The two primary outstanding N4 bugs that we've been tracking, and seeing zero progress from Google are
- Nexus 4 stops responding to ARP requests when screen is off with wifi on, and
- Bluetooth kills wifi on the Nexus 4.
We've reported both of these on the CyanogenMod Jira bug tracking site. Let's see if the CM folks can make better progress on them than Google. Actually, if they do *anything* they'll be making better progress than Google, so the bar really isn't set all that high.
We've been favorably impressed with CM 10.1 M2 experimental release, as well as the recent nightly builds, so we're holding out some hope that a more agile, more energized bunch than the Google behemoth can finally get these issues fixed.
