Almost all modern smartphones and tablets are equipped with an LED flash, which is mainly used for photography and as a flashlight. In its turn Apple company I found another, no less interesting use for it. Starting with iPhone fourth generation, the flash can function as a flasher to visually signal a call.
Is this flasher necessary?
Initially, the idea of using an LED in flickering mode was intended to help people with disabilities (hard of hearing) not to miss incoming calls and SMS notifications. But over time the situation changed. Today, many young people deliberately turn on the flashing lights, thus trying to attract the attention of others to their fashionable gadget. However, this method does not always have a positive effect. Some people may be irritated by such flickering, especially at night.
An LED flasher can help girls quickly find an iPhone in a bag among many different accessories. It's also worth noting that the flickering also applies to the alarm clock. This means that when the alarm goes off, in addition to the melody, frequent LED flashes will be visible in the room, provided that the iPhone is face down. To decide whether the flashing light is useful for you, you should turn it on for a few days on your iPhone. But keep in mind that this will drain your battery faster.
So how do you turn on flash flashing?
The procedure for turning on the LED flasher is extremely simple and can be completed in just a couple of minutes. To do this, you need to go to the “Settings” section and find the line called “Basic”. Then touch the specified line, after which a list with many sub-items will appear on the screen. 
Among them, you should find and click on the “Universal Access” item. 
Scrolling through the items in the newly opened section, you need to find and select the line called “Flash warnings”. 
After its activation, all incoming iPhone calls and messages will be accompanied by a melody with a bright optical effect.
iPhone developers under iOS control 10 additionally equipped it with another option – “Flash in silent mode”, which is also located in the “Universal Access” menu. To enable it, the user needs to perform two steps:
- by moving your finger across the screen, turn on the switch located next to the option name;
- Move the switch located at the end of the phone to the “Silent” position, in which its orange part will become visible.
After completing these steps, with each incoming call or SMS, the smartphone will vibrate and the LED will flash brightly.
Sometimes iPhone owners complain that for some reason the flashing light does not work immediately after enabling the option. In this case, you should restart the device and try to accept the call again. In this case, you need to keep in mind the following nuance. iPhone flashing periodically is only possible when its screen is turned off. If the device is not in standby mode (the screen is active), the LED will not blink.
How to disable
Disabling the LED flasher on an iPhone follows the same principle as turning it on. To turn off the flash during incoming SMS and calls, you should re-enter the “Universal Access” menu and move the switch on the screen to the inactive position.
By the way, not only owners can turn on the LED blinking function during incoming calls iPhone versions higher than iOS 5. It is also available in some other smartphones. In particular, activation of the flasher is available by default in devices MIUI firmware, and on a smartphone with Android OS you will have to install Flash application On Call.
