Notification bar malfunctioning

[Dragosxz2compac]

The notification bar is pulling down by itself when I do other operations like typing or scrolling down in browser. It's extremely annoying as it completely blocks me from operating the phone 

What is the problem? And the solution?

I'm having this problem too. My phone keeps misreading my touch likes its broken. It looks mint brand new not a scratch.

Are these screens not tested to pressure like the pressure found in people's pockets? It would have been nice to know that a military style fully protective case was necessary for it to be USED LIKE A PHONE. I do have a case on it btw.

This isn't funny if my screen is broken and looks prestine that's a serious problem please try to contact me
