Why is there thin black line out of nowhere and it new.

[AC Question]

It's the two day after I bought my new phone droid maxx 2 and I have case and screen shatter proof on it, and there's a thin black line horizontally. It never been exposed to shock or water.

Welcome.

Occasionally, the glass of a phone screen can apparently crack or shatter for no obvious reason. This has been reported by owners of various devices. Explain what has happened to the retailer or the manufacturer, and request a repair or replacement device.
