Ipod touch 5th generation unresponsive
My Ipod touch 5th generation which is maybe only two years old is mostly unresponsive to touch. the screen will still turn on when I press the sleep button but the slider will not respond to my touch so I cannot unlock it. I still get alerts and the alarm still go's off. I also have a virtual home button and some functions still work when I tap it, like Siri, but nothing else will respond. I cant force reset because of the home button being broken. I was playing a game when it happened. The screen froze so I exited the game with the virtual home button and I was able to exit the game but it was still frozen as I could not open any other apps. I pressed the sleep button the pressed it again and the lock screen came up but I can not slide the bar over to unlock it and I cant slide the bar over to turn it off. Any suggestions on what I can do? I would really rather not have to do a factory restart if I can avoid it. Also I have a screen protector on it and was wondering if that could have anything to do with it? Though it has never caused problems before and I have had it on ever since I got the ipod so I don't see how it could all of the sudden cause it to become unresponsive. Also I am not sure of the specific version number of the ios but I just recently updated it to ios 8.
