Don't know what a security update is; just know I'm receiving calls almost daily that I believe are attempts to scan. probably robot, mostly from 888, which I no longer answer, but label as SCAM on my contacts. The list is getting incredibly long. What can I do to stop this?
Samsung didn't release the S20 update until this past weekend, so now the carriers have to put their spin on it! Probably start out to phones in the next couple of days. Updates won't help spam calls. Your carrier may have an app to block them, but they are everywhere!
