Samsung Galaxy S6 Edge was well-received for its unique design and high-end specifications, but the upcoming successor is going to lift the flagship standards higher. It is widely believed that Samsung has already started working on Galaxy S7 and Galaxy S7+ smartphones, slated for a February release. The latest rumours suggest that the new flagship will use magnesium alloy for durability and strength.

The new information on Galaxy S7 comes from several sources within Samsung's supply chain, Phone Arena reports. The new flagship will be a major design upgrade as compared to Galaxy S6, which uses an aluminium frame and glass back. Galaxy S7 is going to be a full metal flagship with a unibody design.

By using magnesium alloy, Samsung will be able to shed up to 65% of the device's weight and make the handset 2.8 times stronger as compared to the current flagship. According to GSM Arena, Galaxy S7 will finally overcome heating issues as magnesium does not become as hot as aluminium.

The Korean sources also revealed that Samsung received magnesium alloy case samples from the maker of 6013 series aluminium metal frames used in Galaxy S6 series. Taking hints from these rumours, we can expect Galaxy S7 to finally adopt the latest iPhone design strategy, which uses 7000 series aluminium. Samsung is likely ditch the glass back in favour of magnesium alloy construction.

Apart from this, earlier reports have reportedly hinted at Galaxy S7's specifications as well. The Korean tech giant is expected to launch two variants of the flagship, Galaxy S7 and Galaxy S7+. Clearly, the difference in both handsets will be the size of the displays.

A recent leak on AnTuTu benchmark site revealed a mysterious Samsung device, named Lucky, which packs a 5.7-inch Quad HD display, 4GB RAM, 64GB memory, 16MP rear-facing dual camera and 5MP front shooter. Also, Samsung will use an upgraded in-house processor, Exynos 8890 alias M1 Mongoose chipset, clocking speeds at 2.7GHz. These specifications are right for a flagship handset and Galaxy S7 is the perfect fit.
