Hi I purchased Sony xperia C mobile in "Mobile concepts shop" on November 2014, i paid 18000/- is waste.dead investment only.Sony brand name popularity thats it .It does not have internal memory.all buildup apps which is not useable and those apps cannot be deleted also.and the phone is struck or hang up for sometime and again we will be in tension.and will again run to the showroom for the repair.their also they take 3 to 4 days to repair and resolve the issues.it is very delicate mobile, so I m febup of this phone.and one thing speciality in this mobile means very low volume it has.
