5:15 It seems that the ultimate poco icon there was just a placeholder in the dev build. It is there cuz it would come out in the future, but not this update.. u can even notice that both the ultra and ultimate have the exact same icons which supports the fact that it's just a placeholder..
tablet or smartphone? It is mainly because one part of your hand hits another position on the screen. I experience as well. Removing all fingers and touching again helps. Long term if it is a smartphone you can see if you can lock the corner part of the screen. i had to do that at my redmagic phone while playing New State Mobile
