This product was the greatest one of sony's but it's time has long gone. It's very expensive and overpriced and there are many mobiles available which provides 4GB Ram in just Rs 12000.
Pros It has the best design and look and there's not a single mobile available in the market which can compete with it. World's best water and dust proof mobile. Other brands like Samsung are just copying Sony. Sony is a symbol of high status and everyone notices it more than I phone, blackberry and HTC etc..
Cons It's process speed is very slow compare to it's configuration. It's not compatible with Android 6 and higher version if you still upgrade you will get a few not worthy features in price of double battery consumption. Camera has a lot new functions and features but not good in picture quality as a 23 Mega pixel camera should be. The same old MH-750 earphones which they are providing since last 4 years with every mobile worth Rs15000 to Rs52000.
