Can Apple 1 1 have a purple screen?

Of course. The purple screen mode should be an authorized manufacturer of Apple (such as Foxconn). After the Apple mobile phone is produced, it will enter the engineering mode through special software.

In this mode, a series of bottom initialization operations can be performed on the hard disk through the serial port on the basis that the data of the hard disk is empty, and then the card swiping or other operations can be performed.
