Google has partnered with Disney to develop an augmented reality app based on the ARCore platform. It’s called The Mandalorian AR Experience and allows you to host a real Mandalorian. Or baby You, but it will be available with the next updates. Users can interact with characters and photograph them in their own living room.
Unfortunately, only owners of certain 5G smartphones can install the app. The full list can be seen at this link. Google notes that more devices should receive support soon. If your device is on the list but in Google play, you cannot download the application. You can download the APK installer.
