Test results: Screen brightness
By means of a colorimeter we measured the maximum brightness of a white area on the screen of each phone.
As we're used to with Super AMOLED displays, the peak brightness is not one of their strongest points. This is reflected by the test results of the HTC One S and the Samsung Galaxy S3, as both are towards the bottom end of the chart. The One X and the Optimus 4X HD do much better here with their LCD screens. The stand-out phone in this category is Sony's Xperia P, thanks to its extra white subpixels in the WhiteMagic display.
