My tank 3 PRO fell into a pool for like 2 minutes.

The other day, my tank 3 pro fell into a pool for 2 minutes until I noticed. For some minutes, the phone still worked, until the screen stopped working. So i thought it was out of battery. So i tried charging it. Nothing happened. The next day, i noticed the camera and projector with some type of bubbles or water inside, the phone still charged, but screen didn’t work so i don’t know if anything more didn’t work. I brought it to a repair shop, but the price is high. Should I repair it? Or it can’t be repaired. Someone happens to be in the same situation?
