Silent mode is little bit buggy?

Hello /e/ community,
last days I use something more the silent mode automatically with its own activation schedule task in settings.
And I remarked that more than 50% the time (maybe 75%), that after activation some sounds like keyboards sounds or videos music may be still eared from the phone speakers.
Activated manually it works 100% (silent), but as automatically activated from it scheduling task, don’t works (phone still noisy) and should be deactivated and reactivated manually.

Some other people face the same small issue ?

My device is Samsung galaxy s10+ /e/os v1.15

Cheers all
