It needs to be completely dry before power up.Silica gel works to a degree on my phone, the screen was able to turn on with the start-up logo but as soon it turns on it restarts itself.
I guess two day wasn't enough, especially on phones that are partially sealed, but I guess its true, not all phones are made equal when it comes to waterproof, I remember my XZ was completely waterproof, the swimming pool kind of waterproof.
Its like buying a lottery when you get a phone that fails its waterproof.
still waiting for update from the seller hahaha.
It should have had the battery disconnected because the power controller circuits aren't completely powered down even when off.
The longer it stays in that state the greater the chances the damage will be permanent. Corrosion never sleeps.
Unless it's a dedicated underwater camera or enclosure never assume it will be watertight.
Even these enclosures have extra room for water leakage. If you saw the seals in these cams you be more cautious. They usually work pretty good but they can fail straight from the box or at any time... as you have witnessed. I keep my phones bone dry in spite of their water ratings.
