Android 2.3 - Gingerbread

With NFC out of the way, the next major thing which makes the Nexus S special is, of course, Gingerbread. As an aside, what an apt codename for Android 2.3 given its launch just weeks before the holidays. The new version of Android brings a ton of new stuff to the table and smooths over a few rough spots, so let’s dive in.

User Interface - Lots of Contrast

First up is the most obvious change from 2.2 (Froyo) to 2.3 (Gingerbread) - UI changes, a significant change in iconography, and a number of speed improvements. Probably the most striking UI change is how much black there is everywhere, starting with the notifications bar. The background of the notifications bar is completely black, and the cellular connectivity and WiFi connectivity icons change colors.

 

Green indicates an active connection to Google services for syncing your google account, and grey indicates no connection. When you connect to data or change your data connection, there’s a brief transition period when the icons are grey (as expected) due to the loss of connectivity. It’s just a bit confusing at first since the icons never did use to change color. The AM/PM suffix is gone from the current time, and the icons are simplified to be just grey on black. Overall, it’s a vastly more attractive, high contrast look which potentially improves battery life on AMOLED devices.

 

Pulling up the menu on the home screen also reveals some changes. The menu window is transparent like it was with Android 2.2 but given the black treatment the transparency seems more pronounced. There’s also now a shortcut to manage apps in this menu. Virtually all the menus throughout Android have this same white on black style now.

The dialer, launcher, and browser soft buttons at the bottom of the launcher also get some green. Green, orange, and black seem to be Google’s favorite colors for Gingerbread at this point.

 

The other major UI change is what happens when you reach the end of a list and tried to overscroll. Previously, when you scrolled to the end, scrolling just stopped. Now, when you hit the top or bottom of some list and overscroll, you get a glow animation at the top or bottom appropriately. I’m reminded of how plastic fogs as you bend it - keep trying to scroll down and it’ll glow more and more orange.

Gingerbread brings some GPU acceleration to task as well. Although not everything is hardware accelerated, almost all animations are, and there’s a definite difference in feel as a result. Things like the application launcher cube and the corresponding fade-in, fade-out which always felt like they chugged along on the Nexus One are way sped up. Not everything is perfect, however. Scrolling in most lists still sends the CPU to 100%, and the browser still doesn’t feel as smooth as it should, but the UI in Gingerbread does feel faster.

It isn’t really a UI thing, but Gingerbread also includes totally new default notification sounds that are much, much better. The new notification sound is awesome, as are the new ringtones. Previously there was something strangely harsh about all the sounds, the new ones are much more appealing.

Last but not least is the awesome power-off animation. It looks like an old CRT turning off, the contrast of the AMOLED display makes it look believable. Check out our video overview to see it in action.

Applications Manager

The revamped applications manager now shows a bit more information in each pane. For example in the ‘downloaded’ tab, there’s now a bar at the bottom showing how much internal storage is being used and how much remains free. USB storage (which curiously still has a microSD logo) shows how much applications use if they’re on external storage.

  

Every application that can be moved shows up here, and the checkbox corresponds to whether they’ve been moved over to external space.

The dialer also receives a facelift, getting the high-contrast black treatment the same as most of the 2.3 UI. The buttons are more subtle and glow green when touched instead of orange. Notice how everything that used to be rounded is now square - that’s the other subtle UI change throughout Gingerbread.

Keyboard

I’ve been harping on about Android’s stock keyboard since about day one. It’s had a venerable run as the platform’s prime keyboard, but lacked multitouch and never really felt optimal. As a result, virtually every device vendor ships with a multitouch keyboard of their own (like Motorola), or bundles Swype (which is awesome). I think Gingerbread’s keybord is finally awesome enough that we might not need the former of those two. Side by side really says what’s changed best:

 
Nexus S (2.3) stock keyboard, versus Nexus One (2.2.1) stock keyboard

The keyboard takes up less vertical space, there’s more of a margin between keys in the horizontal and vertical direction, and the font is now more readable. Oh, and it’s multitouch. The result is that you can finally do things like shift+<character> or hold down a key for accented characters and simply slide your finger over.

