Bluetooth uses a radio frequency to share data over a short distance. It’s baked into just about every smartphone you can buy nowadays. But, as with any connection, it has its vulnerabilities.
My advice: Turn off Bluetooth when not using it. Keeping it active all the time makes your device more vulnerable. Plus, you’ll get more battery life.
- On iPhone, go to Settings > Bluetooth and switch it off.
- On Android, go to Settings > Connected Devices > Connection Preferences > Bluetooth and switch it off. (Note: Steps vary based on your phone model.)
⚠️ You’d be surprised what someone can do if they break into your phone via Bluetooth.
