I know that this latest update was supposed to fix the bug where the wrong ringtones were being played when a custom ringtone had been set; however, now I am seeing a different issue with ringtones/notification sounds. After receiving the update on 12/21, I have noticed that my ringtones and notifications sounds no longer stay set. I noticed it when my email notification sound started playing some mp3 that I had on my phone and as I was looking further, all of my contacts that I had given custom ring tones were now set to some other ringtone. I reset all of custom ringtones on my contacts and notifications sounds that I had noticed had changed. This morning....many of them were set to something else again. Including the gmail app notification sound (again). Is anyone else experiencing this issue.
