I've done some work integrating iOS and Android tablets into miltary environments.
the reason iPads occasionally shut down in heat is because they are properly prtected with thermocouples and firmware which monitors them.
Some Android devices will kepp going in the heat, but damage may be being done.
As stated above, keep ALL electronic devices out of direct sun in a cockpit..
A cheap Chines Android would do the job just as well, the money you save can be spent on flying. You pay a lot to Apple for less hardware and the image.
Apples hardware is top notch, unlike some of the cheap Android offerings.
It might appear to be about image, it isn't...
