Fujitu’s old F-Series flip phones, also known in Japan as “infidelity phones”, are still used by a specific demographic subset: “love-cheaters”. The reason is these old flip phones feature a privacy setting that allows users to hide calls and text messages from curious eyes.
The recent series made by Fujitsu are not as discreet as the older F-series, some of the unfaithful users say. The ageing phones feature a nearly invisible ‘privacy mode’ that hides missed calls, emails and texts from any contacts that are designated as private, the international press reports.
The only indication that a designated private person has called is a slight change in the colour or shape of the battery level icon or the network signal antenna bars are shown. In order to turn off the privacy mode, the user has to enter a secret combination of keys. The code will reveal the received calls and text messages and allow the access to voicemail.
A Japanese pick-up artist and blogger who uses the nickname “Bakanabe” said he still keeps the old Fujitsu phone because women he dates might check his missed calls, messages or emails when he is not around.
“With Fujitsu’s ‘privacy mode’, they can’t see that information at all. The key is to give off the impression that you’re not locking your phone at all,” he said.
Another Japanese blogger, nicknamed “Poza”, who claims to have three girlfriends at the same time, said he uses the privacy feature in order for his affairs to remain secret. Aside from the Fujitsu phone, which he owned for five years, Poza also uses an iPhone. However, giving up his old Fujitsu flip phone would be “unthinkable”.
“In terms of keeping my cheating hidden, this does more than enough,” said Poza, who declined to give his real name but said he worked for a design company in western Japan.
