I have a small problem. I have a spare smartphone and decided to use it as a screen for my raspberry pi 3B+. I ordered a physical keyboard and mouse for my raspi. But when I connect with my old Smartphone to the raspi through the VNC Viewer app, I cant anymore control the raspi with the keyboard connected to it.
I already tried turning on viewing mode only. But it seems that it only receives touch input from the vnc viewer app.
