RN4 MTK constant call drop & calling on its own... - Xiaomi Redmi Note 4 Questions & Answers

my redmi note 4 (nikel) constantly drop calls or calls on its own to random people while I'm
on a conversation with someone else.
it also sometimes makes me not hearing the person I'm talking to (like mute but not reversible).
I've unlocked the bootloader and tried a few ROMs, but nothing solved it.

Return it if you can. I did this and my new one has no issues unless calling VZW.
Additional question: Is this hissing only experienced during cellular calls, or noticed in other formats as well? Got a note 2 on the way but won't be able to activate it for a week or so, want to test for common problems without activating/slapping in a sim card.
Happens only during voice calls

Never had this when calling both land lines and cell phones. I'd exchange it. With a problem like this it shouldn't take more than 10 minutes (ignoring you'll have to go through settings again). FYI I had to return one and they looked for superuser in my apps drawer when I did.

[Q] Jiayu G4 - phone call problem

Hello to everyone and have a happy new year,
i bought a Jiayu G4 phone a month ago and i face a problem in calling. When i am on a phone call, the person to the other side of the call hears a noise. This noise, to help you understand, it's similar to the sound that a TV or THE SPEAKERS do when you put a mobile phone near them. This is very annoying and i can't explain why it happens. Now, in order to make the things better till i'll find a solution, i bought a bluetooth. The problem whem i'm using it, is that the person to the other side of the call can't hear me correctly. To help you understand, my voice it's like a robot's voice and it's not quite loud. Does anyone have an idea how to face that?
Thanks a lot

Do you find a solution? I have the same problem with my g4s

Redmi Note 3 Pro call quality issues with one mobile network operator. Wierd signs...

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?

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.

Help from developers needed for serious network 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%.

Bluetooth handling Android vs IOS

Hi,
First of all my apologies if this is the wrong place but at this point I think only a developer could point me in the right direction if there is one.
I spent a lot of time driving for work and I have all my family overseas therefore, Whatsapp and Skype calls are the way to go for me.
I drive an old 2007 Seat with OEM bluetooth that is controlled from the steering wheel. However due to the age is "Calls only" and it handles the phone perfectly well.
I have a Note 3 with the latest Magma NX Rom (did it yesterday) and it beautiful. My problem is this, my wife's iPhone SE handles whatsapp calls and skype calls with ease. I can accept and reject calls from the wheel. My friend's 6s too. However with my note 3 the call comes through although the Dash shows my own number calling and the call gets through and then the link is dropped after 10-15 second (not the call). I also tried it with a stock J5 and the same thing. I tried many of those BT Mono Router, Sound about etc but no difference. I also looked endlessly and wrote in different forums and no luck. This seems to be an OS issue but I find it strange that I am the only one experiencing this and more strange that there is no solution.
If anyone can think of why this happens and if there is a solution I would be very grateful indeed.
Cheers!
