I have used this mobile and I am very impressed with the mobile. It has all the features and its price is alos low. It has 2 gb ram and 16 gb internal storag. Also its internal storage is expandable. Its a budget device coming with 8 mp of rear camera.
The device has some negative things that it gets hot even in 5 minutes of usage. Also its OS is outdated and xiaomi doesnt provide fast update. So if you are medoum user than its a device only for you. You will be satisfied after using it. A budget device.
