Hi, I bought a Sony c5 ultra dual in Nov 2015. Right from the beginning I am facing problems of some photos turning opaque grey shade either within a few hours or in next few days. sometimes even after it happens. I have read and all that is available on the net. changed the photo storing location from sd card to internal memory, clear data of album restart the phone, factory reset. then given to Xperia care, they kept device for 12 days still did not solve it. I took it again this time they kept for more that 20 days. I received the device a few days back, the problem was not solved so I did a repair using the Xperia pc companion. but even after that today one photo got partially greyed I just don't understand why is this not getting solved for more that 1 yr now. anyone please suggest permanent solution Thanks.
