I have the chance to buy a pair of D2s to go with the s4 mk3 i have, but reading i hear the screens dont work correctly on d2's when paired with s4, is this still an onging problem?
Yes. They are lagging on D2 and it is a bit distracting.
Thank you, how bad is it, is it not worth the hassle?
I would not recommend using both at the same time. But the D2's by themselves are awesome.
