I can say Mi A1 is one of the best budget smartphone in the market .It has duel rare cameras which takes really great images and portrait mode and bouquet effect.I myself is using Mi A1 smartphone and is very happy with its pure android .It has a decent battery life.It also supports usb type-c and provides great sound output but I am only disappointed with its front camera which is only ok and it also have thick bezel. It has good build quality which looks similar to apple iphone .I am using it for 2 months now and it is running butter smooth , I am not having any lagging issues because of 4gb ram and no storage issues as per my needs.
