Everything has worked fine with my phone for a while, but just today I noticed I had a couple missed calls. Curious as I had the phone on my desk and never heard it ringing. So I call m phone myself and hmmmm no audible ringtone. It is not set to silent, my speaker still works, I have a ringtone set. I tried turning it off and on and still nothing. Once in a while I will hear it ring once, then nothing after. All other sounds work Anyone else have/had a problem like this?
