  - 新增视频码率设置页面，可读取默认码率，并为 8K、4K、FHD 等录制规格设置自定义码率。
  - 部分模式开启 HDR10+ 后录制时可能无法实时预览 HDR 效果，保存后可在相册查看实际 HDR10+ 效果。
  - 8K60 与 UHD240 对性能和散热要求较高，实际帧率和流畅度取决于设备芯片、温控和散热状态。

### 兼容性

- 需要 Samsung / One UI 设备。
- 需要 LSPosed。
- 当前主要在 One UI 8.0 环境测试过，请尽量保持系统组件、三星应用和模块本身为最新版本。
- 不同机型、地区包和三星应用版本可能存在差异，隐藏功能不保证在所有设备上都能稳定工作。

### 构建

如果项目所在路径包含中文或其他非 ASCII 字符，建议先把项目上级目录映射到临时盘符再构建：

```powershell
$projectRoot = Resolve-Path .
$workspaceRoot = Split-Path $projectRoot -Parent
$projectName = Split-Path $projectRoot -Leaf
cmd /c "subst W: `"$workspaceRoot`""
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ("W:\{0}\build-v50.ps1" -f $projectName)
```

构建脚本会把最终 APK 复制到项目上级目录：

```text
..\MyFilesWebDavPopupLsp.apk
```

### 安装

```powershell
$projectRoot = Resolve-Path .
$workspaceRoot = Split-Path $projectRoot -Parent
adb install --user 0 -r (Join-Path $workspaceRoot "MyFilesWebDavPopupLsp.apk")
```

### 说明

- `build/` 目录已被 git 忽略，不会上传到仓库。
- 当前仓库保留实际工作中的项目结构，没有改写成 Gradle 工程。
- 这是非官方模块，涉及 LSPosed hook 和三星隐藏能力，使用前请自行评估风险。

## English

### Features

- Samsung My Files WebDAV support
  - Adds WebDAV to the network storage flow, with compatibility paths for older and newer My Files builds.
  - Supports adding accounts, browsing directories, creating folders, deleting, uploading, downloading, copying, and moving files.
  - Includes compatibility fixes for menu injection, existing WebDAV entries, transfer actions, and completion jump prompts.

- Expert RAW enhancements
  - Unlocks hidden 200MP ultra-high-resolution support for Galaxy Expert RAW, mainly for Ultra devices.
  - Adds S23 Ultra guards for newer Expert RAW builds where unsupported 24MP quick-setting resources can crash startup.
  - Keeps the S24 Ultra path that has already been tested.

- Samsung Camera pro video enhancements
  - Unlocks HDR10+ for Pro Video 4K120 and FHD120.
  - Unlocks Pro Video 8K 24/30/60fps and HDR10+ for those modes.
  - Adds slow-motion UHD 240fps support.
  - Adds a video bitrate page for reading default bitrates and overriding 8K, 4K, and FHD recording bitrates.
  - Some HDR10+ modes may not preview HDR during recording; the saved video should be checked in Gallery.
  - 8K60 and UHD240 are performance and thermal heavy, so actual results depend on the device, throttling, and cooling.

- NFC screen-off card tapping
  - Adds a dedicated switch for allowing NFC card requests while the screen is off.
  - Disabled by default.

- Bixby OpenAI integration (beta)
  - Lets Bixby call custom OpenAI / DeepSeek compatible Chat Completions APIs.
  - Supports custom endpoint, model, API key, and related parameters.
  - Still experimental.

- One UI Home icon and label customization
  - Injects an entry into One UI Home settings.
  - Supports app search, image selection, cropping, icon shape, and corner radius settings.
  - Supports per-app launcher label overrides.
  - Adds a font settings menu for label font file, bold, italic, color, and gradient effects.
  - When gradient is enabled, labels use gradient text instead of a separate solid color.
  - Includes quick restart for One UI Home.
  - Avoids `onDraw` and per-frame refresh paths to reduce launcher lag and folder icon reuse pollution.

- System font customization
  - Adds a local font entry to Samsung Settings font style page.
  - Supports importing multiple `.ttf` files.
  - Imported fonts appear in the original font list and can be selected, deleted, and managed.
  - TTF only for now.

- Custom fingerprint icon
  - Replaces the fingerprint icon shown by system biometric UI paths, including lock screen and authentication dialogs.
  - Supports Lottie JSON animations and static images.
  - Bundles 9 default Lottie materials that cannot be deleted.
  - Supports importing user materials, looping live preview in the list, and long-press deletion for user-added materials.
  - Supports play-once and loop playback modes.
  - Links to [LottieFiles free animations](https://lottiefiles.com/free-animations).

- Touch high sampling rate
  - Adds a switch that attempts to send Samsung TSP high-sampling policy for finger touch.
  - Shows live refresh rate in the UI.
  - Tries to reapply after screen-off to screen-on transitions.
  - Charging may prevent high sampling from taking effect, and the UI notes this limitation.

- Global pass-through charging
  - Uses the Game Booster “pause USB PD charging while gaming” mechanism as a global switch.
  - Disabling the switch restores the system default behavior.
  - Adds an app shortcut for toggling pass-through charging from the launcher long-press menu.

- Charging display and sounds
  - Customizes SystemUI charging text with variable templates.
  - Supports custom plug-in and unplug sounds.
  - Includes buttons for reading and previewing the current system charging sounds.
  - Handles lock screen and AOD display paths separately.

- Device Health Manager
  - Shows Samsung Device Health Manager Service thermal, battery, anomaly detection, and background restriction state.
  - Provides common control switches.

- Dual app list extension
  - Attempts to extend the dual app candidate list to installed non-system apps.
  - This depends on Samsung system behavior and may vary by version.

- Log switch
  - Adds a main-page log output switch.
  - Disabled by default to reduce LSPosed and local diagnostic log spam.

- GitHub update check
  - Shows current version and latest GitHub Releases version in the main UI.
  - Provides update status and a GitHub repository link.

### Compatibility

- Samsung / One UI device required.
- LSPosed required.
- Currently mainly tested on One UI 8.0. Keep Samsung apps, system components, and the module itself updated.
- Hidden Samsung features may vary by model, region, and app version.

### Build

If your checkout path contains non-ASCII characters, map the parent workspace to a temporary drive letter before building:

```powershell
$projectRoot = Resolve-Path .
$workspaceRoot = Split-Path $projectRoot -Parent
$projectName = Split-Path $projectRoot -Leaf
cmd /c "subst W: `"$workspaceRoot`""
powershell.exe -NoProfile -ExecutionPolicy Bypass -File ("W:\{0}\build-v50.ps1" -f $projectName)
```

The build script copies the final APK to the parent directory of the project:

```text
..\MyFilesWebDavPopupLsp.apk
```

### Install

```powershell
$projectRoot = Resolve-Path .
$workspaceRoot = Split-Path $projectRoot -Parent
adb install --user 0 -r (Join-Path $workspaceRoot "MyFilesWebDavPopupLsp.apk")
```

### Notes

- `build/` is ignored and is not committed to the repository.
- This repository keeps the real working project layout and does not rewrite it into a Gradle project.
- This is an unofficial module that relies on LSPosed hooks and hidden Samsung behavior. Use it at your own risk.
