@aral There are other secure messaging programs that work just fine on the Pinephone like XMPP. However, there is one big drawback with any internet-based messaging on the Pinephone. You have to choose between decent battery life and getting notifications of new messages. To get acceptable battery life the system must suspend and the only thing that will wake it up is a phone call or SMS. If you want the network to stay connected to receive and notify of new messages then you have to keep it from going to suspend which significantly reduces battery life.
