Based on these leaked specs, the Samsung Galaxy S5 Zoom will be equipped with a 4.8 inch SuperAMOLED screen with resolution of 720 x 1280. Under the hood is a six-core Samsung Exynos 5 Hecta SoC. The Mali-T624 GPU handles graphics and 2GB of RAM is on board. A microSD slot comes with the unit, and Android 4.4.2 is installed out of the box. The camera will feature a 20.2MP sensor with OIS, a Xenon Flash and a 10x optical zoom. That compares with the aforementioned 16MP snapper on the back of the Samsung Galaxy S5, which will feature an LED flash. The front-facing shooter on the "Zoom" will contain a 2.1MP sensor.
Just because the phone is designed for those who focus on photography (pardon the pun), it doesn't make this model a slouch by any stretch of the imagination. The Samsung Galaxy S5 Zoom was put through the AnTuTu benchmark test where it scored an impressive 33,252. Keep in mind that this result was achieved using test software, so a score using the final build might differ.
