Randomly one day, without me doing anything at all to my phone, all of my native apps (aside from SMS, Phone, Settings, and Clock) stopped working. They close immediately upon opening. The only leeway is I can see what Mail I received, but I cannot actually open it up and read it. This doesn't happen with any other third-party apps. This happened before I updated to 4.3.3, and was not solved at all when updated. I've tried restoring and such with no avail. Is there anything else I can do to solve this problem?
