system update icon gone

[PFOURIE]

After updating app's I notices that the"system update icon" is gone, how do I get it back, I've tried restarting, but no app

The icon appears only when an app or system requires an update. If it's gone you are up to date.
Check
Settings/about device/software updates.

I don't have an app called "update".  Are you sure it's a preinstalled Sony/ Google app?  Do you have any more details about it.
