Xperia Z3: there's a water particle when i open the camera. How to fix it?

My phone is a legit Xperia Z3 last month I bought it. And when i came home I tried to pour a glass of water on my phone and after a few minutes the screen died. I sent it to the sony centre and after two weeks they fixed it. It was going so well good as new an I'm still brave enough to try it's water ressistant feature. I washed it and nothing happened I now guarantee that this phone is water-ressistant. But last week i checked my camera and I noticed there's a little water particle or a blurry watery little part in my camera until now. What should I do? I moved last week to Philippines but the warantee is not international it's only in New Zealand. What should I do?:(:(
