This should allow you to use KDE in game mode, without dbus errors and some apps failing to launch due to them. To exit KDE, just log out from the launcher or run return to gaming mode, and press B once the bottom bar in the game mode UI shows up. Even tried using my spare Android tablet as a drawing tablet using KDE Connect once, but it's not that responsive, which is understandable, because it's not designed for that purpose. BUT, I connect my phone to my PC when I need to back-up photos and videos, because accessing files from my phone via my PC using KDE Connect is super slow. Provided that your PC and your Android are connected to the same WiFi network, launch KDE Connect on your phone and you should see your PC under Available devices. Tap on it and REQUEST PAIRING. You’ll see a notification on your PC, click on Accept and that’s all. Non-KDE users will need to request the pairing from the desktop indicator tZVW.
