If you are experiencing ad sound playing in the background on your iPhone, there are a few possible explanations:
- Safari Tabs: You may have left a tab open in Safari that is playing an ad. This can occur if you have opened multiple tabs and one of them is playing audio.
- Background App Refresh: Certain apps may be running in the background and playing ads without your knowledge. This can happen if you have enabled the Background App Refresh feature for those apps.
To troubleshoot this issue, you can try the following solutions:
- Close Safari Tabs: Check all open tabs in Safari and close any that are playing sound.
- Check Recently Installed Apps: Check your recently installed apps and delete any suspicious ones.
- Disable Background App Refresh: Go to Settings > General > Background App Refresh and disable the feature for apps that you don't need to run in the background.
If the problem persists, you may need to contact Apple Support for further assistance.
