That is vey strange because the Apple.com website states that a model A1387 is a 4S. How can that be wrong?

Specifically: at Identify your iPhone model - Apple Support

it states:

iPhone 4s

Year introduced: 2011
Capacity: 8, 16, 32, and 64 GB
Colors: Black and white
Model number on the back cover: A1431, A1387, A1387

They are so certain, they state it twice : )

Force restart your iPhone.


Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.


Then tap Settings > General > Software Update



If that doesn't help, make sure your Mac is running the latest version of iTunes.


You can do that by clicking your Apple  top left in your screen.


From the drop down menu click: App Store

After the App Store opens, select Updates from the menu top of the App Store window.
