I would like to delete all 2000+ Contacts stored on the Owner profile.
There are too many entries to manually select them 1 by 1 and then delete them within the Contacts app. The app does not offer a "select all" button, so deletion by this method would take many hours of tapping for such a large contacts list :(
I have already tried:
Settings -> Apps -> See all X apps -> Contacts -> Storage & cache -> Clear Storage
But this did not seem to work, even after restarting the device. I still see my contacts list.
Deleting the profile is also out of the question, as this is the Owner profile.
I have tried using certain apps like SMS Import / Export, but they do not seem to offer a "delete all contacts" function.
I would prefer to do this with stock GOS tools only.
Is there a set of files / a directory on the device that I can simply delete via the stock Files app?
