Fujitsu’s F-Series flip phone is nicknamed the “uwaki keitai” or “infidelity phone” in Japan, where it is used by customers trying to hide their illicit romances.

The model has built-in stealth features that help users stay discreet, with a ‘privacy mode’ that hides all incoming calls, texts, and emails from any contact marked as private. This means that even if someone checks your phone they won’t find anything suspicious. Instead, a subtle change in the color or shape of the battery signs or signal bars alerts the owner that an ‘acquaintance’ has been in touch.
