This is the exact wording when I try to open the app which I downloaded and installed - "This app was built for an older version of Android and may not work properly. Try checking for updates, or contact the developer"

180° rotation is enable but the camera doesn't want to turn.

Should I change the camera app? Is there a gcam apk linked in this thread?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] frauhottelmann:
Ah you're right, the lineage camera doesn't turn around. I am using this gcam port: https://www.celsoazevedo.com/files/android/google-camera/f/changelog357/

You can also set the power button as the shutter button in Lineage cam. The ui doesn't turn, but you can reach the power button easily.

Anyone know how to make google pay work?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] Onawt:
I did a clean flash of nightly-20190925 + Gapps + addonsu-zip yesterday. I haven't enabled root access in developer settings yet and according to Play Store my device is certified. I don't use Gpay myself (can use my own bank's app to do wireless payments), but I believe that when Play Store reports the device as 'certified', Gpay should work. In other words, if you don't use/need root it seems that Gpay should work out-of-the-box.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] METZGER2017:
I thought so too but even with full stock Miui10 global freshly flashed with mi flash gpay still won't work. For me anyway. Says some rubbish like "phone has been modified"... If I remember correctly.

Just installed firmware 9.8.22, todays LOS and nano gapps. Rebooted after install and LOS starting a long time, then reboots to TWRP. What did I do wrong? Tried to reboot another time but same thing.

OK re-install without installing twrp-app fixed this.

Well I got this far.. (photo).. says to edit but I have never done this before.. what file do I edit and where is that file...?? I have google play services ticked in Magisk hide plus almost everything else except a few like es file manager, root checker, busybox ect...

I am still installing the daily Linage OS 16 updates every day.

I'm actually thinking of doing a full while and re flash and starting clean with magisk v20...

Thanks!View attachment 4844907

Seems you have installed a magisk module called MagiskHide Props Config. If you don't need it - just delete.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] juukeli:
OK, now it seems this will be my daily driver. Bluetooth audio streaming problem with my car is still here (playback dropouts occasionally), but I just invented what causes this. I have hands-free built in my car radio, and external audio streaming box that´s connected to radio (car radio doesn´t have audio streaming built in). Other phones and OS´s (including Mi Mix 2s with MIUI) can handle this setup without problems, but for some reason with LOS Mix 2s there are problems with audio streaming if both devices are connected simultaneously. If I disconnect car radio hands free bt, then audio streaming works flawlessly.

Hi,

I really don't like this encryption thing... I have Linage OS 16 on my galaxy note 4 and I see that encryption is disabled.... But it's enabled on my Mi Mix 2S. Can I disable it on my 2S and if so how...?View attachment 4845999View attachment 4846001
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
You can disable encryptation using a Magisk Module or a TWRP zip, but IMHO the issue you have is with your Note 4. Encryption protects your device from people that has physical access to the device at no cost. Why anyone wants to disable it is something that I do not understand.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] METZGER2017:
Thanks. Well whenever I want to try a different ROM on the 2S and it fails to boot first time I end up back in TWRP and I can't decrypt my files, so therefore can not restore from my TWRP backups....

I use to do this with the Samsung's, backup my phone try a new ROM might not like it then I would restore from the backup. If it failed I'd just restore because of no encryption... Just a hassle for me. I don't have anything on my phone that I would worry about people seeing..

I just hate having to flash the stock MIUI factory ROM again using MI flash after a ROM failure and loose everything in the process.

Then flash TWRP again and finally flash Linage OS 16... AGAIN...
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
I think you are flashing a ROM that doesn't supports encryption, like MIUI EU. In this case, you need to format data before reboot.

Is there a way to use this type of ROMs with encryption (you may follow this thread: https://xdaforums.com/xiaomi-mi-mix-2s/help/to-encrypt-data-data-sdcard-xiaomi-eu-t3946130)

When I finally got the Pixel experience ROM to boot up after setting it up I couldn't get mobile data to work... No matter what I did nothing would fix it. Might download it again sometime and give it another crack.

Hello all,

I'm having a hard time understanding File Based Encryption.

Steps:

- Unlocked

- installed official TWRP

- Formatted /data

- flashed official LOS

I want encrypt /data again. Whenever I chose to do it via Settings it just stalls in Encrypting phone and never ends.

Is full disk encryption supported? If not, how can I encrypt via FBE?

