A far better phone than the many low end Androids in the market. Sony has put in all the good qualities of Xperia higher phones and packaged it for a lower budget client perfectly to suit needs. Yes the phone is considerably smaller if you compare it to the notes and canvases.
Xperia does have an excellent interface, the 800mhz processor is more than enough to handle Whatsapp, Facebook and a couple of other apps that you would use daily.
I love the camera. Though theres no flash, this camera has helped me capture such beautiful pictures. If ur budget is around 11k, u should definitely go for this one.
