NOT KNOWN FACTS ABOUT SPAM CALLS

somebody online video called me yesterday 8/6/24 from my son's gmail , I thought it was him then I answered, no one was there to answer, I hung up, then texted my son he explained it wasn't him, will that be a means for scammers to get into my phone and acquire my information???? what really should I do?I get spam each and every day, but delete it
