This checks whether your phone can run the inspection app. Walk round your home for about 10 minutes as if doing a real inspection: say which room you are going into ("going into the kitchen"), talk about what you see, and tap Photo now and then.
Try these on purpose during the walk: lock and unlock the screen once, switch to another app and back once, and press "Test voice" with your earbud in.
Nothing is uploaded. Everything stays on this phone until you choose to share the results.
