I put my 20 on my gear and using the slr app from playstore, its a lil off center but damn its brighter then my s10+
I seen a video on youtube guy takes off that usb connector off so the phone can fit better.
But sadly it has this "drift" using the slr app from the playstore using it cardborad style, sum say if u buy a headset from amazon u can fix that...idk how true this is.
But the 20 does look good, and with a remote i could be fine using that with the slr, deo and gizmo apps from the play store.
