The Sony Xperia Z3 Dual (D6633) has seen a new firmware update certified by the PTCRB, unfortunately it is not the anticipated Android 5.0 Lollipop firmware. The minor update would move the current Android 4.4.4 KitKat firmware with build number 23.0.1.F.0.96 to version number 23.0.1.F.0.102. Expect this to bring bug fixes and performance enhancements. The wait for Lollipop continues for another day.
Thanks gmfady and Soheil!
