According to the pictures, it looks like the Galaxy S5 Mini sports exactly the same design as the Galaxy S5, with the same rounded corners and perforated pattern on the back panel. It also looks like that Samsung has not compromised on core features and has kept the fingerprint scanner and the heart-rate sensor, both which are unique to the Galaxy S5. There's a rubber gasket attached to the inside of the back cover, which hints towards the device being water-resistant. However, unlike the Galaxy S5, there is no flap covering the USB port, so we are not sure if the device is indeed IP67 certified.
Spec-wise, the Galaxy S5 Mini is equipped with a 4.5-inch 720p (720×1280) Super AMOLED display, an unannounced Exynos 3 Quad (Exynos 3470) SoC clocked at 1.4GHz, Mali-400 MP4 GPU with a clock speed of 450MHz, 1.5GB RAM, 8 Megapixel primary camera sensor with 1080p Full HD video recording and 2.1 Megapixel front facing camera. The device features 16GB of internal storage, which can easily be expanded via a MicroSD card.
On the software side of things, the device runs on Android 4.4.2 KitKat with Samsung's latest Magazine UX TouchWiz UI interface layer on top of it. Tipster also mentions that all the Galaxy S5's software features are present on the Mini, including: Ultra Power Saving Mode, Private Mode, Kids Mode etc..
