I purchased this phone 3 years ago. During the first year, it worked fine with good speed. But after that it keeps getting hanged. The battery drains in less than 2 hours. The camera quality is also not satisfactory. Keeps restarting and gets hots often. It has become very slow and takes lot of time to open any application. Sometimes, one button keeps getting pressed and I have no choice but to restart which takes a lot of time.
