UPDATE 29/11/2016: The latest leaks indicate the Galaxy S8 will have 6GB of RAM and at least 256GB of storage. What is uncertain is if Samsung will bother with a microSD, or instead follow the Apple model of high-storage, but no external storage.
As to why 6GB of RAM and not more than that, it's likely it was the best hardware gain possible without causing too much issues where heating is concerned.
In the meantime, Samsung will also be offering a glossy black version of the Samsung Galaxy S7 just in time for Christmas.
Samsung acquired Viv, an AI created by the same people who helped make Siri. Viv has shown promise as an AI assistant, using natural language technology and even has the ability to create its own programming. Think of it as an AI that actually works.
The AI will be a star attraction of the Galaxy S8, and offer a new dimension to AI unseen so far on commercial smartphones.
With the bad rep created by the Galaxy Note 7, Samsung will need some positive buzz which is why for the first time the company is confirming features before the phone's actual launch.
There are rumours the phone might be delayed as Samsung wants to figure out the cause of the exploding Galaxy Note 7s and also wants to try and figure out how not to repeat its past mistakes with the new flagship.
Could Viv be the killer AI we have all been waiting for and must we prepare for our phones to be our new overlords? It looks like things could be looking up for Samsung.
