In order to get a more accurate position in the location determination, the OnePlus smartphone uses Wi-Fi and Bluetooth search as standard.

This allows apps and services to always search for Wi-Fi networks and Bluetooth devices, even if the functions are disabled.

The search via Wi-Fi  and Bluetooth can be turned on/off at any time and independently of each other.
