Why the flash blinks when you call: technical reasons
Flash Alerts was introduced in Redmi Note 7 as part of the notification system. MIUI. She's using it. LED-flashing the main camera, causing it to blink at a certain frequency when an incoming call or SMS. This option is initially designed for people with hearing impairments or for situations where the phone is in silent mode.
Technically, the blinking is realized through the interaction of several components:
- 🔦 Hardware module: LED-flash camera controlled by the power controller.
- 📱 Software layer: service com.android.server.NotificationManagerService in firmware.
- ⚙️ Settings MIUI: Menu settings Special Opportunities or Notifications.
