Find My iPhone apps have mysteriously been sending many livid people who lost their Apple smartphones to a Georgia home for a year. Since last year the mobile app used to find lost or stolen handsets has directed iPhone owners claiming they tracked their missing devices to the Atlanta couple's house.    

Michael Saba and Christina Lee have received up to four visits per month from strangers during the past year, claiming the Find My iPhone app had tracked their handsets to their home. It started in February 2015.

The people have showed up at different times of the day, include morning, afternoon, and late at night. It has happened over a dozen times, according to Cult of Mac.

Some of the mobile phone owners visited the couple's home with police officers. It once resulted in the search for a missing teenage girl and her Apple phone.

iPhone owners did not always believe when Saba and Lee claimed they did not have any lost iPhones. The Atlanta couple was concerned one day someone dangerous might knock on their door and then become violent.

It is unclear why people who lose their smartphones keep visiting the couple's home. The phones were sometimes Apple or Android handsets, and used different mobile carriers including Verizon, AT&T, Sprint, and T-Mobile.

Apple and Android phone makers, and mobile network companies have been contacted about the odd situation, according to International Business Times. However, they have provided no reply.

The Federal Communications Commission (FCC) has also been contacted about the issue. However, it has also not explained the technical glitch.

This year a few people have already contacted the Atlanta couple about missing iPhones.

Fusion reports the problem might be related to mobile tower "triangulation." A security analyst explained that smartphone-tracking apps use the tech to find missing handsets.  

Fusion notes that all mobile apps use the same Wi-Fi mapping data. The licensing company could have bad data in its database, which could include bad GPS data or someone using the same media access control (MAC) address at another location.

Apple originally released the Find My iPhone app in June 2010. It remotely tracks iOS devices and  Mac computers, and is now bundled with iOS 9.
