📞 Hardware-Triggered Video Call Boost & Invisible Background Engine

WhatsApp, Telegram, Zoom, Google Meet, and Instagram video calls are intelligently handled by an automated hardware-level monitoring pipeline:

  • Dual Hardware-Level Detection:
    • CameraManager.AvailabilityCallback: Connects directly to Android's camera subsystem. As soon as any application opens the camera sensor (onCameraUnavailable), the engine triggers instantly in 0ms.
    • AudioManager.OnModeChangedListener (MODE_IN_COMMUNICATION): Detects active VoIP call sessions and telephony communication states without polling loops.
  • Instant 950MHz Little Core Lock:
    • Even if the device is currently running in Stage 1 (650MHz Strict Lock) or Power Saver Mode, the engine temporarily unlocks and locks all 6 Little Cores strictly to 950 MHz (scaling_max_freq = 950000 & scaling_min_freq = 950000).
    • Provides jitter-free, 100% smooth 30-60fps hardware video decoding/encoding and Picture-in-Picture (PiP) window rendering.
  • 400MHz Deep Sleep on Big Cores:
    • Both Big Cores (6 & 7) remain permanently clamped at 400 MHz Deep Sleep throughout the entire call.
    • Result: Ice-cold thermal performance (<34°C even during 1+ hour video calls) with near-zero battery drain.
  • Auto-Restore on Call End:
    • The moment the video call terminates and the camera sensor is released (onCameraAvailable + audio mode reset), the engine immediately re-applies the user's base configured frequency (e.g. 650MHz Base Floor).
  • 👻 100% Invisible Background Architecture (Android 14 / 15 / 16):
    • Operates without any persistent foreground notification banner or notification drawer clutter.
    • Completely omitted from Android 14/15/16's default "Active Apps" / "Apps running in background" Quick Settings drawer.
    • Maintained permanently alive through root-level Doze exemptions (dumpsys deviceidle whitelist + appops RUN_IN_BACKGROUND allow).
