RKpx3 Android Update: Enhancing Performance and Quality

1. Download Kernel Adiutor (available on F-Droid or GitHub).
2. Go to CPU → Governor → Set to performance (for gaming) or schedutil (for daily). Warning: Performance keeps all cores at max speed. Use a fan.
3. Go to GPU → Maximum frequency → Set to 800MHz (if your RK3399/PX3 allows it; default is 650MHz).
4. Go to I/O Scheduler → Internal Storage → Set zen or fiops. Read-ahead → Set to 2048 kB.

• 720p display (not 1080p)
• 44.1kHz/16-bit audio max
• H.264 8-bit, not 10-bit or HEVC

• Improved dynamic range handling and HDR passthrough on compatible displays.
• Reduced banding and better tone-mapping for gradients.

Cause:

You flashed an image for a different RK PX3 variant (e.g., RTL8723BS vs. AP6255 chip). Fix: Extract the parameter.txt from your stock backup. Flash only the resource.img and boot.img from the custom ROM, keeping your stock vendor partition.
