The Xiaomi Mi A1 was an incredible value proposition in its market segment, the Mi A2 falls somewhat short. It takes away key features like storage expansion and universal headphone connectivity, plus it misses the mark in crucial areas like display and battery life. Affordable as it may be, it wouldn't be our default choice in the midrange quite like the A1 was.
The Xiaomi Mi A2 is a phone that punches way above its weight. A few hardware shortfalls and limited availability drop it just short of an automatic recommendation, but this is deeply impressive stuff from Xiaomi.
