[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] w520:
Yeah I noticed the same, it seems to work with no problems after you rename the audiofx folder to something else, seems to be enough to fix the issue with Viper

Except that now I have a problem that everytime I have Viper4Android module enabled from Magisk my wifi stops working and cant be turned on for whatever reason and starts working when I disable the module, didnt help to reinstall the module either. I just gave up and deal with AudioFX for now since I got frustrated enough that I didn't want to spend my night trying to find out the issue with that. Not a ROM issue though so I'm not complaining about the ROM, just something is kind of messed up with my system specifically but since I already have set it the way I like it and don't really want to or have the time to start over and try again, at the moment I'll go with AudioFX for now since with that my whole phone works without issues :D

Other than the mess I have done myself so far so good, haven't encountered any issues with the ROM yet, OP has done a good job here :)
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
Stay on topic please. This is not rom related. Keep magisk and modules issues out of this topic
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] slavke1976:
Same situation is if you install Viper4Android as normal apk. So it is not related to magisk and modules only

Galileo support?

I've noticed that this ROM does not seem to support the Galileo GNSS functionality of the 2S. Flashing back to stock restored Galileo, so there must be a necessary element to the ROM to get the chipset to see the Galileo network.

Galileo GNSS functionality is one of the primary reasons that I purchased the 2S. Is it possible to add this functionality to LineageOS 16.0 for the 2S?

i like this rom because there is onehand mode... but i cant find options to turn this mode on after clean re-flash. can someone help me out? :( [sry for English]
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Gibghost:
I tried using AudioFX that comes packaged with this ROM and it had absolutely 0 effect on the sound whether on or off. I also tried setting a whacky personal EQ that should have been incredibly noticeable and it had no effect, either. Has anyone had luck with it doing anything?

Edit: Viper4Android works great for the EQ, but it makes my ringtones and notifications extremely distorted. So I know EQ can work with this ROM.

2nd edit: Got v4a working with no distortion with an older version installed through magisk manager. I used v1.8.2 in magisk manager (most recently updated) and 2.3.4.0 with super audio driver when prompted at the terminal selection when installing.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
Coming from previous built.. can this rom be dirty flashed? You state in op that gapps can only be flashed on a clean flash? Any reason for that?

Hi. Can you update blobs from MIUI last version, for better camera? Many changes in some preview version.

Turn off one-handed mode?

Thanks for this great ROM! Just dirty flashed the 12.08 build and most things seem to work fine. I saw the System UI crashed a few times when I was changing the system accent color, but I'm not quite sure whether that's because I dirty-upgraded. I did wipe davrik/cache though.

I have another question regarding one-handed mode. I know there is a useful "hidden" feature in LOS where you can swipe left/right from Home button to activate one-handed mode. This feature is on by default, and I could not find a switch in Settings to turn it off. I would like it to be off because I use the "Settings - System - Gestures" a lot, and it allows me to 1. swipe up from home button for Recent Apps; 2. swipe left/right to quickly switch between recently opened apps. The swiping left/right seems to also activate one-handed mode sometimes, and it is a little frustrating. Is there a way to turn it off? A GUI switch or an adb shell command would be awesome.

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Gibghost:
I dirty flashed the current build over the last build and have been stuck on the loading screen for over 1 hour. Is this sufficient time to assume that something has gone wrong? If it's at all possible, what steps must I take from here to not lose all of my configuration data?

Edit: The phone still had not booted and I have since booted into TWRP to check things out. My original encryption pin no longer works and the sdcard is encrypted. Any thoughts for why this may have happened?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
I am afraid that you may have to install the newest version of twrp and clean flash the rom. That is what I ended up doing after flashing the previous built (after the same problem):silly:
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] bellgrado:
If im coming from miui 10 global stable, after wiping everything in twrp do i still need to flash firmware to get this to work?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] bgcngm:
If you can install the latest two build you're fine. If installation fails with an error, it will tell you what you need. Basically MIUI 8.11.15 vendor and matching firmware if the minimum requirement.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Onawt:
Hey [MENTION=455439]bgcngm[/MENTION],

I assume the unofficial builds will eventually become official. Are you going to be the maintainer of the official LineageOS builds for the Mi Mix 2S? I'm planning on buying this phone, but I really don't wanna use MIUI so I'll want to immediately flash a custom ROM. Preferably LOS because it's near stock. I can wait for a while, but would just like to know what your plans are with this device.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] cheppetto:
Besides my android Auto issue, i see two other issues with my device:

1) can't get the tele camera working camera2apk finds only 2 cams, tried different vendor.img unsure why it is as it is

2) Video recording, works after boot up but is broken after i took a few photos or recorded a video.

Did anyone experience the same issues?

