Light Sensor on 6.5 Wonky As & Should the Screen/Slide Part be Wobbly?

[Lupin Saiko]

So I got my Touch Pro a couple days ago and I almost immediately installed MightyRom6 so I dont really remember if this problem existed on stock or not but in calls the light sensor or some other thing keeps turning the screen on and my cheek inevitably either ends the call or opens an amazing number of apps. I ended up just disabling the sensor via Advance Configuration and just manually lock the device when I go into calls but even then it still seems to turn back on rare occasions. Is this a known bug? Is there a fix? It is highly annoying. TIA

UPDATE:
Should the Screen/Sliding Part of the phone be wobbly when it is slid in/over the keyboard? Mine is and the center buttons top part is also slightly caved in. If I hear the wobbling screen should be solid I might just take this back and get another since it seems it might just be an incredibly bad unit.
