A fitness app that suddenly asks to use Bluetooth, or a game that seems to search for nearby devices for no clear reason, can make anyone pause. If you have ever wondered how to check and change which apps can use your iPhone or Android Bluetooth, the good news is that both operating systems keep this setting in one organized place, separate from the main Bluetooth on/off switch. This article walks through exactly where to find that list on iPhone and Android, how to turn access on or off for individual apps, and what to do when an app cannot connect to an accessory after you have made a change.
The short answer: on iPhone, app-level Bluetooth permissions live under Privacy & Security in Settings. On Android, the same kind of control is usually called Nearby devices and sits inside each app’s permission settings, though the exact wording and menu path can vary by phone maker and software version.
Below, you will find step-by-step instructions for both platforms, a comparison of how the two systems differ, troubleshooting tips for when an app cannot find an accessory, and a few cautions worth knowing before you start switching permissions off.

What to Check First Before Changing Any Permission
Before diving into any settings menu, it helps to understand what this permission actually controls. App-level Bluetooth access decides whether a specific app is allowed to search for, connect to, or communicate with nearby Bluetooth devices, such as headphones, fitness trackers, smart scales, or car systems. This is different from the phone’s overall Bluetooth switch, which turns the entire radio on or off for the device. You can have Bluetooth turned on for your phone as a whole, but still block one particular app from using it.
It is worth taking a moment to think about which apps genuinely need this kind of access. An app that pairs with a wearable or a wireless speaker clearly needs it. A social media app or a game that requests the same permission may be using it for a feature you are not aware of, such as finding nearby users or devices for local multiplayer. Neither situation is inherently alarming, but knowing which apps have asked for access gives you a clearer picture of what is happening on your phone.
Apple notes that the list shown under its Bluetooth privacy settings only includes apps that have actually requested this kind of access. If an app is not listed, it likely has not asked for Bluetooth permission at all, so there is nothing to toggle for that app. The same general idea applies on Android: permissions only appear for apps that have requested them during use or installation.
Keep in mind that turning a permission off does not uninstall the app or erase its other settings. It only removes that one specific capability. This makes it a low-risk way to experiment, since you can always turn the permission back on later if an app’s feature stops working the way you expect.
💡 Key point: App-level Bluetooth permission and the phone’s main Bluetooth switch are two separate controls, and only apps that have requested access will appear in these lists.
How to Check and Change Bluetooth Access on iPhone
On iPhone, Apple centralizes hardware-related permissions, including Bluetooth, inside the Privacy & Security section of Settings. This is the same general area where you would find camera, microphone, and location permissions, so if you have adjusted any of those before, the layout will feel familiar.
- Open Settings.
- Tap Privacy & Security.
- Tap Bluetooth.
- Turn access on or off for each listed app.
Each app in this list will show a simple switch. Turning it off means that app can no longer use Bluetooth to scan for or connect to nearby accessories, even though your phone’s Bluetooth radio itself stays on for everything else. Turning it back on restores that app’s ability to request Bluetooth connections the next time you open it.
If you cannot find a specific app in this list, it most likely has not requested Bluetooth access, so there is no toggle to adjust. In that case, opening the app itself and triggering the feature that needs Bluetooth, such as trying to pair a device from within the app, may prompt iOS to ask for permission, after which the app should appear in the Bluetooth settings list going forward.
Apple’s support documentation also covers this under its broader guide to controlling access to hardware features on iPhone, which includes similar steps for camera, microphone, and other sensors. If you ever run into unexpected behavior, such as an app repeatedly asking for Bluetooth permission even after you have granted it, checking Apple’s official support page for your specific iOS version is a reliable way to confirm the exact current wording and layout, since Apple does update these screens from time to time.
💡 Key point: On iPhone, every Bluetooth permission for every app lives in one list under Privacy & Security, making it easy to review everything at once.
How to Check and Change Bluetooth Access on Android
Android handles this permission a bit differently, partly because Android phones come from many different manufacturers, each of which can customize the Settings app’s look and menu names. The core idea is the same as iPhone, but you may need to search a little to find the exact screen on your device.
To check or change Bluetooth-related permission for a single app, follow this general flow:
- Open Settings.
- Tap Apps, then select the app. If needed, tap See all apps.
- Tap Permissions.
- Tap Nearby devices or, on some phones or older versions, Bluetooth.
