I'm having a problem with my X10 ringtone. Instead of the normal ringtone I have set up and has been working normally since I started using the phone, I now get a horrible quick-beeping notification tone whenever I receive a call/text. I have tried going into Settings>Sound&Display and re-selecting the appropriate ringtones and notifications but this makes no difference. I still get the fast beeping as my alert tone. When I check what tone is selected, my current tones are still set. Has anyone else had this problem and resolved it? I'm at my wits end what to do and would appreciate your expertise and suggestions.
