Phones have multiple lenses and sensors, but they don't have multiple sets of sensor readout capacity. Even when the theoretical maximum pixel througput (as in biggest sensor the SoC can be paired with) is big enough on paper to do all sensors in a time division multiplex, I wouldn't be surprised if the switch wasn't fast enough.
(personally I'd love to have a camera app that did all-lens release for stills, I'm of the "beyond point-and-shoot" school of photography, shoot without much pointing, sort them out later)
