Motorola Moto G 2nd Gen - Lines on the glass?

A

AC Question

Hello everyone,

Just got my new Moto G 2nd Gen and noticed that on the glass covering the screen, there are lines and lines of tiny symbols (they look like an ! but turned on its side). They are quite hard to see but with the screen off and under a bright light are faintly visible.

They appear both when the screen is on and off and only cover the part of the phone which is the screen display.

I was wondering if this was normal - part of the protective coating perhaps? If someone could let me know, I would be very grateful.

Thank you :)
