This article explains how you can troubleshoot when your iPhone 18 Pro volume (audio, ringer, alerts and other sounds effects etc) keeps adjusting itself. For example, your iPhone may itself randomly lower or increase the volume. Sometimes, your phone may keep resetting the volume to the lowest volume or to the highest level. This is an important problem. This problem, for example, may cause you to miss calls.
If you have an issue with your phone where the volume appears to be lowering (increasing) on its own, then this article is for you.
iPhone volume alert problems
Please try the tips below until you fix the problem. Please make sure to check your iPhone after each step to see if the volume starts working.
Before we start, if your iPhone 18 Pro has a protective case, remove it. After removing, does your problem occur? Furthermore, is your device connected to a wired or Bluetooth accessory (headphones etc)? Unplug or disconnect them to see if your issue is fixed.
1. Lock the volume sound of your alerts. After locking, does your phone change the volume on its own? To do that, go to Settings > Sounds & Haptics > Turn off Change with Buttons. When it is set to off, does your problem occur?

You may also change the volume by dragging the slider under Ringtone up or down.
2. Restart your iPhone 18 Pro. Here is how you can restart an iPhone:
- Simultaneously press and hold the side button and either volume button until the sliders appear, then drag the Power Off slider.
3. Check this particular setting. This setting is called Attention Aware Features. Your iPhone includes a TrueDepth camera. Your iPhone’s TrueDepth camera, by using the face detection algorithm, will decide if you are looking at your device or not. When this feature is enabled, your iPhone will lower the volume of alerts if you are looking at your iPhone.
On your device, go to Settings > Face ID & Passcode and see if Attention Aware Features is enabled or not. If it is enabled, turn it off to see if your issue is fixed.
4. Update iOS. Make sure that your iPhone is running the latest version of iOS. You can update your iPhone wirelessly by going to Settings > General > Software Update. Your iPhone will check for an update. If there is an update available, click Update Now to install the update.
5. If you are still having this problem, you may want to force restart your iPhone. Here is how you can force restart an iPhone:
- Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button. When the Apple logo appears, release the side button.
If your problem still continues, then contact Apple support. You can take your device to an Apple Retail Store for inspection. You can chat with an Apple support specialist online for more information.
