What's new in Android 2.3

As expected, today Google announced Android 2.3 Gingerbread and the Nexus S. Android 2.3 is the latest iteration of Google’s popular smartphone platform, and includes a number of immediately apparent graphical changes to the Android 2.2 UI, and a host of under the hood features for developers. Alongside the Android 2.3 announcement came official confirmation of the Nexus S, which appears to be architecturally very similar to the Samsung Galaxy S line of devices, with the notable inclusion of near field communication (NFC) hardware, a curved display, and a front facing camera. 


First up are new user features in Android 2.3, which there are a number of. Most notable among those are a host of UI changes which google claims are aimed at improving both speed, look, feel, and simplicity. The grey shade and notification bar is now solid black, and menu options appear to be either white or green on black. No doubt, this is done intentionally to help Android 2.3 finally leverage power savings of black (off) pixels on devices with AMOLED displays. There are additional changes in the settings application to make navigation easier, though it isn't immediately obvious what those changes are. Gingerbread’s UI brings GPU accelerated animations onboard and will likely provide some speedup to the interface which even with 2.2 was occasionally jittery even on the fastest hardware. 


Gingerbread also brings a multitouch virtual keyboard with repositioned and reshaped keys for better targeting at high speeds. Multi-touch support on Gingerbread enables input such as shift+<letter> and ?123+<symbol>, long-press to select accented characters (which sounds almost identical to iOS's implementation) and of course just general accuracy improvement. Though most of the commercial platforms bundle Swype or a multitouch keyboard rolled by the device OEM (such as the Droid X and Droid 2), it's nice to see stock Android finally getting a better keyboard. 

Along those lines also is improved word selection and one-touch copy-paste support. Press-holding on a word selects for copy and paste, and also enables free-selection mode which brings up handles for selecting much more text, which looks very similar to iOS' copy paste implementation. No trackball or cursor is needed in either selection or cursor mode, which is nice for devices (like the Droid X) which lack a trackball. 


There are also improvements to power management and applications control. It's noted that the system now has the power to manage applications - even closing them if necessary - to ensure maximum battery life. From the screenshots provided, it appears that Gingerbread now provides a graph of charge and elapsed power-on time, as shown above. Note how directly below the graph is a timeline of screen-on events (shown with blue) and charge events (shown with a green highlight). It's nice to see users being given some more direct feedback to manage power consumption. Notably, this UI appears very similar to System Panel, an application I have running on all the Android devices that I come across. 

There's now a link to the manage applications setting window from the options menu on the home screen. No doubt Google views applications manager as the built in task manager for Android (which it basically has been since day one) and wants people to use these tools to manage active applications and see memory footprint instead of third party task managers. 

Gingerbread also adds SIP support for VoIP and internet based calling. Like other SIP supported devices, you need a SIP account and provider of your own, but that's nothing new if you're coming from a SIP-friendly platform.

The big thing Google has added support for is near-field communication (NFC) which enables the device to read information from smart tags and stickers. I'm left thinking that NFC is designed to augment and replace QR codes in the long term. NFC in general has a maximum bit rate of around 424 kbps/s and range of under 0.2 meters, though it's unclear what real-world performance and range will be for NFC tags and readers in smartphones. Expect to see a wave of NFC-enabled devices from RIM, Nokia, and even Apple.

    Why don't you say that Android (stock) still doesn't support proxy configuration for Wi-Fi connections? It's still impossible to use the Wi-Fi network at university etc. Every other mobile OS (my 10-year-old Nokia included) do have proxy support.

    The one I cant understand is still no CDMA option? REALLY? Googles home market is the US, WHY would you limit yourself to T-Mobile. If its really a phone to end all phones, throw in CDMA/GSM and make it a world phone, simple as that.

    I swear, one of the biggest 'noob' mistakes that reviewers pull is leaving Flash 'On' instead of 'On-Demand' in the browser settings and then complaining that it chugs. Let me ask you something... WHY ON EARTH IS IT EVER A GOOD IDEA TO LEAVE FLASH ON. SO YOU CAN WATCH ADVERTISEMENTS. NO YOU LEAVE IT OFF AND IF YOU WANT TO WATCH FLASH-CONTENT YOU TOUCH THE AREA THAT ITS IN. I loaded up your webpage Brain with Flash as 'On-Demand' and it actually panned and scroll just fine without much noticeable lag.

    they're not good at every review, news are slow, everyday there's no new post or news.
    yet they call themselves your source for hardware analysis and news. They just DON'T do review thoroughly.

    Someone pay them to review for all of their article. There must be some script ready or guideline for what they can say. So much hard this days just to find a reviewer which stick soulfully,loyally to their own opinion. If you are so scare of those manufacturer never send product for you to review, F*K them! Use your ads income to buy product to test and also ask from your friend that own computer retailer shop or any of your readers that are in this business to lend u a product for review purpose.

    Just How Hard Could It Be ??????????????????

    darn.. where is the battery life review?

    oh, I'm here for the comment only. The comments are far more sincere and interesting. I still like the old anandtech thou.

    time shift, people change... bye bye anandtech..
