    PC Magazine reports that Dr. Raymond Soneira of Displaymate Technology Corporation found that upgrading to Android 2.1 will downgrade the quality of images in your image gallery. He tested his theory on a Motorola Droid, where he discovered that Android 2.0.1 uses 24-bit color rendered in 2D, and Android 2.1 uses only 16-bit color rendered in 3D.

    Google claims that this is due to a different company making the new version of gallery. Google, who made the original version, used 24-bit. The new Gallery was developed by Cooliris, also known for their internet image browser. Google didn't really comment on why there was a quality discrepancy, and Cooliris has yet to comment.

    In his original report, Dr. Soneira shuns Google for shoddy display development and suggests that they do away with the 16-bit graphics. He also criticizes the Nexus One's display in general.
    "The Nexus One OLED display has many spectacular qualities, but it is also loaded with lots of rough edges, hasty unfinished beta display drivers and Android software including principal applications like the Browser and Gallery, poorly implemented image processing, poor system integration together with sub-standard factory display calibration. It really looks and behaves like a prototype for a very nice future display, not a finished production display for a world class mobile device that Google markets it to be. It will be interesting to see the degree to which existing units will be corrected and improved with software updates."

    While he's upset with Google's implementation of display software and hardware, he had only good things to say about the Droid's display.

    "In terms of image and picture quality it comes closer to a high quality computer monitor or HDTV than any other mobile display we have tested

    So what? It's just the gallery app. The rest of the OS still runs at 24 bit colour. And theyre planning to upgrade the app anyway. The hero's display only supports (IIRC) 18 bit colour anyway, so it's kinda irrelevant.

    In fact, it's double irrelevant - the gallery reverted to using 16 bit colour because its using the advanced hardware present in the snapdragon processor (thus its much faster and less battery intensive). Dont think the hero has this hardware, so presumably the gallery app on the 2.1 hero will be rendering using the old 2.0.1 method (although actually this may be something to do with APIs and licensing on the older SOCs, might not apply to core OS functions).

    And FYI in android 1.5 everything is running in 16 bit colour, even though the hero's display supports (IIRC) 18 bit colour. 2.1 will actually give us hero users an upgrade, since it can support a colour depth greater than that of the hardware, instead of less than it.

    As for the rest of the post, why would hero users care about the quality of the nexus one's display?
