New upgrade issue.

[Mordsith_T]

Ever since my phone got the update it is crashing regularly.   I have to hit the power button to get it to turn on(wake it up) rather than the home button.  The phone call app keeps changing to an absolute basic mode where I do not have access to recent calls, favorites, and contacts.  I have to restart the phone to get those features back.  I also cannot turn on the Advanced Calling feature.
