What about Apple's mobile phone? Is it lit before the message that has arrived or not been read?

Apple's mobile phone turns on the LED to flash as a reminder, and the information that has come or not will light up in front. The specific operation steps are as follows:

1. First, find the "Settings" option on the phone desktop.

2. Click and locate the General tab.

3. Then find the Accessibility tab and click Enter. After entering the auxiliary function tab, the LED flashing reminder is found in the drop-down box.

4. Then click the "LED flashing reminder" button to turn on the information flashing.
