What is nearby device scanning?

Nearby device scanning is a feature found on many mobile devices that allows users to discover and connect to nearby devices using various wireless technologies, such as Bluetooth, Wi-Fi Direct, and NFC. With this feature, users can share files, play games, and even stream media with other users in close proximity.

Some devices with nearby device scanning may also have the ability to scan for beacons, which are small broadcasting devices that use Bluetooth low energy technology to transmit signals that can trigger actions or display information on nearby devices.

It is important to note that nearby device scanning can pose a security risk if not used responsibly. For example, attackers could exploit vulnerabilities in the scanning process to gain access to sensitive data or take control of a device. It is recommended that users only connect to trusted devices and secure their own devices through password protection and other security measures.
