I found if the car is nearby, place the wet phone over the windscreen de-mister vent and then run the aircon through that vent. Doesn’t have to be hot air to dry it as long as the compressor for the aircon is running… Aircon dries out the air before blowing it through the cabin so you will have bone dry air circulating around the phone pulling the moisture out by evaporation. About 10 mins is plenty. Best done idling in the shade. Don’t want to sun damage the phone while trying dry it out…
No, hair dryer works by taking ambient air and heating it before blowing it out. Besides, definitely don’t want to heat up the phone. The aircon dries the air itself as part of the cooling. When using your windscreen vents you don’t have to set the temperature to hot to clear the windscreen as long as that aircon compressor is running. People just do because when you need to defog your windscreen it’s usually cold as fuck outside…
To dry the phone, set vent to windscreen, temperature to cold, and make sure the aircon indicator on. Cold, dry air.
