Yes, the sensors issue is annoying.
But I have a few other Problems that annoy me more.:

1. Adjust the volume during a call don't work,
2. playing mp3: the app chrashes,
3. playing videos: the app chrashes,
4. camera app wont' works since some days,
5. creat a facbookaccount don't work (but restore the account from a backup work for me),

If the problems in the next update be resolved, I'll be happy with my Nexus. :-)
