Samsung is said to be releasing two versions of the Galaxy S5, both carrying a 5.2-inch display and plastic body. The "Prime" model is said to have a 1440 x 2560 resolution with a 565ppi pixel density, and the "Standard" model could have a 1080 x 1920 pixel density with 423ppi. The "Prime" version is said to feature a 32-bit octa-core Samsung Exynos 5430 processor, and the "Standard" model is said to feature a 32-bit quad-core Snapdragon 800 processor.

The Galaxy S5 is also rumoured to carry a fingerprint scanner, 3GB of RAM, a 16-megapixel rear-camera, 2-megapixel front-facing camera, 3D gesture support, and a 2850mAh battery. We've previously seen a more polished TouchWiz user-interface leaked for the next-generation handset.

Samsung confirmed in January the Samsung Galaxy S5 will be launched around March or April, along with a redesigned Galaxy Gear smartwatch. The Galaxy Gear reportedly features a curved screen and a new design that will be less bulky.

"When we release our S5 device, you can also expect a Gear successor with more advanced functions, and the bulky design will also be improved," said Lee Young Hee, executive vice-president of Samsung’s mobile business, in January.
