Anyone who flashed newest rom (1.9), can you tell us about auto-brightness? Is it OK or still unstable, especially in the dimm light??
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] ltraddical:
I'm not sure what the original problem was, but i just tested auto brightness and it's lowering brightness in dimm lighting and increasing when a light is pointed at it. I don't see any weird behaviour.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] vomad:
The problem is that it happens too fast, not slowly like in MIUI. And suddenly jumps 2-3 points up and down even if the light is constant (semi-darkness, for example). So please test auto-brightness for a little more?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] sjau:
How do you actually update the ROM to a newer version? I have the one from mid-december. How would I update to the lastest one?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] vomad:
You can flash newest firmware+vendor

, than standart wipes (cache/dalvik-cache/system only) and after all that flash ROM and GAPPS. Data will be safe and untouched.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] sjau:
Ok, will try - after making nandorid backup first :) Thanks
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Anderson6:
Can this method be applied when switching to another 9.0 ROM? Like switching from PE to Los?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Berlino:
No, because data-partition also contains rom settings (not only user apps)...so you would get some problems with booting or other weird behavior - different rom, different rom settings/features etc. So always switch roms doing a full wipe ( wipe system, data, cache and dalvik cache).
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Anderson6:
Ok, I see, thanks so much)

Scusate. Per installare in maniera pulita l'ultima versione del software si deve fare anche il Format data e pulire anche lo storage interno ?

Ho provato a fare wipe system, data,dalvick ,cache e non ha funzionato..

Mi dava errore 7... Che devo fare? Grazie!

Sorry. Do you also need to do the data format and clean the internal space to cleanly install the latest version of the software?

I tried a tariff system, data, dalvick, cache and it did not work ..

It gave me error 7 ... What should I do? Thank you!
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
This worked...flashed the vendor.img to vendor partition and flashed the 8.12.27 fw. But..dont try to restart immediately after that... your phone will only display black screen :eek: ..only after installing the latest los rom (and opengapps), it was working again like it should. Thanks!

latest build is running pretty good for me. However I´ve noticed one bug: The built-in "Dirac sound enhancer" doesnt seem to work with usb c headphones. 3.5mm with a usb c adapter work just fine. I am awaqy from my pc for a couple of days so I cant provide a log. Could anyone else please try to reproduce the bug and if possible post a log?

And if I´m not mistaken the preset for the" Xiaomi In Ear Pro HD" headphones is missing. There is one for the Mi In Ear Pro but these are different ones.

Hi guys. Has anyone managed to have aptX bluetooth headphones connected with aptX codec? I couldn't: despite I can select aptX it in developer settings, it resets to SBC after I reconnect or even reopen developer settings menu.

Any thoughts?

Hello,

What camera app are you using with this ROM? Results are comparable with the ones obtained with the stock miui camera?

Is this ROM capable to record calls (automatically)?

Is possible to return to MIUI after try it

Thanks
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
Look for MGC_6.1.021_Potter_v5F-san1ty.apk

That being said.. the standard camera app does not work anymore with the latest update with all of the cameras? It crashes on me, cycling through the cameras..
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] malimukk:
There is a magisk module that ports the miui camera and it works on this LOS. You can find it in the poco f1 themes and apps forums. There is a polaris verison.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
Is there a easy way to return MIUI from LOS?

Why is MIX2S not officially supported?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] malimukk:
Well, sometimes it works that I can flash MIUI back by doing the usual wipes. However, sometimes it does not boot so I have to format data. I am using LOS for some time now and not really planning to go back to MIUI in the near future
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
Thanks for the reply.

I have displayed some LOS16 videos. Is there a way to move the back button to the right?

Also,for your words I suppose is perfectly useable for the daily...
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] malimukk:
Yes there is an option to invert the recents and back button. You can as well use the AOSP Android Pie navigation style, its up to your preference.

Yes for my use it is perfectly stable, good battery and smooth. Everything works. Also as I understand, the device is close/almost ready for official support. Furthermore, it supports 180° rotation, in cases when you need it because of the front camera

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] juukeli:
Bluetooth audio streaming with car isn´t working properly with this rom either. Sound is fine first 2-3 minutes, after that it starts to drop out and stutter, same as with Pixel experience. With MIUI it worked fine, unfortunately MIUI sucks big time on many other things. Also with A2 Lite audio streaming works 100%.

Any idea what to do with this problem?

