I dropped my phone into a lake, im not too sure on how deep the water is there but i got it out after less than five minutes of it being under the water. Ive had it in rice for awhile now but it doesnt seem to be getting any better, the screen is completely fine and then it starts flashing and sometimes it goes completely black. The top right of my phone screen is basically off and ive done everything i can think of to help get the water out. Please help me!!