Sorry if it seems confusing. I'm a bit confused myself

Regards
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] tyratron:
Which firmware do you have? Global, china or EU? Also which version? You need to have at least 9.6.20 firmware either global or China. The encryption will not work with EU.

EDIT: Also you did " format -> yes (typed)" or just wipe?
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] :
Encryption isn't working on EU but it's due to vendor, not firmware
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] aurocha:
OK, in fact I tried xiaomi.EU ROM, but it didn't cut it for me, so I immediately flashed LOS, which provides a vendor image. Thought that'd be enough.

I have xiaomi's official vendor from latest stable as well as the latest firmware which I'll flash when I arrive home, as I'm currently working.

I'll report back later.

Regards and thank you

I have read somewhere LineageOS will not boot if you use the stock Vendor image instead of the one supplied with LineageOS.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] ToldYouSo:
Just FYI for those using the EU firmwares... Version 9.9.3 is the last one where Voice match is working. Other things break too in newer version. Xiaomi tells us it is because of Chinese based firmware and incompatibility with SD845/855 but this post proves that is fixable easily if only Xiaomi would listen. Too bad the stable and now also MIUI 11 eu version are broken yet again.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] aurocha:
Hello,

Flashed vendor from latest stable+latest firmware and reflashed LOS+opengapps pico.

Everything's working now.

Best regards

********(Sigh) so glad I'm running official LOS in my device. Props to the dev.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] ToldYouSo:
Vendor is included in LOS nowadays and replaces the Xiaomi vendor image. Only firmware is needed.

---------- Post added at 15:06 ---------- Previous post was at 15:01 ----------

And by the way EU version can run both encrypted and decrypted. Flashing this will ensure data stays decrypted. Otherwise it will probably boot encrypted if Magisk is not flashed before 1st boot.
[Xiaomi Mi Mix 2S ROMs, Kernels, Recoveries, & Othe] aurocha:
Thanks do much for all the information. I personally see no point in running unencrypted, but that's for each one to decide.

As for running xiaomi.eu's, sure, that's what I'd pick if LOS wasn't available. I'm missing a few ROMs like Omnirom on this device. Or even PA.

I'm experiencing a small bug: when a phone call ends and you take the phone away from your ear, the screen doesn't automatically turn on which is both annoying and odd.

Anyone having the same problem?

Can’t control vibration intensity

Can’t find vibration intensity in Settings or Kernel Adiutor(root). But third part apps’ can be controlled (such as Gboard).

Idle battery drain

Is an idle battery drain of ~2% per hour a normal value for this phone?

I'm currently using the 2019-10-20 LOS build with the global 10.3.6.0 firmware (stable).

The global 9.6.27 firmware (weekly) with the LOS builds starting from 2019-09-18 produced similar results.

I don't remember what it was like with the 2019-08-07 LOS build.

With mobile radio enabled (connected to 4G) I get an idle battery drain of around 1.5% per hour.

When the phone is in airplane mode (so with 2G/3G/4G disabled) but with WiFi and Bluetooth enabled, I get a battery drain of around 0.5% per hour.

Attached is a picture of my test (merged 3 screenshots into one):

Left: 11 hours idling while connected to 4G and draining 16%.

No apps have been using up the battery while the phone was idling.

-> Draining ~1.5% per hour (16% / 11 hours).

Center: Additional 11 hours with mobile radio disabled but still connected to WiFi and Bluetooth and draining additional 7%.

No apps have been using up the battery while the phone was idling.

You can see there is a significant change in the slope of the battery usage curve at the 11 hour mark.

-> Draining only ~0.6% per hour (7% / 11 hours)

Right: Screen usage is at 11 minutes for the overall 22 hour duration, so the battery drain was not affected by the screen too much.

I just updated to the latest LinageOS 16 image of 29th October (have 16 running since May this year and never had issues) by the updater function. Now the WiFi can't be turned on anymore. Any advice what I can do? Currently I have no internet access anymore.

Also, I'm not capable to make Magisk (root) working with this ROM build (tried Magisk 20.0 and 20.1 and Magisk app says Magisk is installed but when apps tries to receive root permissions the permissions are denied after a while and no log info into the Magisk log).

Hopefully the Mix 2S follows soon :).

Edit:

[MENTION=455439]bgcngm[/MENTION]: The Mix 3 has the same chipset (845), doesn't that make these updates also suitable for our Mix 2s?
