Vlad Savov, The Verge:
The contraction to a 4.7-inch screen size is a total boon for the Galaxy Alphaâ€™s usability, but its display isnâ€™t all good news. Iâ€™m not worried about the 720p resolution, which is perfectly adequate at this size. The viewing angles are also not a problem, as youâ€™d expect from an AMOLED display, plus the Galaxy Alpha is among the most readable phones Iâ€™ve used outdoors. It outdoes both the Sony Xperia Z3 and Z3 Compact in those performance measurements, but it collapses when it comes to color accuracy. That old familiar blue-green tinge that was the bane of earlier AMOLED displays has returned, and even though the Alphaâ€™s screen uses the same Diamond Pentile subpixel arrangement as on its more senior Galaxy Note and Galaxy S brethren, itâ€™s noticeably worse. The background of the Twitter Android app is supposed to be white instead of baby blue, right?
[…] Samsung offers a variety of screen color modes, but none of them neutralize the bluish shift in tone. Itâ€™s not an absolute tragedy, and itâ€™s something I didnâ€™t immediately notice in my first time using the Galaxy Alpha, but this kind of improper color reproduction starts to wear on you over time. Particularly if thereâ€™s someone nearby with a true high-quality display on their phone. Itâ€™s disappointing to see Samsung trip up on the display front, which is at least as important, if not more, as the physical design of the handset.
Weird; perhaps a different team was responsible for this particular OLED display used in the Galaxy Alpha? The Samsung Galaxy Note 4 was just awarded the best smartphone display by Raymond Soneira.
