Old thread, related discussion: I have a question about using the Android app of Signal Messenger on Sailfish. I have installed AlienDalvic Control. And within the settings for that app-->App Permissions-->SMS, it has 0 of 1 apps allowed for SMS. However, under default apps it shows Signal as the SMS app. How can I turn that off? I ask because I worry that is causing at least some of my problems. There is no way, within Android, to assign a Sailfish app as the default app. So it seems like this asks for trouble. And I am having them. At this point if someone sends me an SMS or MMS, Signal Messenger stops communicating. And I have to go into Sailfish settings-->Utilities-->Restart Home Screen in order to get it working again. This is not great.
