As you can see in the image to the right, Blass has tweeted out a new render of the upcoming phone which comes in a midnight black finish as one of its options. The image doesn’t really reveal anything new, and in fact it seems to be in line with some of the earlier leaked renders which seems to show off the phone’s long-ish display, which presumably will stick to the same display aspect ratio of the Galaxy S8.
For the most part it also seems like Samsung will be sticking to the same design as the Galaxy S8, which isn’t really a bad thing since many do seem to like the design of the Galaxy S8 to begin with. Also from what we can tell from the render, there seems to be a button on the left side of the phone which could be the dedicated Bixby hardware button.
In any case take it with a grain of salt for now, but like we said the phone will be announced on the 23rd of August so we won’t have to wait much longer for it to all become official.
