Got the GN on Thursday and generally happy with it. However, I have a few issues that if not resolved will mean I need to think about either exchanging the phone or returning it. Issue one seems to the the length of time before it starts to indicate it is mains charging. Minor I know, but still annoying. Issue two however is worse. The screen does not stay off! I have set the screen to auto-off after 30 seconds. However, if it automatically goes off, or I switch it off, it turns it self on again after 7-10 seconds. I have tried different wi-fi settings, different settings for notification etc but nothing seems to change it. It just comes back on. Is anyone else finding this?
