After upgrading to Android 11, there is no longer a notification to use your phone as a touch pad. There is a pop-up that states to press a new navigation button, but the button does not exist. Samsung has also disabled the ability to access dex settings from the phone, so there is no way to access the TouchPad and keyboard settings from the device to set something up.
Ok I fixed it last night but I had to use a keyboard to do it. Here's what I did: 1. connected my bluetooth keyboard to the phone 2. navigated to the setting using the 'function' key to cycle through selections (this was the key to the whole process). 3. navigate to advanced features (its the same menu to change what the power button does.) 4. navigated in to the 'Samsung Dex' menu (you HAVE to do it this way otherwise this menu is locked in all other modes) 5. scroll down and select 'mouse/trackpad' 6. witch the switch on "show touchpad when DeX runs 7. disconnect the phone from tv/monitor 8. reconnect to monitor/ TV and the track pad Should automatically open on the phone's screen. 9. DONE! (Keep in mind if your settings are reset in any way you'll have to do this all over again.