I saw that it was already posted before. I suppose I was looking for a bit more detail than "flash x then flash y" since I'm kinda new to all this and everything I find is typically pretty vague. I pieced together a few different tutorials to get the previous build to work so I wanted to make sure I knew what to do this time to avoid any serious issues with my phone.

The biggest thing I'm not understanding is how to unpack and flash the vendor.img, I downloaded it on my phone and couldn't do anything with it or see it in TWRP. Was I supposed to do this step on my computer?

Did you bother to read the error message?

It clearly specifies "developer build", not "stable build". The one you mention in the second place is a stable one and usually stable builds are much older than developer builds.

How stable is this build? Considering picking up the Mix 2s but I do not like MIUI. Is this stable enough to use as a DD? Reading through the posts it seems pretty stable with minor issues here and there. Can someone weigh in?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] M1chiel:
I think it is perfectly fine as a daily driver. I had a few small glitches during the first installation, but nothing serious. No reboots or FCs and everything I tried works, including dual sim, bluetooth ldac audio, fast charging and theming. The Gcam mod works very well and the miui ported cam produces great videos.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] bgcngm:
The glitches during the setup are not related with the ROM by the way. Open Gapps are the culprit.

Hi there, I am currently on MIUI Global 9.6.4. Android 8.0.0. Do I need to upgrade to 10.2.1 first to flash this rom? I am a little bit confused about all the different fw versions. In other threads about Android 9 custom roms, the requirements is often fw 8.x.x.. But I version 9.6.4 is Android 8, so version 8.x.x. can't be Android 9 right? So I don't know what I have to do. Thanks.

Flash the latest developer firmware (9.1.7) before you install LineageOS and you will be good to go.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Onawt:
I was confused a little bit too, but flashed this ROM successfully late last night. What you need is a developer build; (global) stable will not work. I was on an up-to-date Globab MIUI 10 build (which was released on 07-01-2019), but it refused to flash. It gave an error stating that it needs 8.12.27 firmware. Now this developer build is quite old I believe. The latest developer ROM from Xiami's website (https://en.miui.com/download-343.html) works perfectly fine as well. Don't mind the version numbering btw; MIUI version has nothing to do with the actual Android version. It's really confusing, but it is how it is.

The only things that are actually required to be updated are the latest developer firmware and vendor.img. Those are installed when you install a developer ROM as mentioned above, but there are alternative ways to install those two components as well without having to flash the entire ROM:

This is a website that uploads firmware for Xiaomi phones by extracting the right files from official Xiaomi servers and packs it into an easy TWRP-flashable .zip file: https://xiaomifirmwareupdater.com/

It's an open-source project. Their code is on Github as well. Have a look at it. It's a pretty neat project.

Now there are normally three ways to flash a MIUI ROM:

1. Flash it using the already installed MIUI ROM, the easiest way

2. Using (Xiaomi) recovery

3. If for whatever reason it's not possible to flash the ROM with either method 1 or 2, it's possible to flash MIUI in fastboot mode. Xiaomi therefore also publishes fastboot flashable ROMs. Those are different than the recovery ROMs that they publish.

The website provided above also has links to download fastboot flashable developer builds. For the Mi Mix 2S this is currently the latest fastboot flashable version available: bigota.d.miui.com/9.1.24/polaris_global_images_9.1.24_20190124.0000.00_9.0_global_373af64e51.tgz

Download it, extract the .tgz file, open the .rar file that's inside and look for "vendor.img": extract that file.

Now you'll still need matching developer firmware. Currently this is the latest version available: https://github.com/XiaomiFirmwareUp..._miui_MIMIX2SGlobal_9.1.24_813047aece_9.0.zip

Copy + paste the vendor.img and the firmware zip file to your phone. Instal the .zip file the way you would normally install a ROM. Flash the vendor.img by installing it to "vendor partition". This way you update both the vendor.img and firmware to the latest 9.1.24 developer build.

