Hello everyone,
Let me begin with saying that i've already contacted MIUI support as well as i've searched other MIUI forums for the solution of my problem, wich is really strange to be honest.
I own an original Redmi Note 3 Pro (previously i owned a Redmi Note 3G). I use the largest mobile network operator in my country and he gives all his customers the ability to use other mobile network operators range/connection in roaming for free whenever we like. It doesn't support 4G from different vendors, so it's 3G max. This is important factor later in the story.
__________________________________________________________________________________________________________________________________________________
The phone was originally shipped with MIUI China Stable ROM wich run fine but as you know it had a lot of crap in it including adds and a lot of wierd chinese apps. But it DIDNT'T cause my any trouble with phonecalls quality.
I used MIflash & download mode to flash the latest MIUI Global Stable ROM, wich in the beginning didnt cause me any problems with phonecall quality.
HOWEVER. After 1 week of using the phone, one of the updates for Global Stable came out. Phone was updated without any problems and it run fine, but i noticed that whenever im talking with someone the quality of the phonecall was lower then ussually.
Then another update came out and it was EVEN WORSE. I thought it's the issue with the ROM itself so i patiently waited to get my permissions for unlocking the device.
I finally got it so i flashed my phone with MIUI China DEV ROM, installed TWRP and installed the latest MIUI available for my country (wich i previously used for over 2 years or RN 3G) wich also includes fixes and optimizations. HOWEVER the problem still occured.
I then started to blame my SIM Card, so i got a new one yesterday, i also did a factory reset just to be sure, DIDN'T HELP.
So to SUM UP:
Issues: Call quality is low in random calls
How does it show: Caller speaks like with a robotic voice, interference, sometimes i don't hear the caller for 2-3 seconds.
ROM STORY:
1. I purchase RN3 Pro. It comes with original china stable ROM. Phonecalls work fine.
2. I install global stable. Phonecalls are fine.
3. I install two updates to global stable - the quality of phonecalls goes down.
4. I unlock bootloader and install custom ROM along with TWRP, same issues.
5. I reflash whole ROM, clean installation, same issues.
6. Yesterday : I get new SIM card, i factory reset my system and get new updates: SAME ISSUES.
Wierd factors:
- sometimes when the problems occurs while on call, i can resolve the issue with just waking up the screen for a couple of seconds..
- problem seems to happen less when WIFI/Data usage are off
- problem seems to happen less when using headphones (Piston V3)
- problem DOESN'T happen AT ALL when i switch to other mobile operator network in roaming! It's only happening in my main mobile operator network! I would use other networks instead of mine but LTE/4G isn't allowed yet while on roaming :/
- this issue happens on both SIM CARD slots, on different SIM CARDS
I tried to reflash China Stable, however it seems that there were too many updates and one of them is causing the problem now on every ROM. There's a few topics on MIUI Official forums about that, there are bug reports about that but i doubt MIUI Devs will notice this.
Does anyone have any idea what could be causing this?

Link to random bug report about this from other user: http://en.miui.com/forum.php?mod=viewthread&tid=266620&page=1#pid4845168

hey what happened to your device?
I think my redmi note 3 pro has the same issue, call quality seems to go down where I would lose what the other person is saying for a second or two like the earphone is malfunctioning.
but the speaker works fine and signal is not an issue either
were you able to fix your issue?
I have the same problem with my phone since I remember. I got my phone around 3 weeks ago and flashed the latest Stable and Developer ROMs but the problem still exists. Like mentioned above by my friend, the quality is fine when I change to other operators in 2G, but in 3G and LTE its totally mess. I wish someone recognize this problem and fix this.

so sorry to hear that you have this issue as well
this is just unbelievable.... how can they just ignore such an issue? It's becoming a nuisance to sometimes impossible to use the phone to make or receive calls as I can barely make out what the other person is saying
Is there anyway we can complain about such issues?
Guys I found a workaround for this problem. Although it doesn't solve it completely. By this solution I succeeded making calls with much less noise and problem.
You have to turn the proximity sensor off for calls. It somehow solves the problem for now and make the calls much more understandable. Hope it helps you and get solved completely.
Me also facing same call quality issues

