Treating it as retail consumer electronics shit isn't rugged enough for real use.
But it is retail consumer electronics and it should be able to handle temperatures commonly encountered for a retail electronics satellite dish, which includes a hot roof in Arizona, but does not include the back of a hot truck where a consumer shouldn't expect his home dish to operate.
Either this was a dumb oversight, or it was an intentionally cut corner because of schedule or MVP or something.
However, since most phones are relative water resistant now, a good option is to use evaporative effects to cool them down. You could also dig a hole in the earth to find cooler temps and dissipate heat that way.
You can find same chips (=same function) made for consumer electronics, automative, aeronautic and military, all with different temperature and humidity ranges. I'm not sure about mobile phone CPUs/SoCs, but automotive equipment is a lot more resilient to voltage spikes well above the normal 12-14V.
Fortunately, I had seen this before in undergraduate physics lab, the day our LCD experiment was interrupted by the room thermostat breaking, sending the temp > 100F. The nice thing about LCDs is that the crystals reform when it cools. All you have to do is wait. Probably works for most modern phone displays.
