How To Know Whether Hiding Caller Id Is Enabled Or Not In Android?

Here is the indirect solution to enable the hiding of our number i.e. hiding caller ID. But how can I know whether user has enabled to hide the number option or not? I have seen ma

Solution 1:

Unfortunately, I believe there's not a native solution for this. Additionally, I remember that in some previous Android version (I'm currently using Jelly Bean 4.3), when I manually turned on the hiding of Caller ID, the calls in the call list appeared to be #31#XXXXXXXXX, representing the #31# the hiding of the Caller ID.

Seems that in this version it doesn't even appear the prefix, so at least with the above explained you could statistically infere if it was turned on or not, but now, I believe there's no way.
