Trying to receive an AirDrop transfer from someone who is not in your contacts? The iPhone automatically restricts this function to increase AirDrop privacy. AirDrop can be configured to allow transfers from everyone under Settings -> General -> AirDrop.
You should disable AirDrop if you don't use the wireless peer-to-peer file sharing feature often. Doing so will stop your phone from constantly searching for other iPhones or iPads nearby, and help you get more use out of your battery. Here's how to disable AirDrop or enable it for Contacts only:
AirDrop can be incredibly convenient for transferring images and other content between Apple devices. The feature can also be annoying. Receiving an unsolicited AirDrop request from a complete stranger can feel like an invasion of privacy. Especially if the pop-up content preview is NSFW.
To change who you accept AirDrops from on your iPhone or iPad, pull up your Control Panel by swiping up from the bottom of the screen and deep press the upper left panel to pull up more detail. Now tap on AirDrop and make your choice. The same settings can be found in Settings -> General -> AirDrop.
AirDrop is a quick and easy way to transfer files between two iOS devices. Once content is shared using AirDrop the recipient is automatically prompted with a preview of the file. There are steps involved to make sure the process is set up and ready to go.
