DFG Controller — Universal Android Kernel Manager & Kernel Controller App (Root)

DFG Controller is a free, open-source Android kernel manager / kernel controller app for rooted phones and tablets. Tune CPU governors, CPU frequencies, GPU, I/O scheduler, TCP congestion (BBR/Cubic), KCAL display colors, DPI/resolution, zRAM, wakelocks, thermal limits, gaming mode, and app-triggered bypass charging — from one modern Material 3 UI.

Looking for a Franco Kernel Manager alternative, EX Kernel Manager alternative, SmartPack Kernel Manager alternative, or Kernel Adiutor / Kernel Adiutor-Mod alternative? DFG Controller is exactly that: a universal kernel tuner, kernel tweaker, CPU governor changer, I/O scheduler changer, and sysfs editor that works on any rooted kernel — not just one device. Born and optimized for the DaisyForGaming (DFG) kernel on Xiaomi Mi A2 Lite (daisy), now universal (v2.3.0+).

Highlights — v2.3.0 Universal Kernel Control

• Universal kernel support: works on any rooted Android kernel — DFG /sys/devices/platform/dfg/ nodes are a fast-path; standard Linux sysfs nodes (cpufreq, block, net, power_supply) are used everywhere else.
• Cyberpunk UI Engine: Fully customizable accent colors (Cyan, Red, Green, Purple, Orange, Pink) with neon glow effects.
• Version-Aware Updates: Automatic detection of running Android SDK for matching kernel ZIP variants.
• Thermal Safety: Intelligent monitoring and auto-reversion of aggressive profiles during overheat.
• Premium Splash Animation: Futuristic launcher sequence with logo and animated app name.
• Deep Shell Integration: Rebuilt ShellManager on libsu with better error handling, fallback support, and SELinux permissive auto-tuning.
• Enhanced Diagnostics: Real-time kernel capability probing (UNIVERSAL / DFG UNIFIED mode) with per-feature support reporting.

Unified Sysfs API Reference

The app prioritizes the following nodes:

• dfg/profile: Performance / Balanced / Battery (write lowercase name)
• dfg/cpu_governor: System-wide CPU governor
• dfg/io_scheduler: Block device I/O scheduler
• dfg/tcp_congestion: TCP congestion algorithm
• dfg/dyn_fsync: Dynamic FSync toggle (0/1)
• dfg/gaming_charge: Gaming charge toggle (0/1)

Key Features

• Intelligent Profiles: One-tap apply for Performance, Balanced, and Battery presets.
• Custom Tunables: Precise control over CPU, I/O, TCP, and kernel features.
• Thermal Safety: Automatic blocking of unsafe overrides if the device overheats (>60°C).
• Kernel Logs: Built-in dmesg viewer with live tailing.
• Profile Widget: Toggle and monitor your kernel state directly from the home screen.
• Boot Persistence: Automatically reapplies your chosen profile on every reboot.

Installation & Root

1. Grant Root: The app requires Magisk / KernelSU / APatch for full functionality.
2. Any kernel works: Optimized for the DaisyForGaming (DFG) kernel on Mi A2 Lite (daisy), but every feature your kernel exposes via standard sysfs works on any rooted device.
3. SELinux: The app attempts to set SELinux to Permissive only if unified nodes are inaccessible.

Build Instructions

1. Open in Android Studio (Ladybug or newer).
2. Sync Gradle.
3. Run ./gradlew assembleRelease for the optimized premium build.

FAQ (Short)

• Is root required? Yes — kernel parameters live in sysfs and need superuser access.
• Which Android versions? Android 8.0 (SDK 26) and newer.
• Do I need the DFG kernel? No. DFG enables a fast-path; standard kernels use standard sysfs nodes automatically.
• Does it collect data? No telemetry. Settings stay on-device (DataStore); update checks hit a static GitHub JSON.
• How do I revert? Turn off Gaming Mode, reset Display settings, or simply reboot — sysfs resets on reboot.
