As the report say, the Galaxy S8 and S8 Plus will be available in Silver, Black and Violet colors. The Violet variation is for now not very common color for a Samsung flagship. For the cost of the devices, the Galaxy S8 will be priced at 799 euros while the S8 Plus 899 euros. If this rumor is true, this flagship will be more expensive than the last one, when the Galaxy S7 and S7 Edge were released. Back then, at their release, their cost was 699 and 799 euros respectively at their launch date.
So, because none of these information are of course, not confirmed by Samsung yet, we should only take them as a consideration. March 29 is also right around the corner, so we will have to wait a little bit more to see what Samsung will bring for us.
