Thank you, PJRed! It never did go away on my Samsung GS3; I had to 'Force Stop' it and dump cache everyday, which got a bit old. Bought the GS3 in 2012 and after 5 years.... it's still running ICS 4.0.1 ! I wonder if there's any other Galaxy phones still running the 2012 Ice Cream Sandwich ?! :>D
But the motherboard? or processor? or something? ---with constant shutdowns no matter the battery %--- finally started going out this May/June, hence the upgrade to the S7A, which I'm liking a lot, so would like to keep it at Marshmallow 6.0.1, indefinitely, until I choose to allow the 7 upgrade.
The upgrade that's been trying to download (since yesterday) is:
' AT&T Software Update - v2.2.37 '
