High CPU usage and no sleep after upgrading to 4.4.4
You could disable the Media storage app, which solves the issue, but also breaks the stock Gallery, video, and music apps, and completely breaks ringtone selection, even if you use another app to select one. If you could live with that, disable the Media Storage app. You will need root for this. If you don't want that, you can install Advanced Permissions Manager, and remove the permission Keep Device Awake from the Media Storage app. You will NOT need root for this, and everything will keep working, and the MS app will not keep the device awake all night.
