@Wiktordoopy: If you're having connection issues with your S Pen, and placing it back in the holster doesn't re-establish the connection, then please try heading to Settings > Advanced features > S Pen > Air Actions > Tap the 3 dots in the top right > Reset S Pen. If the issue persists, leave the S Pen in its holster, then press and hold the Volume Down and Power buttons together until the phone restarts. Let me know how you get on.
