How to modify the open mode of Android phone?

The open mode of Android system is registered by the application. Browsers such as UC will register how to open the URL. Just like listening to music every day, these players will register the MP3 on mode.

When registering multiple files, an application selection box will appear for users to select the appropriate file to open. For example, if you install UC and Dolphin Browser, the default Google Browser, UC and Dolphin will appear at the same time when you open the URL of SMS. You can choose one of the three or choose one as the default.

After selecting the default file, do you want to open it with other tools that also register the file? The solution is simple. Go to Settings-Applications, find the application you set as the default, and click "Clear Default Settings".

You can find the program to open the file in Settings > Application Management, click it, look down, clear the default settings, and it's OK. What about other ways to open files? PS: Actually, when you check the box as the default mode, are there any tips on how to restore it under the box? .
