Update Sony Xperia S LT26i to Android 4.1.2 Official Firmware [6.2.B.0.200]

After the successful launch of Xperia Z, Sony has finally started rolling out Jelly Bean update for their previous flagship device Xperia S LT26i. This update has build number 6.2.B.0.400. Being a Jelly Bean update, it is way smoother than the ICS update (thanks to project butter). Its has new homescreen with 7 panes. Sony has removed the Stamina mode, only Extended Battery mode available. This update includes new media apps of Walkman, movies, album, radio etc. Camera seems to be working faster. Also, no RAM change is found in this update i.e, RAM remains 685 MB only (which is same as GB & ICS).

Till now, we discussed about pros of Android 4.1.2 firmware. Now, lets discuss some cons of the same. First of all, video recording in 1080p is lagging very badly. The video capturing frame is not steady at all. Secondly, battery drains very fast irrespective of the network mode you use. And as reported by some of Xperia S users, this firmware has some connectivity issues i.e, mobile data / Wi-Fi doesn’t work sometime.

That’s all with this firmware. But still I would recommend you to try out this firmware. Lets checkout how you can upgrade your Xperia S LT26i to Official Android 4.1.2 JB firmware (6.2.B.0.200).
