That's good to hear and thanks for letting us know. I couldn't test it out. I already stopped the notification by way of factory reset. I never knew this notification option was in there. Found it this morning.
Let everyone know if this stops it permanently.
Try opening the find my mobile app. Turn it off. Select the 3 vertical dots in the upper right hand corner of the page. Select notification. Turn off the category New features. I don't know if this will stop them but it might be worth a shot.
IT WORKED FOR ME!! finally! Thank you it was driving me insane, I thought it was just me!
Now I want to get rid of the software update "silent" notification that is always there and pops up as a whole screen once or twice a day
On my S9, I found the mobile app., selected the 3 vertical dots in the upper right hand corner of the page. Select notification. Turn off the category New features. Now silent.
