To address several relatively minor problems and requests, Sony’s Xperia Z2 and Z3 devices will be getting an update to their firmware. They will remain on 5.0 Lollipop, which speaks to the fact that these are mostly optimizations rather than wholesale changes. The headlining feature is probably the fact that the app switcher now has a close all button, but there are some other goodies as well.
Another feature change is making the LED light independent of the sound settings.
