Sometimes on Thursday, December 12, 2013 both my Nexus 4 and Nexus 7 received the Android KitKat 4.2.2 update. My colleague’s Nexus 5 received the update on Wednesday, December 11, 2013.
After updating to Android 4.2 KitKat, I tested the tethering and mobile hotspot feature. It is even more broken than before, specifically within T-Mobile USA network. If your Nexus 4 still running Android Jelly Bean 4.3 and you use it as a mobile hotspot, avoid Android KitKat at all cost.