The spacebar now glows orange when Android predicts that one word best fits from the characters you’ve typed. Pressing space inserts that word, and a space, whereas before it was never really clear what you could do.

Overall usability with the new stock Android keyboard is much improved. I can finally type at full speed and use multitouch combos, but the real improvement comes from the subtle change in shape. Though  vendors will still probably stick swype on retail devices, the multitouch keyboard in Gingerbread honestly eliminates the need to do much more.

There are also new selection aides for both going back to a word suggestion or replacement, and selecting text to copy and paste with. Tap on a word, and you get the selection icon.

You can drag that around to select words which are then underlined appropriately. If you long press and tap select word, you’ll get two selection handles which can be dragged around to highlight text. 

Tap again and you’ll get a dialog to cut, copy, or paste. It’s definitely an improvement. This selection workflow doesn’t require a trackball anymore, which is undoubtedly a contributing reason for why the Nexus S lacks one.

There’s a bit of a rough spot when selecting text from an email, which is a bit of a puzzle. The workflow curiously still involves having to hit menu, more, select text, and then drawing a line across text you want highlighted. What’s odd is that between selecting text and drawing that line, Android literally draws a mouse cursor in the window. I’m not sure what that’s doing there, but it puzzles.

 

You do get the same selection handles though, which works perfectly. Tapping on the text in a non-editable field simply copies it to the clipboard instantly.

SIP calling Support

Chances are that most people don’t know what Session Initiation Protocol (SIP) is. I used SIP briefly a long time ago and had to refresh myself even, but SIP essentially is a protocol for setting up voice and media streams between devices. For most intents and purposes, that boils down to VoIP, which is what’s done with Gingerbread. The idea is to get a SIP account from a provider which will route calls to PSTN callers, and serve as a gateway for other SIP account holders to call you. With a SIP account, you basically get an internet phone number, and the ability to call normal PSTN numbers for a small fee.

I set myself up with a simple account from voip.ms and configured the Android client to use it. SIP account settings are inside call settings, at the bottom under ‘internet call settings.’ You can choose whether to send all calls over your SIP number, ask each time, or only do it when calling other SIP accounts.

  

Inside settings you can configure whether or not you want to have an active registration for receiving incoming calls. Of course, keeping that open uses some battery life. Inside the SIP account settings are fields for your credentials, server, and basic configuration. There isn’t any choice about what codec you’re going to use.

 

With this enabled, when you go to make a call (if you so chose) you’ll be prompted whether you want to connect over cellular telephony or through VoIP. The disappointing part is that VoIP calling only works over WiFi. Yeah, that’s a completely arbitrary limitation.

 

It’s a disappointment that we’re back to playing this game appeasing carriers by putting arbitrary limitations on features. Nokia doesn’t do it on their devices, and yet European carriers haven’t bled themselves to death. I’m sure this limitation will be gone within 10 minutes of someone rooting Android 2.3 on the Nexus S, so why bother?

Overlooking the limitations, SIP calling works, and works just fine. It’s integrated into the Android platform natively, just like it should be. Calls come in and go out just like they would if you were calling through cellular voice. I thought voice quality was fine, and people I called said I sounded fine as well. Of course, a lot of that depends on your SIP provider and what routes they have for PSTN, so your mileage may vary. One thing I did notice is that SIP on speakerphone is way, way too quiet, more on that later.

Battery Manager

Probably my favorite change is how much improved the battery use window is. I thought Android previously had a very useful breakdown of battery use based on total consumed CPU time and metrics like how long you’ve had the screen on, but the new graph is even better. From battery use, there’s a graph at the top. Tapping on it brings up a much larger graphical view of consumption.