If done successfully you can now flash LOS16.0 + OpenGapps or whatever else you want to flash. Hope this post clears things up a little.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] toxicbrain:
Hey, thanks for your help. I really appreciate it. I give a try! Another question: which TWRP version should I take? Thanks!
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Onawt:
See this thread: https://xdaforums.com/xiaomi-mi-mix-2s/development/recovery-twrp-mix-2s-t3790922

Somewhere down in the fist post you'll see v15 (latest version as of now). It's still unofficial, but seems to work fine for the basic things it's used for. Hopefully this will become official at some point. To flash do the following:

1. Install fastboot + adb drivers from here, the first post explains everything: https://xdaforums.com/showthread.php?t=2588979

This tool hasn't been updated in a while, although it still worked fine for me. A more up-to-date tool which you can also use seems to be this one: https://xdaforums.com/showthread.php?t=2317790

2. Boot to fastboot on your phone (Hold Vol-down + Power at the same time with the device turned off)

3. Connect phone to PC (wait for Windows to install drivers if it is the first time connecting in fastboot mode)

4. Copy the recovery.img to the same folder where adb and fastboot are located (usually C:\Users\*User*\adb if on Windows)

5. Open cmd in the same folder where fastboot and adb are located

6. Type fastboot devices If it outputs a serial number (associated with your device) then you're connected succesfully. If not, you're either not in fastboot mode or drivers aren't installed / phone is not detected by your PC.

7. Type fastboot flash recovery recovery.img where "recovery.img" is the name of the file you want to flash to the recovery partition

8. Type fastboot boot recovery.img to boot to recovery

At anytime if you want to enter TWRP hold Vol-up + Power at the same time when the phone is turned off.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] toxicbrain:
Cool! Thanks for help.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
Thanks for your reply. Magisk is a temporary solution, it can be detected. I wander the boot.img in your ROM can be replaced or not? I tried to unpack the boot.img, without change anything and repack it, make a new ROM zip file with the new boot.img, then flash it. After rebooting the system, it always stucks at the fastboot screen. I used several unpack/repack tools which were found on XDA developer site and github. I just can't figure out what's the problem here.

[MENTION=455439]bgcngm[/MENTION]

Some thing I've noticed/discovered on the latest build. Some might not be LOS or device related so excuse me if this is the case.

- Snap is super duper basic. I know there are mods like Gcam, MIUI cam course, but this would require flashing extra zips. Will Snap support double back cameras and rotate images on the front camera automatically? Will features like HDR and manual controls (ISO, exposure, maybe even RAW?) be supported?

Don't know if this is related to Snap or the camera API so don't pin me on it. Also don't know if the missing support for it is due to the fact that LOS16.0 in general is still incomplete or if it is device specific.

- "Android Setup" kept having problems with Google Play Services (using OpenGapps pico 2019-01-26). Notification wouldn't go away and the only way to stop it was to force close the app. On rebooting it would appear again. This started happening when I had no SIM card inserted and no Wi-Fi connection on first boot. I changed all my settings to how I wanted and then I connected to Wi-Fi. This is when the problems started happening. After I did a clean install again and this time did connect Wi-Fi during initial setup, I had no issues. Don't know if this is an issue of LOS or OpenGapps. Just throwing it out there.

- Somewhere in the gesture settings there is no option to pulse notifications when doing a hand wave. This is a feature that is available on my old Xperia SP. Will the be added at a later time? I know the Mi Mix 2S has the hardware for it, so that isn't an issue. I don't miss it that much, since there is double-tap-to-wake and fingerprint sensor of course, which is something my Xperia SP doesn't have. Besides fingerprint or double-tap-to-wake is way faster. Maybe other people might want is as well. No hard feelings if it won't be added.

Question: Under "Live Display" in the Display settings, what colour profile should be used? Options are 'Default' and 'sRGB'. None is selected for me. Which option gives the most accurate colours? As far as I know sRGB is for 'compatibility'. Is that really the case? What is the colour space of the display anyway? I'm fairly certain it doesn't meet the DCI-P3 or AdobeRGB standard or something like that.

EDIT: I forgot to add. I can't format /data to f2fs, only ext4. Is this a TWRP limitation and/or does LOS not support it? On my old Xperia SP f2fs is supported and I'd like to make use of it on a modern device like the Mi Mix 2S as well, since f2fs is better suited for flash storage than ext4.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] daniel_eh:
My understanding is that it's best to just flash the latest developer build of MIUI 10 based on Android 9. Then go from there to put this ROM on your phone. I think all the firmware and vendor.img flashing mentioned in some comments is if you're updating from the previous version of this ROM, not switching from MIUI.

Hopefully someone will clarify, but I think that's it.

Anyone else noticing after update that the built in night light feature was missing? I had a schedule for the warmer color over night, but I couldn't find the Night Light in the notification shade or the full settings menu.
