of the developer settings) is ON by the default. When you install YouTube Vanced he is guiding you on how to switch it off in order to work properly. I ignored this for the sake of my phone working better as stated by XIAOMI when you want to turn it off. I was aware that it is some app causing this problem because it was impossible that I am the only one with it. So there you go if anyone encounter this problem just turn off MIUI optimisation

Question Redmi Note 10 Pro lagging after MIUI 12.5.2.0 update

Hi! I have a big and annoying problem. I have a Redmi Note 10 Pro phone that I upgraded from MIUI 12.5.1.0 to 12.5.2.0 2 days ago and have been struggling with lags ever since. I've tried everything, including a factory reset, to reinstall the phone from the recovery menu, but the problem didn't go away. It’s a pretty annoying problem that I can’t normally use my new phone I bought recently. Is it possible to downgrade MIUI from 12.5.2.0 back to 12.5.1.0? Or what should I do? Please help!

The same experience here, the device's performance has dropped significantly since updating to 12.5.2.0 and has terrible lag opening apps.
I'm still on 12.5.1, but have noticed that this broke the Google clock alarms - had that been fixed with 12.5.2?

The whole MIUI system is a mess. That's all I can say... I don't understand why there are so many bugs in the system with a phone like this. Xiaomi Developers should pay more attention to this.
i've no issue but app bugs cannot solved
i decided to go with xiaomi.eu still waiting to unlock the bootloader , looks like there are many differences
I am on 12.5.2 and I have no issues.
Turns off and on and works perfectly.
UPI apps is not working in dual app mode. Does anybody else also facing it? Any solutions?

Redmi 9 Problem: Occasional Reboots by Maxing out the Volume and etc

Hello, I'd like to asked if you guys also experience this:
Whenever I try to maxed out the volume and play something whether its a video or music, the phone just reboots right after. Though I wouldn't say it is only limited to maxing out the volume I also experience some reboots whenever I try to call and I feel like it reboots when I overwork the phone by opening "heavy" apps. Overheating??
Idk what happened but before I noticed those kind of stuff to happen in my Redmi 9. I just previously fixed it from bootloop w/o recovery & w/o fastboot due to downgrading from MIUI 13.0.5 CN ROM to MIUI 11.0.4 GLOBAL ROM.
So I was wondering whether it was a software issue or hardware issue in this case the battery. Idk if someone had ever tried this but I've watched a similar problem got fixed in youtube w/ Redmi Note 9 instead
with soldering or reheating the fuse within the battery.
Known fix: https://forum.xda-developers.com/t/fix-nokia-8-restart-problem.4458427/
Haven't tried it yet tho, but will update if it actually works on my device.
