Today's Tech: Hands-on leak dominates Samsung Galaxy S4 build-up, China calls for cyber accord, iOS less secure than Android?

Like it or not, this week is going to be something of a Samsung Galaxy S4 bonanza from a tech perspective, as the South Korean firm prepares to unveil its hotly-anticipated smartphone late on Thursday evening. Of course, ITProPortal will be covering all the happenings across the consumer spectrum and the business sphere, but with so much significance being attributed to the Samsung launch, it would be negligent for us not to give this some due focus. Heading the build-up today we have a full run-down of what to expect from the Samsung Galaxy S4, including all those rumoured features and specs.

But has a Chinese forum gone and spoiled all the anticipation and surprise? That could well be the case, at least if the device that materialises on 14 March matches the handset pictured in today's leaked Galaxy S4 hands-on photos. The images show an as-yet-unseen large-display Samsung smartphone, with a design clearly inherited from the Galaxy S3 - the elongated home button and shiny rear cover in particular speak to the aesthetic make-up of the 2012 mobile. Specifications also correspond closely with what we expect from Samsung's next flagship, so follow the link for your potential first look at the Galaxy S4. Come on, you know it's the sensible thing to do.

China and the US have been trading cyber espionage accusations for quite some time, with each side denying involvement in the digital hacking of the other. Things recently came to a head when American security firm Mandiant released a report tracing a large volume of US-targeted cyber attacks to a Chinese military base. China has vehemently refuted the claims, arguing instead that it has been victimised by hackers working on behalf of the US government. To finally get the security madness under control, Chinese officials have called for international "rules and cooperation" related to the attacks in a bid to clear their country's name. Read on for more details about the latest goings-on in the world of cyber warfare.

When it comes to mobile security, Apple’s iOS is widely regarded to be a safer platform than its rival Android, but a new study suggests this consensus may have to be reconsidered. Mobile application analyst Appthority has published its App Reputation Report for February 2013, and having heavily scrutinised downloads on each software platform, the group claims iOS apps exhibit “more risky behaviours” and are a greater threat to our privacy. Specifically, the study found that iPhone apps typically sent and received more data without encryption, were more likely to share information with third-party ad or analytics groups, and had a greater propensity for accessing areas of your device like your contacts and calendar.
