We study the relation between semi and fully device independent protocols. Our work leads to new random number generating protocols with higher rates for both scenarios. As a tool we use the correspondence between Bell inequalities and dimension witnesses. We present a method for converting the former into the later and vice versa. As a byproduct we obtain whole new classes of inequalities and witnesses. Finally, we show how optimization methods used in the studies of Bell inequalities can be adopted for dimension witnesses.
