Basically, 3D Creator lets you create 3D models with Sony's superb scanning tech: Introduction Video
Everything is explained on 3D Creator's official YouTube channel.
This app also includes a Live Wallpaper that you can setup to show any 3D model in your collection, which can then be rotated on your home screen.
BONUS: While you're in the app, go to Settings and tap "Software version" a few times to unlock "Developer settings".
Your device is compatible only if...

NOTE: If your device does not support Camera2 API, when starting the tutorial, the app will hang on loading the camera.

DOWNLOAD REMOVED DUE TO SONY'S REQUEST
You can still get the unmodified APK from APKMirror but it has to be a system app,
and if you don't have an Xperia device, you'll have to modify the AndroidManifest yourself.
Don't PM me with APK requests, and don't ask for the APK here, you will be ignored.
