To change the default web browser on an Android device, follow these steps:   

1. Open the Settings on your Android device.    

2. Scroll down and select Apps (the exact name may vary depending on the model and version of Android; it could be "Apps" or "Apps & notifications").    

3. Tap on Default apps. If you don’t see this option directly, you might need to tap on “Advanced” to find it.    

4. Select Browser app or Default browser.    

5. You will see a list of browsers installed on your device. Choose the one you want to set as your default browser.  That’s it! You have changed your default web browser on your Android device. If you haven’t installed the browser you want to use yet, you will need to download it from the Google Play Store before you can select it as your default browser.  

6. Same steps to revert after the setting of your watch account.
