The Good Beautiful 4.3-inch screen; insanely slim and light; very fast; great camera; attractive design; endless features and customisation options.

The Bad Filled with app bloatware; menus are confused in places; not as user-friendly as HTC and iPhone rivals.

The Bottom Line The Samsung Galaxy S2 crams a gorgeous display, lightning-fast processor and powerful camera into one of the slimmest, lightest smart phones we've ever had the pleasure to hold. The Android operating system could be more user-friendly, but it's never felt faster.

There's very little to dislike about the Samsung Galaxy S2. This smart phone is astonishingly fast, with a gorgeous display, a good camera and all the power of the Android 2.3 Gingerbread operating system. And it's somehow all crammed into a case so slim and light that it seems to break the laws of physics.

There's no doubt this is a phone that will impress the geeks in the room. But, if you're not so keen on expressing your geeky side by spending hours tweaking the seven home screens, deleting some of the app bloatware, and customising the millions of options, this phone may be more of a chore than a treat.

It's not cheap, either. Expect to pay around £500 for the SIM-free version. You can also pick it up for free on a £30-per-month contract. Clove and Vodafone provided our review samples.

If your budget doesn't stretch as far as the Galaxy S2, take a peek at the pared-down but still impressive Galaxy Ace .

Note that we've replaced our original review with this one, as Samsung has updated the Galaxy S2's software since the phone's launch. 

Samsung Galaxy S2 vs iPhone 4

Having Android on-board also means that the Galaxy S2 tends to display Google's rather pragmatic approach to user-interface design. Rather than the rounded corners and bright white and grey of the iPhone 4 's interface, Android tends to be dark, wordy and packed with menus. Apps generally sport a mix of on-screen virtual buttons, and plenty more options that appear when you press the menu key beneath the screen.

Android's usability improves with each update -- and there have been plenty since the software arrived on the scene a couple of years ago. But we think Android still has a long way to go before it's a genuine pleasure to use.

Samsung hasn't messed around much with the default Android look and feel. Despite our desire for more user-friendly Android software, we think that's a good thing, because software isn't Samsung's strength.

Of the three sample Galaxy S2 handsets that we tested, one was almost useless due to software bugs, and all of them required us to perform over-the-air software updates right out of the box. The two working models that we tested were generally very stable, but we felt burned by that one bad apple. The original Samsung Galaxy S required several updates before it became really solid, so we were expecting software issues with the S2.

Don't be afraid to insist on a replacement if your Galaxy S2 has bugs like ours did, such as continually resetting the wallpaper to the default option, or refusing to unlock. Also, be sure to check for software updates as soon as you tear your phone from its box.

It's not all bad news concerning the Galaxy S2's software. In fact, moving through the Galaxy S2's screens feels wonderfully whizzy, thanks to the phone's powerful, dual-core processor. Menus pop open without delay, and scrolling is satisfyingly smooth. All the apps we tested also opened with alacrity.

Not having to suffer lag, stutter or hang-ups when opening apps, rattling out text messages or downloading new software makes a world of difference to the overall user experience. Indeed, we struggled to slow the S2 down. Even when we had a bunch of apps running, with more downloading in the background and Flash video playing in the browser, it still felt very fast.

But, compared to the king of touchscreen scrolling smoothness, the iPhone 4, the Galaxy S2 does lack a certain creaminess. Scrolling through long text on Web pages is fast, but the phone doesn't always do a good job of figuring out when you want to quickly flip down, and when you want to reposition the page. That makes it all too easy to move the side of the text off the screen when you merely meant to skip to the next paragraph. It's not a terrible problem on the Galaxy S2, it's just not a perfect situation.

The lock screen also takes just a fraction of a second too long to appear after you wake the phone up, even if you're not using a password.

Lock screen
We were annoyed by the delay in the lock screen appearing, whether we used a security pattern (left) or not (right).

The phone fares better with the two-fingered multi-touch gesture that you use to zoom into photos and Web pages. The zooming is as smooth as silk. It's too bad the Android browser displays a grey and white checked area where it's struggling to render the page, as this looks less classy than the iPhone's system, which manages to throw up what we think is a cached screenshot.

Samsung's added some motion-control features to help you out too. While in the browser, touch the screen with two fingers, and then tilt the phone forwards and back to zoom in and out of Web pages. This feature is slightly too sensitive, and we're not convinced it's easier than just zooming in and out using a pinching gesture, but it's easy to turn off.

In general, we prefer the Android browser on the Galaxy S2 over its Apple rival, for one big reason -- Flash support. Flash videos, menus and games are all visible where they'd just be empty holes on the iPhone.

Searching is easy -- you type into the same address bar where you enter a site's URL, and you also have the option to hit the microphone icon to say your search out loud.

