Phone has no problem, all ok but a black spot is appearing on the display. I wanted to get the display changed, but the service centre said this spot goes away automatically. Later, yes, it is fading away gradually. If you want, you can get it changed or use it as is without any problem. I use this phone for all my work myself, now I am going to buy a new phone so I am selling it. To buy it, you need to come to Hariken Road.
