At first I couldn’t locate the “system update” in Settings→System.
Then i have turned on google play services and it appeared – I think it should be noted somewhere that this black box is needed for basic system functionaloty, or it is a bug.
PS. IS this normal if I did not get the latest update yet?
When was the last time you updated your phone system and what version are you on currently? Its normal if you didnt get the newest update yet, it is possible that its not avable with your current network provider due to the update may cause problems with it
