Ringtones and vibration stop working on my Nexus 5 (using Android 5.0.1) when receiving a call. There were working before, but I don't know why the ringtone and vibration just stop.
I tried different things: restarting the phone, updating the software, changing the setting ringtones, turning off-on these settings for both ringtones and vibration, etc.
Can anybody help me?
