I want to apologize for the late reply. I haven't read my emails for the past few weeks. The "Preparing your home screen " usually happens when I have the apps that are running, which I would normally not closed. Before the update normally I would leave the apps open in the background, so probably I have 3 to 5 apps running, but the "Preparing your home screen " doesn't appear. However, After the update even if one app is opened and I ruturned to the home screen the "Preparing your home screen " wil appear afterwards. I hope this information could help resolve this problem. Attached is the screenshot your requested.
Regards,
Hanif
