French operator SFR has released its latest software roadmap for the devices it offers and confirms that Android 5.1 Lollipop will be landing from August 2015 on its Sony Xperia models. Sony Mobile expects the update to land from July, so an August launch for carriers seems about right.
Interestingly, looking at the release phasing suggests that the Xperia Z3/Z2/Z1 series will see Android 5.1 from August, whilst the original Xperia Z series will have to wait until September. SFR has no confirmation of when Xperia M2 will get the Android 5.1 update, which could mean it won’t launch until late summer at the very earliest.
Thanks François, mukul and walaspancha!
