@defim finally narrowed down a major issue I've been experiencing on my Samsung Galaxy S5 4.4.2 stock device... when I go into Android Settings > Network Connections > More networks > Default messaging app I should see a list of apps on my device available for messaging, in which case it should be Messages, Hangouts, and Titanium Backup. With the CustomShare module loaded all I see is what's set as my app of choice, so the other two don't even show up. This is a problem because I use Titanium Backup to backup/restore text messages and the way it does this is it sets itself as a messaging app during a restore, but with this module loaded there is no such option so it hangs. Please let me know what info you need to look into this as the Xposed Installer logs look clean.
Btw, if you select an app with phone/sms permissions in CS, eg TB then a warning pops up.
