Ask HN: What health features can be designed into next generation mobile phones?

The current coronavirus crisis shows a big gap between health monitoring, screening, and testing ability in many countries.

This is a gap that should be addressed in new mobile products. Some ideas:

* Adding a contactless IR thermometer lens to a phone is an obvious idea, since it is needed everywhere and is cheap to implement.

* Ultrasound scope and microscope, designed as mobile accessories, can help to provide telemedicine consultation and reduce hospital jams.

* A kind of phone-based "mobile blackbox" similar to flight blackboxes, can be used to speed up contact tracing of patients.

What other innovations can you suggest to incorporate into next year's mobile technology, to help the world deal with pandemic and health care deficit?
