Can’t adjust DSP settings on Android

Unable to adjust dsp settings on Android… Anyone else have this issue?

Oneplus6t running latest android

I believe at the moment you can only turn DSP on or off via Android. No adjustment.

So too adjust, could you do this remotely via another device?

I use an Android phone - LG V30, 6" screen - which is as per Wayne’s comment. I can adjust DSP via my 8" Android tablet though. I think it’s to do with available screen size, which makes sense.
