Adding to the mountain sized pile of Samsung Galaxy S3 rumours, speculation now suggests the device will be just 7mm thick upon release.

According to GSM Arena Samsung is aiming to reduce the, currently unconfirmed, S3 to the same minuscule levels as Motorola's current Razr, which measures in at a piddly 7.1mm thick.

Unfortunately, GSM Arena also suggested that the device would house the same bumped design as the S2 - meaning it could presumably be thicker than 7mm at its thickest point.

As well as speculating about the device's thickness GSM Arena also lent credence to the ongoing theory that the device will feature LTE support - a fancy word for 4G.

GSM Arena's report is the latest in a long line of unconfirmed claims regarding Samsung's next flagship device. Prior to it, Apple rumour mill Tip Today's iPhone issued a report claiming a trustworthy unnamed source - please take with a pinch of salt - had confirmed that Samsung and Apple's next flagship devices would be waterproof.

Specifically, Tip Today's iPhone suggested that the two devices will feature a special nanocoating over their chips, protecting the components from water damage as well as the usual day-to-day wear and tear.

The tech will reportedly be made by Liquipel - a company that already offers to retroactively coat smartphones with the nanotech. "[B]oth [ the Galaxy S3 and iPhone 5] will have had liquipel treatment as they'll be altering the wording on insurance," Tip Today's iPhone quoted the unnamed source as saying.

Previously, a slew of news outlets had issued reports suggesting the device would house an improved battery capable of lasting at least a day, even with heavy use.

Unfortunately for those looking forward to getting their hands on the two devices, Tip Today's iPhone's source made no mention of the smartphone's release dates. That said, despite the lack of official word from Apple or Samsung analysts have issued there own theories regarding when consumers can expect to see the devices.

Regarding the S3, the most recent estimate stemmed from industry insider Eldar Murtazin, who pegged the device with an April, 2012 release date. Eldar Murtazin issued his theory earlier in January, when he tweeted: "@AllAboutSamsung btw april ss [sic] far as I know," when asked about the device's release date.

Eldar Murtazin, though far from an official information source, has a good track record for calling key industry dates. Already he's had several predictions regarding the fate of Blackberry maker RIM, which have turned out to be correct. Murtazin's comments follow a slew of rumours regarding Samsung's follow up to its popular Galaxy S2.

None of this has been confirmed by Samsung.
