Why does it change settings???

[carasdude]

On occasion I will restart my phone ( to help extend battery life and shut down various apps ) to clear out the cobwebs, but I have noticed that from time to time, my phone decides to reset my notifications, ringtones and so forth, back to either some sort of a factory settings or a mixture. I have my own settings that I have set as " custom 1 ", and the personalizations screen shows that as active, but when I look at the other drop down menus, it shows something different for each setting.

Any ideas as to why or how to keep it from doing this? ( besides not re starting the phone )

Thanks in advance.
