It seems to be the 5G mmWave antenna that is for US-based phones only
It looks like a potential button or SIM/SD tray... But I don't know how to reference it for a Google search. And the teardowns I've reviewed completely ignore it.
What is this plastic piece on the bottom right side of the S22 Ultra?
Solved! Go to Solution.
I don't think I'm a fan of the back cover coming off and exposing the cameras. Unless you do it in a clean-room, dust could potentially settle on the lense and cause issues for pictures. This happened to my S20 Ultra after I got water inside and uBreakiFix told me that opening the cameras would possibly affect my pictures... And it did when I would have sun flare on the lense
