Want to reinstall apps that came with phone

Apple Built-in apps which come with any iOS update, can be redownloaded by installing a fresh copy of your iOS version.

To do that, create a full backup of your iPhone/iPad (1), then restore it to factory settings (you need a computer to perform this step) and, in the end, set it up as new (2).

When done, restore data from your previously made backup (3).

Follow the instructions provided in these support articles:

(1) How to back up your iPhone, iPad, and iPod touch – Apple Support

(2) Restore your iPhone, iPad, or iPod to factory settings – Apple Support

(3) Restore your iPhone, iPad, or iPod touch from a backup

For any further problems, contact Apple Support directly using this link:--> Get Support

Hello.

You can open the App Store and search for "Apple" to download stock apps and other apps developed by Apple.

I hope this helps.
