The chip on the back of the Real Me GT Neo5 phone is made up of LED lights that can be set to control their glow. You can follow these steps to set up:
Open the phone Settings, enter the \"Display and brightness\" option;
In the \"Display and Brightness\" page, find the \"Back indicator\" option;
Click the \"Back indicator\" option to enter the Settings page;
In the Settings page, you can choose to turn the back indicator on or off, and you can also set its color and blink mode.
After you turn on the back indicator, when you receive a new message or notification, the chip on the back will send out the corresponding color and flash mode to remind you. It should be noted that not all phone models support the back indicator function, depending on your phone model.
