Thats pretty clueless nonsense by the reviewer, claiming that 25fps would look "a bit jerky", stating that simple as he wrote it.
The jerkiness is indeed visible if you try hard, but its *also* one fps used in big picture cinema, blue ray etc, and that same jerkiness is just the same visible in abovementioned "reference" formats.
Now by all means i would not expect a phone to produce better quality than professional movie gear
