I'd suggest that you backup your phone then do a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory, thus fixing various software-related issues. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable.
