try to perform a software repair using xperia companion
Hello @Mariosamego81 and welcome to the community!
I'd suggest that you do backup your important data, then perform a software repair using Xperia Companion. This will do a clean installation of the latest firmware and will also wipe your internal memory. Follow the steps given in the blue link, do not connect your phone until prompted to press volume down while plugging USB cable.
It depends on your phone's model, customization version, and region. Performing a software repair using Xperia Companion will fix those issues you have AND update your phone if there are any available updates.
You can also connect your phone to a PC/Man with Xperia Companion installed and check for updates if you don't want to wipe your phone.
