Hi! I downloaded some ringtones from Zedge and they work great---half of the time. If I turn my phone off and then back on, the notification, email, and actual ringtone will work fine. After about an hour or so, any time I get any sort of notification, it only vibrates. I have checked the settings, I have reactivated my phone, I have re downloaded my ringtones---nothing. Is anyone else having this problem? Do any of you have suggestions as to how I can fix this? I've been looking it up online and have yet to find any promising suggestions. Thanks!
