Where can I turn off the apple when it flashes for 5S?

This function is called led flashing reminder, which can be turned off when there is a text message or an incoming call. The method is as follows:

1. First open the "Settings" of Apple's mobile phone, then click "General", and find and click "Accessibility" in the general options. (as shown in the figure below)

2. In the auxiliary function, find "LED flashing to remind you", and then turn off the switch on the right. After the setting is completed, the flash of Apple's mobile phone will be successfully turned off. (as shown in the figure below)
