How To Fix Muffled Sound On Lifeproof Case

Nowadays, smartphones are much more than machines for making calls. As a matter of fact, making regular phone calls probably isn't high on the list of the most performed actions on a smartphone. Especially the iPhone. After all, who needs calls with Facetime, iMessage, and other IM services around.

But even though traditional calls have lost their popularity, those who still use their iPhones for calling other people still want everything to function properly. And everything does function properly most of the time. However, some users have reported poor in-call sound quality on certain iPhone models. A problem that you'd want to resolve as soon as possible.

If you're one of those users, and I assume you are, we prepared for you some optimal solutions to tackle the distorting and muffled sound, and/or bad microphone performance while making a call.

How to improve bad call sound quality on the iPhone

In case you experience bad sound call sound quality on your iPhone, try some of the following solutions:

Disable Noise cancellation on the iPhone
Select Data Only in Mobile Data Options
Try using the phone without the case
Turn off the Bluetooth
Try restarting the phone
Try updating to the latest version of iOS

1. Disable Noise cancellation on the iPhone

Noise cancellation is a built-in option that helps you by reducing ambient noise while speaking on the phone. Good intention but some of the users found it unsatisfying. To disable it, follow the instructions:

Tap Settings.
Head over to Accessibility .
Go to Audio/Visual.
Turn the Phone Noise Cancellation option off.

2. Select Data Only in Mobile Data Options

There may be a problem concerning your Mobile Data. Maybe your VoLTE ( Voice over LTE) is the one that makes calls distorted, so try disabling it. To that follow this path:

Go to Settings.
Head over to Cellular.
Go to Cellular Data Options > Voice & Data.
Disable the VoLTE option.
Choose Data Only instead of Voice & Data

3. Try using the phone without the case

There are some reports that your case can be the issue while speaking on the phone. Because it covers the rear microphone, sometimes may cause distortion.

Remove your case and check your in-call performance without it.

4. Turn off the Bluetooth

Interference may also occur because of your headset and phone speaker. To be sure that is not the case, disable Bluetooth:

Go to Settings
Select Bluetooth
Turn Bluetooth OFF.

5. Try restarting the phone

If the problem is somehow connected to the software, the reset may be of help. To reset your iPhone, do the following:

Press and hold Wake and Volume Down buttons
Wait until the Power off screen appears.
Drag the Power off slider to the right.

6. Try updating to the latest version of iOS

Keeping your phone updated is a good way to overcome slight software issues, probably even the sound ones. To update your system, follow these instructions.

Make sure your iPhone is connected to Wi-Fi and charging.
Go to Settings .
Choose General.
Select Software Update.
If there's a new update available, tap Download & Install.
