I have a Nexus 7 and an Ipad Mini, the Nexus is Brighter and small enough to fit on my panel, the Ipad I use on a kneepad which unfortunately means I have to deal with more due overhead glazing
I am at the stage of deciding which way works best for me, they both function well with the software.
I've never had either overheat, but my cockpit is a tad draughty

I choose Samsung Galaxy itablet 8 inch. Pleased with the product good battery life. Needs a shade to prevent reflections in sunny weather.

The Galaxy Tab has an 'Outdoor mode' (Settings -> Display -> Brightness) available to increase screen brightness. Works well with SkyDemon.

I don't agree with this.

I've had overheating problems on just about every Apple device I've owned (iPad 2, iPad Mini, iPad Pro x3). I've NEVER experienced any overheat problems on any Android device I've ever owned (too many to list -Currently on a OnePlus6T, Galaxy Tab S2 8 and Galaxy Tab Pro S).

You are missing my point. The Android kit WILL be overheating, itís just the OS doesnít care...Because Android has to look after so many flavours of harware, it doesnít have the deep hardware monitoring that Apples tightly integrated eco system has. Android simply doesnít care much what hardware itís sitting on, or if itís frying to death in a hot cockpit. It may still work, but the heat wonít be doing it any good... Apples heat monitoring might be conservative, but itís there for a good reason...

I should think that, if the Android machine _really_ overheats, something bad would happen to it. Edward tells us this has not occurred. So either the iOS things need more protection from overheating than Android stuff, or the protection is far out on the safe side. It must be said this might favour the device's long life - but who cares, in an apparatus that's not meant to last more than five years anyway?

Standard Apple reasoning.

Quite right, it may well fail, but not necessarily the first time it gets very hot.
Can you guarantee it will last the full five years?
And what if it finally falls over at the wrong moment...
My worry is always what damage the heat is doing to those big flat LiPo cells...
Some cheap Android devices may not have ANY thermal protection read by the OS.

iOS devices tend to run cooler than Android, but their protection systems are built with very conservative limits.
Think of it as a feature, not a fault...

Correct, it's a feature. It's called thermal protection...

It is a nice discussion, thanks for that!

Of course I cannot, and nobody can. For no kind of device, least of all the new-fangled "Hai-Tek"

And what if it finally falls over at the wrong moment...
That's an easy one: switch to plan B, all of us have a plan B at hand; some even have plan C and plan D. Great!

My worry is always what damage the heat is doing to those big flat LiPo cells...

That is the right kind of concern. But even mid-quality LiPo's have all kind of protection built into themselves. It should not be a concern of the host device. Beware, though, of low-cost so-called high performance Lithium batteries; especially from certain low-price sources/countries.

Negative: I know. But your definition of "mid-quality" may differ from mine, of course. Lack of certification of them batteries, perhaps. I totally agree that only a fool will install batteries from Ebay, Banggood &c in anything carried aloft.

. . . covering up poor design.

In their quest for form over function they built a product with inadequate ventilation/cooling & try to cover up by shutting it down. If anyone complains, they're told "they're using it wrong."

I can do 4 or 5 hour flights with my device plugged in & charging, with the screen turned up to maximum brightness & it barely gets warm.

Not really, Apple are renown for good thermal management in both their prtable and desktop devices.
If your Android is 'barely warm' then it isn't being fried in a greenhouse cockpit.
As I said, it's down to thermal risk management - Apple play it safe, it's easier for them to do it, whereas the Android market has its usual fragmentation problem.

Ask yourself why really there's only two players in the commercial and military EFB market.
iOS and Windows.
ie. USAF use 21,000 iPads. Delta use 10,000 Surfaces.
You won't find many Android tablets amongst the major players.
Two main reasons, security and, yes, thermal control...

Exactly this.

Security is the ONLY reason. It has nothing to do with thermal management. As above.

It has a lot to do with thermal management or rather lack of it in Android tablets...
Still, if that's what you want to believe and trust your nav to, go ahead...

Going back to the subject, rather than a iOS / Android willy waving contest.

I have to confess that, although I've considered one, I have never used an android device with SD as I'm sure, at the time I subscribed to SD, it was a 'lesser version' available on Android. It may have changed now, so happy to be corrected on that one!

I'm currently using my wife's old Ipad 2 cellular, which must be getting on for seven or eight years old, and it works fine - haven't experienced any overheating issues. Previously, I used an Ipad Mini with a Garmin Glo GPS, and it was the Glo which kept quitting due to overheating, as it usually sat on the coaming in full view of the sun. Popping it out of the sun for a couple of minutes revived it, though, and I found it worked just as well sitting on the back seat.

My point is - eventually - that there are loads of second hand ipad 2's about on online auction sites, which will be the same kind of money as a new Android tablet.
