I just bought my Sony Xperia Z1 2 months ago!
..and I tried it underwater once (obviously you'd have to try it out)
Ever since then.. My Volume Down button is jammed my Power button gets jammed sometimes.. and the screen won't turn on! Also, whenever I place in the charger it vibrates continously!
I think water might've entered the phone..
I used it underwater in 0.5 m and about 10 minutes!
Any Help?
Side note:I till have my 1-year Warranty.. but I am afraid that my data and contacts are all going to get erased!
..and I can't transfer anything on to the PC~!

Open the flaps and look if the marker is red or pink.
I did.. It's red!

..but If they do by any chance "Fix It" then will all my Pictures and Contacts get erased~!
I cannot assure you that they will or won't.You need to ask them yourself.
Thank you, for your help~! 
For the future.
Try and set so that all pictures that are taken are saved on the Micro sd card wich you can remove.
I try and save all my work on the sdcard. However since kitkat there are sd card problems.
If you would have done it like that, simply remove the sdcard and there you go, all pictures are on there 
Anytime.
The above suggestion is helpful.
I have done that.. but some pictures haven't been transferred cause It turned off as soon as I took an underwater video!
