I noticed this problem for the first time yesterday. I also have Light Flow. Did a bunch of reading last night and tried several fixes, the only thing that worked included disabling Google's Text to Speech and Samsung's Text to Speech. I really hated doing that because I don't know if I will need them again at some point.. Did not want to uninstall Light Flow so I figured the sacrifice was worth it. Well, just a few mins ago I got an alert on my phone that there was an update for Light Flow - for the talking folder issue..... Grrrr.. I updated, now I have to figure out how to get back the Text to Speech stuff..
