All I can say about mi a1 is a very good device despite of its price. You can compair this device is the value of x2 of its price. it has a good quality build. Everything's is excellent. Peopel are complaining on low lights images. But a guys know the most phones does not perform in low light. Well if u like good shoots low light better buy a digital camera.
Mia1 value for money phone and you would hardly find any other phone with this much specs in this price range.
For me I am phone tech this phone I would rate it is superb for its price a very good value
