It seems the Samsung Galaxy S4 has been rooted, and it's not even out yet. Android tinkerers claim to have worked out how to open up the new smart phone's software to add new features -- but not the quad-core version we're getting in the UK.
Rootin' tootin' Android experts at XDA have published the necessary files for rooting the S4, and a guide to talk you through the process of unlocking its hidden powers -- but it only works with the Exynos 5 Octa eight-core version of Samsung's new flagship phone.
That won't be much use to anyone who gets their hands on the quad-core model destined for Britain, the US, and other countries around the world. Over here we're getting the S4 with a four-core Qualcomm Snapdragon 600 processor instead, reportedly due to shortages of the new Exynos chip.
No doubt a method for rooting the quad-core model is on the way, so if you want to open up your phone I doubt you'll have long to wait after it hits shops. To learn more about rooting, check out our guide to rooting the Galaxy S3, and our top five ROMs for it.
The S4 goes on sale on 26 April, available from all the major networks and retailers. Prices are yet to be confirmed, but early indications suggest it could be cheaper than its fiercest rival, the iPhone.
