Bests & Worsts Reviews from Amazon

Ok, first let me say I am an Android supporter for the better part of 20 years. At first I thought this was a glitch in the Art Program, Clip Studio Paint. But this happened on EVERY program. This is my 2nd attempt at purchasing this Tablet (S7+, 256GB Model) and I had a similar problem with dead space. Clip studio, Art Rage, Art Flow, Krita, AutoDesk Sketch and infinite Painter all have the exact same dead space in the exact same spot. I will be returning this model and ask for a full refund. Hopefully get an explanation as to why this has happened two times now. I am an artist so i have no other reason to use this tablet. Disappointed to say the least. 900 dollars for this.
