Xperia T and Xperia V saw 9.2.A.1.199 firmware getting certified for them at end of Feb while nothing was certified for Xperia TX but something surprising came today, a user got 9.2.A.1.199 firmware update notification on his Xperia TX LT29i. We checked via update checker app and found now new update being rolled for his phone customization, it seems Sony has either rolled it for some particular regions or it is still seeding as 9.2.A.1.199 firmware was certified for Xperia T and Xperia V so it may end up rolling later on.

9.2.A.1.199 firmware keeps on Xperia TX on android 4.2.2, seems a minor bug fixing update only. 9.2.A.1.199 firmware update came as OTA notification of 8.3 MB. So try it on your Xperia TX you may also have got the 9.2.A.1.199 firmware update notification or will get it later, keep checking it.
