Xperia Z3+ Dual, Lines across the screen

[Binder42]

I just recieved my new Xperia Z3+ Dual E6533 And these lines appear across the screen when watching film clips.

The screenshot below is from Youtube

It seems to dissappear when I turn off X-Reality

I also noticed small white dots appearing in the background for a second after flipping to a new home screen. 

X-Reality does not seem to affect this issue.

I have tried factory reset and updated to the latest android version.

Other than this, the device is gold.

Should I return the phone? or can it be resolved?

Thanx. /Tony

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.
How to backup?

If the issue should still remain you should contact the seller.
