Here's a juicy bit of news from the Samsung camp. Samsung recently trademarked the name Galaxy Alpha. Insider sources have commented on this upcoming future device. It turns out this will probably be the final commercial name of the previously rumored Galaxy F/Galaxy S5 Prime.
Just as rumored previously, it will supposedly include a metal body, but new details point to it being ultra-thin at just 6mm. On top of this, the phone is rumored to be only 4.7-inches and include an Exynos 5 Octa processor.
Additionally, these same sources suggest Samsung will release this Galaxy Alpha in the August timeframe, which is meant as a pre-emptive strike against the upcoming iPhone 6. The sources of this intel also indicated the phone has been internally called "the card-phone" because of its ultra-thin size. Samsung has so far refused to comment on these rumors or the trademark.
Of course, it's worth noting that previous rumored indicated the Galaxy F device would likely come with a 5.25-inch display, so this is the first time we are hearing indications of a smaller one. We will keep you updated with more details.
