How to find out if the hidden caller id is enabled or not in android?

Here is an indirect solution that allows us to hide our number, i.e. hide caller id. But how can I find out if the user allowed the parameter to hide the number or not?

I have seen many SO discussions like this and this , but so far no one has helped me.

Thanks everyone

Unfortunately, I believe that there is no native solution for this. In addition, I remember that in some previous versions of Android (I currently use Jelly Bean 4.3 ), when I manually turned on caller ID hiding, the calls in the call list turned out to be #31#XXXXXXXXX , representing #31# hiding the caller ID .

It doesn't seem that the prefix even appears in this version, so with at least the explanation above, you can statistically determine if it was turned on or not, but now I believe there is no way.
