Some sellers on Alibaba already have Galaxy Note20+ cases ready to go. They show renders of the device which are based on incomplete schematics the front side was clearly left to the imagination, but the straight back and sides should be pretty accurate (since the back and sides are what the case covers).

Speaking of the sides, notice the curved screen. The left and right sides of the case go up only part way, the rest is screen. There are lips on the top and bottom that help secure the phone set up.
Samsung isnt going crazy with the curviness, though, theres enough room left for side-mounted bezels.

Moving over to the Galaxy Note20 cases, the sides of the case go all the solution to the front, so it will have a flat screen. This matches what weve seen in renders of the Note 20 and of the Note20+. This would be a detour from Samsungs strategy of exclusively using curved screens on its flagship phones (which dates back to the Galaxy S8).
The bottom side shows three major holes one for the USB-C port, one for the speaker grille and one for the S Pen (plus a small hole for the mic). The top is pretty bare with only a hole for a microphone.

Then theres the rectangular cutout for the camera island, but again since that isn’t covered by the case, case renders aren’t 100% reliable. So, its best to confirm with other leaks, which do declare that the Note20+ model will have a periscope camera as observed in the renders above.
