Default Permissions

With beans build 8 and now 9 I am having issues with cameras both 4.1 and 4.2 version not saving photos. I check permissions with root explorer to see it is set and keeps reverting back r/o. I change it to r/w and after a few minutes it fails to save photos again and reverts back to r/o. Can anyone advise what they think my problem is? Thank you
