There is another thread which goes into quite a bit of detail. I’ve got one and like it. Fantastic screen and quick enough. Camera could be better and is slow to focus, apparently this is a software issue and is being fixed. Some people have reported issues playing music but I’ve not found anything yet. My main issue with it is the speaker is very quiet, to the point where you cannot hear the phone ring when outside.
Overall I like the phone though and at nearly 300 quid less against the iPhone for something arguably as good.
Nexus are for phone geeks who like to tinker, do if you like a polished end product then it may not be for you.
Edit to add I mean the external volume. Calls sound clear and people say they can hear me OK, so that’s one better than an iPhone(which are terrible phones IMHO)
