Re: my phone doen't ring when i call it only works on the speaker
Try any of the following:
1. Reboot the device.
2. Make sure the "mute" switch isn't enabled.
3. Make sure the volume button is pressed to increase the volume
4. Make sure that the Do Not Disturb feature isn't enabled.
5. Go to Settings - Notifications - Phone and then make sure the "Allow Notifications" is enabled and then select a ringtone in the "Notification Sound" section.
6. If none of the above work, decide if you want to restore your device and set it up as new OR make a genius bar appointment with the nearest Apple Store to see if they can diagnose the problem for you.
