The device is said to come in both metal and plastic versions with the metal version costing about 800 euros and the plastic version costing about 650 euros.
The S5 will reportedly feature an AMOLED display with a resolution of 2560x1440. The size of the screen is still unknown but it's expected to be around 5.25-inches. The back sports a 16MP camera. Depending on whether you get the LTE version or not, the S5 will either be powered by the Exynos 6 processor or a Snapdragon 805.
While the Exynos 6 CPU was expected - which will likely be capable of operating all eight cores simultaneously - to power the handset, it’s only just been confirmed that the S5 will become one of the first smartphones to sport the Snapdragon 805 CPU, which should offer considerably higher performance than the Snapdragon 800 in the Galaxy Note 3, especially in the graphics department. It’s unclear what factors will decide what processor Samsung uses on which model – the metal version will likely have 64-bit support with the Exynos 6 processor, while the plastic model could be powered by the Snapdragon CPU (we’ve been told that LTE isn’t an issue for the Exynos CPU anymore, so we could see a change in tradition and find the plastic version of the phone with only the Snapdragon CPU in every country.)
For its operating system, the S5 will run Android 4.4 KitKat. Samsung will most likely announce the device in March, followed by a launch in April. SamMobile says they're still unclear on a few details, such as the amount of RAM, battery capacity, and whether photos will be more blur-free through hardware OIS, but those details are expected to surface in the coming weeks.
Additionally, Samsung is said to be readying the Galaxy S5 mini and Galaxy S5 Zoom for launch sometime after the Galaxy S5, with an official unveiling taking place sometime in June and May respectively.
The Samsung Galaxy S5 will likely be the main competitor to Apple's iPhone 5s until Apple unveils it's next generation smartphone which is expected to debut in September.
