I noticed since the jellybean update my phone takes quite a while to start up. I get 5 different screens before the home screen shows up. The black screen with the white Samsung logo, then the Samsung Galaxy SIII screen, followed by a Samsung oval logo with animation, then the Sprint Lte screen and finally the black screen with the white logo comes up again at the end. I dont remember it taking this long to start up with ICS. Is that normal or did I download an unofficial zip file.
