Apple's 6plusLED flash was turned off when the phone was making a call, and it will be turned on two days ago. Yesterday, I found that it wouldn't turn on, and the switch showed on?

First, please open the "Settings" application on the main screen of Apple's mobile phone.

Find the General column in the list of settings, and then click Open.

Then find the column of "Accessibility" in the general list and click Enter. four

Then, please find the option of "LED flashing as a reminder" under hearing in the accessibility list, and click Open.

Next, you can call yourself or send a short message to check whether the LED on the back of the phone will flash.

Of course, if you have a lot of phone calls and text messages, when you turn on the LED flashing prompt, it will definitely consume the battery power of your mobile phone.
