But I think it has some major usability issues. The two things I struggle with the most:
1. Sometimes (not always, but often!) the phone is not connected to the computer at all. In order to send something from the computer to the phone, I have to unlock the phone, find KDE connect in the apps, run it, and connect to the computer. I understand that this could very well be just The Way of Android, but it's still obnoxious.
2. The text/SMS sub-app in KDE connect is terrible. It doesn't sync text messages in the background, so it tries to sync when you start it. But it's very slow and takes a good 5-10 minutes for all of your text messages to sync. And apparently it does contacts last because in the beginning you only see phone numbers. And it doesn't show pictures. And (this is normally not a complaint I make), it is very ugly. GS Connect looks way better, but I have no idea if it _works_ any better.
