Z3 rebooted to factory settings while having it in my pocket, photos lost on SD card

Question

My 3 day old Z3 rebooted to factory settings while having it in my pocket. I was out for a five hours walk and have used it serveral times during the walk to take photos. They were stored on the SD card. Battery was on 73%. At the end of my trip I noticed it asked for my pin code to unlock the sim card. I used my newly set pincode for simcard and it worked fine. The telephone was set up with screenlock as well, but that has disapeared together with all my installed programs and my photos and videos on the SD card. The lock screen goes automaticlay on after 15 sec so I find it strange that I should be able to push the right buttons, in my pocket, by just walking, to perform a factory reset?Any suggestions on why and how to restore my photos on the SD card?

This was Sony's answer to my question: Sophia:  Hi, just looking into this for you won't be long.Sophia:  I have had a read of the thread and due to the low number of people posting on the forum over the past year I ca confirm this is not a common problem. If you have already tried what has been advised on that forum and the issue has not been resolved, I advise running a software repair on your handset as this is most liekly to resolve the issue yoyu are experiencing.X:  that is Sony's answer?Sophia:  Yes.X:  and what about all the lost data and picturesX:  this is not an isolated incidentSophia:  I understand that it has been experienced before but there has been an extremely low number of people who have experienced the issue, it is not a known fault. As previously suggested, a software repair is likely to resolve the issue for you.X:  how do I recover the data that has been lost?X:  I must say, I was hoping for more support, from a support chatSophia:  Unfortunately once the data has been lost, there is no way to recover it I am very dissappointed in the level of care from Sony. Took a long time to get the final reply, and it's apparently not a known fault, so it's my problem. If it's happened to multiple people, it's a fault.
