Sony Mobile has released a small bug-fixing update to the Walkman application that moves the build number from 8.5.A.2.7 to version 8.5.A.2.8. This may bring a fix for the illumination bar support on the Xperia SP that stopped working in the last update, but we haven’t had a chance to test it ourselves. If you have noticed any changes, please chime in below.
Update: We can confirm that the Xperia SP illumination bar is now fixed.
