How to Block Bluetooth Access for Apps on Android & iOS

This guide shows you how to stop individual apps from using Bluetooth on both Android and iOS. You’ll learn the exact steps for each system, what happens when you block it, and how to fix common issues. No special tools or root access are needed—just your phone’s built-in settings.

What You’ll Need

An Android phone (Android 12 or newer) or an iPhone (iOS 13 or newer)
Your phone’s passcode or biometric unlock (Face ID, fingerprint) to change settings
The app you want to block already installed

Step-by-Step

Android (Android 12+ with Nearby Devices permission)

Open the Settings app on your phone.
Scroll down and tap Apps (sometimes called “Applications” or “App management”).
Tap See all apps or scroll to find the specific app you want to block. Tap on it.
Tap Permissions (or “App permissions”).
Look for Nearby devices (this is the permission that controls Bluetooth scanning and connections). Tap it.
Select Don’t allow. If you see an option for “Allow only while using the app,” you can choose that instead if you want the app to use Bluetooth only when it’s open.
Go back and exit Settings. The app will no longer be able to scan for or connect to Bluetooth devices.

iOS (iPhone and iPad)

Open the Settings app.
Scroll down and tap Privacy & Security (or “Privacy” on older iOS).
Tap Bluetooth.
You’ll see a list of apps that have requested Bluetooth access. Find the app you want to block and toggle its switch to Off (gray).
Exit Settings. The app will no longer be able to use Bluetooth.

Common Mistakes

Confusing “Location” with Bluetooth: On Android, some apps ask for location permission alongside Bluetooth. Blocking Bluetooth does not automatically block location, and vice versa. Make sure you’re changing the correct permission.
Turning off Bluetooth system-wide: This guide is about blocking individual apps, not turning off Bluetooth entirely. If you turn off Bluetooth in Quick Settings, it affects all apps and devices.
Forgetting that some apps need Bluetooth for core functions: For example, if you block Bluetooth for a fitness tracker app, it won’t sync with your watch. You may need to allow it again when you want to use that feature.
Looking for a “Bluetooth” permission on Android: On Android 12 and later, the permission is called “Nearby devices.” Older Android versions may not have a per-app Bluetooth toggle at all; you might need to use “Location” permission instead (which is less precise).

Tips

Use “Allow only while using the app” on Android: If you don’t want to fully block an app, this option lets it use Bluetooth only when you’re actively using it. This is a good balance for apps that need Bluetooth occasionally.
Review all apps’ Bluetooth access periodically: Go through the list on iOS and the permission manager on Android to see which apps have access. You might be surprised how many you don’t use.
On Android, use the permission manager: Go to Settings → Privacy → Permission manager → Nearby devices to see all apps with Bluetooth access at once. This is faster than checking each app individually.
After blocking, force-stop the app: Some apps may keep Bluetooth alive in the background until you force-stop them. On Android, you can do this in the app’s info page (Force stop button). On iOS, swipe the app away from the app switcher.

Troubleshooting

I don’t see “Nearby devices” in Android permissions. This is normal if your phone runs Android 11 or older. In that case, Bluetooth access is tied to the “Location” permission. To block Bluetooth for an app, you can deny “Location” permission, but that may affect other features. On Android 12+, the “Nearby devices” permission should appear for apps that use Bluetooth.

The app still connects to Bluetooth after I blocked it. First, restart the app (force-stop it and reopen). If it still works, check if the app has a separate in-app setting for Bluetooth that overrides the system permission. Some apps (especially older ones) may not respect the system permission correctly. If that happens, you can try clearing the app’s cache or data (on Android) or reinstalling the app.

I can’t find the Bluetooth section in iOS Privacy settings. Make sure you’re running iOS 13 or later. On older iOS, Bluetooth permissions were not available per-app. Also, if you’ve never granted Bluetooth to any app, the list might be empty—but you should still see the Bluetooth row. If you don’t, try restarting your iPhone.

Blocking Bluetooth breaks the app entirely. Some apps (like smart home controllers) require Bluetooth to function at all. If you block it, the app may crash or show errors. You can always go back and allow it again—the permission can be toggled back on at any time.

Frequently Asked Questions

Does blocking Bluetooth access also block Wi-Fi?

No. Bluetooth and Wi-Fi are separate radios. Blocking Bluetooth permission only affects Bluetooth connections. The app can still use Wi-Fi or mobile data.

Will blocking Bluetooth access save battery?

Yes, potentially. If an app was constantly scanning for Bluetooth devices in the background, blocking that permission can reduce battery drain. However, the effect is usually small unless the app was very active.

Can I block Bluetooth for system apps like Settings?

On both Android and iOS, you cannot block Bluetooth for core system apps—they are exempt for safety and functionality reasons. You can only block third-party apps.

What if I don’t see the app in the list on iOS?

If an app has never requested Bluetooth access, it won’t appear in the list. To make it appear, you may need to open the app once and try to use a Bluetooth feature (like pairing with a device). Then it will show up and you can deny it.

Does blocking Bluetooth access affect the app’s ability to use location?

On iOS, no. On Android 12+, “Nearby devices” is separate from “Location.” However, on older Android, Bluetooth scanning is tied to location, so denying location may also block Bluetooth. On newer Android, you can block Bluetooth while still allowing location.

Can I set a timer to automatically unblock Bluetooth?

No built-in feature does this. You have to manually change the permission back when you want to allow it again. Some third-party automation apps might help, but they often require extra setup and may not work reliably.
