Right this isn't a big deal but I'm intrigued by this behaviour. I recently set my phone up as new but copied over the camera roll from my backup. I copied it over onto the new phone but noticed problems straight away. The camera wouldn't save pictures and kept hanging on certain things. Straight away I knew it was a permissions problem but why? The permissions on the photos folder was 644 before and I had to change it to 777 to get normal behaviour. Why did the phone work before with 644 permissions but need elevated 777 permissions on the new phone?
