Tonight's results on The X Factor 2016 have been hit by a MAJOR technical hitch.
It was Girl Band v Boy Band on the show last night as the remaining eight contestants performed live for the third time this year.
Those left in the contest going into the weekend were Nicole Scherzinger's Boys - Matt Terry and Ryan Lawrie, Simon Cowell's Girls - Emily Middlemas and Samantha Lavery, Sharon Osbourne's Overs - Honey G and Saara Aalto, and finally Louis Walsh's Groups - 5 After Midnight and Four of Diamonds.
The judges had plenty to say on each of the latest performances but as ever it was viewer votes alone that determined the bottom three this evening.
In this evening's live show on ITV, Dermot O'Leary announced the trio of acts in the danger zone.
Samantha Lavery, Saara Aalto and Four Of Diamonds were in the bottom three.
The trio then faced the new twist with a second round of voting in the life line vote.
Fans had just 5 minutes to vote to save one of the bottom three in a free poll on the official X Factor app.
However many found the app just didn't work.
Twitter was full of complaints as the official app on at least Apple's iOS software reported problems.
While some people manage to vote, others found that that the life line vote was closed before the problem was resolved.
"'The lifeline vote is now closed' It was never open for me! @TheXFactor #XFactor," wrote one fan.
There was no mention of any problems in the live show, as host Dermot O'Leary announced that Sam had topped the poll.
As a result, Four Of Diamonds and Saara went on to the sing-off.
The X Factor 2016 continues next Saturday and Sunday night on ITV at 8PM.
