It is good mobile phone but due to poor functioning I dislike this phone.It has 3 GB RAM and large space in internal memory but it battery backup is so poor. In this phone their is heating issues. It camera is also not so good.It has primary and secondary camera but the image quality is not good.Its touch is running smooth but it has lag problem after 3hr running.when high quality play in this phone in extent of time their is also lag problem.Heating issue is main cause .
