For the most part, it seems that we won’t be expecting any new accessories from Samsung, at least in terms of variety. The retailer alleges that Samsung will offer the Hyperknit cover, the LED View, Clear View, Alcantara, and Protective covers which have been offered for previous Samsung handsets.
However the retailer claims that Samsung could also introduce a new wireless charging pad for the Galaxy S9 handsets that will replace the current charging pad, and that we can also expect a new DeX pad. Other than that like we said, in terms of the lineup it doesn’t appear that it will be too different from its predecessors.
At the moment the rumors are claiming that Samsung could announce the Galaxy S9 and S9+ earlier than usual, possibly in February 2018. This is about a month earlier compared to the Galaxy S8 and S8+ which were announced in March earlier this year. In any case take it with a grain of salt for now, but if the February rumors are true then we should expect more details to be revealed soon.
