Android phone number discoloration

Does the subject want to be hypocritical? "Why the Android phone number changes color"? Mark the number and set up the mobile phone system.

1, the number is marked: if the mobile phone number is marked as a suspicious number such as sales phone, harassing phone or spam message, it will be displayed in different colors. This situation is caused by a large number of numbers reported by users or numbers detected by security software.

2. Mobile phone system settings: Some mobile phone systems will change the color of mobile phone numbers according to different usage scenarios or purposes. For example, during a call, when incoming or outgoing calls are displayed, these numbers will be highlighted in different colors so that users can quickly identify them.
