Hovering light trail

[ChicagoBullsFan1]

I got my new phone few days ago and I really liked the hovering light on the locked screen ... looks like sunshine... I installed the latest system version and the light disappeared.. I checked if everything is turned on in the settings, and it is turned on on light trail and everything is on but it still doesn't work.. I reinstalled my phone system and it is still missing... could you please tell me how to get it back or delete the last upgrade and put him on he's normal 1st system I had? I really miss that light it looked pretty cool.. please help
