2. If you accidentally delete an application, you can retrieve it by entering the application name in the App store, and then download it. For example, if you delete "podcast" by mistake, enter "podcast" in the search bar of the app store, and click the cloud download arrow on the right after finding it.

3. It should be noted that when the software that comes with the system is deleted by mistake and downloaded again, the full name of the software needs to be entered in the search, otherwise it may not be found. It is also possible to enter the full name of the software or to find the software you are looking for.

4. For example, the following situation. At this time, you can try to enter "Apple" in the search bar, search for related software, click on the first software you find, and pull it to the bottom to find "other developer apps", so that you will see a familiar list. Pull to the bottom, find "Other Developer Applications" and click Enter. Look for the software you want to download in the list, and your own system software can generally be found here.
