No text magnifier in input fields or when selecting text

On android there is a built-in text magnifier (돋보기 위젯  |  Android 개발자  |  Android Developers). It pops up to help with accurate placement when you touch a selection handle and drag it.
However, on samsung phones(android 9+) there is no text magnifier when you drag a selection handle.
Can it be somehow turned on? Is it intentional behaviour or is it a bug?

Hi,
According to the documentation, it should work in Android 9 (API level 28) and higher. May be you need to turn on the magnifier.
