HarmonyOS
From the Audiovisual Identity Database, the motion graphics museum
(2020-)
Logo: A neon white circle rises out of a pitch-black floor (ala the Odyssey Entertainment logo) before fully revealing itself to be an "O" in the "HarmonyOS" text, which it illuminates slightly. The camera zooms out and the text brightens, revealing itself to be the text. A blue line draws itself in under the "O" after the logo finishes. A dark shine wipes across the text as the device boots up.
Technique: CGI.
Music/Sounds: A synth note which rises in intensity, followed by a two-note chime tune.
Availability: Common. Seen on Huawei HarmonyOS phones after the Huawei 2018 bootscreen.
