Just yesterday, a new update started rolling out to users f the Xperia L2 smartphone. As at that time, there was rarely any change seen in the unit as to what the update does. Sony, in a bid to fix that apparently, has started rolling out yet another update to the same smartphone.
This new update brings along with it the Android security patch for the month of March. If you wanted to check if the change has been applied to your smartphone, you will find out that the build number moved form 49.0.A.3.72 to 49.0.A.4.55. For now, though, we don’t think any additional features come with the rollout.
Given that the rollout has just started, it might take a while before it gets to your unit. There is the possibility that it is a batch wise release to various regions. Let us know as soon as hit hits your device and what region you are registered to.
