To enable bluetooth on Samsung phones under control Android, swipe down from the top of the screen, a quick access menu will appear. Just click on the bluetooth icon and it will activate. Please note that an icon will appear at the top of the screen (next to the time) – this means that the bluetooth is on.
Alternatively, use the following: go to Settings – Connections – Bluetooth. Additional bluetooth settings are also available here.
After turning on the bluetooth, the phone will automatically search for available devices nearby (within 50 meters, depending on the presence of obstacles – walls or other objects). Make sure that the device you are looking for is visible to other phones (more on that later).
