Sharif Sakr at also gave top marks to the S III's camera, but notes that the HTC One X might be a better choice when it comes to "a much better user interface that sticks more closely to the guiding ethos of Android 4.0." As with previous iterations of the phone, Samsung uses its TouchWiz UI on the S III, and also added some useful features such as swiping contacts to call or message them, and less useful gimmicks like S Voice -- an iPhone 4S Siri look-alike which Sakr said "doesn't work as quickly or as intelligently, and it often cuts you off mid-sentence, thereby wasting time interpreting meaningless fragments of requests."

Pocket-lint's he reviewed. "The huge display, the power, the smooth and fast operation are all to its credit. Add to this the ability to change battery and expand storage and you've a very good package indeed." But he notes that the display could be brighter (the battery-saving feature seems to dim the display a bit too much) and the UI can be a bit cartoony in places.

Gareth Beavis at thought the S III's design is "very sleek and the weight is minimal too -- and battery life borders on the stellar at times." "If the Samsung Galaxy S3 had landed with a premium metallic shell, in the same vein as the HTC One S for instance, any question of design standards would have been obliterated." Overall though, Beavis ranked the S III as "the best smarpthone on the market. It's got every kind of feature we could ask for and more, and raises the bar once again in terms of what consumers should be expecting in terms of battery life, processor speed and media management."

SlashGear's , but said "if your phone has become your multimedia and entertainment hub; if you love a sizable display for gaming, browsing, navigation and multimedia; if you demand high-quality photos and video without bulk; and if you want to future-proof yourself over the typical two-year contract, then the Galaxy S III delivers all that in spades."

In her review on the Galaxy S III, 's Elaine Burke takes a stab at Apple's iPhone ads, saying "it's hard not to be wowed by the speed of the Samsung Galaxy S III, which performs like phones do in advertisements, only this one doesn't need a 'sequence shortened' disclaimer." She also favors the HTC One X for certain tasks, noting that "photo enthusiasts and those who want the best in display are probably best off with the HTC One X, but if your priority is performance, the S III won't steer you wrong."
