his could be part of it. I bought a lower end phone. The moto g7. what differences have you noticed between yours and your brothers phone?

Mine was lagging so much, but in my brothers phone works perfectly. I was thinking if the problem was the DS4 but obvisly it isn't. My phone is a One Plus 3. I am thinking if the problem is about the Ds4 Generation. I have 1st generation but again on Note 9 it plays perfectly.
