1. Adjust Volume Level and Audio Settings
I’m confident you may have tried using the volume up button during a call to increase the output. In case you have not, please press the volume up button multiple times to raise the audio level of the earpiece to the maximum.
Still, if you have difficulty hearing the person, consider tapping on the ‘speaker’ button to switch to the iPhone’s main speaker. You may also use a wired or Bluetooth earphone for a better experience.
A small number of users have also mentioned that they had success fixing muffled or degraded voice by turning off noise cancellation. To do this, open the Settings app → Accessibility → Audio/Visual.
Turn off the toggle for Phone Noise Cancellation.
2. Remove the Wired Earphone
Sometimes, merely removing the earphone and using the device earpiece fixes the audio problem.
Alternatively, at times, the iPhone might get stuck in headphone mode. This is a situation where your device wrongly assumes that an earphone is connected. As a result, you might not hear the other person at all.
The easiest way to solve this is by inserting an earphone to the headphone jack or lightning port and then removing it. Try this a few times. In case it does not help address the issue, we have a separate guide on how to fix iPhone stuck in headphone mode.
3. Restart Your iPhone
We often fail to recognize how excellent a simple restart is! It is a quick way to fix multiple such software issues.
To restart your iPhone, use the button to power it off. You may also open the Settings app → General → Shut Down. After a minute, please turn it on.
In case, normal restart is ineffective, consider force rebooting your iPhone.
4. Turn Off the Bluetooth
On a few occasions, Bluetooth speakers may accidentally cause trouble as well. You might hold the iPhone to your ear, but in reality, your device is connected to a Bluetooth speaker or headset and routing the audio there.
To address this, disconnect the wireless device. You may also turn off Bluetooth entirely from the Control Center or the Settings app.
5. Clean Your Receivers and Speakers
Dirt and debris are other enemies that are responsible for poor call experience. They may clog the earpiece, speakers, microphone, and even the headphone jack or the Lightning port.
To take care of this, use a soft dry cloth or a small soft brush to gently clean the earpiece grill, microphone holes, etc. You can take additional help from our guide, where we show you how to clean and disinfect your iPhone.
Do you use a rugged case, waterproof case, or screen protector that covers the top earpiece, microphone, or the speakers? If yes, please remove them!
6. Update iPhone to the Latest Software
Another helpful solution to improve the iPhone call experience is to ensure that it runs the latest version of iOS.
To update, open the Settings app → General → Software Update. If you see a pending update, tap on Download and Install.
7. Reset All Settings on iPhone
Calling can also be affected due to some settings you may have tweaked. If none of the above solutions work to fix the issue, please consider resetting all settings.
Your files, apps, music, photos, etc. won’t be deleted by this action. However, every setting of the iPhone that you have changed will be erased and restored to default. This includes Wi-Fi, Bluetooth, VPN configuration, Home screen layout, privacy settings, etc.
To proceed with this, open the Settings app → General → Reset.
Now tap on Reset All Settings → enter your iPhone passcode → tap on Reset All Settings to confirm.
At last, when nothing works, it is best to reach Apple Support. There may be physical damage in the speakers that can be examined and fixed by the authorized Apple service center.
These are the most probable solutions to successfully fix the issue of no sound during a phone call. Please let us know which methods worked for you. In case you have a trick of your own, kindly share that as well.
Sometimes, call quality is also degraded due to low signal strength. When you are in such a place with a poor network, consider turning on Wi-Fi Calling.
At last, it would be wise to give a thought to third-party VoIP calls. In case you have difficulties with WhatsApp, Viber, or Skype, make sure to update these apps.
