Xiaomi Redmi Note 4

Xiaomi’s one of the most popular and successful smartphones, the Redmi Note 4 gets LineageOS 15.0 ROM (unofficial) bringing Android 8.0 Oreo to the device unofficially. Update: Now, from October 2, 2017, another Android 8.0 Oreo based AOSP ROM, the Cardinal ROM, is available for the Redmi Note 4, getting you another option to have a run of Oreo on your Note 4.

The Chinese smartphone maker may or may not seed Oreo update to the Redmi Note 4 officially. But, it certainly doesn’t have any immediate plans for the roll out since no announcement regarding the same has been made so far.
