Sam was eliminated from the competition on Sunday evening (17 November) after falling into the bottom two alongside Luke Friend. Both boys were members of Louis Walsh's team.
Essex-born Sam had been on the receiving end of some tough criticism over the weeks so it can't have been easy for him preparing to sing for survival against Luke.
But chatting on ITV's This Morning earlier today, he said: "Not at all [was I defeated]. There hasn't been a point where I got on that stage and thought I was defeated at all... I had that negativity from day one and I managed to get to week six so I was kind of proving it all wrong."
Sam's survival song earned him the highest praise from the judges yet. Nicole Scherzinger even threw a pen at him before questioning why he'd saved his best until it was too late.
He explained today that he felt more comfortable performing his survival song - 'Iris' by the Goo Goo Dolls - than he had other tracks in other weeks as he had full say over the survival song. "I think that's the sort of music I like and 100% of the save me song is your choice, with the rest you have to find middle ground with the judge, music team, please the public, everyone else on the show..."
As for coping with criticism each week, he said: "I think it's a mind thing about staying positive. I think you have to see the positive in everything. If anyone gives me criticism I can build on and make myself better from then I'll take it on board, but if it's just negative I'll let it bounce off me."
This week's X Factor had a Great British Songbook theme. The guest performers on the results show were Miley Cyrus and judge Gary Barlow.
X Factor continues Saturday on ITV.