 

The line corresponds to battery charge. Below it are timelines for signal, GPS, WiFi, screen and device activity. At the very bottom is charging. The result is that you can see how different activities affect the battery, and what uses more charge based on the slope of the line. This is something I’ve done previously with System Panel which shows similar information, but lacks phone signal, GPS, and WiFi tracking.

There’s the total running time for the plot on the x axis, and the total time the phone has been on battery along the top. Every platform needs something like this.

Other Changes

There’s a subtle tweak to the downloads manager, but nothing major, and the stock camera now has a few more features. I’ll discuss the camera changes in the camera section. The rest of the changes are under the hood so to speak. There are updated OpenGL ES drivers which provide more efficiency and faster 3D performance, a concurrent garbage collector for the Dalvik VM which now only takes 3 ms, a kernel update, Khronos OpenSL ES and Khronos EGL support, and a host of new sensor support. The Nexus S notably includes a gyro, and the Android 2.3 stack now includes support for a ton more sensors, including barometer. There’s also native support for front-facing camera, which I’ll show in the camera section.

Android 2.3 also supposedly adds WebM and VP8 support, though I’ve had no success playing back any test videos and am working on encoding some smaller ones to try on the Nexus S. One video played back using the android video player had audio but had no video, other videos played back in the browser showed controls but never started playback.

 

The other new thing is support for devices with no external storage. Instead, internal storage can be partitioned to work like a virtual SD card. In the Nexus S, there’s 16 GB of iNAND, which is SanDisk’s combination of MLC NAND, a NAND controller, and DRAM on a single die, all of which expose themselves over eMMC or eSD. SanDisk’s documentation notes 12 MB/s and 30 MB/s sequential writes and reads, respectively, though there’s no information about how small size reads and writes fare. In essence, iNAND is an embedded storage solution. On the Nexus S, 1 GB is partitoned to act like traditional “internal storage,” and 15 GB are partitioned as “USB Storage” which in principle acts just like external storage used to.

Overall Gingerbread brings a lot of notable improvements, the majority of which are pretty much immediately obvious. New keyboard, a tweaked graphical style, better copy and paste, better power and applications management tools, SIP VoIP calling natively, NFC compatibility, support for devices with extra large screens such as tablets, and interestingly EVDO Rev B support in the telephony manager. If you’re interested in all the changes, check out the official Android SDK 2.3 platform notes (http://developer.android.com/sdk/android-2.3.html). That said, there are still a few things I wish Gingerbread included.

There are a few places in the UI where the old silver-colored UI shines through that could’ve benefited from some of the new black/contrasty goodness. The address bar in the browser and the messaging application both have lots of chrome instead of black. It’s also a bit puzzling why there isn’t any new first-party support for video chat given the front facing camera. Google could have leveraged its already-popular chat infrastructure (Google Talk) to provide a seamless video chat experience across mobile and desktop. Instead, there’s really nothing to do with the front facing camera other than take pictures of yourself or use a marketplace solution to video chat, all of which I’ve enjoyed marginal at best success with.

Small Fixes

There are a few other changes that I consider fixes which Android 2.3 has that aren’t directly noted. Chief among them are working 802.11x EAP support, which I can confirm works perfectly. I tested on an enterprise-level 802.11x network which uses PEAP with certs and had no problems authenticating, staying online, and even handing off.

The other notable thing I tested was to find out whether the messaging (SMS/MMS) database is any better. In Android 2.1 and 2.2, I found over and over again that the whole thing would slow down after getting a day or more worth of texts inside. For me, that translates to a couple hundred. To test, I sent myself 200 messages and had friends bombard me best they could with everything they could muster. All total just over 500 in under an hour. The messaging application remained speedy and hasn’t become unbearably slow like I’m used to saying. As best I can tell, this seems way improved if not entirely fixed.

Finally here's a video I put together with all the changes and a comparison with the Nexus One loading the AnandTech homepage:

    I agree I have a nokia and the phone jack is on the top side. I have wished many times that it is on the bottom Reply

    I also miss the trackball on my Galaxy S.

