I got my N4 this past Friday, haven't done anything except installing a few apps (like Dolphin, angry birds etc) from the Play store, no rooting or custom roms or anything like that. However, I've noticed that the phone still gets VERY got, upon installing a temperature monitoring app, it seems that the CPU is running at 50-59 degrees Celcius at certain times. WTF? should I RMA or is this normal?
