Call problems

I ordered my Mi Max 3 from TradingShenzhen and chose the option to have them install the xiaomi.eu ROM. It arrived with TWRP installed, an unlocked bootloader, and xiaomi.eu MIUI 10 v. 8.7.26 installed. I downloaded the most recent xiaomi.eu MIUI 10 ROM (v. 8.8.23) and flashed it in TWRP.
Everything on the phone is working fine except for a persistent problem with calls. Within about 40 seconds of being in a phone call (whether on the phone or through the car's bluetooth) the party on the other side complains that my voice has suddenly changed to being very "tinny" and "robotic" and that they can't understand me. I hear them fine. At all times my signal strength is excellent. Depending on where in the city I am I may be on LTE or LTE+ with four or five bars but the problem persists.
Does this sound like a firmware issue or did I get a bad phone?

Try this fix from @ice0901: Hey I fixed it. Found a post on a thread that will enable VoLTE on Xiaomi Phones. Apparently they disabled VoLTE starting with MiUi 9 due to lack of certifications in certain countries, the US being one of them. To activate it dial *#*#86583#*#*

Thank you for your note. I used the secret code and activated VoLTE, but the problem persists. I called my telecom this morning and a few seconds into the call with tech support the chap said: "your voice has become distorted - I can't hear you" and then he hung up! I was thinking about using fastboot to flash the China Stable and then reflash the xiaomi.eu to see if that clears up the problem, but I am concerned about the announcement that beginning with MIUI 10 v. 8.8.23 "anti-rollback" has been activated on the Mi Max 3 and that you will brick your device if you attempt to downgrade. I also read on the xiaomi.eu forums that xiaomi.eu "disables" the anti-rollback features of the China development ROMs they use. Any thoughts on how to proceed?

Happy to help! Sorry you're going through so much headache. I would suggest starting over as you mentioned and doing the following from @omer1919's instructions from his nitrogen rom thread:
"I suggest to start clean again by flashing 8.8.9 fastboot and then follow the full installation instructions on op post
Installation Instructions:
- Make sure your bootloader is unlocked!
- Boot to fastboot mode
- Format your data to make sure that the installation will be clear using the command: fastboot format userdata
- Flash TWRP Recovery
- Boot to TWRP recovery
- Mount all the possible partitions
- Wipe your data,cache,Internal storage,dalvik DONT WIPE SYSTEM OR YOU WILL BRICK YOUR DEVICE
- Using MTP or OTG copy the xiaomi.eu rom to your device
- Flash the Xiaomi.eu rom
- Wipe cache and dalvik
- Reboot"

Can you tell us what carrier you are using? I also bout from trading Shenzen with the xiaomi.eu rom installed and had call problems at first. First thing I did was follow the advice from this thread. Flash the chinese fastboot then flash the latest xiaomi.eu rom. Then I enable voLTE by typing *#*#86583#*#* into the browser and now my calls work great!

My carrier is Telus (Canada). I followed the advice in the thread you linked (flashed China stable, re-flashed TWRP, etc.) then flashed xiaomi.eu 8.8.23 and this time my call problems were even worse. When I went to dial anyone the phone app would simply say (failed to connect). So I then flashed xiaomi.eu 8.8.9 which other Mi Max 3 users have commented is trouble free, and so far I've been making calls for the past hour to different landlines and mobiles and no call problems. Perhaps there is a problem with 8.8.23, but it is odd that more people haven't had my problems using that version.

UPDATE:
I have now had several messages from other Mi Max 3 users that 8.8.23 caused serious call issues and that reverting to 8.8.9 fixed all their problems. I have now had two days trouble free after reverting to 8.8.9 so I will wait for other reports before considering today's release of 8.8.30 (if it isn't broken why fix it). Besides, MIUI 10 beta testing is now complete for several devices so Xiaomi has begun releasing China Stable MIUI 10 ROMs as of today. I downloaded and flashed the China Stable MIUI ROM for my Mi MIX today and it is working great (despite the odd annoying menu in Chinese). Can't wait for the developers at xiaomi.eu to release their version of the China Stable MIUI 10 ROMs. If the Mi MIX (an older device) has a China Stable MIUI 10 ROM it can't be long before our Mi Max 3s get the stable version as well.

For those of you with call problems using xiaomi.eu MIUI 10 v. 8.8.23 finally an explanation from xiaomi.eu as to the cause. Xiaomi.eu has always 'stripped' the anti-rollback feature from China developer ROMs that they translate into European languages. For the Mi Max 3, 8.8.23 was the first China ROM issued with arb, so in their release xiaomi.eu stripped this feature from the firmware of the ROM. After so many complaints they realized that beginning with 8.8.23 a new modem (required for calls) was imbedded with the anti-rollback feature of that ROM, and by stripping the arb from the firmware you wound up with a ROM that included a modem that didn't work. So on this week's release, 8.8.30, they have left the anti-rollback feature in place, thus allowing the new modem in the firmware to permit normal calls. So you basically have two choices if you stay with xiaomi.eu on this phone - stay on 8.8.9 which is stable and has no anti-rollback protection, or upgrade to 8.8.30 but thereafter brick your phone if you attempt to re-flash an older version.

...then someone try 8.8.30 ? Resolved call problem ?
Can I reverse my actual rom 8.8.23 to 8.8.9 ?

