The series ten winner was appearing on ITV's Good Morning Britain today, just two days before she'll hand over her X Factor crown to Fleur East, Ben Haenow or Andrea Faustini.
Asked for her advice for the finalists, she replied: "Slip a phone somewhere where it can be hidden because you'll need it!
"Get as many photos of everything and savour every bit of it. I didn't do that last year. There were so many opportunities to have photos taken with famous people and I didn't have my phone on me."
Sam, 37, continued: "It is such a blur. The whole final experience, you forget everything. I don't remember anything except Sharon being on her knees."
Fleur, Ben and Andrea will battle it out on the X Factor series eleven finale across Saturday and Sunday night, with will also see guest performances from the likes of One Direction and Take That.
Diplomatic Sam refused to reveal who she thought would win the show - particularly as Fleur, Ben and Andrea were all watching her interview! - but did admit she'd been completely blown away by Fleur's performance last weekend.
