My wife dropped her iPhone 5C in the toilet for a max of 2 seconds (no case) I dried it as best as I could and put inside a bag of rice for more than 36 hours. Home button and sleep button works, camera works, speakers work great, also charging fine and it doesn't overheat (yet) only problem is the screen is very unresponsive. Lags a bit while moving between pages and sometimes when I push on an app it won't open or start to shake. Slide to unlock also unresponsive and sometimes reboots. Can it be savaged or should I just dump it?