What i did not try flashing Miui again whipping data and return to LOS on a clean installation
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] bgcngm:
Yes, I'll be maintaining this device and it will surely be an officially supported device.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Saiger:
Unless you have mi account with special unlock permissions you wont be able to unlock the bootloader right away. You would have to wait 360 or 720 hours in order to do so. Keep that in mind.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Onawt:
Yeah, I know. Which means I'll just not use the phone in that time period and I'll just keep using my old phone haha. A friend of mine only had to wait 72 hours when he wanted to unlock his Mi Mix 2, so I might be lucky as well.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Gibghost:
I ended up clean installing, too. I was already on TWRP v13 from notsyncing. Is there some conflict with the two of something?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] ltraddical:
[MENTION=455439]bgcngm[/MENTION]: anything special updated in the latest release? Or just based on the latest sources? :)

[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] slavke1976:
I cant beleive that is MIUI just so bad for you, that you would not use phone until you get unlock :)
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] eboye:
Well, for me it was very painful. So much inconsistency and unfinished feel that I barely stayed sane during the wait time. The P DP1 was the only thing that was good downloaded from MIUI server
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] slavke1976:
I understand but it seems that you ( not only you) are not ready to accept something new.

I had such opinion when coming from miui 10 to this LOS, but i try to adapt me even all is mixed. Terrific gestures in comparation with Miui.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] theandroid02:
I dont like MIUI at all. I bought this phone with the intention of installing some aosp rom. I had to wait 1 month, so painful using miui.

I have had previous experience with miui, and i didnt quite get into it ( weirds bugs, incompatibilities).
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
Strange... I believe that it has something to do with different partitioning (instead of a twrp/vendor.img difference which i thought would be the case).... the 2 last builts seem to have the same partionining, hence dirty flashing is no problem.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] eboye:
Maybe you are right, but I don't think like that of myself. I always tend to jump in to new things (even when it's in early Alpha or Beta) and if they are better than the old ones I tend to switch. MIUI IMHO is some strange attempt to make Android look and function like iOS which brings a lot of bugs.

For example, here are few things that got on my nervs almost all the time:

The notifications can't be swiped left or right to get to snooze. They left it only on swipe to right but I almost always do this when swiping to left (right handed).

The Hangouts, Telegram and SMS notifications where not working and I do you this as my primary way of communicating.

MIUI tend to kill a lot of apps in the background and I needed to manually set some apps so they keep working in the background.

CyanogenMod and now LineageOS is something I always keep getting back to. I used HTC Sense for almost a year and am seeing some benefits of using it. Then when HTC stopped supporting and updating my device in time I switched back to LOS. In case of MIUI, that was very very hard experience.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] ltraddical:
Same here.. Tried miui for a day or two to give it a chance, but i couldnt see myself using it on a daily basis. So i also put it aside for the rest of the unlock wait..

What a fresh breath LOS felt like, when i got that to run for the first time.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] slavke1976:
Me too i like switching from ROM to ROM. But i cant tell that MIUI have more bugs then alfa or beta custom ROM.

I dont know when you have use MIUI last time. Me i used 2 weeks ago and notifications on telegram and sms works well, sometimes it is boring to have all that notification on telegram that i have to mute some chats. :)

About killing apps in back ground, dont know really about that, on tapatalk if i am reading one post and i go out of app. then next time even 10h after i open tapatalk again it is on same post.

Maybe it is because i use xiaomi.eu roms, dont like this Global.

Also on this custom roms is not everything perfect. for example on this LOS auto brightnes in low light jumps every few seconds up and down.

then viper4android doesnt work. it works but we need to rename folders in /vendor

so all roms have some sorts of bugs,

Anyway, i couldnt keep my new phone in box waiting time to unlock bootloader. :)

and thanks god that we have choices of several custom roms to install on our phone. so everybody has choice.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Henkl:
Bug? I am using 2 sim cards. The second one I use for data. But the rom keeps forgetting that I use this one for data? It switches back to the first one for data after a wifi connection. After wifi connection and going outside, I must switch it back manually to the second sim again...cumbersome
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] bgcngm:
Could be a bug. I never faced it because I have data SIM on slot 1. Be smart and workaround it for now.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Gibghost:
The just released TWRP v14 brought the password prompt for decryption back for me for this ROM.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] JC-LGMS:

I test it since a week and the two last versions have a bug with traffic monitor, it doesn't showed up anything in status bar. Any idea why ?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] crucky:
I dont have any problems here with two SIM Cards and it doesnt switch automatically the Data Connection so it must be another problem ? I use your rebased Kernel source version :)

Very good rom (12.8 I mean)! But auto-brightness still strange, in the dark it rises 2-3 steps above suddenly and after a second goes to minimum again.. Magisk 18 works perfect.