    But I now use Swiftkey , a pretty good keyboard, and it also have arrow keys (press "123" then symbols : {&= key) to see it.

    Basically a Galaxy S (which was basically a Nexus One with a better screen and faster GPU), with a few extra features, unlike the Nexus One which was pretty revolutionary for its time.

    Of course, the Nexus One isn't even a year old, which isn't such a long time.. but sometimes it feels like the N1 was released in another decade considering how fast things have moved. I hope the Nexus 3 or whatever at least as a dual-core out-of-order CPU and other improvements.

    Well I purchased my Nexus S, and am very pleased with the phone. Scrolling is not as smooth as I was lead to believe, but still glad I purchased one. Reply

    Brian, are you sure on the 3G radio.
    The T-mobile Samsung Vibrant radio, although not advertised, is at least Quad band
    It has the 1900 radio on by default for 3G on AT&T.
    You can also turn on the 850 band in the service menu although it's not confirmed to work in 850 mhz only areas of AT&T coverage.

    >Don't you usually have your phone in your pocket upside down anyway?

    Not if it's in the shirt pocket. Or jacket inner pocket. Or on a belt holster.

    I'm a lot more likely to use a headphone with the phone in these places rather than in my pants pockets, where walking, sitting or standing up is more liable to crush/damage the headphone jack.

    A new on-screen keyboard for Android from Keypurr has directional keys, and it is in the main screen (no need to flip to another screen). I am using Keypurr on my Galaxy S - and love it!

    In addition, it has large keys (almost twice as large as the standard keyboard) and very clever and up-to-date dictionary. I can type on it as fast as hardware keyboard, or type one handed. It also comes in black or white skins, has function keys, and more. I think Keypurr has some good short videos on their site: www.keypurr.com

    Keypurr is a new Android keyboard that uses a full QWERTY layout with keys that are are almost twice the size of other onscreen QWERTY keyboards. It also has a dictionary that includes abbreviations, acronyms, and words borrowed from other languages. Best of all for Nexus S users (and anyone who's phone doesn't have a trackpad) it includes customizable function keys that can be used as directional controls.

    Keypurr allows users to type with greater speed, confidence, and ease, than any Android keyboard! Check out our website: www.keypurr.com or our youtube channel: www.youtube.com/keypurrtech to learn more.

    "... people want carriers to provide first-party support for devices, and people want to play with devices in stores before making the jump ..."

    I wouldn't consider a carrier as the first party when it comes to providing support for phones (there is no doubt that they are the first party when it comes to network issues). As it stands, carriers are only worsening the experience by slapping on unwanted customizations and hindering roll-outs of OS updates.

    What is stopping you from "playing with devices" in a retail store (either by manufacturer/OS vendor/authorized reseller)?

    IMO the real reason for the prevalence of "carrier subsidies" seems to be consumers preferring to pay by installment, or simply unaware of the fact that they end up paying more in the end.

    I'm always disappointed to find that no reviewers mention the fact that Android doesn't support WiFi proxy 'out of the box' - any suggested solutions to this lack of functionality require that the user 'root' their device, which is not necessarily acceptable to everyone (for all sorts of reasons).

    This lack of functionality precludes student usage on campus, and crucially (in my opinion) any corporate in-house 'managed' usage, where any WiFI authentication is a pre-requisite.

    As a CIO, I'm forced to eliminate Android-based devices from consideration as a corporate standard, and constrain my options to Apple, Microsoft and (hopefully) any upcoming HP WebOS-based devices.

    This is deeply disappointing to me personally, as I applaud any attempt to separate the OS from the hardware, liberating hardware manufacturers to compete and innovate, and thus giving us, the end users, ever expanding and increasing capabilities in a portable device. I had high hopes for the relatively open Android environment in this regard.

    I would also refer you to this (somewhat emotive) link that outlines the issue in more detail:

    Thank you, Anandtech, for what is otherwise superb technical journalism.
