Mi A1 has experienced a slow start in the developmental part. As the phone was supporting the Android Nougat’s A/B partition system, it hindered the development. Apart from the issue related to the launching of the phone in September, another major problem related to the release of Kernel sources was also there for Xiaomi Mi A1. The OEM took an extremely long time to release its kernel sources, which finally got released only at the end of January.

A semi-functional port of Mi A1 LineageOS 14.1 port was released in December. The ROM however, was based on the Redmi Note 4’s kernel. The kernel source was not released at that time, due to which a considerable amount of things were not working in the unofficial ROM.

It was very depressing that even the unofficial ROM was not effective for Xiaomi Mi A1 when older devices like Redmi Note 3 and Note 4 were having fully functional LineageOS ROMs. But this has become an old story by the release of an unofficial build of LineageOS 15.1 based on Android 8.1 Oreo 8.1.

The official LineageOS 15.1 was released a week ago with new changes, features, and exclusive wallpapers. For now, there’s isn’t any official support for the Mi A1. XDA senior member abhishek987 decided to go solo and has compiled unofficial builds that are stable enough for daily usage.

The developer has provided a list of hardware which works, including the important things such as RIL, fingerprint sensor, Wi-Fi, Bluetooth, camera, video recording, VoLTE, and more. It gives a clear idea that almost everything works with LineageOS 15.1 on Xiaomi Mi A1. But some users are reporting that double tap to wake and Live Display are not working currently. Anyhow, that should stop you from using the ROM now, would it?
