Im actually quite confused about this. I have a Samsung Galaxy Luna SM-S120VL, and Straight Talk Wireless is my carrier. I called Samsung one night requesting information about software update availability. They told me they cannot assist me because my device is a TracFone Wirelles service. I contacted Straight Talk Wireless, and they told me Google would push the update. Still curious, I had an online chat with TracFone Wireless, and their response was that the manufacturer (Samsung) would release the update. I'm currently using Android version 6.0.1 and my device has never been updated. So I have no idea what or who to believe. I haven't contacted Google just yet, I'm at the point I don't even know if my phone could ever receive a software update or not. Can somebody please help???