- Choose Allow or Don’t allow.
If you would rather see every app that has access to this permission at once, rather than checking one app at a time, many Android phones offer a permission-based view instead:
- Open Settings.
- Tap Security & privacy (or Security & Privacy) then Privacy then Permission manager.
- Tap Nearby devices and select an app to change its permission.
This second path is often more convenient if you want a full picture of which apps can access nearby devices, similar to how the iPhone Bluetooth list works. However, not every Android phone offers a Permission manager under this exact name, so if these steps do not match what you see, try typing Permissions, Nearby devices, or the name of the app directly into the search bar at the top of the Settings app. Searching is often the fastest way to find a renamed menu, since manufacturers like Samsung, Google, and others sometimes use slightly different labels or add extra steps.
Android 12 and later versions generally use the Nearby devices permission to cover most Bluetooth-related actions an app might request. On older versions of Android, some Bluetooth features were tied to the Location permission instead, which can be confusing if you are used to newer phones. If you are troubleshooting an older device and cannot find a Bluetooth or Nearby devices toggle, checking the Location permission for that same app is worth trying.
💡 Key point: Android offers two ways to manage this permission, by app or by permission type, and the exact menu names can vary by phone maker and Android version.
iPhone vs. Android: Key Differences
While both platforms let you control which apps can use Bluetooth, the structure and terminology differ enough that it helps to see them side by side, especially if you use both an iPhone and an Android device, or if you are helping a family member switch between the two.
| Aspect | iPhone | Android |
|---|---|---|
| Main menu path | Settings > Privacy & Security > Bluetooth | Settings > Apps > [app] > Permissions, or Settings > Security & Privacy > Permission manager |
| Permission name | Bluetooth | Nearby devices (Android 12 and later); Bluetooth on some older versions |
| View by app or by permission | By app only, all in one Bluetooth list | Both options available on many phones |
| Consistency across devices | Consistent across iPhone models and iOS versions | Can vary by manufacturer and Android version |
| Related permission | Not typically tied to Location | Older versions may also involve Location permission |
One of the clearest differences is consistency. Because Apple controls both the hardware and software for iPhone, the Bluetooth privacy screen tends to look and behave the same way across most recent iOS versions. Android, on the other hand, is used by many different phone makers, including Samsung, Google, and others, each of which can adjust the Settings app’s appearance. This is why the research notes describe the Android steps as general guidance rather than an exact match for every single phone.
Another difference worth noting is how each platform organizes the information. iPhone’s Bluetooth settings page shows every app that has requested access in a single, scrollable list, which makes a full review relatively quick. Android’s Permission manager offers a similar by-permission view, but it is not available in the exact same form on every device, so some users will only have the by-app method available to them.
Despite these differences, the underlying goal is the same on both platforms: give you a clear way to see which apps can use Bluetooth and let you turn that access off for any app that does not need it. Once you understand the general flow, open the app, find its permissions, locate the Bluetooth or Nearby devices entry, switching between an iPhone and an Android device becomes much less confusing.
Useful Ways to Use These Settings
Beyond simply knowing where these settings live, there are a few practical ways to put this knowledge to use. One is doing a periodic review of every app that has Bluetooth access, especially after installing several new apps over a few months. Since both iPhone and Android show a list of apps that have requested this permission, scanning through that list occasionally can reveal apps you forgot were using Bluetooth at all.
Another practical use is troubleshooting connection problems with a specific accessory. If a wireless headset, smartwatch, or fitness tracker is not showing up inside a particular app, checking that app’s Bluetooth or Nearby devices permission first can save time before assuming the accessory itself is broken. This is often a faster first step than restarting the phone or the accessory.
These settings are also useful when lending a phone to someone else temporarily, or when handing down an old phone to a family member. Reviewing which apps have Bluetooth access, and turning off permissions for apps that are no longer needed, is a reasonable part of general housekeeping before passing a device along, though it is not a substitute for a full factory reset if you are giving the phone away permanently.
Finally, some people find it useful to turn off Bluetooth access for apps they rarely use but keep installed, simply to reduce the number of apps actively able to scan for devices. This does not change performance in any guaranteed way, but it can make the permission list easier to scan and understand at a glance.
