Hello all,

I recently downloaded V10.3.4.0. from the web as I could not wait for the update to appear in miui. After the update my call quality is horible.

I can unlock my device today according to the unlock too, is just flashing the fastboot image enough to restore the firmware?

I would like to wipe everything and reinstall the orginal firmware so i have my original call quality

please help

Are you talking about echo sound during calling becuase of noise cancelling mic and main mic are working wrongly?
If yes, maybe you can install beta rom since it has solved in beta roms now. You can install it without unlocking your device.
Or you can wait for next stable which is expected to be release on June.

The other people I call are always complaining about the echo or the bad quality of the phone call ever since the update

For downgrade, you'll need to unlock bootloader. To switch to Beta however, you can do it without unlocking the bootloader. Just download the full ROM and flash it via the updater app. The echo issue has been fixed in 9.4.18 Beta and up. It's pretty Stable for daily use. In fact, many users prefer Beta over Stable for faster bug fixes and feature updates.

If you plan to downgrade, unlock your bootloader and flash fastboot ROM via Mi Flash tool. Do note that if you want to flash the latest stable, there is no fastboot ROM available yet. So you'll have to stick with Stable. Else, you can wait for the next Stable, but it may take a month.

Cheers! :-)

You are lucky for having only some echo and bad call quality. In my case, other people always complaining about voice breaks in the call and sometimes even calls are disconnecting automatically even though i have 4G+ signals. For getting clear call quality, i have to disconnect the call 1 2 times and then only it is working fine.

Why xiaomi not fix this heavy bugs with some kind hotfix? Users must wait month or more for complete new global version, probably fix is patch mixer config, or change fixed binary files.

The Correct question Why Dev of Xiaomi they fix it, in some beta and they broke it in other betas..... Totally not professional and very big disappointment from one company like Xiaomi.... that HUGE issue you never see it in other BIG mobile Companys... and we say Mobile because we speak about PHONE.... when you lance one phone and you make so BIG mistake with Software is like you stop to support that you sell.... because is not work correct anymore....
sorry again for my hard words but i have disappointment very much with Xiaomi.... and i have 4 phones.... and allready search to sell the 3 because of totaly bad support on software

History: Echo issue / Bad Quality Voice:

Stable Versions:
10.2.2 it was ok
10.3.4 Start the BUG echo issue / bad quality with the 2 mic cancelation

Beta Versions:
9.3.28: BUG echo issue / bad quality with the 2 mic cancelation
9.4.12:  Still Exist BUG echo issue / bad quality with the 2 mic cancelation
9.4.18: BUG ECHO and Bad Quality with the 2 mic cancelation is FIXED (we was make party :P)
9.4.25 BUG ECHO START AGAIN with MUCH more bad way
9.4.26 BUG ECHO Bad Quality With the 2 Mic cancelation is RE-FIXED (we go and we make again party :P)

Last Beta: 9.5.9 BUG ECHO START AGAIN like never was fixed...........

So the only solution right now is to DOWNGRADE to Beta 9.4.26 and stay for ever there (because after so much months Xiaomi Dev they repait the same bug on theyr Beta Roms... and they have leave one Stable Rom with that bug for months....)
