MOD + up/down shortcut not working for Galaxy S20

[VivekIly]

When I connect my Samsung Galaxy S20, I cannot control the volume of the phone using the MOD + up/down shortcut. I was able to do it with my previous phones (which were the S7 and Moto G7 Power), but can't seem to work it with the S20. I am able to use other shortcuts, such as MOD + R to rotate screen and MOD + O to turn off device screen.

Is anyone else having this problem with an S20? Am I doing something wrong?

Please let me know.

Thanks.

This happens to me as well, but I am on Xiaomi Redmi K40, Android 12

Did you test with either Super or Alt? Or with other supported --shortcut-mod?

Some of them might be intercepted by the computer system.

I tried with the --shortcut-mod=rctrl, the other shortcuts keys that I use, like home, back, notification panel and app switcher work as intended, only volume up and down doesn't work.

By the way I am on windows, so for the first question I am using the left Alt key, I hope I answer the question

Does this work:

adb shell input keyevent VOLUME_UP

?

[hafizidev]

adb shell input keyevent VOLUME_UP

Yes, the adb shell command works, tested with volume down as well, both change the volume

[rom1v]

Please run scrcpy in verbose mode (scrcpy -Vverbose), focus the window then press MOD+up once, then close.

Please post the whole console output (as text).

OK, so it looks lile it's correctly requested from the client to the server.

According to your previous test, I guess that this also works:

adb shell input keyevent 24

?

Is there anyrhing relevant in adb logcat when you press this shortcut from scrcpy?

[rom1v]

Could you please try with this version: #3190 (comment)

[hafizidev]

adb shell input keyevent 24

This does work the same, it raised the volume

#3190 doesn't solve it, still can't raise volume using shortcut key

[hafizidev]

@rom1v for me this issue happens when the music application in the background, while still opens the application, i can change the volume using shortcut keys just fine.
