Samsung has been including two cameras in several of its big name products over the past few years and their inclusion here isn't surprising. On smartphones, the company generally uses two sensors to accomplish more accurate depth perception while other companies have used a similar setup to attain more accurate facial recognition features. The latter of those could be the reason for two cameras to be used here since that would enable any AI driven features based on that to work more effectively. The inclusion of full color renders, meanwhile, seems to suggest this product is actually significantly far into development rather than only existing as a concept — although that could turn out not to be the case.
