Hello. Yes! I have the same problem. The constantly subtle changes in the light of the phone which are really annoying, also the screen is darker than it used to be. Had to turn off the auto adjust feature too. Just updated so haven't noticed other problems yet, but I am worried about the battery drain problem people have been talking about. Sony please do something and don't mess peoples phones with updates.
Update to my reply above: This thread is apparently for non compact X, accidentally posted here when this popped in the suggestion when making new thread to X Comact site. So my device is Xperia X Compact.
