How to play mobile phone in underwater photography

I tried. When I went swimming with my friends, I jumped into the water with my mobile phone. The waterproof function is really strong. This machine is a serious injury without a camera shutter ... you can't operate the screen in the water, you can only take pictures in the water with a countdown.

This is (* _ _ *) hee hee that I took a selfie in the water. It's okay, right?
