Camera, apps, battery and navigation fixes included
After pushing out updates to Jelly Bean earlier in the year, Sony has released maintenance updates for the Xperia S, SL and acro S to fix issues based on user feedback. On the camera front, Sony has fixed issues with white balance in pictures, improved the "quick launch" button and improved 1080p video recording to reduce lag. In terms of apps and data, EAS (Exchange Active Sync) has been streamlined, 2G network stability is improved and an issue that removed third-party default app preferences after a reboot has been fixed.
Battery life should improve with the latest update due to improvements in power consumption and heat dispersion, and battery level notifications have also been corrected. Working to build a more consistent navigation experience, the home key will now access Google Now when long pressed, and launch recent apps when double pressed.
Sony says that these handful of fixes will be coming to all three handsets, with variations in availability based on market and carrier, naturally. This is a good grouping of fixes and improvements, so keep an eye out on your own handset.
