The Xperia Z1 started to receive a new firmware update yesterday, which added the White balance setting as well as introducing bug fixes. Well this 14.2.A.1.136 firmware update has now been certified by the PTCRB for the whole Xperia Z1 family (C6902, C6903, C6943, C6906) as well as the Xperia Z Ultra (C6802, C6833, C6843, C6806) and Xperia Z1 Compact (D5503). We’ll keep you posted when it starts to see a wider rollout.
Thanks Ben!
