Please explain what it is about "his method" that "appears highly questionable"?
Dr. Soneira indicated that he will publish in the second article (of three) the measurements for: color temperature and chromaticity, color gamut, intensity scale and gamma, brightness decrease with viewing angle, black level and contrast ratio shift with viewing angle, color shift with viewing angle, RGB display power consumption, OLED and LCD spectra. Are you saying that you anticipate the way these are achieved, or the measurements themselves are questionable?
In this first article, he discussed the measurements (for peak brightness, black-level brightness, contrast ratio, screen reflectance, high ambient light contrast rating, dynamic color and dynamic contrast, color depth and granularity, and display image) after generating the analytical test patterns with a spectroradiometer and measuring "in a perfectly dark lab to avoid light contamination with devices' backlight set for maximum brightness with the automatic brightness light sensor control turned off, and running on their AC power adapter with a fully charged battery, so that the battery performance and state was not a factor in the results." Was it something about this method that is questionable or lacks competence?

This makes it kind of hard to conclude which display is best, just which total package is best.
However, Dr. Soneira stated up front that the "in-depth measurements and analysis were for the OLED and LCD displays on the Google Nexus One and the Apple iPhone 3GS
", not the display technologies themselves. He said, "the inner details of the display technologies are very interesting, but our concern here is to evaluate the actual image and picture quality that they deliver
." Do his methods not support his objectives?
He further stated that, "some of this is undoubtedly due to poor integration of the display hardware with the Android OS and software. Much of it, however, is simply due to very poor factory calibration and quality control." Was it this assertion you find incompetent?
Please explain, as your point about scientific testing competence is unclear to me. What would the "competent scientific test" consist of?
