It's an attempt to one-up Apple. Apple only has the iPhone 6, we are up to 7, see! But they forgot that the latest Apple CPU is called A8. They also have other phones called A3 and A5 (not available in the US, info here: http://www.phonearena.com/news/Samsung-compares-the-Galaxy-A7-A5-and-A3-in-new-infographic_id64718). So it can be seen as an attempt to copy BMW, using Audi moniker. Samsung, even in their thief costume, is still a terrible failure.
