LG Optimus L9 getting Android 4.1.2 Jelly Bean with T-Mobile

Posted In News - By AndroidPress on Monday, April 22nd, 2013 With 1 Comment

LG announced Jelly Bean for the international variant of the Optimus L9 back in mid-March. That update began rolling out immediately as was expected, however it left things up in the air for those with a T-Mobile branded Optimus L9. The good news has arrived though, T-Mobile has begun updating the Optimus L9 to Jelly Bean.



Specifically, the LG Optimus L9 is getting Android 4.1.2 which will be arriving with baseband version P76920d. The update is available over-the-air and will measure in at 350MB in size. Those with a T-Mobile Optimus L9 now have two options to consider. The first being to sit back and wait for the update notification to arrive. The second option is the one we suspect most will follow though — checking for it now.

If you are taking option number two, grab your handset and once connected to Wi-Fi, navigate to Menu -> Settings -> About device -> System update to get the process started. From here, and for those who have received the on-device notification — you can simply follow the prompts to get the update process completed.

T-Mobile hasn’t offered anything specific in terms of what the update will bring. The changelog is simple and to the point and mentions only that the operating system is being updated to Jelly Bean. Of course, we know that Jelly Bean means some additional features and improvements. Just to name a few, those updating will have Google Now as well as the improved (and actionable) notifications.
