Draw circle or arc around edge of round device

Is there a good way to draw a circle around the edge of a round device?  I'm working with a fenix 5X and my circle almost completely disappears in the lower right corner.  If I increase the pen width, it's less noticeable, but you can still see the circle is slightly thinner in the lower right.  Here's a screenshot (I'm trying to draw a red circle):

Here's my draw code:

var screenWidth = dc.getWidth();
var screenHeight = dc.getHeight();
var centerX = screenWidth / 2;
var centerY = screenHeight / 2;
dc.setColor(Graphics.COLOR_RED, Graphics.COLOR_TRANSPARENT);
dc.setPenWidth(1);
dc.drawCircle(centerX, centerY, centerX);
