There's a lot of infrastructure necessary to use our current smart phones and a sort of delicacy that comes from things like tablets and scanning devices.
For communicators, we have to remember that these things operate without cell towers being located every 500m and instead have subspace transmitters that have ranges of ~couple hundred thousand kilometers that seem to not need any calibration to find the thing they're transmitting to and permit secure transmissions. They also transmit faster than light, so unless we have some sort of quantum entanglement based phone in the next 50 years, I don't think they're likely to be viewed as anachronistic.
Same for tricorders. I mean the only weird thing is their small displays. Everything else about them is still sci-fi, from tracking life forms to scanning the material composition of the ground.