Same here no issues on China stable. Worse on global stable.. try typing *#*#995995#*#* wait 2sec and type *#*#995995#*#*(the same thing)again.. also go to settings installed apps find qti.supersaver open it and force stop these are like temp solution . If this helped please hit the thnx button
Thx for your sharing information but that didn't work dude. The problem still persists.
Guys I got a solution for myself. The problem actually WAS with the signal as I thought contrary. Yes, the 2G network works well because it has more strength with less range so its obviously works better than 3G. Hence, I started searching for a solution to improve the signal I get in my phone. The best thing I found was an app named "Network Signal Speed Booster" which boosts the signal you receive. Whenever I called a phone number after running this app, the call quality was PERFECT. This app actually connects you to the nearest antenna so the result is a better connection to the network provider. Please do this solution yourself and see if it works and notice the others. thx.
Thanks
Behrouz Your solution may work very well for me
I had the same problem
Thanks
My friend has issues with a Redmi Note 3 PRO speaker. He doesn't hear a conversation clearly. The person who he is talking with hears him perfect. Will "Network Signal Speed Booster" app help in this case? Some people says it's a fake program. Any new solutions?
Confirmed, Network Signal Speed Booster helps but temporary. I`ve noticed that it doesn`t matter of the network type,(4g,3g,2g), it happens only while the wifi is on.
Regards,

Doesn't work on Nougat ROMs like Lineage OS
When the wifi is off everything is fine. But I can't understand what causes the issue.

This message is addressed to software developers who could possibly help resolve this issue.
Myself and other users have been facing a terrible problem with this phone in regards to network connectivity and missing incoming calls.
Basically, my phone becomes not responsive to incoming calls when it enters sleep mode. If my phone is in sleep mode (screen off), every incoming call goes directly to voice mail. As a result, I have been missing hundreds of phone calls!
To prove to Xiaomi that this is not an isolated issue with my phone in particular, I have created a survey in the http://en.miui.com/forum to have an estimate of users suffering with this issue. So far, over 45 people have reported to have problems receiving incoming calls. At least 30 people have reported to be facing the issue in which the phone does not receive incoming calls while in sleep mode (screen off). This is the link for the survey I created (http://en.miui.com/forum.php?mod=viewthread&tid=272072).
I have tested several versions of China, Global, Developer and even AOSP ROMs. They all have the same problem. I have been missing incoming calls since the first day I bought my phone.
In addition, I found that users have reported network problems with models Mi3, Mi4, Mi5, Redmi Note 3G, Redmi 2 Prime, Redmi 1S. These links can be seen here:
en.miui.com/forum.php?mod=viewthread&tid=202489 (RedmiNote 3G)
en.miui.com/forum.php?mod=viewthread&tid=270142 (Mi 5)
en.miui.com/forum.php?mod=viewthread&tid=209180 (Redmi 2 Prime)
en.miui.com/forum.php?mod=viewthread&tid=207580 (Mi3 )
en.miui.com/forum.php?mod=viewthread&tid=200834 (Mi4i)
en.miui.com/forum.php?mod=viewthread&tid=158212 (Redmi 1S)
A user of the forum has posted a procedure that helps to reduce this issue of not receiving incoming calls. It consists of disabling the apk qualcomm supersaver and typing the code *#*#995995#*#* twice. This has to be done every time the phone is restarted. I have no idea of the mechanism behind this procedure but I guess it could help software developers to figure out a way to solve this permanently.
Thank you
Up & Thanks!
I have a same problem...
What can developers do about that? As you said, many users are suffering from this issue, plus you are experiencing it on several different ROMs. But a vast majority of users are NOT experiencing this issue. Why would two identical phones with two identical ROM versions differ in this matter? If the issue was not resolved by reflashing, only conclusion is that this is a hardware related problem and there is nothing the developers can do about it.
Has it been established if this is a problem across the snapdragon / mediatek range or just to one of them?

