**Issue Description:**
* I ran `scrcpy` it mirrored the screen but I'm unable to to control the device using the mouse and keyboard.
* The shared phone screen on my Ubuntu is on Read-Only mode.

**NOTE:** I don't have `USB debugging (Security Settings)` setting on my *Samsung S23 Ultra*

**Ask:**

* Is there any equivalent setting to the `USB debugging (Security Settings)` that must be enabled to be able to control the phone ?
* Or is this caused by an other issue ?

Start by reproducing the reported `scrcpy` command with Ubuntu 23.10, scrcpy 2.3.1, and the Samsung S23 Ultra on Android 14. Investigate the reported absence of USB debugging (Security Settings) and whether mirroring works while input control is unavailable. Done means identifying a supported setting or confirming a device-specific limitation.
