My phone was covered in in a beach bag yesterday but got too hot still from the sun. I took it out and put it in the shade to cool down after which it worked fine. I then took it in the water (salt water) to take some videos. I i understood it was water resistant up to 1.5 meters or 5 feet, i submerged it virectly down 6” trying to get a cool shot. I’ve done this is freshwater before with no issue. After about 2 minutes the screen became inactive. As there was no cellular reception the phone quickly hit 20% battery and quickly lost power from there. As soon as it hits 10% it loses about 1% per minute (all the time, not just yesterday). As we got back to the hotel I plugged the phone in for an hour and went to dinner. We came back and there was no charging icon on the screen and no blinking light on the top. I turned it on and it started making this alarming sound and vibrating with no screen. Almost sounds like an amber alert has been issued.
Things I’ve tried:
* rinsing it under fresh water
* soaking it in fresh water
* rapidly plugging and unplogging the charger cable to clean the ports / pins from any salt residue
* holding down power button for 30 seconds - 2 minutes
* holding down power button + volume down button for 30 seconds - 2 minutes
* holding down power button + volume up button for 30 seconds - 2 minutes
* holding down power button + volume down button + power up button for 30 seconds - 2 minutes
* searched this entire form and others for like situations and answers
* Tried multiple cables, charging blocks, wall outlets. all cables and charging blocks work on other devices but mine so power is not an issue
