Samsung I9100 Galaxy S II

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

Flimsy back cover ; Poor keyboard layout ; Samsung Apps portal

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.

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...

Fast, slim and lightweight; great screen

Unnecessary software

One of the best Android phones available, with a great screen and fast processor

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.

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

1.2GHz dual-core processor ; 4.3in. Super AMOLED Plus screen ; 8-megapixel main camera, 2-megapixel front camera ; Good range of apps ; Fair battery life

Flimsy backplate ; Screen may be too large for those with small hands ; Screen resolution could be higher ; MicroSD card slot is under the battery

The Samsung Galaxy S II is the most advanced smartphone we've seen to date. The large Super AMOLED Plus screen and lightweight build are impressive, and there are some software highlights — notably the ability to create and edit office documents and...

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

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...

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...
