I bought this phone last month, I am very disappointed from the performance of the mobile.I bought it because I wanted an extra set only for calls, but it has also failed in fulfilling my this requirement also.The contacts automatically gets deleted and sometimes it restarts automatically between the calls.The battery backup is also very bad.The screen size is also very small. The speaker quality is not up to the mark, the sound is still very low when put on a loudspeaker.
