Samsung is prepping a bunch of new tablets - from the flagship Galaxy Tab S4 to a refresh of the Galaxy Tab A 10.1 (2018), the Galaxy Tab A2 (10.5) and Tab Advanced2 and the star of this story - the Galaxy Tab A 8.0 (2018).
The Galaxy Tab A 8.0 (2018) has been rumored to be a tame refresh of its predecessor - the key differences being a removal of the physical home button (in favor of on-screen one) and a slimmer profile, thanks to thinner bezels.
An official-looking render has surfaced, visualizing what could prove to be the Galaxy Tab A 8.0 (2018). Judging by the image, the Galaxy Tab A 8.0 (2018) will have curved glass on the front and a uniform backplate - most likely plastic.
By the looks of it, there's no Bixby button.
Here's a render of the Galaxy Tab A 8.0 (2017) and the Galaxy Tab A 8.0 (2018) side by side. The older tablet has a larger profile overall.
The homescreen of the Galaxy Tab A 8.0 (2018) shows a date of August 9, which coincides with the Unpacked event that will likely see the Galaxy Note9 and Galaxy Watch announced, hinting that the Galaxy Tab A 8.0 (2018) and possibly the Galaxy Tab S4 could piggiback the event too.
