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.

I also vote for either a low-end iPad or second hand. There is not much sense in saving money with regards to flying on that level. C‘mon, we talk of investing the equivalent of two hours of flight.

Btw, after ForeFlight started offering AirMillion charts from today on, Skydemon turns now 95 percent dead for me. I was using Skydemon along ForeFlight for a couple of month, to compare and be ready to jump on the next train. I really like the more professional feel of ForeFlight and suspect this will even improve under Boeing supervision. Skydemons clear VFR charts compared to FF ugly homebrew kept me until today. As of today, for me SD only serves to check graphical Notam, once that is available in FF I am 100 percent out.

Another reason to choose iOS: staying ahead of innovation progress.

This thread has been very useful...

Iím an Apple person of at least a decade, with many workstations, laptops, iPads and iPhones in the house.

But I wanted a dedicated device bigger than my iPhone 8 for flying, and none of my current ipads have GPS. My default would be an iPad but frankly I just think the prices are getting crazy and resent having to get a cellular one to use gps. I thought about a Bluetooth gps unit like Garmin Glo, which I could have used with a full size recent iPad or very old mini 1. But that means more devices to charge and remember.
Iíd been watching a few iPad mini 3&4 on eBay but they still go for £250+ with no warranty and no idea of their past lives. £500+ new seems a waste for something I want to live in my flightbag and not have too many apps on. In fact I donít want the temptation of all my usual Apps.

Im not that familiar with Android (used one device briefly years ago), but ultimately decided it would be worth keeping an open mind and trying it - so based on some comments on this forum and others, plumped for a Huawei M3 lite (8 inch) which was reduced to £140 new and has GPS, good screen and battery life.

Not used it in the air yet but first impressions are encouraging. Mostly Iím just getting used to Android to try and get as familiar as possible and learn how to shut everything off I donít need and make sure I can move around it. Skydemon itself seems pretty good, the biggest thing that hits you initially is that it refreshes significantly slower - panning around in planning is much less smooth than on Ios (phone and ipad) , not sure if this is device or code or bit of both. Also Iíd prefer if aircraft and waypoints would just stay in sync between devices, but thatís not an Android/iOS thing.

The rest will report back as I go. Iíll have the iPhone on a ram sucker mount and the m3 on my knee board (ordered a simple silicone case and used two strips of Velcro to hold to the interior knee board so can still close lid and use paper - for now).

No idea what the Android equivalent to iOS location services Ďalwaysí is. Any tips for that and any other Android things would be much appreciated!

Hope to fly with it this week so will add some more comments down the line.

A bit late to all this. I've just finished my PPL and wanted to share my experience in this regard. The Flying School that saw me through my training has many planes, each of which has a dedicated, charged iPad. On a cross-country recently, the iPad overheated mid-flight and shut down. It was a very hot day and had been lying on the seat. Trouble is, this had also been running PilotAware. So, suddenly and WITHOUT WARNING, that key source of information was lost. Fortunately, my personal Android tablet (Samsung), positioned right alongside, carried on doing its thing. My Android phone, on a suction thing in the windscreen, carried on doing its thing. I was actually navigating using a CAA chart with the route plotted, but I am glad I wasn't reliant on the iPad.

When I landed back at base and reported the issue with the iPad, I was told they'd seen this issue, albeit rarely, on other iPads on the fleet.
