I purchase micro max A57 in January 2013. initially it was good. but as it passed three months it started troubling. specially when we talk about browsing it was very slow. being hanged many times in a day was very much going.
It was also not good in network as well. while working in my office it used to show me switch most of the time as I was always switch on. we are were having same service provider, but it was only my mobile which used to show switch off. I had to feel very guilty few times because of not getting my senior phone. As soon I changed it with lava.
