[Samsung Galaxy A54 5G] BlackMesa123:
So by checking the optics partition I can see where the Caller ID feature is enabled:

➜ optics grep -r 'whitepages'

In the case of the EUX CSC, it is enabled for the following countries:

<Country countryISO="AT">AUSTRIA</Country>
<Country countryISO="CH">SWITZERLAND</Country>
<Country countryISO="CZ">CZECHO</Country>
<Country countryISO="DE">GERMANY</Country>
<Country countryISO="ES">SPAIN</Country>
<Country countryISO="FR">FRANCE</Country>
<Country countryISO="GB">UNITED KINGDOM</Country>
<Country countryISO="HU">HUNGARY</Country>
<Country countryISO="IT">ITALY</Country>
<Country countryISO="LU">LUXEMBOURG</Country>
<Country countryISO="NL">NETHERLANDS</Country>
<Country countryISO="PL">POLAND</Country>
<Country countryISO="PT">PORTUGAL</Country>
<Country countryISO="SE">SWEDEN</Country>
<Country countryISO="SK">SLOVAK</Country>

Which is very strange since my phone with EUX CSC doesn't have this feature either (I'm italian), maybe something else is going on?
