Android screen mirroring tool scrcpy’s latest update brings keyboard and mouse passthrough without USB debugging
The scrcpy (short for “screen copy“) tool allows you to mirror your Android device’s screen to a PC or Mac. The popular open source project has been steadily gaining new features and functionalities over the past months. Back in July last year, the app brought support for Android 12, introduced the ability to use the video stream as a webcam on Linux, and more. Now the development team behind scrcpy has released a fresh update that adds support for OTG mode, improves the overall user experience, and fixes multiple annoying bugs.
The main highlight of the scrcpy v1.22 release is the introduction of physical keyboard and mouse simulation, dubbed as OTG mode. While HID keyboard simulation has been supported by this tool since the v1.20 build, the latest update finally enables HID mouse support. As a result, you can now use your PC’s keyboard and mouse to control an Android smartphone as if they are plugged directly to the target device via an OTG cable.
The screen mirroring feature will not be available under the OTG mode. Instead, you will see a window with the scrcpy logo, which will forward the keyboard and mouse events to the remote device when focused. Notably, this feature only works under Linux for now.
Perhaps the most interesting part of scrcpy’s keyboard and mouse passthrough implementation is that it doesn’t require ADB access. It means you can even use this feature on a device with USB debugging disabled. This is particularly useful when you need to deal with a smartphone with a broken touchscreen, as you can simulate the input events and enable USB debugging. Next, you can backup your personal files, or can run scrcpy normally in order to remotely control the device.
The full changelog for the scrcpy v1.22 is as follows:
- Add HID mouse support
