[Sprint Samsung Galaxy S7 Edge Guides, News, & Disc] jtash01:
I am not sure which one. I had done a lot of loading and rebooting iterations to get the service to keep working. But what I have attached below is a list of all of the Samsung specific packages that are retained in my rooted and debloated U firmware. I obtained this list from my rooted U QG1 firmware using Titanium Backup and then selecting from the list only packages that are Samsung specific. So I would compare this list with the Samsung packages that you have inactivated or removed to find the culprit. As I said, I have had no problems losing Samsung account connectivity after rooting with these packages ACTIVE. I have no frozen apps as they have been debloated instead.

The values in parentheses are the package name for the apk on the same line.
