Xiaomi Android 7.0 update

Xiaomi had a pretty bad case of the hiccups when it came to the Marshmallow update, so it may not be entirely representative to base assumptions about the Xiaomi Android 7.0 update based on its most recent update performance. Despite announcing Marshmallow was in the final stages of testing back in December 2015, it wasn’t until early April that the Mi 4, Mi 3 and Mi Note finally got Android 6.0.
In the worst case scenario, Xiaomi suffers similar problems with Android 7.0 and users won’t see it until six months after Google releases it. In the best case scenario, Xiaomi meets its timeline and has the update out in late December 2016 or early January 2017.
Best case scenario: Two or three months after Google (December 2016 – January 2017)
