@atokwameian: The screen protectors that come fitted to the Galaxy S10+ are designed to offer an extra layer of protection out of the box, however we do not offer free of charge replacements as they are not classed as an accessory. If you purchase a genuine replacement and visit a Samsung Experience Store or Support Centre, then an engineer can help you fit the screen protector. Alternatively, you may be interested in our official range of cases and covers: https://www.samsung.com/uk/mobile-accessories/all-mobile-accessories/?smartphones+cases+galaxy-s10
I removed mine after the first week of use and haven't put one back on since! Had my phone for a long time now and no issues with it.
