I've been having issues ever since Motorola updated Droid 4 to ICS. The phone worked blazingly fast and never had any issues until the update. Now apps like browser, e-mail, and more constantly lock up and crash. The phone constantly locks up and freezes on me, and it generally runs like a Commodore 64. Like I said, it didn't happen before the update. One of the biggest issues I have been having is the inability to answer phone calls. The screen locks up and it is a full 30 seconds before it will let me accept the call, and even then it will take a bit longer to connect to the call.
