I bought sony experia C3 dual before 2 and half years.And believe me I am very disappointed as the cammara quality is not so good as I expected but in design I would like to say that the phone is to good as it is very slim.And has very great which attack the customers to buy.The sound quality disappointed me much as sound quality has decreased and my vibration quality had became bad. There are many inbuilt features built in it which are interesting. In case of durability it has less durability estimated durability will be 4 years. In case money it has been prized little higher.
