Motorola is warning people not to add screen protectors to the new Razr, and says bumps and lumps under the screen are 'normal'

The Razr's hinge mechanism will likely give off a lumpy texture under the center of screen. Motorola doesn't say why, but Samsung's Galaxy Fold had a similar texture under the screen, too, which was a result of the foldable screen. Foldable smartphones don't have glass on top of the screens that make up the solid surface we're used to tapping and swiping with regular smartphones.

This should be a no-brainer for most people. You generally want to avoid sharp objects coming into contact with any smartphone. But with the new Razr's foldable display, you may want to take extra care, especially when the phone is unfolded.

The Samsung Galaxy Fold had a pre-installed protective coating that some tech reviewers tried to remove, so Motorola is making it extra clear that protective layer you see on the new Razr is meant to stay there.

Apart from the nostalgia factor and its gorgeous design, the appeal of Motorola's new Razr is that it can fold up into a smaller and more compact form than a traditional smartphone. Putting the new Razr away in a pocket or bag without folding it up first also seems like a sure-fire way to damage the hinge.
