fullscreen in android means: “no bar with the time and stuff at the top, and no nav buttons at the bottom” – it’s known as immersive mode (for movies, games, photos, kiosks, etc…)
In Android 10, the nav buttons at bottom are gone (usually) due to the new gestures based UI. This means status bar is the only thing left. I’m running Android 10, so I never see the nav buttons at the bottom, but I do see the status bar for non-fullscreen (immersive mode) apps.
Using Roon on my phone, I see the top status bar, so Roon can’t possibly be “fullscreen” for me.
so, prior to 1.7.537 we used to round the scale factor to closest 0.25 when scale factor was > 2 – but we dont do that anymore… my guess is that with your scale factor, the tablet gives you a virtual resolution that is too small to display… so either the scale factor needs needs to go down or the screen needs to be bigger.
the galaxy tab s series seem to have an issue where they make the screen “large” by lowering the system DPI, thus reducing the area available for drawing content… that makes it too small for Roon’s UI. Roon tries to go ‘fullscreen’ in these cases to try to squeeze out any extra pixels it can.
my guess is that pre-537 you were rounding down and by luck getting the scale factor to something that fit your screen.
the scale factor is chosen based on system’s DPI settings. there are ways to change it, but my understanding was that this zoom feature on Samsung android was the way to do that… there is another feature called font size - can you try that?
I’m having the developer with the s5e try things now… his s5e with default settings is working fine.
