Sony phones are good and reliable except for a few drawbacks. Like my phones joystick started giving me trouble since the third month of purchase. The chargers of all Sony phones give trouble. the charger pins are so delicate and thin, I bet your charger starts troubling after 5-6 months. This is because of the dust that keeps accumulating over the phones charging sockets pins. I need to clean the pins timely to charge my cell.
Besides this, there is nothing bad about this mobile. The battery backup is good. Sound is awesome. Infrared Remote function allows you to operate your PC(only certain main commands are available) if it has a bluetooth - specially while watching a movie.
Camera is good but the zoom and focus functionalities are missing. At times the image goes blurry. but there is a solution for that - SHOOT mode. In this mode, the phone captures 4 pictures on a single click. So at least one of those four comes out to be a sharp image finally.
