Has been using it since 3 months not even a single problem encountered. Multiple apps may slower the speed but it never hanged the phone. Sound quality is very clear and reception has never been a problem in the phone. MIUI is easy to use. Stylish colors and design is really cool. Features offers by the phone are useful and many are new, quick ball, 3 finger SS and many more. have an android platform so it is very easy for users. It is very reliable and durable. Updates make the phone handy. It is worth giving a shot in such price.