First: mi global store is not official Xiaomi store, just a chinese guy, which sell Xiaomi devices from China.
Second: they unlock bootloader unofficial, which is a big problem.
In other words, you got a chinese Mi Max 3, with unofficial unlock bootloader and fake ROM. Buy official global version and anything works perfect out of box.

Plz how can I get official global ROM for my mi max 3. I am in Nigeria and bought the unlocked global version of the phone last two months, August. I need Ur help, pls

Changing the 64GB GLOBAL version to EEA 128GB.

Hi everyone,
I bought this phone two weeks ago and it came with 10.2.2.0 global firmware installed. The software version is a bit "outdated", it has few bugs and it's missing various features from china stable and even EEA firmware. Ok, minor stuff but it still pisses me off that the software isn't up-to-date like the others. So, since I can still return it and get a full refund, I was thinking about giving it back and take the 128GB EEA version, almost for the same price, due to the latest price drop. What do you guys think? The only concern I have is the possibility that EEA version could be less followed in the future.

You can install EEA firmware on your device if you think it might be better. I believe the reason global rom is slightly behind eu rom is because they were working on the developer rom which is now released, that developer rom is way ahead of any stable rom in terms of features, you won't see them in stable rom for 2-3 months.

The reason I'm still on global stable is related to retailer warranty. I would like to avoid any software problem that could compromise the warranty by flashing other stuff, otherwise I would be using miui.it rom already, or xiaomi.eu. Also, why focusing so much on global beta if the beta-program is going to stop on july first?

I have a feeling they will end up continuing the beta rom for the devices which will still be receiving the chinese beta (devices under 1 year old and no redmi devices) however they said all devices will not get it due to majority of forum users having old/redmi phones, there would be more uproar from these users if their devices were singled out. Otherwise I don't see why they would bother releasing the first mi9 se beta rom now.

That's a realistic scenario, I guess we will have the answer in 3-4 weeks.

What is the actual difference and benefit for running EEA (besides it being an european version) vs Global?
It seems like global is now ahead, but it will always be changing. Just looking for what's best

Hi.
I also have an Mi 9 SE with "just" Global ROM 10.2.2.0. What's the way to flash it to Global EEA?
TNX

I was under the impression that the Global ROM is more up to date than the EEA version? Mine has the May security patch and seems to work well.

My phone works with quirks.
Randomly, but always, turning on camera when in pocket. Phone is locked with FP+Pattern...

is android 10 god enough to update from android 9 yet?

Hello, I have been running a rooted mi a2 lite 10.0.9 for a while. I'm wondering if android 10 on mi a2 lite is good enough to upgrade to after months of its release. My current set up flashes a black screen from time to time when im in video calls in whatsapp or snapchat. I want to be stock, if i choose to upgrade i will keep the device stock(no root, no magisk, no custom kernel) , but ive heard so many problems with Android 10 that im not sure if its worth it.

There are still a tone of bugs and stability issues to be fixed, you can find more info here and here, I kinda' gave up on this device and don't use it as "smart" anymore. The problem is that most of those bugs are day1 bugs (for those who could update and didn't end up bricked). 10.0.9 isn't september update? I suggest you install the latest January Android9 patch and wait... I decided to be part of the Android 10 test and report bugs as fast as I can, so we can have them fixed... but it seems we're 6 months into Android 10 and nothing good came to this device.

What are your experiences with Arrow OS, Pixel OS or ProtonPlus, how is the experience and is it worth switching to one of the three custom ROM's?

Hi everyone, I've a Xiaomi Mi 10T Lite and I'm currently using Xiaomi.eu. Now I'm switching to another custom ROM and found 3 of then: Arrow OS, Pixel OS and ProtonPlus. Anyone using or have used one of the three, how is your experience with the ROM? Does SafetyNet work with the stated ROM's? Is if overall worth it and lastly which of the 3 is the best choice?

Im using PixelOS right now, it's stable and has good battery life, fast charging also works and SafetyNet also passes, only thing that doesn't work is LDAC / aptX, even with AAC the audio quality is not good.

Alright, thanks for the information!
After doing some research I've chosen for Arrow OS for my Xiaomi Mi 10T Lite but I can't download the newest version because the file is unavailable or removed. Does the method of flashing a older version and then update to latest version with OTA work?

I've just gotten an answer and that is that because build is unofficial the stated method doesn't work.

Question MIUI 14 Update for Mi 11 Lite 4g

Hi all,
I am a big fan of Miui, and since 2012 i am using Xiaomi devices. Currently I'm having Mi 11 Lite 4g Indian version. Even though Global, EEA, Indonesia versions got Miui 14 for Mi 11 Lite, Indian version didn't. What matters is it is not listed in Miui India official release schedule. What may be the reason?? Won't we get Miui 14 in India for Courbet??

This question is better suited for Xiaomi forums, and even then I'm not sure you'd be able to get the answer you seek since virtually all people there don't work for the firm (i.e., they know what you know and have access to the information you do).
Either way, release schedules are orientative, take them with a grain of salt, Xiaomi's software support isn't on par with some others' to be honest; there are even differences in upstream Android versions between devices released in China and their international equivalents, much more when it comes to MIUI features.
In any case, I wouldn't be surprised if MIUI 14 were released for the Indian variant at a later date, and if you are comfortable running it with an unlocked bootloader, you can unlock it and flash a Global release, for example.
