<Moderator Edit>: Thread closed due to the original developer @Jacopo Mii already having a thread for this at [MOD][ROOT] GoogleDialerMod.
Some of those flags concern Google Dialer core functionalities, while others are about hidden or upcoming features not yet released.
What this app does is execute SQLite queries on that database and overwrite Google Dialer configuration files to enable or alter its features at will.
Furthermore, by opening the individual recordings, it is possible to share them using the apposite button:
Among the sharing options, there is also the possibility of copying the file to a folder of your choice:

Downloads:
- Please visit the GoogleDialerMod Release Page
How do I use it?
- Always make sure you are using the latest Google Dialer beta from the Play Store to enjoy the latest features
- Allow root access to GoogleDialerMod, apply the tweaks you want, then force close Google Dialer app and reopen it a couple of times for them to take effect
- There is no need to keep GoogleDialerMod installed after applying the desired mods, because they (should) survive Google Dialer updates / reinstalls over time
How does it work?
In every Android device there is a database, called Phenotype.db, managed by Google Play Services, containing special flags that affect the behavior of all Google applications installed.Some of those flags concern Google Dialer core functionalities, while others are about hidden or upcoming features not yet released.
What this app does is execute SQLite queries on that database and overwrite Google Dialer configuration files to enable or alter its features at will.
Current features:
- Supports arm / arm64 / x86 / x86_64 devices and (hopefully) all Android versions
- Enable / disable hidden features for all users at once when Android "multiple users" mode is in use
- Force enable call recording feature even on unsupported devices or in unsupported countries
- Enable also automatic call recording feature based on caller (otherwise only available in India)

Furthermore, by opening the individual recordings, it is possible to share them using the apposite button:

Among the sharing options, there is also the possibility of copying the file to a folder of your choice:

- Silence the annoying "registration has started / ended" call recording sounds
- Force enable call screening and revelio (advanced automatic call screening) even on unsupported devices or in unsupported countries
Troubleshooting:
- After enabling / disabling any switch, please force close and reopen the Google Dialer app a couple of times. You may also need to reboot for the changes to take effect.
- Before to report an issue try to delete Google Dialer app data, to reboot your phone and to try again what didn't work
