samsung a56 - disable assistant google on home button has no effect

[SeraSan]

I tried to disable assistant google on home button but doesn't disable it!

Here's how to change the default digital assistant app:

1. Open Settings: Navigate to your phone's settings menu.
2. Go to Apps: Find and tap on "Apps" or "Apps and notifications".
3. Choose Default Apps: Look for "Default apps" or "Choose default apps".
4. Select Digital Assistant App: Find the "Assist and voice input" or "Digital Assistant App" option.
5. Set to None: Choose "None" as the default assistant app.

The above works on older samsung but not on the A56 (Android 15 One UI 7.0), maybe a bug?

Any clue?
