While Samsung hasn't mentioned anything official but passing winks about its upcoming Galaxy S4 flagship phone, there's plenty of speculation to go around for everyone. Some of its major features are almost a given, but there's still quite a bit of cloudiness about which processor the Galaxy S4 will use - the latest rumor suggests a Qualcomm Snapdragon chipset might be used.
Korean Digital Times has put out a report suggesting that a Qualcomm Snapdragon chipset could be a mainstay of the Galaxy S4, not a Samsung chipset. The rumored CPU could be the quad-core Qualcomm Snapdragon 600, the same processor utilized by HTC's recently-unveiled HTC One smartphone. Of course, this is all rumor until Samsung releases the handset's official specs, so treat it as such.
The Galaxy S4 has also been linked to a couple other powerful CPUs, both from Samsung. A spec sheet showed up on the Internet showing the Galaxy S4 running on an Exynos 5440 quad-core processor - no slouch itself - but it's another possibility that really has people's mouths watering.
Back in January, Samsung showed off the incredible Exynos 5 Octa eight-core CPU and had everyone thinking: this will surely find its way into flagship lineups like the Galaxy S and Galaxy Note. The simple novelty of having an eight-core processor would give Samsung some powerful marketing clout in a smartphone world that is growing increasingly competitive. Sadly, the Digital Times report does go on to say that there are some power issues with the Octa chipset, and if it's true, it might mean Samsung will hold off on giving the Galaxy S4 eight cores.
Other rumored specs include a 5-inch 1080p Full HD display, a 13-megapixel camera, and Android 4.2. The smartphone should also come with some novel features like eye scrolling and touchless gesturing.
Samsung is expected to hold a Galaxy S4 announcement event in mid-March, and the dust should finally settle then.
