Edge panel capability is the same AFAIK so I would assume it would still work. The manual also still lists it.
Well, maybe I lied. Just enabled the CNN edge feed and I'm not getting anything when the screen is off. I checked both the Verizon and generic S8 manuals and they make no mention of the edge rub. But, I know I read that somewhere in the last two or three days. A review of the "new" feature for the S7e shows an "information stream" toggle that had to be turned on. I don't see that either on the phone or in the manual. Looks like another lost feature.