Home screens and widgets

Like most of the latest Android-powered phones, the Galaxy S2 sports a healthy seven home screens, each of which you can stuff full of shortcuts and widgets. The default set-up for these screens, which appears when you first turn on the phone, isn't the most intuitive if you're not already an Android user -- there's just screen after screen of icons and boxes. This can be very confusing if it's your first time entering the wonderful world of widgets, but don't panic. You can set the screens up so that the phone is just as you want it, with a little know-how.

Samsung Galaxy S2 widgets
The amount of information on the various home screens can be confusing if you're not accustomed to widgets.

If you're not sure where to start, you may want to stick with the widgets that are already there until you get used to them. A few of them suggest that you tap them to get started -- for example, the photo-gallery widget will show a slideshow of your favourite shots, but first you need to decide which photos you want to appear in the gallery.

We like to start with a blank slate, though. To remove items from the home screen, simply hold your finger on them for a second, and, when an icon of a bin appears at the bottom of the screen, drag them down into the bin. Many widgets can also be resized in the same way -- hold them down with your finger, and then drag the yellow lines that illustrate how big the widget can be.

Samsung Galaxy S2 Widgets
You can resize some widgets (left), and select more widgets from Samsung's scrolling menu along the bottom of the screen (right).

Samsung has sorted out its own method for adding widgets and shortcuts to the home screen. When you hold your finger on a black area of a home screen, a menu pops up along the bottom from which you can select your choice of widgets, shortcuts and folders, and change the wallpaper. The selection of widgets is shown in a scrolling menu that looks very slick as you swipe through it.

The downside of this fun menu, though, is that you can only see four widgets at once. Once you've installed a lot of apps, which then automatically add their corresponding widgets to the menu, the list of widgets can become pretty long and difficult to move through quickly. We wish we could have more of an overview of what's on offer.

Nevertheless, we like Samsung's method of letting you add items to your home screens from a menu at the bottom, because you can still see the screen clearly enough to help you make up your mind what to add.

The motion-control feature is also employed for home-screen customisation -- hold down an app for a moment, then tilt the phone from side to side to slide through the seven available home screens, and drop the app where you want.

Samsung's changes to Android, such as its widgets (left), tend to be more basic than HTC's (right).

Samsung's own widgets improve with every phone it makes. But Samsung's Android skin, TouchWiz, still doesn't stack up to the best skin in the Android world -- HTC Sense, seen on phones such as the HTC Sensation. HTC has whipped up a customised skin that's more extensive than the ink on a Hells Angel, and its light, curvaceous widgets make Android appear more accessible. Samsung's widgets tend to be more straightforward and squarish. Which you prefer depends on your own taste, but, overall, the Galaxy S2 sticks closer to the basic appearance of Android than its HTC competition.

Samsung Galaxy S2 thumbnails
A pinch gesture shows all your home screens as thumbnails so you can quickly jump to the one you want.

Moving between the Galaxy S2's many home screens is made simple by two quick navigation tricks. You can jump to a specific screen by tapping one of the numbered dots along the bottom of the screen, or you can perform a two-fingered pinch to shrink them all down to thumbnail size, and then tap the one you want to see. We first saw this thumbnail view on HTC phones like the  Desire , and it demonstrates how Samsung makes a habit of reproducing some of its rivals' best ideas on its own phones.

Apps and games

The real Samsung flavouring, however, lies in the app offering. Out of the box, the S2 offers a mix of Samsung's own apps, pre-loaded third-party apps and, on our review sample, Vodafone apps.

The most useful app is the Task Manager, which nimbly solves the problem of monitoring and closing down apps that are running in the background. If you're trying to conserve battery life or keep your phone running at peak speeds, using this app to do some housekeeping now and again will make all the difference.

Polaris Office is another great addition -- it's a suite of apps for creating and editing Word, Excel and PowerPoint documents. It provides a pared-down experience compared to Microsoft's desktop software, but it's slick, intuitive and could prove a life-saver if you need to perform a quick edit on the move.

The Polaris Office app (left) is useful, but the app containing many pre-loaded trial versions of games (right) feels like bloatware.

Samsung's own app store appears on the S2, as well as its music, ebook and gaming hubs, but we think these are mostly worth ignoring in favour of the Android Market and, for example, the Amazon MP3 store.

We'd also get rid of the pre-loaded app that lets you play trial versions of games. Does anyone really want to play a single free round of Who Wants to Be a Millionaire?, only to be told that the trial is over? No way -- especially when mobile gaming hits like Angry Birds are totally free in the Android Market. This gaming bloatware simply clogs up your app menu until you have time to delete it.

