My AT&T Samsung Galaxy Note 5 has said "No Firmware" everytime I have tried to update it. It has had no Firmware showing since it auto updated to marshmallow 6.0.1. However it shows my Operating System is marshmallow 6.0.1. Please can anybody help? I can't figure out how to download an update to fix this problem. I don't really have access to a computer to connect my phone to, so I really need an "Over The Air" download that is free.
Thank you for your help, I have had this problem since January 2017.
