4G rumours

Despite the media going into overdrive with rumours and leaks over the past few weeks, very little is known about the Galaxy S III. Samsung has confirmed it will run the company's new quad-core 1.4GHZ Exynos 4 Quad processor, but that's just about the only confirmed detail so far.

Interestingly, many reports suggest that a 4G LTE variant of the Galaxy S III will utilise a dual-core Qualcomm Snapdragon processor rather than the Exynos 4 Quad. This wouldn't be the first time a smartphone manufacturer has gone along these lines as HTC's One XL does the same. The 4G capable smartphone uses a dual-core processor rather than the quad-core processor utilised in the 3G-capable One X. The One XL is set to launch on Telstra's 4G network in the coming weeks.

A 4.8in HD screen?

Most other speculation has centered around the Galaxy S III's display. The phone is expected to come with a 4.8in Super AMOLED screen with a resolution of at least 1280x720. It is likely to come with either an 8 or 12-megapixel camera and will run the latest Android 4.0 Ice Cream Sandwich software with the newest version of Samsung's TouchWIZ UI overlay on top.

Storage is another widely speculated specification. Recent smartphone trends have seen a move away from removable storage in favour of internal memory. However, most rumours suggest that Samsung will have a microSD card slot and at least 16GB of internal memory. This morning, US mobile phone Web site GSM Arenasuggested the Galaxy S III would come in blue and white colours (the same colours as Samsung's media invitation to the London event), citing an inventory screenshot from UK retailer Carphone Warehouse as evidence.
