To be fair, designing such a small thing with cooling for this kind of temperature is really hard. You'd actually need active cooling, because otherwise you'd be too susceptible to colder temperatures, and even then the sun would quickly bleach out all components - assuming you'd even see something on the screen to begin with. Not designing your phone to run under the direct sun is IMO a reasonable trade-off.
