(Q) Worth an RMA? topic

I got my nexus on Tuesday, the next day I realised the power button rattles whenever I tapthe top right corner of the screen. The day after I found one single dead pixel. I ran an app to fix it overnight but it didn't.

Is this worth a RMA? I live in the UK if that makes a difference. Thanks!
