I'm running stock except for nova launcher and fancy widgets. I have just noticed now that when I lock the phone and then unlock it, the phone is unresponsive for a couple seconds because I notice some type of sparkle animation that is happening. I have gone through all the settings and made sure I didn't have weather animation after unlock turned on or any other type of animation after unlock. Does anyone know what could be the issue? The animation looks like stars twinkling or something. I've tried changing the wallpaper to something else as well. I've gone from live wallpaper to a still wallpaper. The live wallpaper I run is ocean HD. Any help or suggestions would be appreciated.
