I'm having an issue with the boot time on my galaxy s4 (jfltetmo m919). When I press the power key it hangs at the Samsung Galaxy S4 splash screen (with selinux enforcing etc). It hangs on that screen for 40 to 50 seconds then it starts the boot animation. Booting then takes 20+ seconds. Why does it hang at the splash screen and can I do anything about it?

Model - SGH-M919
ROM - CM12 NIGHTLY official
Recovery - TWRP 2.8.6.0 With f2fs support
