Last Year I bought MI A1. MI A1 has a unique features. It has the DSLR feature. What dslr does a1 also does. It has the background blur effect. we can use this by portrait mode settings. But DSLR is DSLR. No-one can beat them with their qualities. The picture taken by a1 is little bit of low quality. But One thing I want to tell you that at 13k rate we can get DLSR effect though it isn’t as clear as the dlsr. Picture quality nulify its quality. Now I m talking about the professor, it runs on Android one, which is cheapest stock android version released by Google.
