Apple mobile phone supports pencil handwriting.

Apple phones don't support pencil handwriting. ApplePencil is different from ordinary capacitance pen. It doesn't work entirely by capacitance. The pen tip of ApplePencil will emit electromagnetic waves in a certain band. The touch chip that can receive signals in a specific model of iPad is specially customized. When the ApplePencil touches the iPad screen, the chip can receive the special frequency band emitted by the ApplePencil. If you have a spectrum probe in your hand, you can use it to scan this frequency band. However, the chip that can receive special touch signals is not installed on the iPhone, and the iPhone does not support the use of ApplePencil.
