I'm liking it very much and it's the only messenger client I use regularly. I made it replace the Sms default app, so either comunicate with me with sms or signal. I don't support whats app because it's close source neither telegram for the bad crypto. I don't have any problems with signal on android. Only thing missimg is more ppl using it. If someone wanta to chat me otherwise they can go with the usual classic waya like facebook, skype, email or discord. But in replacing those only with something better, so never whatsp App or telegram.
