Xiaomi Mi A1 received mostly positive reviews. Sam Byford of The Verge described Mi A1's most distinct feature is its software that runs on stock Android and not on Xiaomi's MIUI layer. Sahil Gupta of TechRadar wrote that Mi A1's Android One certified experience along with tried and tested hardware, and dual camera capability gives you the premium feel under a budget.
The phone has been described as 'giving a resurgence' to the Android One program, being the first Android One phone to be sold worldwide, and the first Android One phone by a top-5 bestselling smartphone brand. It was also the first mid-range priced phone to feature a dual rear camera setup with a zoom lens.

At the end of 2017, Android Oreo was released and created major battery draining issues on some devices. Xiaomi claimed they were aware of the issue and said they would be working on a fix, but it never arrived.  Another issue was the dropping of Wi-Fi connections.
