And as the looming Galaxy S7 comes closer, rumours and speculations come abound, with the latest suggesting that Samsung's upcoming flagship will come with a unique magnesium build and Hi-Fi audio.

The Samsung Galaxy S7, which has been tipped off with a January 2016 release, is u to debut with a magnesium frame. Samsung may keep the glass back that first appeared in its Galaxy S6 to give it a more sophisticated look. Reportedly, the new frame will make it more durable and sturdier while also adding up to the aesthetic value of the up and coming flagship.

Furthermore, Samsung will also be equipping the Galaxy S7 with ESS Technology's Sabre 9018AQ2M chip to turn the flagship into a rocking powerhouse with Hi-FI audio quality. According to reports, the chip comes with a 129 dB signal to noise ratio, is capable of supporting PCM up 32-bit and 384KHz, as well as DSD 11.2MHz sampling.

Rumour also has it that the Galaxy S7's display will come with 4K resolution, although it's still unclear if it will have a similar approach as to what Sony did with the Xperia Z5 Premium. Other reports suggest that the flagship will come with a dual camera setup to please photography aficionados. Furthermore, the Galaxy S7 will come in two variants - one with a Snapdragon 820 chipset and an Samsung's Exynos 8890 processor. To provide more options, Samsung may also offer the Galaxy S7 with a 5.2-inch display and a 5.8-inch variant. 

Samsung unveiled the Galaxy S6 edge during Mobile World Congress 2015, but the South Korean tech giant may be looking to release the flagship as early as January in hopes to compete and stay ahead of the high-end smartphone race.
