Stop us if you've heard this one before: Amazon's getting ready to launch a phone. This is actually one of the longest-running rumors we've heard, with the first reports stretching back to 2012. So what's different this time? According to the Wall Street Journal, the company is already showing off prototypes of the handset to developers and is gunning to announce the device by the end of June with a September release. The report tells us that Amazon wants to differentiate itself from other top-of-the-line flagships by adding four cameras with retina-tracking tech, making it possible to project 3D images without needing glasses.
Rumors of a "Kindle phone" (or multiple phones) have been floating around the internet for ages, and this isn't even the first time we've heard that Amazon was working on a 3D-type display -- the Journal began reporting last May that the project would enable visuals that "seem to float above the screen like a hologram." Given how much smoke we've seen, there's quite likely fire. We wouldn't be surprised to see some news come out around the same time as Google's I/O developer conference, but we're more curious to find out exactly what Amazon plans to do with this retina-tracking tech and how developers will be able to take advantage of it. Needless to say, it certainly would add an interesting element to our already endless Instagram feed.
