Fortunately, the iPhone speaker not working has some quick and easy fixes without even visiting an iPhone service shop.

In this guide, you will discover why your iPhone speaker doesn’t cooperate with you on calls. Also, you will learn how to fix it without an iPhone speaker repair or replacement. Let’s get started, shall we?

Reasons Your iPhone Speaker Not Working During Calls

Let’s understand the possible causes behind the iPhone speaker not working on calls. Identifying the real reason will help you get the right solution without wasting time. Here’s why your iPhone speaker may stop working.

• Software bugs or incompatible updates can trigger speaker malfunctions.
• Also, incorrect audio settings can lead to conflicts and speaker outputs.
• If your iPhone has been exposed to water, the speaker may be physically damaged.
• Dust, lint, or other debris can obstruct the speaker grills. So, you may not hear any sound during calls.
• Sometimes, the iPhone can get stuck in Bluetooth or headphone mode. Hence, it might redirect audio to another device instead of the built-in speaker.

How to Troubleshoot iPhone Speaker Issues During Calls?

Now that you are familiar with the underlying causes, let’s check out how you can fix the iPhone speaker not working on calls.

1. Review Your iPhone’s Settings

The first fix is to check your iPhone’s audio settings. For instance, here are a few things you can do:

Turn Up the Volume

This might sound strange, but ensuring that your iPhone’s volume is at an audible level. So, use the physical volume buttons on the side to increase the volume. Alternatively, you can access the volume slider from the Control Centre to turn the volume up.

Turn Off Bluetooth

Is your iPhone connected to a Bluetooth device? Then, the call audio will be directly routed to that Bluetooth device instead of the speaker. To check this, iPhone Service experts suggest the following guidelines:

• Access the Control Centre.
• Then, spot the Bluetooth icon. If it’s blue, then the Bluetooth is on.
• Turn Bluetooth off by tapping its icon. Also, you can navigate to Settings → Bluetooth to tweak it off.

Look for ‘Do Not Disturb’ Mode

Reportedly, your iPhone’s ‘Do Not Disturb’ mode can interfere with call sound. So, you should check it out before deciding to go for an iPhone speaker replacement.

• Go to the iPhone’s Settings app.
• Afterwards, tap on Do Not Disturb.
• Make sure that the Do Not Disturb mode is off.

Turn Off Silent Mode

Have you turned on the phone’s mute switch by mistake? Then, it may silence calls, including the speaker. Hence, flip the switch and verify that your iPhone is not muted.

2. Restart Your iPhone

Sometimes, temporary glitches can interfere with your iPhone’s audio settings. And nothing will work better than a quick restart. Before you reset iPhones, try restarting the device. Here’s how you can restart an iPhone.

• Hold the Power and any of the Volume buttons at the same time.
• Release them as soon as the power slider appears.
• Then, drag the slider to turn your iPhone off.
• Now, wait for a few seconds before turning on your iPhone. To turn it back on, hold the Power button until you see an Apple logo.

3. Inspect the iPhone Speaker Grill

Is your iPhone speaker still not working during calls? Well, it can be a sign of blockage or even physical damage. For example, you might have damaged the iPhone speaker if you dropped the device into water.

Check for Debris or Dirt

It’s not unusual for dirt, dust, or lint to block the speaker grill. And it may cause audio trouble. For a quick clean, you can use a soft dry toothbrush to clean the speaker grill. Be careful not to push debris further into the speaker.

Examine the Speaker for Visible Damage

Also, physically damaged speakers won’t give out the expected output. So, check the speaker area to see if you can identify any visible damage such as cracks, chips, or anything else. If you suspect physical damage, then a professional iPhone speaker repair is the only way out.

4. Update Your iPhone Software

Often, software updates contain bug fixes to resolve issues like your iPhone speaker not working on calls. So, ensure your iPhone runs on the latest version of iOS.

• Start by opening Settings and tapping on General.
• After that, select Software Update.
• If you find an available update, tap on Download and Install.

Updating your iPhone can take several minutes. Ensure your iPhone has enough battery to complete the update. Additionally, connect your iPhone to a strong and stable Wi-Fi network before an update.

5. Review Audio Settings

Chances are something is wrong with your iPhone’s audio settings. And that might be causing the inconvenience of the iPhone speaker not working on calls. However, iPhone Repair Service professionals recommend checking the following settings:

• Start by checking Call Audio Routing. First, navigate to the Settings app.
• Then, scroll down to accessibility and tap on it.
• After that, tap on Touch, followed by Call Audio Routing. 
• Make sure that the former setting is set to Automatic.

Additionally, check hearing devices. Do you use any kind of hearing aids or other devices? They must not be connected to your iPhone, rerouting the call audio.

6. Test Your iPhone Speaker with Other Apps

As already stated, the iPhone’s speaker might be troubling you during calls only. Otherwise, the iPhone speaker may work fine with other apps. So, test the iPhone’s built-in speaker by playing media.

So, you can open the Videos or Music app and play anything. See if you can hear the sound. In case your iPhone generates the right audio output, then the issue might be specific to phone calls.

7. Reset iPhones

Have you corrected all the audio settings, and the iPhone speaker is still not working on calls? Then, it’s time to reset iPhones. Sometimes, a reset can resolve software-related problems. Make sure you reset iPhone settings only, not data. Thus, you can fix potential glitches and reboot the system.

• Begin by tapping on Settings.
• Next, go to General and find Transfer or Reset this iPhone.
• Afterwards, choose Reset and select Reset All Settings.

Now, it will reset your iPhone settings, not your data. Once your iPhone restarts, see if the speaker problem persists.

8. Seek Professional Assistance

If none of the above solutions work, your iPhone speaker might have sustained hardware damage. The only way to revert it is to opt for an expert iPhone speaker repair. An iPhone service technician can diagnose your device. Perhaps an iPhone speaker replacement might help.

If your iPhone is still under the AppleCare+ warranty, then you can check with the Apple Support app. Otherwise, you can contact a reputed iPhone and mobile service provider after you have performed all the troubleshooting steps.

Preventive Measures for the Future…

After the speaker works fine after an iPhone service, make sure you keep it clean. Also, use a good case. Avoid exposure to moisture. Ensure you use certified accessories and handle the device with care. In addition, keep updating iOS regularly.
