3. CHANGELOG DETAILS 

(05/09/2026 Update): 

- EvolutionX 12.1 Core: Synced with the latest upstream EvolutionX source tree. 

- AutoLock Mode (Media Sleep Guard): 

 * Purpose: Solves the issue of devices staying awake indefinitely when watching videos or listening to media in bed (e.g., YouTube, TikTok, Twitch, audiobooks). 

 * Wake Lock Override: Forces the screen to turn off and locks the device according to a designated timer, ignoring apps that keep the display awake. 

 * Trigger Conditions: 

  - Mode A: Always Active — locks the device strictly after the configured timer. 

  - Mode B: Wake Lock Detection Only — activates only when an app is actively holding a wake lock or preventing standard system sleep. 

 * Media Auto-Pause: Optional toggle to forcefully pause media playback (including background audio) when the sleep timer runs out. 

 * Timer Flexibility: Configurable from 10 seconds up to 60 minutes. 

 * Interactive Live Notification: Displays an ongoing countdown timer in the notification shade. 

 * Smart Reset: Automatically cancels and resets the countdown whenever user activity is detected (touch inputs, volume button clicks, or connected peripheral inputs). 

- Google Now Playing: Resolved ambient music recognition issues; Now Playing is now fully functional. 

(30/08/2026 Initial A17 Release Recap):

- Auto-HBM Re-architecture: Completely rewritten for reliable light sensor reading and smooth transitions. HBM can now lock the manual brightness slider while active to avoid calibration conflicts. 

- Silent Animation & Shape Packages: Custom overlay packages now install fully silently without requiring manual user confirmations or triggering Google Play Protect warnings. 

- Isolated DT2W (Double Tap to Wake): Re-engineered as a dedicated process inside SystemUI, directly intercepting low-power touch events rather than piggybacking on stock hooks. 

- Screen Rotation Engine: Added customizable screen rotation animations with built-in templates and a live trajectory editor. 

- Pixel Launcher Hook Improvements: 

 * Resolved system crashes when removing Live Tiles from the Recents carousel. 

 * Removed duplicate Google Feed toggles and top-widget options from external hooks (both are natively managed via internal launcher settings). 

4. PIXELEXTRAPARTS (PEP) EXCLUSIVE FEATURES 

PixelExtraParts is a privileged system engine developed specifically for Pixel devices, utilizing Pine/Xposed dynamic runtime hooks to modify Launcher, SystemUI, and framework behaviors without touching core system packages. 

Core Architecture 

- Pine Injection Engine: Executes modular DEX JAR hooks in-memory without breaking system partition integrity. 

- Manifest-Driven Settings: Addons declare configuration schemas in JSON, automatically generating intuitive Jetpack Compose / Material 3 preference interfaces. 

Icon Pack Manager 

- System-Wide Application: Apply third-party icon packs across Pixel Launcher, SystemUI notifications, and system dialogs. 

- Per-App Overrides: Select alternative icons for individual apps or extract/import icons directly from third-party APKs. 

- Dynamic Icon Protection: Preserves real-time updating of Clock and Calendar icons without reverting to stock assets after cache reloads. 

- Geometry & Shape Controls: Stretch icons into shapes, remove shape wrappers completely, scale masks, and configure foreground/background tints. 

Pixel Launcher Enhancements 

- Layout & Grid: Configure desktop grids, customize app drawer columns and row heights, and expand dock icons up to 12. 

- Clean Workspace: Selectively hide the bottom search bar, dock, Google Feed, and top smart widget. 

- Drawer Privacy: Hide installed system or user applications directly within the launcher without disabling the underlying packages. 

- Gestures: Double-tap on empty workspace areas to put the device to sleep (DT2S). 

Hardware, Display & Battery Telemetry 

- SurfaceFlinger Saturation: Hardware-level color saturation scaling from 0% to 200% via SurfaceFlinger transaction calls, complete with a quick-settings tile. 

- Auto-HBM: Configurable High Brightness Mode triggered by ambient lux thresholds (2,000 to 60,000 lux) with smooth brightness ramping, safety cooldowns, and thermal shutoffs (30°C to 80°C). 

- Extended Lockscreen Charging Diagnostics: Real-time charging telemetry on the keyguard displaying live wattage (W), voltage (V), current (mA), and battery temperature (°C). 

Recents Carousel Customization 

- Clear All Button: Enable a dedicated "Clear All" button with flexible placement options (floating bottom pill, replacing Screenshot, or replacing Select). 

- Carousel Geometry: Customize card static scale, spacing, transparency, and background blur radius (up to 300 dp). 

Overscroll Physics & Kinetic Scrolling 

- Customizable Physics: Fine-tune resistance, damping, pull coefficients, and fling parameters for scrolling. 

- Pre-built Profiles: Includes ready-to-use physics presets such as iOS Rubber Band, Elastic Band, Bouncy Ball, and Samsung Galaxy. 

- Axis Deformation: Independent X/Y scale distortion and zoom effects during overscroll gestures. 

Tensor G3 Thermal Profiles 

- Mode Switching: On-the-fly thermal profile switching for Battery and SoC (Stock, Soft, Medium, Hard, Off). 

- Thresholds: Soft (+5°C above stock), Medium (+9°C), Hard (+15°C), and Off (disables thermal throttling policies for maximum benchmark and gaming sustained output). 

CarrierConfig / IMS Manager 

- Client-Side Override: Forces carrier profile parameters for VoLTE, VoWiFi, Video Calling (VT), VoNR, Cross-SIM calling, and custom 5G thresholds directly on active SIM subscriptions.