Well, they (devs, or xiaomi) can come out and say it's hardware related and call back the phones.

I think it's only SD related, because the first step of the fix is to disable the app com.qualcomm.qti.supersaver
Not sure if it is connected, but I never had a problem in the last 2 weeks, today I let my battery get down to 49%, when I went into battery use my I could see my phone network started to shut down at 70% battery,from what you say com. qualcom.qti. supersaver affects it , is this related to battery, if so is this the link???
After all those reports, there is a pattern that looks bad. Can anyone affected with this issue share if they're on 4G/LTE? I'm on 3G and never experienced such a problems. If we could manage to narrow down the issue, maybe there will be something we could do, but saying "I've reflashed all the roms available", doesn't help much. Also, are you using sim1 or sim2 slots? Have you tried with two sim cards or only one?
For example I can t recieve calls when I choose only 2g, when I choose prefer 3g in most cases I can recieve calls...
Apparently, the 7.3.2.0 china stable OTA fixes this issue! Sadly I can't test it right now

Just had my second episode of losing my phone network, again this happened when my phone got to under 70% on my battery.... it never happens if I keep battery charged above 70%.
Friends, I have a problem in my redmi note 3 Qualcomm.
It's only been a week since I bought this unit. As soon as he arrived, I changed the ROM MIUI 7.3.7 for global stable and gave it to my mother.
Three days later, the device simply does not activate the Wi-Fi. I have reinstalled other versions of MIUI and remains the same.
I unlocked the bootloader after that to try to make some tutorials I've seen on the internet but got no results.
Is hardware problem? please help me to solve this problem.
Already, thanks!
Note: I am using the google translator.
Same problem here Wifi appears on but does not show any available networks.

Desperate here. Have tried reflashing fastboot official roms 8.0.4 and the latest dev rom, and moving back to 7.5.2.0, but nothing works. Wifi doesn't see any networks in range. Can anyone suggest a test using the CTL diagnostics or some other method to determine if it is a hardware issue ? The phone was not dropped, and was not in heavy use, so overheating should not have happened.
Whenever I plugin my earphones, I do not see the tiny earphones icon on top and cannot hear any audio from it. It just plays audio from my phone. I can confirm this is a firmware issue as I have installed an app called "SoundAbout" and in that app, I enabled the SoundAbout Service and under "Media audio", I changed the selection to "Wired Headset (with Mic)". After this, I can hear audio from my earphones. However, as soon as I change the Media audio setting back to "Let App Decide", I can no longer listen to audio from the earphones.
This is a workaround but I did not face this issue earlier. I do not want to depend on any third party app for routing the audio through my earphones. Can anyone please advise any troubleshooting steps apart from doing a factory reset/flashing the phone? Thanks!
Model: Redmi Note 3 (Qualcomm Snapdragon)
Android version: 6.0.1 MMB29M
MIUI version: MIUI Global 8.2 | Stable [ 8.2.4.0 (MHOMIDL) ]
I have the same problem as you but with Custom ROMs, there isn't any problem
@mermade, This is my problem too. At first I thought it was hardware issue, but whenever I used a custom ROM, there was no such issue.
So, to tackle this, what I used to do was, I put the earphones into the headphones jack half-inserted for about 4-5secs. Then I would push them in completely and the audio used to be routed through my earphones.
Also I noted that this happened with earphones without mic only. The ones with mic never made this issue.
Earlier, I was having problems with Fingerprint Sensor too. I had FPC one and it just stopped recognising fingerprints. I thought my sensor had become obsolete. But, then again when I flashed custom ROMs it started working great for a while. The thing was, whenever I used to feed my fingerprints into it, it worked great for maybe upto 50 attempts. But, later it always vibrated and never unlocked the phone, nor did allowed to enter new fingerprint.
Another issue was the cellular reception. On miui stable there was no problem at first. Then I made some bad flashing ( that's only what I thought would've happened ), though I never bricked the device itself. I was getting signals on only one of the SIMs. Then flashed the modem partitions and had both the sim slots not working. Had my IMEI swept at times. After a lot of hit-and-trial, I managed to get both of my SIMs working (fp sensor still wasn't working). Now, I could use 4G and 3g networks simultaneously on the sim while earlier the other sim had to be on 2g is the first one was using 4g. I found out that the modem files of miui developer were more stable.
Currently, I'm on MIUI 8 Global Dev 7.5.23, and from the last builds, the fingerprint sensor has started working perfectly. Also the networks are fine. Now, the only problem is that if both sims are using 3g networks, then it always show the signal strengths on both networks exactly same. The signal strength bars change together. But that doesn't create any problem in usage.
The only problem with miui dev is that the performance, heating, charging rate and battery life keeps on fluctuating significantly with every weekly update. This 7.5.23 seems pretty good but sot is around 6hrs only.

