I There, I just buyed new sony Xperia c phone from flipcart one week ago on Monday and the phone started to not work properly just within two days.The aproximity sensor is not working as expected, few times screen automatically gets off and i cant do anything like go to the menu or disconnect call or switch on the speaker. I contacted Flipcart customer care but no help at all.They just said that i will get a call within a 24 hours but i didnt received any till date. Please help Thanks, Satish
