Anyone have used system UI tuner in F23 to enable second screen?
If you have tried then reply, if it works.

Playstore app:

Process to try

One UI has a feature called Second Screen that lets you mirror/extend your Windows PC's screen onto your Samsung device. However, this feature is officially only available on the Galaxy Tab S7, Tab S8, and Tab S9 series.

Fortunately, the feature is still there on Samsung phones and foldables like the Galaxy Z Fold 5, but you need to access its hidden settings page in order to use it. Here's how.

1) Download the SystemUI Tuner app from Google Play, go through its setup process, tap the "System" dropdown on the leftdown then select "Lock Screen". Tap on "Lock Screen Shortcuts", then pick either the Left or Right shortcut. Look for "Smart View" in the app list and then pick the option that says "SecondScreenActivity". 

2) Run the following ADB command:


After you do #1 or #2, go to the lock screen and open the shortcut you just set. It should launch the Second Screen settings page! The reason this works is because, although the Second Screen activity is unexported, the lock screen is part of SystemUI which runs as the system user which can launch unexported activities.

Now while you're on this page, hit Windows + K on your PC to bring up the Cast menu. You should see your device appear here. Pick it, and wait for it to connect. Once it connects, open up the Cast menu again and check the "allow mouse, keyboard, touch, and pen input from this device" if you want to be able to send inputs from your phone. That's it!
