Xiaomi’s Mi Mix 2S and Mi Mix 3 recently got their MIUI 12 update based on Android 10 in China. The devices, being more than a year old, aren’t going to get the Android 11 which is a no brainer. However, if you own one of these devices, and are wanting to try out the new features of Android 11, you just got lucky.

Xiaomi Mi Mix 2S Featured

Both the Mi Mix 2S and Mix 3 have got(via Notebookcheck) a new Custom ROM based on Android 11. The ROM is called ArrowOS. ROMs of both the devices are developed by an XDA member with username palaych. For the unware, ArrowOS is a custom ROM based on AOSP/CAF. AOSP is an Android Open Source Project while CAF is Code Aurora Forum. The ROM has a simpler UI with no bloatware and is closer to the stock android experience. The ROM has two versions- VANILLA and GApps. VANILLA is without Google Apps(pure AOSP) and the latter includes one.

Mi Mix 2S Android 11

The Android 11 build for Mi Mix 2S(codename: Polaris) is ArrowOS 11.0 with Linux Kernel 4.x. The ROM is official meaning it is constantly supported by the Developer but is currently in Alpha state. This means the ROM might have a few bugs here and there. The dev says almost everything works well in the custom ROM so you don’t have to worry about broken LTE or major glitches. Below are that’s not working as of now:

  • Encryption(disable it)
  • Wi-Fi display
  • Android Auto
  • SELinux status: permissive.

Mi Mix 3 Android 11

For the newer of the two, Mi Mix 3, Android 11 ROM is the same ArrowOS 11.0 with Linux Kernel 4.x. The codename of the device is Perseus. The developer says almost everything is working as usual. It is currently listed as an Alpha build just like the Mix 2S. Below are few bugs spotted as of now:

  • WiFi Display
  • Android Auto doesn’t work.
  • “Ok, Google” doesn’t work with display off.

If we recall, Mi Mix 2S launched with Android Oreo(8), whereas Mix 3 launched with Android 9 Pie. They got their Android 10 update but didn’t make the cut for the list of devices to get Android 11 from Xiaomi.

Hence, this custom ROM compiled by developers is a blessing for the users whose devices aren’t sure to get the next MIUI 13 in the first place.