If an App Still Cannot Find a Device
If an app cannot locate or connect to a Bluetooth accessory even after you have confirmed its permission is turned on, there are a few more things worth checking before assuming something is broken. Start with the basics: confirm that the phone’s main Bluetooth switch is turned on, not just the app’s individual permission. An app can have full Bluetooth permission and still fail to connect if the phone’s Bluetooth radio itself is switched off.
Next, confirm that the accessory is actually available for connection. Many Bluetooth devices need to be put into a specific pairing mode, often by holding down a button, before they are visible to a phone. If the accessory is already paired with another device, such as a different phone or a tablet, it may not show up until it is disconnected from that other device first.
On older Android phones, remember that some Bluetooth-related features were historically tied to the Location permission rather than Nearby devices. If an app seems to have Bluetooth or Nearby devices permission already granted but still cannot find anything, checking whether that same app also needs Location permission is a reasonable next step, particularly on phones running older versions of Android.
- Confirm the phone’s main Bluetooth switch is on.
- Confirm the app’s Bluetooth or Nearby devices permission is set to Allow.
- Confirm the accessory is in pairing mode and not already connected elsewhere.
- On older Android phones, check whether Location permission is also required.
- Restart the app, and if needed, restart the phone.
If none of these steps resolve the issue, the app’s own support page or the phone maker’s support instructions are the most reliable next resource, since accessory pairing issues can sometimes be specific to a particular app version or phone model.
💡 Key point: Before assuming an accessory is broken, confirm the phone’s main Bluetooth switch, the app’s specific permission, and whether the accessory is in pairing mode.
Things to Watch Out For
Turning off an app’s Bluetooth permission is a reversible, low-risk change, but a few details are worth keeping in mind. First, turning off this permission for one app does not turn off Bluetooth for the entire phone, and it does not necessarily remove any accessories that are already paired with your phone at the system level. Those pairings are managed separately from individual app permissions.
Second, some apps rely on Bluetooth access specifically to find or communicate with nearby accessories as a core part of their function. Denying access to these apps may stop certain features from working entirely, not just limit them. Before turning off permission for an app you actively use with a Bluetooth accessory, consider whether that feature is one you rely on regularly.
Third, if an app or a specific permission type is not showing up where you expect it, there are two likely explanations: either the app has never actually requested that permission, so there is nothing to display, or your phone’s software uses a different permission name or menu structure than described here. In either case, checking the app’s own in-app settings, or searching your phone maker’s official support instructions, is the most direct way to confirm what is happening on your specific device.
Because these settings touch on privacy and how apps interact with nearby devices, it is a good idea to check the service’s official help page or contact its support team if you need exact details for your specific phone model or app version, since menu names and steps can shift with updates on both platforms.
Frequently Asked Questions
Q. Does turning off Bluetooth permission for an app also disconnect paired devices?
Not necessarily. Turning off an app’s Bluetooth permission limits that specific app’s ability to use Bluetooth, but it does not automatically remove or disconnect devices already paired with your phone at the system level.
Q. Will I lose app features if I turn off its Bluetooth access?
Possibly, if the app depends on Bluetooth to find or communicate with nearby accessories. Some apps may show reduced functionality or stop working as expected for Bluetooth-related features once access is denied.
Q. Why does an app ask for Location permission for a Bluetooth feature?
On older versions of Android, some Bluetooth scanning features were tied to the Location permission rather than a separate Bluetooth or Nearby devices permission. Android 12 and later generally use Nearby devices instead, though this can still vary by app.
Q. What if an app is not listed under Bluetooth permissions at all?
According to Apple, an app only appears in the Bluetooth privacy list if it has actually requested Bluetooth access. If an app is not listed, it most likely has not asked for that permission, so there is nothing to toggle for it yet.
Q. Can I review every app’s Bluetooth access in one place on Android?
On many Android phones, yes, through the Permission manager under Security & Privacy, where you can tap Nearby devices to see every app with that permission. However, this exact menu is not guaranteed to be available on every phone model or Android version.
Q. Is checking app permissions the same as turning off Bluetooth entirely?
No. App-level Bluetooth permissions control individual apps, while the phone’s main Bluetooth switch, found separately in Settings, controls whether the Bluetooth radio is on or off for the entire device.
Q. Why do Android menu names differ from what is described here?
Android phones come from many manufacturers, each of which can adjust the Settings app’s layout and wording. If the steps here do not match your phone exactly, searching Settings for Permissions, Nearby devices, or the app’s name is a reliable way to find the equivalent screen.
