## Final report

I recorded one video with the camera app: video mode, shutter to start, then shutter to stop after a couple of seconds. The camera's filmstrip lists exactly one new item, "Video taken on Oct 15, 2023 15:34:38", with a play control, so the recording is saved in the gallery. The first shutter tap at launch only dismissed the mode list and took a stray photo, which I deleted; the filmstrip now shows just the video.
