Had phone in pocket and went in ocean. It was fully submerged.waited an hour and got rice.left it in for 3 days, then turned it on and didn't work.took battery out and left in for 1 day then let it charge or 10 mins and turned it on. The apple logo came on and flickered and vibrating pulse couple of times then did not come on. What should i do?

Get a new phone, or ask for a replacement if you have a warranty.

Sell it for parts.
the rice trick doesn't work on iphones.
and apple won't replace or repair water damaged iphones.

  • Iphone 4 turns off with battery left? My iphone shuts off with plenty of battery left. It only comes back on when i connect the charger. It turns on as if it had zero battery but when the home screen appears, the battery icon is at 70% (for example). If i disconnect the charger the phone dies again immediately. When I try using the phone with the charger connected, I'm not connected to any network, i can't call anyone, visual voice isn't available.
  • Dropped my iPhone in toilet, put it in rice, started working the. It turns off again? I've heard I can get a new iPhone for free at the apple store. My friend got here for free. Anyways when the phone was on, there was blue lines on the screen. So will I get it for free or? Btw I still have warranty
