If you don't want to use USB debugging or enable developer mode on your Android device, there are still a few alternative methods you can try to screen mirror your device to your desktop:
1. Third-party Apps: There are various screen mirroring apps available on the Google Play Store that allow you to mirror your Android device to your desktop wirelessly. Some popular options include ApowerMirror, AirDroid, and TeamViewer QuickSupport.
2. Chromecast: If you have a Google Chromecast device connected to your desktop and your Android device is on the same Wi-Fi network, you can use the "Cast" feature to mirror your Android screen to your desktop.
3. Miracast: If your desktop supports Miracast, you can use this wireless display standard to mirror your Android device's screen to your desktop. Check if your desktop has Miracast support and follow the instructions to connect your Android device.
4. Vysor: Vysor is a Chrome extension that allows you to mirror your Android device's screen to your desktop. It doesn't require USB debugging, but it does need a USB connection between your device and desktop to establish the initial connection. Once connected, you can unplug the USB cable and continue the screen mirroring wirelessly.
5. HDMI/MHL Cable: Some Android devices support HDMI or MHL connectivity. If your device has this feature, you can use an HDMI or MHL cable to connect your Android device directly to your desktop's HDMI input.
Remember that the availability and functionality of these methods may vary depending on your Android device and desktop setup. It's always a good idea to check the compatibility and requirements of the method you choose before proceeding.
