Hi,
i have a problem with my xperia S, when I click on the camera, the screen freeze for a second and then restart automatically, it doesn't happen all the time, but most of the time. Last month I send my phone to repair, yesterday they send it back, they reset the phone, looks like new. The first time I tried the camera it worked, the second time - until six time it freeze and restart, then I tried to play a video, sometimes it works, sometimes doesn't and sometimes it works for few seconds then it freeze again and restart. So today I send the phone again to repair, but I believe they will only reset the phone again..
Do You have an idea? 
You should have done a repair via sony update service by yourself:

If still not working,contact xperia care and give them more info on this:

The Update Service is not a solution, I have 2 years warranty, that's why I send it to repair, but anyway thank you alexdon 
Then it might be hardware related.In this case,it is better to have it repaired at an authorized sony service.
I think that in my country is no authorized sony service xD
Have you followed this link,see if you can find your "anonymous" country?:smileytongue:

Hahah, yeah.. My "anonymous" country is not on the list, so I tried:
Cannot find your country?
See all telephone numbers worldwide
and it's not even there 
And no sony shop or sony representatives around?In a shopping mall maybe?
I bought the phone in one telecommunications company, that's the way how it works in Bosnia 
Oh,I think I have had a chat with a guy from Bosnia(you named at last your country).I suggest you bring the phone back to those who sold it to you.I am sorry.
