That is shown both on the FP3 and the FP3+. You can hold them apart by external appearance: The FP3 has white lettering (which tended to peel and fall off) on the back cover, the FP3+ has it just in “relief” lettering (conclusion from the former ) without colour filling. Plus the FP3 is somewhat translucent black while the FP3+ is opaque black all over. And last but not least: The FP3 came with a black bumper that stretches around all edges of the device, but does not cover the back cover.
