You see change but In my Max's nothing wrong with that, this perfectly assembled x up and down as much there and when it reaches 0.5 mm.
And on the screen do not "yellow part" is nuclear white hehe.
I would not expect much from you, and if you are within the 15days you exchange it for a new one and open it in the store.
If you do not touch my warranty to die ...
Greetings and good luck!
