I have been reading this forum for well over a year and took the plunge into trying the Android L preview on my Nexus 5 32 GB. I am loving the way the software functions on my nexus 5 except i am having one issue. The phone i installed it on is a secoundary phone i have connected with sprint. When i am using the phone for a phone call and i get an incoming call I do not see who is calling and the phone doesn't show who is calling. Any ideas?
