Those who have updated their Xperia M to the latest firmware version 15.1.C.2.8, plz do share the new features, improvements and problems if any....
Sony was making this version over month but the firmware is still underdeveloped.
Sony should fix these bugs:
-volume of sound is too low(calls, music, ringtones)
-Sony don't fix calibration of dispaly
-front camera has poor sharpness, blurring in the corners
-rear camera is a little better, but still not perfect
-bad call quality(to much noises)
-weak GSM/UMTS range

i like it
One new feature in this udate is, that Sony completely deleted all live wallpapers 
I really liked the cosmic flow wallpaper.
Only Sony knows why the they don't offer the live wallpapers anymore.
Does anyone of you know a way to install these wallpapers seperately? And please do not post links to mediafire. I want to be sure that any packet I install will come from an official site.
You can found this live wallpaper here: http://forum.xda-developers.com/showthread.php?t=1640139
