If your iPhone is showing incoming calls on the screen but not ringing, you are not alone. This no ringtone sound issue is very common on the iPhone 17 series as well as older models, and in most cases, it is caused by a simple setting or system behavior rather than a hardware problem. Below is a complete, human-written, high-SEO guide explaining why this happens and how to fix the caller sound issue step by step.
Check Silent Mode, Do Not Disturb, or Focus Mode
Many users forget that Silent Mode or Focus is enabled. First, check the Ring/Silent switch on the side of your iPhone and make sure it is not set to silent. Next, open Settings, tap Focus, and ensure Do Not Disturb, Sleep, or any custom Focus mode is turned off. If Focus is active, calls may appear on screen but the ringtone will not play.
Turn Off Attention Aware Features (Important Fix)
Sometimes the iPhone reduces ringtone volume automatically if it detects your face.
Open Settings, go to Face ID & Passcode, find Attention Aware Features, and turn it OFF. This fix works especially well if your phone rings very softly or seems silent even at full volume.
Use the Side Button Properly on iPhone 17 Series
On the iPhone 17 series, Apple has refined the side button behavior.
Press and hold the Side Button, then toggle from Silent to Ring mode. This helps resync the hardware switch with system sound settings and often instantly fixes no ringtone sound problems.
Check Sound & Haptics Settings
Open Settings, tap Sounds & Haptics, and adjust Ringtone and Alerts volume to a high level. Enable Change with Buttons so volume keys control ringtone sound. Also, set Haptics to Always Play to ensure vibration works even if sound is low.
Disconnect Bluetooth Devices
Your iPhone may be routing call sound to a connected device.
Go to Settings, open Bluetooth, and disconnect or turn off Bluetooth temporarily. Devices like AirPods, wireless earbuds, car Bluetooth, or external mics can cause ringtone sound to play elsewhere instead of the phone speaker.
Disable Silence Unknown Callers and Check Blocked Contacts
Open Settings, go to Phone, tap Silence Unknown Callers, and set it to Never. Then open Blocked Contacts and make sure the caller is not accidentally blocked. This setting is a major reason why calls come without ringing.
Force Restart the iPhone (If Nothing Works)
If the issue still persists, a force restart can clear system glitches.
Quickly press and release Volume Up, quickly press and release Volume Down, then press and hold the Side Button until the Apple logo appears. Release the button and let the iPhone restart fully.
This complete guide helps fix no ringtone sound for incoming calls on iPhone 17, iPhone 17 Air, iPhone 17 Pro, iPhone 17 Pro Max, as well as iPhone 16, iPhone 15, iPhone 14, iPhone 13, iPhone 12, and iPhone 11. These methods cover all major software, settings, and system causes so your iPhone rings loudly and reliably again.
