Samsung Galaxy S2 review

 

Dual-core power, beautiful screen - the Galaxy S II is the kind of sequel we like

Super-fast reaction times ; Slim design ; Ridiculously clear screen ; Clear call quality ; 1080p video recording

Flimsy back cover ; Poor keyboard layout ; Samsung Apps portal

Update: We've updated our review to reflect the software update on the Samsung Galaxy S2 to Android 4.0, Ice Cream Sandwich - and to include the changes found in the recent 4.0.4 update as well.

Samsung Galaxy S2 review

 

Samsung Galaxy S2 Review: The S2 offers an exciting batch of features, from a super repsonsive 4.3-inch touchscreen to a generous 8-megapixel camera

Glorious screen, thin body ; Decent battery performance ; Good camera/video mode

Feels plasticky ; Can't play some Tegra games

Our main complaint about the S2 is the build. It’s doesn’t feel premium and considering it will set you back close to £500 on pre-order, this isn’t good enough.

Samsung Galaxy S2 review

 

Once the best Android handset to own, there are now much better smartphones available for around the same money as a second-hand example

Samsung Galaxy S2 review

 

With attractive Android skinning and a good array of widgets, many of which are resizable, the Samsung Galaxy S II lends itself to plenty of user customisation too.

Nine months might be an eternity in smartphone development, but the Galaxy S II still holds its own very well against more recently released devices. While its price has fallen since its launch, Samsung’s handset is still an expensive option.

Samsung Galaxy S II review

 

The world's slimest smartphone, says Samsung, but does the i9100 back it up with brains?

Fast, powerful, with dazzling design and great battery life, the Galaxy S II is an irresistible Android handset

Samsung Galaxy S2

 

It's Samsung's best smartphone to date, but is it the best in the market?

Vibrant AMOLED display ; Fast processor ; Customised interface works well

Less than perfect built quality ; Mediocre battery life

The Galaxy S should have been a cracking handset and in many ways it is. Its screen is very good, it's fast, it's packed with features, and looks pretty decent as well. Certainly if you're looking for a large and powerful Android smartphone, it's up...

Samsung Galaxy S II

 

A fine phone and worthy champion – but the new kids have upped the ante

Light ; slim ; big screen ; dynamic, colourful video ; new Kies wireless software is neat

Lacks premium feel ; audio can be bettered ; no longer the latest Android OS

Samsung Galaxy S2 review: video performance Internet browsing is fast – the Galaxy S II has a dual-core 1.2GHz chip – and the screen’s size comes in to its own.

The Samsung GALAXY S II should attract huge interest due to its stunning Super AMOLED Plus 4.3-inch (10.9 cm) display as well as the speed of operation offered by a 1.2 GΗz dual core processor. With this device in your hands you feel like you can do...
