TL;DR
- Android 15 adds a new feature that automatically turns on Bluetooth the day after you disable it.
- The phone’s Bluetooth radio is used for several key Android features, including quick share and find devices.
- Disabling Bluetooth will slightly improve your battery, but at the cost of preventing your device from joining Google’s Find My Device network.
Google is finally launching its long-awaited “Find My Device” network in the coming days. Potentially, billions of Android devices will start pinging each other over Bluetooth, creating a lost device tracking network as large or larger than Apple’s Find My network. The way it works is that participating devices use Bluetooth to broadcast beacons that can be received by other nearby devices. The broadcast device’s location is encrypted by the receiving device and uploaded to Google’s servers, so only the owner of the broadcast device can see its location.
Because Bluetooth is an absolutely core component of Google’s Find My Device network, if a user who opts into the network disables the Bluetooth radio on their device, the Find My Device network will no longer function as intended. Disabling your device’s Bluetooth radio will not only make your device inaccessible on the Find My Device network if you lose access to your data, but it will also prevent you from helping others find their lost device. It also means that you will not be able to. Recognizing this dilemma, Google is working on a new feature in Android 15 that will essentially allow users to pause their Bluetooth radio on their device instead of disabling it.
Ann APK disassembly It helps predict features that may be added to the service in the future based on the code in progress. However, such predicted features may not be publicly released.
In recent preview builds of Android 15, we found numerous mentions of the “Bluetooth Auto-On” feature. This feature, as its name suggests, can automatically turn on your Bluetooth radio. When this feature is enabled, a toggle that says “Automatically turn back on tomorrow” appears when users try to turn off Bluetooth from the quick settings dialog introduced in the recent Android 14 QPR2 update. There may be cases. This toggle may be accompanied by text informing users that “features such as Quick Share, Find My Device, and Device Location use Bluetooth.”
<string name="turn_on_bluetooth_auto_info">Features like Quick Share, Find My Device, and device location use Bluetooth</string>
<string name="turn_on_bluetooth_auto_tomorrow">Automatically turn on again tomorrow</string>
Similar toggles and text may be found on the Bluetooth settings page (Settings > Connected devices > Connection settings > Bluetooth) and Bluetooth scan (Settings > Location > Location Services > Bluetooth Scan).
<string name="bluetooth_empty_list_bluetooth_off_auto_on_available">When Bluetooth is on, your device can communicate with other nearby Bluetooth devices. Features like Quick Share, Find My Device, and device location use Bluetooth.</string>
<string name="bluetooth_scanning_on_info_message_auto_on_available">"When Bluetooth is on, your device can communicate with other nearby Bluetooth devices. Features like Quick Share, Find My Device, and device location use Bluetooth.
Apps and services can scan for nearby devices at any time, even if Bluetooth is turned off. This can be used, for example, to improve location-based features and services. This can be changed in the Bluetooth scan settings. “

The code for the Bluetooth auto-on feature has already been handed over to AOSP, and a little more information about it has been revealed. First, only system apps can enable this, so third-party apps can’t switch your device’s Bluetooth radio without your knowledge. Second, the API is not restricted to Android 15, so it may be available on earlier versions of Android as well. However, the device must use his AOSP’s Bluetooth stack instead of the custom stack. Still, a comment in the code states that the Bluetooth auto-on feature is not supported on all devices.
I’m not sure why the auto-on feature doesn’t work on all devices when the OS already allows you to manually toggle Bluetooth, but that may be why I didn’t see the auto-on toggle when I enabled the feature. not. The Bluetooth auto-on feature is not included in either Android 15 Developer Preview 2 or Android 14 QPR3 Beta 2.1, but may be included in a future Android 15 beta release. I’ll keep an eye on it to see if it lands.
