Using Shizuku for More Advanced Tweaks

Shizuku allows apps to use system APIs directly with elevated privileges without requiring root. You can grant permissions and perform certain actions that usually require root by using Shizuku in conjunction with ADB.

Install Shizuku:
- Download and install the Shizuku APK from the Shizuku GitHub repository.
Start Shizuku via ADB:
- Connect your device to your PC via USB.
- Run the following command:
```
adb shell sh /sdcard/Android/data/moe.shizuku.privileged.api/files/start.sh
```
Grant Permissions via Shizuku:
- Open Shizuku and follow the instructions to configure it.
- Use the Shizuku interface to grant permissions and manage your apps.

By following these steps and using these commands, you can tweak and customize your Android device using adb shell, even without root access.
