I’ve been running CM for almost six months now and have played with many different options and settings throughout and am very happy now with the following settings. This might be helpful for others thinking of ditching the stock Android and HTC Sense software.
Well, that is what I’m running now but it might change. I have tried Art runtime often, but have not yet found any advantages. The AT&T Visual Voicemail is buggy on KitKat, but I’m hoping they will eventually stabilize it again.
Hope this gives you another point of reference. I love the HTC One hardware, and CM really makes it sing.
