iPad Air 4 is the first iOS device equipped with power button fingerprint recognition. After opening the box, I found that the logic of fingerprint recognition is different from that of iPad Air 3. In addition, the light green of Qingqing Prairie is very beautiful. It is compatible with Apple Pencil 2 and Magic Keyboard, which makes this device very Pro. How about the full-screen design of the iPad Air 4? Watch the video! ,,,,,,,,,,,
