God's Eye was invented by Ramsey (Nathalie Emmanuel) sometime before the events of "Furious 7," and quickly attracted the attention of the sociopathic hacker-terrorist Cipher (Charlize Theron). Cipher hired the mercenary Mose Jakande (Djimon Honsou) to retrieve God's Eye on her behalf, but not before Ramsey sent it to a trusted friend in Abu Dabi for safekeeping.
Ramsey was briefly kidnapped by Jakande and subsequently saved by Dom's crew, who were operating at the behest of Mr. Nobody (Kurt Russell) and The Agency (apparently they were all in favor of giving a shady clandestine spy organization unconstitutional surveillance capabilities if it meant they could use it to beat up Jason Statham). Despite a few hiccups, Ramsey and her new teammates were able to secure God's Eye for The Agency and defeat Jakande for good.
In "The Fate of the Furious," however, Cipher steals the device for herself and uses it against Dom's former crew members (Toretto was working at the time for Cipher, for reasons far too baffling to get into here). Of course, she was eventually thwarted, and God's Eye was once again returned to The Agency.
