We review the Samsung Galaxy SIII with its rival the iPhone 5, comparing features, specs and performance.

Take a look at the following two articles for more details on each handset.

The Galaxy S3 measures in at 71 x 137 x 8.6mm and 133g. The iPhone 5 is 59 x 124 x 7.6mm and 112g, according to Apple. The Galaxy S3 has a 4.8-inch display, the iPhone 5 has a 4in display. Samsung uses its own Exynos 4 Quad chip for the Galaxy S3 which is unsurprisingly quad-core. It's clocked at 1.4GHz and is based on the ARM Cortex A9 architecture.

As expected the iPhone 5 has an A6 processor which Apple says is twice as fast as the A5 chip found in the iPhone 4S, including graphics performance. Both the Galaxy S3 and the iPhone 5 come with three storage options, 16GB, 32GB and 64GB. Samsung does, however, include a microSD card slot for expansion (up to a further 64GB) which Apple does not. The Galaxy S3 has a rear facing camera rated at 8Mp with the ability to record video in full HD 1080p quality which Apple matches with the iPhone 5's rear iSight camera, although each has different software features. Both front cameras on the smartphones can record HD video at 30fps but the Galaxy S3's has a slightly higher rating at 1.9Mp compared to 1.2Mp.

Apple’s iPhone runs its own iOS software while Samsung’s Galaxy S3 uses Google’s Android 4.0.4 Ice Cream Sandwich and a TouchWiz overlay. Samsung will be updating the S3 to the latest version of Android, 4.1 Jelly Bean while Apple's iPhone 5 comes pre-loaded with iOS 6.
