Could try a soft reset (hold volume down + power until it reboots and vibrates), but most likely if you are seeing software issues too, then you might consider a hard reset. A hard reset would erase your apps and settings, but as long as you are on W10 Mobile you can back most if not all of them up during a restore from backup. It is not guaranteed to fix it but it is worth a shot. Also depending on which apps you have you may not be able to restore them, like if they were deprecated recently or something.
