 # ADB Unlock, Screenshot & Scrcpy Tool
 
-A simple Python GUI application that uses:
-- **ADB** to unlock an Android device and take a screenshot
-- **Scrcpy** to display and control an Android device (non-blocking)
-- Tkinter for the GUI
+A user-friendly Python GUI application for managing Android devices. This tool allows you to unlock devices, take screenshots, mirror the device screen, and transfer photos with drag-and-drop functionality.
+
+## Features
+- **Unlock Devices**: Easily unlock an Android device using ADB.
+- **Take Screenshots**: Capture and save screenshots from the connected Android device.
+- **Screen Mirroring**: Use Scrcpy for real-time screen mirroring and control.
+- **Photo Transfer**: Drag and drop photos to transfer them to the connected device.
 
 ## Requirements
 
+### Software
 - **Python 3** (with Tkinter installed):
-  - On most systems, Python 3 will already include the `tkinter` module.
-  - If you need to install it separately:
-    - Debian/Ubuntu: `sudo apt-get install python3-tk`
-    - macOS (Homebrew): `brew install python-tk` (though often included by default)
-    - Windows: `tkinter` is usually included in the official Python installer.
-- **ADB** (Android SDK Platform Tools) available on your PATH.
-- **Scrcpy** installed and on your PATH (for screen mirroring).
-- A **`devices.json`** file in the same directory, containing your device serials.
-
-Example `devices.json`:
+  - Tkinter comes bundled with most Python installations. If not, install it using the instructions below.
+- **ADB** (Android Debug Bridge): Ensure it is installed and added to your system PATH.
+- **Scrcpy**: Install and add it to your system PATH for screen mirroring.
+- **Devices Configuration**: Create a `devices.json` file in the same directory as the script to store device serials.
 
+#### Example `devices.json`:
 ```json

+
+### Tkinter Installation (if not already installed)
+- **Debian/Ubuntu**: `sudo apt-get install python3-tk`
+- **macOS** (Homebrew): `brew install python-tk` (Tkinter is usually included by default).
+- **Windows**: Tkinter is typically included in the official Python installer.
+
+### Installation of ADB and Scrcpy
+- **ADB**:
+  - Download the Android SDK Platform Tools from [Google](https://developer.android.com/studio/releases/platform-tools).
+  - Add the folder containing `adb` to your system PATH.
+- **Scrcpy**:
+  - Installation instructions for various platforms can be found on the [Scrcpy GitHub page](https://github.com/Genymobile/scrcpy).
+  - Add the Scrcpy binary to your system PATH.
+
+## How to Run
+1. Clone or download the repository containing this script.
+2. Ensure `devices.json` is in the same directory.
+3. Run the script:
+   ```bash
+   python script_name.py
+   ```
+4. Follow the on-screen instructions to select a device and perform actions.
+
+## How to Use
+
+1. **Device Selection**:
+   - Select a device from the dropdown menu populated using `devices.json`.
+
+2. **Unlock Device**:
+   - Click the "Unlock Device" button to unlock the selected device.
+
+3. **Take Screenshot**:
+   - Enter a name for the screenshot (e.g., `screenshot.png`).
+   - Click the "Take Screenshot" button to save the screenshot to the default folder.
+
+4. **Screen Mirroring**:
+   - Set the maximum FPS for Scrcpy (optional).
+   - Click "Start scrcpy" to mirror and control the device screen.
+
+5. **Photo Transfer**:
+   - Drag and drop a photo file into the input field or manually provide its path.
+   - Click "Push Photo" to transfer the photo to the device.
+
+## Dependencies
+This project relies only on Python’s standard library:
+- `json`
+- `subprocess`
+- `os`
+- `tkinter`
+
+### No External Python Packages Required
+All required modules come bundled with Python. However, ensure:
+- `adb` is installed and on your PATH.
+- `scrcpy` is installed and on your PATH.
+
+## Troubleshooting
+- **ADB or Scrcpy Commands Not Found**:
+  - Ensure ADB and Scrcpy are installed and added to your system PATH.
+- **Tkinter Module Not Found**:
+  - Follow the installation instructions for your operating system to install Tkinter.
+- **Device Not Listed**:
+  - Ensure the device is connected and `adb devices` lists it.
