EU regulation has led to Apple being forced to open up iOS in ways that many never expected, but it’s not done just yet. In an effort to ensure “effective interoperability” with other platforms, the EU wants Apple to make native features of iOS being compatible with Android, including the likes of AirDrop and more.
You have to pair first. Then you have to troubleshoot because Bluetooth isn’t very good. And then you get slow transfer rates.
With airdrop you literally open it up, find the person, then drop it. No pairing, no bullshit. It just works and you get on with your life.
