@Ruben Faustinita, Thanks for the posting in Q&A. Based as I know, if dialer and messaging apps within the personal profile are allowed to access the local contacts within the work profile, you can save numbers automatically in the contacts application, but this behavior is dependent on the specific device manufacturer or configuration. It is also possible that some dialer or messaging apps don't properly support this capability, which could limit their ability to access the contacts application in the work profile.
For the configuration, you can configure "Data sharing between work and personal profiles" to allow the data sharing and see if it can work.
If there's any update, feel free to let us know.
