How get back information I delete

If you're missing photos or videos in the Photos app on a mobile device, click here --> If you're missing photos or videos in the Photos app - Apple Support

- Check your Recently Deleted folder

If you were not using iCloud photos to sync your photographs then they may still be stored on another device or as part of a backup. You can restore the backup ( Restore your iPhone, iPad, or iPod touch from a backup - Apple Support ) to recover the photos but doing this will require erasing your device and restoring everything back to the time when you made that backup.
