Exactly, Dave! I for one have changed an ambiance exactly once. When I replaced the stock wallpaper with my own photo. Never used any of Jolla's supplied alternative ambiances.

Jolla seems to consider a quick switching between ambiances one of their unique selling points. They had a brilliant idea with their first phone to use replaceable back covers with connectors to enable various expansion functions. And what did they use it for? Ambiances. A complete misfire.
