This always happens when my phone is idle. For example on my desk, my purse, bed, etc. When I grab my phone I’ll sometimes notice on the lock screen there is a cog notification. Every time I unlock my phone to look at it, it just disappears. I have checked my notification log and didn’t see any notifications for settings or anything related to that. Just notifications for other apps that I use. I opened my settings app and same, didn’t see anything. I wanted to know what this means especially since it happens a few times a week.
