How to Fix iOS 18/26 Beta Volume Bug? [2025 Updated]

Part 1. Why Encounter iOS 18/26 Volume Bug?

If your iPhone’s sound is unusually low or inconsistent after updating to iOS 18 or iOS 26, you're not alone. This common issue has been reported by many early adopters—and while it may seem like a simple glitch, there are actually several potential reasons behind the iOS 18/26 volume bug.

• Settings Issues

One of the most overlooked reasons for the iOS 18/26 volume bug is a simple misconfiguration in your iPhone’s sound settings. After installing a new iOS beta update, your device may automatically adjust certain preferences—sometimes even muting the device or lowering the media volume without your knowledge.

• Software Bugs and Glitches

Early versions of iOS, like iOS 18 and iOS 26, often come with hidden bugs and software glitches that haven’t been fully ironed out. One common issue users report is unexpected volume drops or complete loss of sound across phone calls, notifications, and media playback.

• App-Specific Issues

Not all third-party apps are immediately compatible with iOS 18/26, especially during early rollout phases. Many developers need time to optimize their applications for Apple’s latest system architecture and APIs.

• System Conflicts

When your iPhone is running multiple resource-intensive apps or background processes simultaneously—especially under the iOS 18/26 environment—it can lead to performance bottlenecks that impact audio output.

• Corrupted Firmware

If you're experiencing unexpected audio glitches or volume dropouts after installing iOS 18 or iOS 26, one potential culprit could be incomplete or corrupted firmware. During the update process, especially with beta versions, even a slight interruption or failure in installation can result in unstable system behavior—including issues with sound output and volume control.

Now that you know why you are having the iOS 18/26 volume bug issue. Let’s explore how to fix it!

Part 2. How To Fix iOS 18/26 Volumn Bug? 8 Fixes

Now that we've explored the possible causes of the iOS 18/26 volume bug, it's time to dive into practical solutions. These eight effective methods will help you troubleshoot and fix common audio problems—whether it's no sound during calls, muted media playback, or unresponsive volume controls.

Fix 1. Check Volume Settings

Start troubleshooting your iPhone’s audio by checking the basics first. Ensure your device’s volume is turned all the way up using the physical volume buttons on the side of your iPhone. Next, verify the volume level in the Control Center—swipe down from the top-right corner on newer iPhones or swipe up from the bottom on older models. Adjust the slider to increase the sound output.

That's it! Let's move ahead to the next potential solution.

Fix 2. Adjust Sound Settings

Adjusting your iPhone’s sound settings is one of the easiest and most effective ways to fix the iOS 18/26 volume bug. Check the Sound & Haptics settings in your device’s Settings app, and make sure the volume levels are properly set. Sometimes toggling options like “Change with Buttons” or disabling “System Haptics” can help restore normal audio performance.

Below are the steps to check the Sound and Haptics on your iOS 18 iPhone.

Step 1. Navigate to Settings > Sounds & Haptics.

Step 2. Now, adjust the volume slider under "Ringer and Alerts."

Step 3. Toggle "Change with Buttons" on if it's off.

Step 4. Check if any audio balance settings are affecting the volume.

Following the above steps, you can effortlessly resolve the iPhone volume bug. However, if this doesn't work, move to the next method.

Fix 3. Force Restart iPhone

Are you still having the iOS 18/26 volume bug issue? A force restart can resolve software glitches causing volume problems.

Follow the guide below to force restart your iPhone.

Step 1. First of all, quickly press and release Volume Up

Step 2. Then Volume Down

Step 3. Next, press and hold the Side button until you see an Apple logo on the screen.

However, if the issue persists after force restarting, you must try another method. Have a look at it!

Fix 4. Turn off Silent Mode

The iOS 18/26 volume button bug might be due to Silent mode. Checking and turning off Silent mode can often fix volume problems.

To turn off Silent mode, follow these steps:

Step 1. Search for the Silent/Ring switch on the side of your iPhone.

Step 2. Ensure the switch is not in the Silent mode.

Step 3. Toggle the switch to disable Silent mode if it's on.

If your iOS 18 iPhone is not in silent mode and you still face the issue, move to the next fix.

Fix 5. Turn off Do Not Disturb

Another effective way to fix the iOS 18/26 volume bug, especially if your volume suddenly drops or becomes very low, is to disable the Do Not Disturb mode. When enabled, Do Not Disturb can mute or reduce audio alerts and notifications, causing volume issues.

Follow the steps below to turn off "Do No Disturb" mode.

Step 1. Swipe down from the top-right corner to open the Control Center.

Step 2. Now, tap the crescent moon icon to disable Do Not Disturb.

Step 3. Alternatively, go to Settings, then Focus Do Not Disturb, and ensure it's turned off.

We have covered everything about this method. Now, let’s discuss the next effective way to fix iOS 18/26 volume bug.

Fix 6. Reset All Settings

To fix persistent volume issues on iOS 18/26, resetting all settings can be a powerful solution when other methods fall short. This process restores your iPhone’s settings to default without deleting your data, often resolving stubborn audio glitches.

Step 1. Go to Settings, then General, and Transfer or Reset iPhone.

Step 2. Tap "Reset." Then, choose "Reset All Settings".

Step 3. Enter your passcode if prompted.

Step 4. Confirm the action and wait for your iPhone to restart.

Step 5. After restart, reconfigure your settings as needed.

If you have reset all the settings and the issue continues, jump to the next fix.

Fix 7. Contact Apple Support
