Who I have the same questioned this topic

My Droid Turbo loses its ringing function and I miss a lot of calls. It does correct itself when I power down and back up, but this is annoying since it is losing the ring more often. When I go into the sound settings, the ringtone volume doesn't respond. All other notification volumes work, but not the ringtone volume. Very strange. Is there something I can do besides constantly powering down and up?
