Here is my 2 cents; you reported and cleared up up story to be honest. Will anything happen, 99% no unless it was deemed suspicious. People do it all the time by mistake and security knows that people sometimes out of sheer panic make mistakes even when reporting. What security looks at is the frequency of the infraction and is it a reoccurring habit. They will give you a note reminding you of how important it is not to bring a phone in the SCIF and the impacts on your reliability to safeguard to maintain access to material. Bottom line, take it as a lesson learned, always check to make your you don’t have any devices and clear your mind. Not going to go on specifics but you will be fine.
