The cloud storage competition on mobile devices is heating up, as Box goes on the offense against other established players in the market. The cloud storage company has struck a deal with Qualcomm, one of biggest SoC makers in the Android ecosystem, as well as with Microsoft for its Windows Phone devices. We figure you’ll be more interested in the former, so here are the deets.

The Qualcomm partnership means that select devices powered by Snapdragon processors will come preloaded with the Box Android app. The main perk for users is that they will get 50GB of free Box storage. The deal doesn’t necessarily mean that the Box service is mandatory, but phone manufacturers will be given the opportunity to opt in on the offer.

Qualcomm’s Snapdragon processors are prominently featured in recent top offerings from major Android manufacturers. The North American variant of the Samsung Galaxy S3 and the HTC One X, for example, are powered by Qualcomm’s Snapdragon S4 chip. Both Samsung and HTC, interestingly, have already inked deals of their own with Box’s rival Dropbox. Sony Mobile, on the other hand, has taken Box’s side — the Xperia Ion LTE comes with a free 50GB Box storage.

According to the company, the Box Android application has been downloaded 2.2 million times since it was made available back in September 2010. With Qualcomm on its side, the annual number of downloads is expected to triple.
