Now I am using yu yunique mobile. in starting time it was running very smouth and brillient. but after fue month it created some problem like hangging problem.i think it is a cause of low ram -1 Gb ram.and it sound quality is not so effective and its display brightness not comfortable in sun light.in all negativity it has good quality of camera.yes it has 8mp camera that can able to hit any other 8mp camera.some time it’s getting heat a lot.i am using 4g sim and when I use 4g internet, this device always creat heating problem.so if you want to buy yu mobile - go with 2gb ram or higher.
