When you use an Android phone to connect to a wireless box, you encounter issues like green screen/mosaic.

Try the following methods separately:

1. Plug the wireless box into a wall charger or car; once the red light turns on, connect the wireless box's WiFi to your phone, then enter 192.168.50.2 into your phone's browser to access the backend. Then check for updates .

2. Use your Android phone to connect to Android Auto wirelessly, open your mobile browser, enter 192.168.50.2, try changing the resolution (try all the resolution options to see if there's a suitable one), and then see if the pixelation problem persists.

3. Change Android Auto Video Resolution (Developer)

1>Open the Android Auto app.

2>Scroll down and tap the "Version" section to view version information and permissions.

3>Continuously tap this section several times.

4>You'll be asked if you want to enable developer settings. Click "OK."

5>Tap the three-dot menu icon in the upper right corner.

6>Open "Developer Settings".

7>Go to "Video Resolution".
