Thanks for the email. I have looked at the logs but unfortunately they are all chopped.  The reason is that after Android 4.1 collecting logs have been blocked by new Android permissions. :/ I have searched to figure out a way to collect logs but I haven't found a great way yet...

I really want to figure out why the pause is happening. I'll try to see if I can get a hold of an S3 to test on.

Thanks for the log! Yeah for some reason the folder somehow disappeared while a static reference was kept and that caused a similar issue.  The cause could have been that the external storage was not available.
