To reset the default program to open on Android, you can follow these steps:
1. Open the "Settings" app on your Android device. You can usually find the app icon in your app drawer or by swiping down from the top of the screen and tapping the gear icon.
2. Scroll down and find the "Apps" or "Applications" option in the settings menu. The name may vary slightly depending on your specific Android device.
3. In the Apps menu, you will see a list of all the installed applications on your device. Look for the app that you want to change the default program for and tap on it.
4. Once you're on the app's info page, you may need to scroll down a bit to find the "Open by default" or "Set as default" option. Tap on it.
5. You will now see a list of actions or file types that the app can handle. For example, if you want to change the default web browser, you may see options like "Go to supported URLs" or "Open links."
6. Tap on the option that you want to change the default program for. For instance, if you want to change the default browser, tap on "Go to supported URLs" or similar.
7. Android will now display a list of available apps that can handle the selected action or file type. Choose the app you want to set as the new default, or if you want to clear the default program and choose each time, select "Ask every time" or a similar option.
8. After selecting the desired app, you can go back to the home screen or any app and test if the default program has been successfully changed.
By following these steps, you should be able to reset the default program to open on your Android device without any issues.
