As part of its Concept for Android program, Sony has started pushing out a new update to participating Xperia X units. The update arrives as build number 38.3.1.A.0.74 and brings along a couple of major changes, including AptX support.
With the update, users will be able to enjoy hi-res Bluetooth sound using the AptX codec. “If you are a fan of hi-res Bluetooth sound but are not fortunate enough to own a pair of awesome Sony headphones with LDAC support, this release might be something for you,” the company said in a blog post.
In addition the update (which is currently hitting the experimental track on Xperia X Concept) also includes Android security fixes for the month of March.
