Honestly I haven’t tried, so that’s possibly on me. But also I don’t want it on there, who knows what that app does, it’s at best suspicious, imho. I have a “dirty” phone with all the big tech stuff on, but at a pinch I can make it go online using my “clean” phone as a tether, but I’m trying to wean off the data harvesting apps like WA, Instagram etc

No, I think they support others too. However I have the Jolla C2:

I’m currently trying to switch to using my Sailfish Phone full time. Unfortunately the way I’m having to do this is by keeping my old android about to run WhatsApp (because I can’t get friends and family onto something that also runs on Sailfish, which is basically Matrix or nothing as far as I can tell). It’s not great tbh, but I really like the idea of Sailfish (or Ubuntu touch).

The Dalvik layer (which runs the Android sandbox) is ok, it runs some stuff but not everything and anything “security dependent”, forget it, so Banking and messaging won’t be supported, that being said the moment I find a bank that supports Sailfish, I will switch to that bank in an instant.

(Ps. If anyone has anything to refute any of my statements here, like a good messaging app or banking, then please correct me, I want to be wrong)
