[Q] Screen ripple topic

Hello
I have noticed that my Moto G (1st gen) has a problem where if you touch the screen you can see a "ripple effect" in the center of the screen, it's get more noticeable as you press harder, but even if you press light touches it's still visible somehow but very little.
I have searched the forums and found people having this issue with the 2nd gen of the device: http://forum.xda-developers.com/moto...stion-t2947732

here is a picture of the problem some guy posted (in my device it's always presents in the center of the screen no matter where i press):

Can you please check if your device has this problem too?
Make sure brightness is highest and test in while you viewing black image: http://images2.layoutsparks.com/1/23...black-page.jpg
