I purchased SONY XPERIA J mobile set three months before. Suddenly it started vibrating. Service center made it a liquior damage case just to earn money and said 1 hardware part will be replaced and phone will work fine. 3 days later, they said motherboard need to be replaced and I need to pay 70% amount of mobile purchase, although my phone is under warranty and it is not water damaged phone (said guaranteed)
I am not satisfied with sony's customer care service. Purchasing sony is really a worst option i think.
