Mine came with one. I spent days trying to figure out why the fingerprint reader barely worked. Then I removed the screen protector which turned out to be just a thin plastic sheet. Now awaiting a TPU screen protector.
TPU protector arrived and was installed and the fingerprint reader still works fine without even being reprogrammed. Not sure if different factory installed protectors are installed in different markets but the one I peeled off was cheap thin flexible plastic.Strange, my fingerprint reader works first time, every time with the screen protector that came with it installed. If you had problems with that, I'd suggest the same will apply with any other you put on your phone.
