The role of mobile phone breathing light

Breathing light mainly plays the role of reminder, which can make the mobile phone no longer a cold "brick" and add a touch of embellishment to it. When there is a missed call, information or even charging in the mobile phone, it will blink rhythmically from dark to bright and from bright to dark, which feels like a light breath, thus playing the role of notification and reminder.

As a weak warning, breathing light's reminder is more significant than the warning, and it will not let us miss the important news, nor is it as strong as the strong warning, which brings people trouble. Support a variety of colors, you can set different flashing colors according to different information notifications, such as green for missed calls, red for low battery, yellow for unread SMS reminders, etc. Some mobile phones also support custom colors.
