Do Apps like Google Assistant work on Blloc Zero18? Do Apps like Google Assistant work on Blloc Zero18?
Because this is a minimalist phone with its own UI
Optionally.
From the Blloc site

Start your smartphone experience differently with Blloc: the real (non-Google) stock Android experience without any forced Google services.
Zero18 comes with the Blloc MNML operating system—a distraction-free custom software built on top of Android 8.1

So out of the box there appears to be NO Google Services.
Google Assistant, Google Maps, Google Mail, Google Translate all require Google Services to be running on the device.
Therefore from the Blloc help/wiki page: it seems you would need to manually install Google Services (basically flip a special settings switch and reboot) so that the device could get Play Store apps.
I'm unclear/doubtful that some of the deeper integrations of Google Assistant like being able have the phone passively listen for &quot;wake words&quot; to enable a voice assistant would be possible on this device.
You have the option to use alternatives to Google Services
