The man, known only as Sylvestre, said his head would have "exploded" - had his mobile took the impact of a bullet.
He was pictured moments after the attacks in Paris still holding onto his Samsung phone which had a smashed screen and huge dent in one side.
Speaking to iTele, he said:
This is the cell phone that took the hit, its what saved me. Otherwise my head would have been blown to bits. I wouldn't wish it on anyone.Sylvestre said he was shot in his foot and was grazed on his ribcage by a bullet.
