New firmware (9.1.A.1.138) has been certified for the Sony Xperia T (LT30p) and Xperia TX (LT29i), which Sony says will arrive in the week commencing 1 April. The firmware will introduce Android 4.1.2 Jelly Bean to Xperia TX owners, who have patiently been waiting for the update. It will also introduce a fix for the problem people have been having with the Walkman app on Jelly Bean firmware.
People have reported issues with the Walkman app freezing when the display locks, with long delays in between songs. Another firmware version (9.1.B.0.411) was also certified on the same day, but we expect version 9.1.A.1.138 to see a wide rollout.
Thanks Silas and ??????!
