Getting Ringtons and Wallpapers to Sound Settings?

[tecknomage]

I have a bunch of Wallpapers in my Pictures library and Ringtones on iCloud Drive.

I think the ringtones were uploaded from iCloud to my iPhone, but where I don't know.

How do I install Wallpapers and Ringtones so they show under Setup

My old Android had a [Add] button for Ringtones and Wallpapers in Settings.

If the wallpapers appear in your Photos app, you can use them on the iPhone.
Open the app, select the picture you intend to use as wallpaper, then tap the Share button:

On the next screen, slide until you find "Use as Wallpaper":

Now adjust the picture is necessary and tap Set:

Choose one of these afterwards:

And your new wallpaper will appear on your screen/s.

I don't know if it's possible to use ringtones from iCloud. Mine are purchased from iTunes Store, or synced through iTunes, which are the only ways to get them to the iPhone, afaik. I hope someone else can tell you more about it.
If you can use them on your iPhone, go to Settings - Sounds:

There, go to Sounds and vibration patterns, and select one of the options there:

If you can find your ringtones on the next screen, select the one you prefer:

It will be set up as sound for the feature you selected.
Hope that helps.
