Setting up this Swiss keyboard on the Samsung Galaxy Tab S6 Lite is quite complicated. I've just had to do it for the second time because my Tab S6 broke and I've now installed a new one. Here are the steps (January 2024) Settings - General administration - Physical keyboard (the Targus THZ858 keyboard is listed here) - Now set the keyboard to 'Swiss German, Qwertz style' for all listed keyboards (not German (CH) or something like that!) Then the special characters @ [ ] using the 'AltGr' key will also work for me, as listed on the keyboard! Uuuff, I've been searching for hours for the second time. Digitec is the only place to go with the right solution :-)
