• Disabled surfaceflinger composition bypass for consistent UI frame rates
• Forced SkiaGL rendering pipeline for smoother 2D application drawing
• Increased background process limits to allow better multi-tasking
• Adjusted LMKD (Low Memory Killer) parameters specifically for 4GB/6GB RAM
• Assigned maximum priority (renice) to foreground applications and launcher
• Disabled background cpuset throttling to prevent audio stutters under heavy load
• Lowered vfs_cache_pressure to 50 to keep filesystem structures in memory longer
• Increased I/O readahead values to 2048kb for faster app loading from storage
• Switched I/O scheduler to deadline for better eMMC flash memory performance
• Disabled software CRC checks in the MMC driver to boost read/write speeds
• Implemented fast garbage collection parameters in the Dalvik VM

Memory Management (RAM & Dalvik)

• Switched to LZ4 compressed ZRAM for high-speed memory swapping
• Set Swappiness to 60 for an optimal balance between RAM and ZRAM usage
• Increased dirty_ratio and dirty_background_ratio to reduce I/O bottlenecks
• Tweaked min_free_kbytes to prevent the system from aggressively killing apps
• Adjusted Dalvik VM heap sizes (heapstartsize, heapgrowthlimit, heapsize) for Ginkgo
• Rewrote dalvik-cache generation to pre-optimize system apps on first boot
• Cleaned up unnecessary background services to free up approximately 400MB of RAM

Battery Life & Deep Sleep Optimization

• Optimized deep sleep state transitions for minimal idle battery drain
• Fixed suspend_backoff wakelocks that kept the device awake during screen-off
• Aggressively tuned Doze mode to kick in much faster after screen timeout
• Reconfigured AlarmManager to batch background syncs and reduce CPU wakeups
• Disabled logd and removed all system debugging traces to stop background CPU usage
• Reduced the frequency of dumpstate generation and tombstone logging
