One-Button 10-Minute UV-C Cycle
Everything about the sanitizing side is built around one button. Close the lid, press it, and the UV-C lamps run for 10 minutes before switching off on their own, with a beep to say the cycle is finished. There is nothing to set, no app and no timer to choose, which makes it easy to fold into a routine such as dropping the phone in when you get home. The limitation is coverage. The lamps light what faces them, and the underside of whatever sits on the floor of the box gets much less exposure, so owners who want the whole phone treated run a second cycle after turning it over. Samsung cites testing by Intertek and SGS against common bacteria, but results on a real phone depend on how much of its surface the light actually reaches, so clean off visible grime first, since UV works on surfaces it can see and does not remove dirt.
