my screen is not responding correctly to touch
my son threw my Iphone5 into the toilet. thankfully I have apple care and it was quickly replaced. However, the Phone they gave me has been having issues with the way it responds to touch. if i attempt to open messages, it will in turn open safari. I took it in to the genius bar to get checked. They replaced the display but the problem continues and seems to have worsened. Its now will open all apps by itself and slide down the top menu. Its very frustrating. I dont live close to the apple store, does anyone know what on earth is the problem? Is there anything I can do? TIA
iPhone 5, iOS 8.1.3
