Recently Sony made a statement on their official blog that a major bug fixing android 4.2.2 update is rolling for Xperia Z1 and Xperia Z Ultra and also listed the changelog officially. Yesterday we saw 14.1.G.2.257 firmware update on Xperia Z1 which improves Camera, display and power consumption although on our experience of 14.1.G.2.257 firmware, except camera every thing is still buggy on Xperia Z1. It still has yellow hue tint and a lot noise in images taken from its camera app.
Our prediction of 14.1.B.2.257 firmware update to come on Xperia Z Ultra came true. Xperia Z Ultra has been updated to 14.1.B.2.257 firmware, a major update from the previous 14.1.B.1.532 firmware which has many issues like poor touch response, fake SOD issue etc.
14.1.B.2.257 firmware update is confirmed on both Xperia Z Ultra C6802 HSPA+ and C6803, C6833 LTE handsets, available via OTA as well as PCC and SUS. Confirmed in UK region. Below image via [ via XDA user avetny ].
