I can't swipe to unlock my phone or even turn it off :(
I recently upgraded my phone to iOS7 and I've been having a few screen freezing problems but the one I'm having at the moment is that my screen won't seem to unlock. All of my buttons and switches work. All I can do on the screen is swipe down from the very top to see my notifications, swipe up from the bottom to see all my other utilities, but it won't let me tap on anything, it wont let me swipe across to see anything else or change anything. I tried turning off my phone but it won't let me swipe from left to right or the other way. I've even tried asking siri to do a few things but she's not really helpful since my phone is locked. My battery is almost fully charged so waiting for it to go down might take a little too long and I'm not at home so I can't plug my phone into my computer. Any help would be very useful.
iPhone 4S, iOS 7
