Unlock methods
Fingerprint doesn't work (but it is detected like normal), as AOSP does not support under-screen fingerprint sensors. Causing a very weird situation where it shows you should put your fingers on the back, centered up most of the phone.

This build also doesn't include face unlock compared to builds that include MIUI.

Display

 * The display has not been optimized for the devices it runs on.
 * Adaptive brightness sometimes glitches and goes to 0% brightness then switch back up.

Quick settings panel
NFC cannot be enabled on the quick settings panel, as it's grayed out, but it does work perfectly if you enable it in Settings.

Volume control

 * The volume control has too many levels.

Performance issues

 * This build lags every once in a while and you might need to reboot or force restart, you could try to lock and unlock it to bypass this issue.
 * This build will lag and maybe crash if you try to use the "Quickly open the camera" feature on the lock screen very quickly.
 * This build might randomly reboot.
 * Locking your phone while an application is opened might cause the phone to lag out, making you have to reboot.
 * Using gesture navigation might sometimes (rarely) cause your phone to lag, or crash the SystemUI.

Built-in applications
It includes a lot of applications from the AOSP (Android Open Source Project), but Xiaomi has added GMS (Google Mobile Services) and a few more applications such as a modified copy of Snapdragon Camera.

Camera

 * It sometimes won't work and make the phone lag and crash when you try to use it in any way (such as Instagram). A reboot will fix it.
 * The built-in camera application (Snapdragon Camera) have a feature called SAT and switching to it will crash the Snapdragon Camera and you won't be able to open it anymore unless you wipe the application's data.

Connectivity
The WiFi baseband software will sometimes crash whenever you are too far away from the WiFi router, but still detecting the WiFi you were connected to.

If you're using Bluetooth audio device to call, it'll sometimes get stuck on the InCallUI and it'll not play anything after you've called someone with your Bluetooth audio device. A reconnect will fix it.
