There are lots of to be had subject matters on the Play Store and the web that may utterly amendment the glance of your telephone on the fly, and it’s one among the largest issues that’s been lacking from Cyanogenmod 12.
Fortunately, seems like so much of the exhausting paintings is over, as CM 12 nightly builds now have the topic engine baked in. The problem here's that many, however now not all, older topics have problems operating on the more recent topic engine, and a few of them don’t in fact paintings in any respect.
