In this paper, we consider the AdS–Schwarzschild black hole in light-cone coordinates which exhibits non-relativistic z=2 Schrodinger symmetry. Then, we use the AdS/CFT correspondence to investigate the effect of finite-coupling corrections to two important properties of the strange metals which are the Ohmic resistivity and the inverse Hall angle. It is shown that the Ohmic resistivity and inverse Hall angle are linearly and quadratically temperature dependent in the case of corrections, respectively, while in the case of Gauss–Bonnet gravity, we find that the inverse Hall angle is quadratically temperature dependent and the Ohmic conductivity can never be linearly temperature dependent.
