Samsung user here. I’m working with a Galaxy S22 Ultra, Galaxy Tab S7+ and a Dell XPS 9310 running Fedora. Set KDE Connect to never sleeping on the Samsung devices and it will work flawlessly. Transferring files, copy paste between devices, notifications etc just work for me. The only platform where I felt KDE Connect didn’t work smoothly was my Windows gaming machine. I gave in and just used the Microsoft phone connect app for that machine but everything else it’s KDE all the way.
Disable battery optimization for KDE Connect on Android. (If you’re on Samsung you might be screwed. They did weird stuff with optimizations.)
