Almost all things need to be conceived by a person before they are created. Its much easier to conceive something than build it. Thus most objects will be written about before they exist. More emergent properties are less likely to have been predicted by fiction authors. Say the decline of good news sources due to the capture of most classified revenue by Craigslist and all the knock-on effects of that.

A large portion of tech is conceivable way before it is possible. E.g. self-driving cars and sentient AI robots have been written about for a century already. Doesn't really mean research into those is inspired by the stories.

Inspired by or surfing similar waves of thought. Science fiction can just go further ahead, not bounded by the realities of science and production limitations.

Sci-fi (and all fiction) are really just the author talking about the present. As such, all the sci-fi tech is just a neat description of an existing problem. Inevitably engineers will strive to solve those problems.

But a communicator is primarily a voice communication device. If I were to say a cellphone is like a star trek device, I'd say it's more like an undersized PADD

(and yeah, I maybe agree that the Apple engineers may have a lot of TNG. The 'too lazy to make actual buttons' set designers, I think, actually inspired apple; it really is a lot easier to design a muti-use interface if the "buttons" are all behind a glass touchscreen.)
