Hi! I have my M4 Aqua for over a year. I know how it works. I know how to set almost everything but...I don't know how and why my ringtone is stuck with the "Experia". I choose the "Bell phone" ringtone, confirmed my choice. When I call myself with a "hard line" phone, it's always the "Experia" ringtone I heard and it's to calm, I can't ear it! I close my phone, restart it and nothing has changed! Sorry for my so-so english im a french guy! Thanks
