There does not seem to be really any good FOSS SMS apps. I really like the UI of Simple SMS by SimpleMobileTools but the group chats are so glitchy that I have no clue how that application is anyhing but an alpha release. Is there anything similar to Simple SMS that works? I know QKSMS got abandoned
I just use the AOSP messenger. If I used google play services, I would switch to Google messages because of RCS and it looks much nicer.
Google deprecated both AOSP phone app and AOSP messenger app a few months ago. Normally, there should be a surge in FOSS replacements for both apps as they are needed by ROM makers to have a good experience (also: i understand it’s not necessarily the most exciting kind of apps to dev yet they are probably among the most risky privacy-wise to make)
