6wheel, yes, most missed calls are, I believe, when she is playing her beloved WebOS scrabble, so that is a big CPU hog.

I could be wrong but I think CSSU introduced a more animated double fold-up animation vs the simple and less GPU/CPU stressful rotate I remember from pre-CSSU.

@biketool,

You could also just disable rotation completely (e.g. disable the accelerometer module in mce.ini).
