Firmware version 17.1.1.A.0.402 was recently released for the Xperia Z2 and Xperia Z2 Tablet. Well it looks like another update is on the horizon, this time with build number 17.1.2.A.0.189.
A screenshot with this build number shows the new firmware running on the Xperia Z2 HSPA+ (D6502). If we do see it released, it would move the firmware from build number 17.1.1.A.0.XXX to 17.1.2.A.0.XXX, suggesting a reasonable bug-fixing update if nothing else. We’ll bring you more news as we have it.
