Sony has not been very active, when it comes to releasing updates for its existing devices. The company has acknowledged this on its blog and notes, "Thank you for all the feedback on our Jelly Bean 4.1 rollout for Xperia 2012 products - we're aware the process hasn't been as succinct or as timely as you might've expected. As part of Developer World's piece, Fredrik Ekstrand, our Head of Software Product Management, elaborates on some of the reasons for this, but essentially - we've heard your frustrations and are constantly improving the way we do things."
