Hello Coolvaller, I just learnt this now...
Without waisting time lets get down to real business
So your fall fell inside a pool of water,, ow too bad, it can happen to anyone, do not panic just apply the following steps...
STEP 1: Take the phone out of the water immediately
STEP 2: Wipe the surface of the phone with a paper towel
STEP 3: If its an iphone, do not remove the battery, because doing that would void the warranty, after wiping the surface of the phone just place the phone in a bag of uncooked rice for 24 hours, it will absorb the water, bring it out afterwards and u can now switch on
If its not an iphone, ensure to remove the b3 and any oda detachable part of d fon before putting in a bag of uncooked rice...
