Who I have the same questioned this topic

Over the last month, my S7 Edge has suddenly stopped ringing/vibrating on incoming calls.  The only way to correct the problem is to reboot the phone.

Symptoms:

- Not just certain callers, all incoming calls impacted

- Caller hears ringing and will be prompted to enter a voice message but phone is completely silent

- Phone settings: Ringtone and vibrate active, WIFI calling disabled, Biuetooth disabled, Auto-Mute disabled

- When the problem happens, phone doesn't ring *or* vibrate

- If voicemail is left, phone chimes with New Message notification

- Rebooting phone is only way to 'fix' problem

- After reboot, all calls have normal ringtone & vibrate action

- Reboot solution is only temporary, within a few hours or a couple of days, the problem returns

Any thoughts on what 'broke' on my S7 and how I can fix it?
