Sony is rolling out new firmware updates for its flagship model Xperia Z2 and Xperia Z2 Tablet. Earlier in the month, a new firmware with build 17.1.1.A.0.402 had been certified for the two devices to follow the current build 17.1.A.2.69 existing in them.
The Android 4.4.2 KitKat based new 17.1.1.A.0.402 firmware brings various improvements in performance including touchscreen sensitivity according to some preliminary reports. However there is no exact information about it since no changelog has been provided by Sony. It is also not known if the 4K recording performance of the Xperia Z2 has been improved upon to overcome the forced shutdown problem.
The firmware update is available for the Xperia Z2 D6502 (HSPA+) and D6503 (LTE) models. In case of Xperia Z2 Tablet, they are available for SGP521 (LTE) as well as SGP511/SGP512 Wi-Fi models. The update is downloadable through Sony PC Companion suite and is available in Germany, Russia, the Nordic region and other countries.
