Providing a precision fit to curved displays, the Alpha Flex Smartphone Screen Protector for Samsung Galaxy S21 5G from OtterBox is made to deliver strong screen protection that can flex and mold to the screen. The Alpha Flex is not made from glass, so it can't shatter or crack, but OtterBox's Crystal coating adds strength and ensures the clarity and touch responsiveness of the display remains unaffected. All of the tools needed for a quick and easy installation are included.
