I went running with my iPhone today and during my run, Voice Control kept popping up and interrupting my music. Now, an hour later and without headphones plugged in it is still popping up every few seconds. Also, when I press the lock key, sometimes it locks but sometimes it takes a screencap and the home key sometimes responds and sometimes doesn't at all. I've tried a soft reset. What else can I do?

I am not sure what a soft reset it but if it is a software issue than you should be able to just restore your phone or it could be a hardware issue like your home button could be stuck.
