Between 1.19 and 1.20, this is probably due to this commit 8df42cec82cb5856e6c10a4089e6b2953310da6e. Let's try with this quick&dirty change: ```diff diff --git a/server/src/main/java/com/genymobile/scrcpy/Workarounds.java b/server/src/main/java/com/genymobile/scrcpy/Workarounds.java index 448e7099f..db0d72789 100644 --- a/server/src/main/java/com/genymobile/scrcpy/Workarounds.java +++ b/server/src/main/java/com/genymobile/scrcpy/Workarounds.java...

Oh great! Could you then test this new one and confirm that it works: - [`scrcpy-server`](https://tmp.rom1v.com/scrcpy/4922/2/scrcpy-server) `SHA-256: 7cb3bc939c91e23788ed3f2801f71b9cc8f258e85bed7b60fc98ece9721bbe1` Here is the diff: ```diff diff --git a/server/src/main/java/com/genymobile/scrcpy/Workarounds.java b/server/src/main/java/com/genymobile/scrcpy/Workarounds.java index 448e7099f..3f86f892b 100644...

> Device: [skyworth] Coocaa 7T872_P60P (Android 10) Oh in your case, the manufacturer is still `skyworth,` but the brand is `Coocaa`. Let's test the manufacturer instead: ```diff diff --git a/server/src/main/java/com/genymobile/scrcpy/Workarounds.java...

:+1: Merged into `dev`: b50f9eb41d1bd7b75a77e2c388b0144365e3cd5f :rocket:

Something has been changed in your rom by the vendor. Please post your `framework.jar`. Download it from your device with the following command: ``` adb pull /system/framework/framework.jar ```

> scrcpy 1.12.1 Too old. Install the latest version manually.

Could you please test with the `scrcpy-server` posted in #4392?

OK, some parts require `ActivityThread.currentApplication()` to return a non-null `Application` (for audio and camera for example), but if it is not null, some other parts (`InputManager` in your ROM) perform...

Which device? Which Android version? Which scrcpy version?

Start with `scrcpy -Vverbose`. What happens in the console when you press B in the scrcpy window? What happens when you press another letter?
