Xiaomi Mi A1 is xiaomi’s first android one smartphone. It is powered by google android one. Mi A1 is best for its stock android look and feel. Means it doesnt have any bloatware form MIUI or it doesnt have any kind of customization like custom UIs from brands.
As per android version it will always have a latest version of android. I bought it previous month and it instantly got a update. Few days back it got the Android 8.0 Oreo update. Which includes PiP mode( picture in picture which allows us to play hovering videos while in another app.
Its camera is also amazing dual camera allows it to use depth mode. Depth mode pictures looks as they clicked from DSLR.
Its battery is also decent. 3080mAh can power the phone for 6-7 hours with heavy usage.
In this price range this is one of the best dual cam phones available.
