In a recent work we gave some estimations for exponential sums of the form $∑_{n≤x} Λ(n) exp(2iπ(f(n) + βn))$, where Λ denotes the von Mangoldt function, f a digital function, and β a real parameter. The aim of this work is to show how these results can be used to study the statistical properties of digital functions along prime numbers.
