How to turn flight mode on and off on my Samsung smartphone

Note:

With flight mode, the phone's wireless signals are turned off (mobile network, Wi-Fi, Bluetooth). This allows you to use the other features of your phone safely during flights and in other areas where radio transmitters arenʼt allowed.

Applicable to: Samsung Galaxy S series (S7 and higher), A series (A5 and higher), Note series (Note9 and higher), Xcover4, J3, Z Flip series, Fold series.
