I have a Nexus 6 that I bought unlocked at Best Buy.
Carrier is AT&T.
Last year, I flashed Android 6 Marshmallow to it because I had never received the OTA. I later updated that to 6.0.1 by loading it myself.
In March, I received the Android Security Patch for March 1, 2016 OTA. I'm not sure what date I received that on but it's been many weeks. I think I got it before March 15. That's the only OTA update / patch that I've received. At least I know that it's capable of receiving OTA updates.
The current Build is MMB29V
I have not received he April 1, 2016 Security Patch OTA.
Do you know if I should have received April's patch by now, April 18? Will it arrive? Will having Mobile Data turned off and running on WiFi affect this?
