The worst purchase I made in my life. I bought 1 for my wife and then for myself after seeing the performance for 2 weeks approx. Initial 2 weeks were fine, so I bought one for myself also.
Within 2-3 weeks of purchasing my piece, the big problem started.
The BASIC FUNCTION OF CALLING WAS MALFUNCTIONAL.
At times, for both the mobiles, we had to wait a minute or two and in some cases 30 minutes or more before the call got connected. It led to embarrassing situations for me and almost lost my job because of it.
All other functions are good. But you need a mobile first and foremost for making calls. It doesn't serve the purpose.
