Samsung Galaxy S2 review


Updated We take another look at the Samsung Galaxy S2 with the upgraded Ice Cream Sandwich software and the latest 4.0.4 upgrade - is it still a stellar phone?

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

Flimsy back cover ; Poor keyboard layout ; Samsung Apps portal

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 S II review


The Samsung Galaxy S II is a serious smartphone. It has everything, at least on paper. But just because a phone comes fitted with the latest version of the Android operating system, a dual core processor and a size of screen you could you could pop on...

Hugely powerful, TouchWiz 4 doesn't spoil the Android experience, lightweight, fantastic display

Not much unless you are really picky

The Samsung Galaxy S II is better than any other Android smartphone to have hit the market so far. It has everything you could want and will need and each of those functions it more or less excels at. It’s fast, it’s bright, it’s clear and, joy of...

The S II is the follow up to Samsung's incredibly popular Galaxy S Android smartphone.

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 S2 review


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...

Beautiful 4.3-inch screen ; Insanely slim and light ; Very fast ; Great camera ; Attractive design ; Endless features and customisation options

Filled with app bloatware ; Menus are confused in places ; Not as user-friendly as HTC and iPhone rivals

Samsung Galaxy S II Review


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

Samsung has pulled out all the stops with the Galaxy S II i9100. It’s squeezed its best-quality 4.3-inch screen, an 8MP camera and a super-fast dual-core processor into a surprisingly slim case. In fa

Samsung Galaxy S 2 hands-on test


The Samsung Galaxy S II reboots one of our favourite Android smart phones with a new screen, dual-core processor and more angular case. Our fingers and toes are crossed that its software is more reliable than that of the Galaxy S.

Powerful Android 2.3 Gingerbread software ; Screen should be brighter and less reflective than that of the Galaxy S ; Kies syncing software will get a welcome refresh

Samsung's widgets may be disappointing

The Samsung Galaxy S II looks sleeker and more powerful than its much-loved predecessor. The screen should blind us with its beauty, and a dual-core processor should keep Android 2.3 Gingerbread running at its sweet-tasting best. We just hope the phone...

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.

Samsung Galaxy S II Review: In Depth


"this is most beautiful phone. Super amoled screen is so bright. Bettery life is so emprobed. Exelent featres, screen is so good. Korean work much much better. I like it very much!"

We think this is the best Android phone yet; all that extra power has made using Android as reliable and as smooth as the iPhone 4. With all that extra power, respectable battery life, and a beautiful screen, it’s perhaps even the best smartphone...
