How to make a light signal on an iPhone. How to turn on flash when receiving a call or SMS on iPhone
Because Since the iPhone does not have a separate notification indicator, as is implemented by other smartphone manufacturers, Apple developers suggested using the built-in LED flash for these purposes.
Starting from the 4th generation, the flash on a smartphone can be used not only in flashlight mode or photo/video shooting. It also serves as an additional alert signal for incoming calls, SMS messages, etc.
It is worth noting that enabling this option will result in increased battery drain. But if you use the flash instead of vibration and melody, and not all together, then the battery, on the contrary, will last longer.
Initially, this option was planned to help people with hearing impairment. But LED notifications can also come in handy if you're in a noisy room and your phone is on the table. In this case, vibration will not help, but you will easily notice the blinking flash on your iPhone.
Settings to turn on flashing flash on iPhone
To set the flash, follow the steps:
1 Go to the “Settings” menu.
2 Next “Basic” item.
3 Next “Universal Access” item.
4 Next “Flash warnings” item.
5 Activate the slider.
After turning on the flash, be sure to place your iPhone face down, otherwise you won't see anything.
Video instruction
Until the 4th generation of iPhone, there was no LED flash on Apple devices; those who wished had the opportunity to purchase it as a separate accessory. It even had its own name – iFlash.
Then the creators decided that it was impractical, so it migrated directly to the smartphone. Let's find out how to turn on the flash on iPhone 4.
Why and how to turn on the flash?
Nowadays, most smartphones have a flash; its main task is to improve lighting when taking photographs, but it can also be used for other purposes. One of these tasks is notifying the user about a call. If you work in a noisy environment where hearing a ringtone would be difficult, flickering will indicate that someone is trying to contact you.
The flash turns on in several steps.
- We go to the settings section, select the main ones there
- In this menu, the “universal access” item is important to us.
- In the next step, activate the LED flash for warnings.
That's all, now the flash on the device will start blinking when making calls. She reacts not only to them, but also to incoming messages. If you set an alarm clock and place your smartphone close to you, you may be woken up by the flickering LED. There is an interesting point - it will only start flickering if the smartphone is switched to lock mode. In the active state, the LED signal will not light up.
Please note that using a flash for these purposes will negatively affect the battery life of the phone. If, after activating the function, it turns out that the smartphone began to work less than before, then you should not be surprised.
General information about using the flash
If you intend to use this part of the device in a more familiar style, then first learn how to switch your smartphone's cameras. All modern gadgets have two of them, the front one is for selfies. The iPhone is equipped with good cameras that allow you to take high-quality pictures even in low light conditions, but the flash is designed specifically to improve the perception of the device. To activate it, in shooting mode, find the lightning icon located in the upper corner of the screen.
There are several types of flash uses. If it is set to “Off”, then it does not work at all, “Auto” indicates action in automatic mode, when the device adapts to lighting conditions, and the LED will light up only if it is dark enough nearby. “On” forces the LED to work in forced mode, it is activated with every photo.
This is a useful thing, and if you download a utility from the app store that turns an LED into a flashlight, you can use your smartphone to illuminate the surrounding area. We hope that the setup will not cause any difficulties.