Thanks for the detailed reply Not sure what changed but when I connect the earphones now, my phone detects it. I tried it like three times and it detected it all three times. I guess this is a temporary issue and is triggered by some apps/settings. I will continue to monitor for any changes. I am not having other hardware issues like fingerprint sensor/any SIM/network issues so don't really want to take the risk of bricking the phone by flashing/rooting. Thanks!
Same problem with my phone too.I don't want the third party app.I tried everything but nothing seems to help.Please help me.
As @sasukay said, push it half way in for couple of seconds and the earphones will start working normally. This was later fixed for me in later Xiaomi.eu ROM's, and never happend in other custom roms like LOS or RR.
I have the exact same problems as the starter of this thread. Unfortunately none of the answers work as a solution for me on my Redmi 5 Plus. Why haven't Xiaomi fixed this?
I've had this issue twice, and upon researching for it in XDA the solution that worked for me is to just simply plug and unplug an earphone numerous times until it finally works properly. This seems to be related/similar to the solution recommended by sasukay.
This solution also works for the issue the other way around, when the phone perpetually detects an earphone when there is none.

Thanks a lot brother. You are a lifesaver. Researched and tried many processes none of them worked. But your one solved the problem within seconds. May god bless you.
Hello everyone... i just bought a second hand poco f1 one week ago and i have problem whenever I'm charging my poco f1, suddenly the signal is going to no service/emergency only even i have a wifi in my home it's still cannot connect to internet and then with 3/5 minutes the phone going to restart it's self when i'm browsing or just leave the phone charging with the network on... but when i'm playing pubg mobile with the phone charging and the network on it's work normal, but when i'm going to browsing again the phone error again, i have change the rom from miui 10.2.3 global stable to 9.3.21 beta but the problem still same...
and today I have go to xiaomi service center in my town they just flashing the rom back to miui 10.2.3 global stable again and I tought the problem is solved when I'm checking again about 10 minutes with no problem, but they use a Xiaomi Mi Smart Power and I assume the output is low ampere, then in my house i use the original power adapter and cable poco f1 but the problem going back again....
did anyone have the same problem? or it just a software problem... should I change my rom into custom rom? or it was a hardware problem?
I hope someone could help me with my problem...
*sorry if my english is bad*
Might be hardware.
As you mentioned,

Don't ever use the phone like heavy tasking (gaming and stuff) while charging. It can cause thermal throttling on the CPU and the Battery (decreases its life) and it can cause a lot of issues.
Also you mentioned that you bought it second hand.
Did you have the official receipt or official invoice from the seller? If yes, go to a nearest Xiaomi Service Center, explain the problem that it is not software rather than hardware and let them check if there are damages. Might the seller wanted to sell the Pocophone F1 because he/she has issues with that.
