I pierced my Sonic Mini 8k S FEP sheet and was sure that the screen was toast. Well, Phrozen has wisely installed a screen protector from the factory on this model! Yay! So, here I am replacing the factory FEP with some nFEP from Amazon. I also am installing an aftermarket screen protector that was purchased for a Sonic Mini 8k on to the Sonic Mini 8k S. Here's my process.
