It's something to do with hardware acceleration, changing
AndroidManifest.xml (see below) to disable it just for the Sensors Activity
fixes the drawing
<activity android:name=".os.Sensors" android:label="OS/Sensors"
android:hardwareAccelerated="false">
It looks like the hardware accelerated canvas is anti-aliasing the the
drawing of the 3 dials as they are drawn directly onto the Canvas. The
dials are drawn based on a 1-unit by 1-unit rectangle and the canvas is
scaled (before the drawing) by approx 1/3 the screen width (in portrait
orientation)
canvas.scale(148, 148)
on my device.
