EditText inputType problems with Samsung A50

Question

This works in a vast phone model list except for the Samsung A50:

<EditText
    ...
    android:digits="0123456789-"
    android:inputType="numberDecimal" />

This is the "hotfix" work around:

<EditText
    ...
    android:digits="0123456789-"
    android:inputType="phone" />

Any idea, other than it's a Samsung, of the reason on why this is failing?

android:digits="0123456789-"
android:inputType="numberSigned"

Output from A50S:
