Phone Call & Trying to Call

My phone is acting up. Someone just tried to call me but I didn't get to it in time.
It was buried in my purse and then I couldn't get the number for some reason, my phone has been sort of off-and-on. I had to take it out of my purse and put it on my lap because when I'm listening to music I forget I cannot always hear the ring. So I sometimes put it on my lap for the buzz or whatever.
