According to a report published online, the upcoming Samsung Galaxy S10 series will feature devices with the names "Galaxy S10 Plus," "Galaxy S10 Lite," and somewhat surprisingly, "Galaxy S10 Edge." The same report lists the flagship smartphones as having preinstalled transparent screen protectors. The post does not mention the expected 5G variant of the S10 line-up, though.
