Since the Samsung Galaxy S Advance (I9070) was upgraded to Android 4.1.2 Jellybean, many clients updated their phones. Others also went ahead and rooted their devices so that the warranty is reinstated since rooting a device deems the warrant void. With time though, users may want to return to stock which means they’d have to unroot the device.