Google puts plenty of store in its voice features, but we're not big fans. Things like proper names never seem to work for us, and we always end up resorting to typing. We also tend to use our phone on the go, so shouting at it isn't as practical as stealthy typing. Furthermore, we often don't have the presence of mind to dictate text without repeating ourselves or hesitating.

Google's voice search feature (left) and Vlingo (right) add extensive voice-control features to the phone.

Samsung adds even more vocal tricks to the default Android features by including Vlingo  on the Galaxy S2. The app makes it possible to dictate text messages and emails, open apps and play music. Technically, it's an impressive app, but it can have some unexpected consequences. After accidentally activating its 'driving mode' by tapping a widget, our Galaxy S2 decided to start reading out calendar reminders, letting everyone in the office know that about our yoga lesson. This could be disastrous if you have secret liaisons or embarrassing appointments in your diary, so beware.

Vlingo is a perfect example of the type of software somersaults that are possible on Android. Vlingo is available for the iPhone too, but you can't do the same stuff -- launch text messages, for example -- because Apple doesn't like apps digging down so deep in the OS. Android allows almost any app into its official Market, and doesn't stop you from installing non-Market apps, if you want to.

The Android Market is full of great apps, but the quality can be variable.

The downside of all this app freedom is that you can't always trust Android apps to be of the highest quality. Just one example is the official National Rail app, Train Times. Although we can't fault the S2's ability to run the app smoothly and quickly, the poor design, compared to its iPhone cousin, reminds us why, in some ways, Android is still less crave-worthy than the iPhone software.

Some apps, such as Train Times, don't look as good on Android (left) as on the iPhone (right).

It's not the Galaxy S2's fault that some app designers don't know their way around a user interface. But, if you're thinking of investing big bucks in the Galaxy S2, you need to know how it stacks up against the competition. Apps in the Android Market definitely win when it comes to innovation, but the Apple App Store has a bigger selection and its apps tend to be of better quality.

Notifications

Another place where Samsung's imagination is evident is in the settings shortcuts that sit above the notification bar. Battery life on a smart phone like this one tends to be short, so it's important to be able to turn off features like Wi-Fi and GPS when they're not needed. The battery life of the Galaxy S2 isn't bad -- check out our battery section to read more on this topic. But even so, we love being able to drag down the notification bar from the top of the screen to tap battery-hungry features on and off quickly.

Drag down the top of the screen to get at quick settings shortcuts and all your notifications.

We still see room for improvement here. For example, we'd love to see a screen brightness control too, and it would be handy to be able to open the wireless settings so that we could do things like connect to a new Wi-Fi network. But, for even more control, there's a settings widget that you can stick on your home screen -- it does all this and more.

The notification system on Android phones is so groovy that Apple is essentially reproducing it in the next version of its iOS software, iOS 5. The Galaxy S2 doesn't do anything special with the notification system, but it's really handy to be able to see your unread email, messages, Android Market updates, and other gubbins all in one place, without suffering a barrage of pop-ups, like on the iPhone.

One quirk of notifications is that you only get one chance to hear that you've got a new text message. That means that, if you're out of the room when the message arrives, you have to actually look at the phone to see that someone's been trying to reach you. This can't be changed, so you may want to try the free Handcent SMS app to adjust this setting, along with tonnes more text-message options.

The S2's notification sounds in general are too quiet for our liking, with a gentle bonging for texts and a far too ignorable chiming for calls. Happily, it's a snip to adjust the ringtone and volume in the sound settings menu.

Case and physical design

The Galaxy S2 is a huge phone that grabs your eyeballs and shakes them to attention with its monumental screen and wafer-thin case. It's a miracle of hardware engineering that's only made more stunning by the phone's insane lightness.

God knows what alien technology Samsung has harnessed to make the Galaxy S2 so light, but ignoring the latest trend for hefty metal cases has helped. This means that the S2 has a thin piece of plastic protecting its guts, which may put you off if you prefer the solid feel of the iPhone 4, for example. But the screen on the S2 feels less exposed along the edges than the iPhone 4's, and the fact is that the more flexible plastic case is more likely to survive a short drop than the shatter-tastic iPhone.

The Galaxy S2's plastic case helps to make the phone shockingly light and thin.

The S2 sports minimalist buttons along the bottom of the screen -- a squarish home button, and two touch-sensitive buttons for going backwards and opening the menu. Pressing the menu button for a tad longer launches the search option.

These two buttons light up for a few moments after you press them, but otherwise they're invisible. This makes the S2 look stealthy and cool, but it means that you have to memorise where the buttons are. That's not tough once your muscle memory is used to the S2, but it can be disorientating at first. If it bothers you, dig down into the display settings to turn the lights on for longer, or all the time.
