Bluetooth allows users to connect wireless headphones, earphones, or speakers to their mobile phones, enabling them to listen to music, watch videos, or make calls without the need for wired connections.

2. Hands-free calling:

Bluetooth connectivity enables users to connect their mobile phones to hands-free car kits or Bluetooth-enabled headsets, allowing them to make and receive calls while keeping their hands on the steering wheel or performing other tasks.

5. Internet tethering:

Bluetooth can be used to share the internet connection of a mobile phone with other devices, such as laptops or tablets, by creating a personal hotspot. This allows users to access the internet on their other devices when a Wi-Fi network is not available.

6. Smart home integration:

Bluetooth connectivity allows mobile phones to connect and control various smart home devices, such as smart lights, thermostats, or security systems, providing users with convenient control over their home automation systems.
