strange noises and heat

[uselessChiP]

Hi, i noticed that my nexus 7 makes strange noises from the area near the back camera, sometimes you can hear them ever if you have the tablet at a regular distance from your ears and also every time i stop using/change camera the back camera makes a clicking sound, are those sounds normal or my tablet has some problems?

Also the tablet become easily hot I think it becomes hotter that the 2012 version when playing, in this ok?

I have the same issue . I charged it for the first time and both charger and tablet starting emitting some noise. I immediately removed the connection. I still hear faint noise from the back of the nexus 7 . should I return or wait till sometime
