The visual aids the GALAXY Note II can provide out on the training ground allows O'Shea and his team of coaches to easily explain what they expect from the players, visually explaining where they are going wrong, and what needs to be improved.
"It's very difficult to say 'you have to do this', especially as we don't have one way of doing it, but potentially the Note II could do this, and make everything we do better."
O'Shea concludes: "As a tool the GALAXY Note II will be a massive, massive benefit and we want our coaches and players to be on top, and will I might be IT illiterate I know the benefit of this for the team in terms of our performance and this is why we're massively into it."
Players have a play
Although mainly used by the coaching staff at the moment, a few key players in the Harlequins team are also reaping the rewards the Samsung GALAXY Note II has to offer.
We spoke to Quins' second row George Robson, who had recently returned from a tour with England, to find out how the GALAXY Note II was helping him discuss tactics with teammates and keep everyone up to date on the next opposition.
"Because of the position I play in the team I make a lot of the calls during the match, most of which are based on analysis done prior to the game," explained Robson.
"I get all my analysis and match previews sent over each week via Dropbox, which works really well with the GALAXY Note II.
"It's easy to use, really clear and means I don't need to be at home in front of the laptop to see all the latest news and watch the insight videos.
"The S Pen is also really good, especially when I'm talking to the other guys about tactics I can highlight certain aspects and the large screen makes it really easy to draw, while still being small enough to carry around.
"It's also the best thing I've used for recognising my writing. I've struggled to write on other devices, but the GALAXY Note II picks up my handwriting really well."
Overall, while the GALAXY Note II's integration with the teams' tactics and training may still be in its infancy, it's clear that Harlequins can already see the potential Samsung's smartphone can provide, with real benefits coming to the fore after just couple of months' use.
