"Smartphone users in general are unsatisfied with the existing AI features as the survey recorded 73% of Apple Intelligence users and 87% of Galaxy AI users stating the new features to be either ‘not very valuable’ or they ‘add little to no value’ to their smartphone experience."
This could be read as 27% of users, who have tried a brand new way of interacting with their phone, found it useful to some degree right away. Imagine: You introduce a brand new, well, anything into peoples lives at Apple scale, and 27% of them find it useful, right away.
I don't know what number people expect, but I think you could consider this an outrageous success. I am not saying it should be read that way. But then again, I am not sure why it should be read any other way.
