Steps to reproduce the problem:
1. In desktop mode launch an Android app relying on DPI (provided by DisplayMetrics)
2. switch to tablet mode
3. rotate screen

What is the expected behavior?
The DPI are stable among tablet/desktop mode and rotation.
xdpi=234.46153
ydpi=234.9133

What went wrong?
The DPI value is not stable and broken.
xdpi=156.3077
ydpi=352.36993

Did this work before? Yes ChromeOS 69

You can visualize the problem with this simple Android View:

```
    @Override
    protected void onDraw(Canvas canvas) {
        DisplayMetrics dm = getResources().getDisplayMetrics();
        float widthInches = dm.widthPixels / dm.xdpi;
        float heightInches = dm.heightPixels / dm.ydpi;
        float widthCentimeters = widthInches * 2.54f;
        float heightCentimeters = heightInches * 2.54f;
        float widthOneCentimeterInPixels = dm.widthPixels / widthCentimeters;
        float heightOneCentimeterInPixels = dm.heightPixels / heightCentimeters;
        Paint paint = new Paint();
        paint.setColor(Color.BLACK);

        canvas.drawColor(Color.WHITE);
        canvas.drawLine(100f, 100f, 100f + widthOneCentimeterInPixels, 100f, paint);
        canvas.drawLine(100f, 100f, 100f, 100f + heightOneCentimeterInPixels, paint);
    }
```
