This is the worst ever product of sony mobile. I used it in before for last one and half year but it totaly disappointed me . It has only one giga byte of ram and four giga byte of rom. Only two giga byte of rom are empty, the mobile apps takes almost two giga byte of rom. when you want to install some largest application like game application, facebook, whatsapp etc. it will always show that your fone memory is full.
So I personally don’t recommented to buy it. In many time after one year of use it will start hanging and start don’t responding.
