AC Question
I am using my Nexus 6 since January 2016, with buildup number NBD91P. Whenever some one calls me, we normally get information about caller by his number and name. But since 29th June no information regarding incoming calls are appearing on screen except ring tone, and vibration. It is to be mentioned that it has not received any security update after November 2016, and has not got update after Android 7.0.
