Hi! I got my Z ultra a Month ago. Pretty good device. but after 2 weeks the ZU notifies me that the sd card was removed even it's not. I tried with 3 SD cards and all were burnt instantly neither my ZU nor another device recognize the card. The problem is very popular with the Xperia Z users. I don't know about the ZU. I checked the water indicator (too see if my warranty was voided) but when the phone is with the screen on, the water indicator is lightpink but with direct light is white. Do you guys think that sony will repair//replace my ZU. Here's a photo
