Xiaomi mi a1 is the best android one device. I bought this smart phone on a offer in flipkart for 13000 rupees and it’s worth your every penny you spend on this device. My previous smartphone redmi note 4 also have same specifications but the performance of mi a1 is amazing and the most promising features are dual camera and Android one update. It’s camera performance are amazing especially the portrait mode, battery backup is pretty amazing for a 3000 mah and the call quality is also good. Worth spending your money
