How to Enable UHID keyboard in Scrcpy

This is a huge improvement for typing text, especially in non-English languages:

scrcpy --keyboard=uhid scrcpy -K # short version

It simulates a physical keyboard. Contrary to the default text injection method, it is not limited to ASCII and some other characters.

This is functionally equivalent to the existing AOA mode (--keyboard=aoa), except it is not limited to USB (it also works wirelessly) and it works on Windows while mirroring (and without driver issues).

The keyboard layout must be configured (once and for all) on the device to match that of the computer (that’s the reason why it’s not the default). To open the keyboard settings, several possibilities:

• from the scrcpy window (when uhid or aoa is used), by pressing MOD+k (see shortcuts)
• from the device, in Settings → System → Languages and input → Physical devices
• from a terminal on the computer, by executing

adb shell am start -a android.settings.HARD_KEYBOARD_SETTINGS

From there, it is also possible to enable or disable the virtual keyboard.

UHID mouse

Similarly, it is possible to simulate a physical mouse:

scrcpy --mouse=uhid scrcpy -M # short version

Like in AOA mode (--mouse=aoa), the computer mouse is “captured”: the mouse pointer disappears from the computer and appears on the Android device instead.

Special capture keys, either Alt or Super, toggle (disable or enable) the mouse capture. Use one of them to give the control of the mouse back to the computer.
