Bluetooth icon does not appear on ios 12
ı installed ios 12 my iphone 6s plus. But while bluetooth is opened , bluetoot ikon does not eppear
That's correct. If you go out to the iOS12 User Guide, the Bluetooth Symbol has been removed from the listing of available symbols on iPhone. This was clearly done on purpose and further demonstrates Apple's position that there really is no valid reason to turn Bluetooth off. When not connected to a BT enabled device, BT uses virtually no power and because of the way Apple encodes the BT radio, there are no security issues one can experience.
