On using this phone I never felt its build like a cheap device. Even at lesser price gives great bunch of features. Its a bit slippery due to its soft plastic back but still manageable.
Also MI ui is a bit difficult use initially for Android users but as time passes you become accustomed to it. Even though the camera is 13 megapixel its quality is a bit meagre. But being a budget phone its adjustable. Perfect phone for perfect price
