An image of the Samsung Galaxy S10's screen protector has been leaked via Twitter by Ice universe. The tweet in question features the lone word "Beyond," which is the codename Samsung uses for the S10 line-up. As can be seen in the picture, the screen protector has barely visible bezels and there is no sign of the much-maligned notch.

Usually if there are black bezels on the protector then there need to be holes drilled out for the front camera and sensors, in this photo there is none visible, so either this means lack of a front camera, an UD front camera, or that the black bezels serve no particular purpose (or merely as a bumper for the actual glass edges as they're likely plastic) and are much smaller than the actual bezels on the device used to fit the camera and sensors. Somehow I suspect the 3rd scenario is most likely...
