my phone xperia z5 went underwater and after the phone was continously vibrating, after leaving it for some time the phone was just essentially a brick, when i plugged it into the power point a flashing red light appeared and it the phone would vibrate in a 3 part sequence, ive left the phone on charge for a few hours and have tried to turn the phone on using the power button which seems to have no effect, i have also held in the power button with the volume up button for 10 seconds and still has no effect
