The Samsung Galaxy S6 was introduced by Samsung on March 1st, 2015. It marks the sixth generation of Samsung's Galaxy S line of Android smartphones. The Galaxy S6 was released to retail on April 10th of the same year in 20 initial launch countries. Other countries followed. It proceeds the Galaxy S5, launched in early 2014
The Galaxy S6 is offered in two variants: the standard S6 and the S6 Edge, with the only major difference being the shape of the display (the S6 Edge is curved). Both were offered in a variety of colors (availability depending on market) and with storage ranging from 32GB up to 128GB.
The Galaxy S6 marks a substantial change in design language and materials for Samsung, with the phone being made primarily of various metals and glass. Previous iterations were predominantly plastic. The Galaxy S6 does not feature a removable battery, and also lacks a microSD card slot for expandable storage - capabilities found on every previous Galaxy S phone.
Unlike many earlier Galaxy phones, Samsung chose to utilize the same system-on-a-chip for all Galaxy S6 and S6 Edge models across the world, sourced from its own in-house Exynos brand. The Galaxy S6 and S6 Edge are among the most popular smartphones Samsung has ever built, and perhaps more than any other Samsung smartphone at the time of their release represent a continued effort by the company to use as many homegrown components as possible.
The Samsung-designed chipset, modem, display, camera (though some used Sony sensors), memory, and storage offer a level of smartphone design and engineering integration rarely found in the industry.
