What is data sharing on Android and what is it for?
The function of share data —also known as tethering, access point, or hotspot—allows your Android device to function as a portable router, transmitting its mobile data connection to other devices wirelessly or via cable. This is especially useful when there's no Wi-Fi network nearby or you prefer to avoid public networks for privacy and security reasons. You can connect other phones, tablets, laptops, smart TVs, or any device that supports data transmission via Wi-Fi, Bluetooth, or USB.

- Connect your laptop while traveling or away from home without Wi-Fi available.
- Help a friend who has run out of mobile data.
- Use mobile connection in areas where the fixed network is limited or unstable.
- Avoid security risks associated with public or open networks.
