I dropped my phone in water and it wont turn on.

Thanks heaven it wasn’t plugged into mains or you wouldn’t be here asking about your phone anymore. Save the rice for dinner, there’s plenty of good recipes online to use it and recovering electronics isn’t one of them. Unless you have some not so basic tools and skills to take apart your phone to the bare component there’s nothing you can do except finding a skillfull repair shop..it they can take care of it fast it might be saved and may be economically advantageous too. Meantime keep it away from rice and resist the temptation to check if it works..it won’t in any case :)
