If you want to know the notifications that have reached the iPhone, if you lock, the notification dialog displayed on the automatically lit iPhone will be an orthodox means.Depending on the settings, it will notify you with a notification sound or vibration, so you will notice even if you put your iPhone in your pocket or back.
However, the situation changes as the distance to the iPhone is expanded.Notification sounds and vibrations are noticed if the iPhone is in the immediate side (in close contact), but it will not be so if you are a few meters away.For example, if you put an iPhone on your desk in a situation where you tend to leave a little noisy, such as an office, you will not notice it.
"LED flash" is effective to avoid such a situation.When the notification arrives, it usually flashes the LED light on the back of the main unit used as a camera flash or flashlight.It shines shiningly with a lot of brightness, so you notice even if you are away.Like a chest pocket or a tote bag, you can notice it while moving if it is a non -sealed space.
Since this LED flash is positioned as a type of iOS accessibility function (support function for the person with disabilities), the "Settings" application "Accessibility" item has a switch on/off.The initial value is set off, so let's turn it on according to the following steps.
If you put the iPhone on the display on the display, you will not be able to notice the LED flash because the light does not spread.When placing an iPhone, be sure to learn the habit of hiding.
