Home button completely useless after update.
Hi, I updated to iOS 7.1 on my 5s yesterday and since then my home button has gradually lost its ability to function. At first, Touch ID was the only thing that didn't work. Then, waking the phone from lock didn't work. Now, it has completely lost all function and I can't even exit apps using it and have to reset EVERYTIME. This is my first iPhone so I'm a bit unsure as to what to do so any advice would be greatly appreciated :)
