How to establish a connection without enabling USB debugging on my device?

Normally, using scrcpy requires enabling USB debugging on your Android device. However, there are alternative methods to establish a connection without USB debugging. One option is to use a TCP/IP connection over Wi-Fi or LAN. This method requires your device and computer to be connected to the same Wi-Fi network or LAN. To set up a TCP/IP connection:

1. On your Android device, go to Settings > Developer options (if not visible, enable it by tapping 7 times on Build number in Settings > About phone).
2. Enable the "Wireless debugging" option.
3. Connect your device and computer to the same Wi-Fi network or LAN.
4. Run scrcpy with the -s <ip address of device> argument, replacing <ip address of device> with the IP address of your Android device.

Another option to connect without USB debugging is using a third-party tool called "adb over TCP." This tool allows you to establish an ADB connection over TCP/IP, making it possible to use scrcpy wirelessly. To use adb over TCP:

1. Install the "adb over TCP" tool on your computer.
2. Enable the "Wireless debugging" option on your Android device as described above.
3. Connect your device and computer to the same Wi-Fi network or LAN.
4. Run the "adb over TCP" tool on your computer, specifying the IP address and port number to connect to your device.
5. Run scrcpy with the -s <ip address of device>:<port number> argument, replacing <ip address of device> with the IP address of your Android device and <port number> with the port number specified in the "adb over TCP" tool.

Is a Wi-Fi connection supported as an alternative to USB for using scrcpy?

Yes, a Wi-Fi connection can be used as an alternative to USB for using scrcpy. As described in the previous section, you can establish a TCP/IP connection over Wi-Fi to connect to your Android device without USB debugging.

What are the potential security risks and precautions when using scrcpy without USB debugging?

There are potential security risks associated with using scrcpy without USB debugging, as it allows you to access and control your device remotely. Here are some precautions you should take:

• Ensure that your Wi-Fi network is secure: If you're using a public Wi-Fi network, avoid using scrcpy without USB debugging.
• Use a strong password for Wireless Debugging: Set a strong password for the "Wireless debugging" option in your Android device's Developer options.
• Only connect to trusted devices: Only establish a connection with devices that you trust.
• Keep your scrcpy server private: Run scrcpy with the --port <port number> argument to specify a non-default port number, making it less likely that someone else will connect to your device.
• Install a firewall: Consider installing a firewall on your computer to block unauthorized access.
