Why keep spreading FUD? It's not like Tim Cook is going to reward you with cookies. Unlike iOS you don't have to be on the latest Android since it has much better backwards compatibility and better longevity since there's much less forced obsolescence such as 32-bit still supported in 2019 while iOS ended it in 2017. Here are examples of better Android OS backwards compatibility, longevity and just better apps ecosystem. So, about 5 to 9 years of Android backwards compatibility compared to obsolete 5 year old iOS devices like iPad Mini 2 & 3, iPhone 6, etc. You also overstate the backwards compatibility for iOS - all the new iOS goodness goes back to iPhone 6s and the iPad Air2. Those are several version back from the current phone.
ePSXe, one of the best Sony Playstation emulators is backwards compatible with Android 2.3 from 2010. Not available on iOS.

Sigh...... don't they teach reading comprehension in schools anymore???
Ok let me break down your post to prove your missing the point once again.
1.) First - Backwards compatibility is not meaningful to the fragmentation issue. If you read my points on fragmentation it was not that any android app was not backwards compatible. At all. My point was that because updates to the latest version of Android is SOOOOO uneven in the android user ecosystem - application developers can only implement new functionality present in older Android versions because the majority of the Android user base is 1-2 versions behind. So OF COURSE - I would expect backward compatibility - the problem is these applications will not be able to take advantage of all the new "features" that are in the latest version of Android. The latest numbers from Google itself shows that 61.3% are using Android Nougat or earlier version.
2.) Second - Because a lot of features that you pointed to were not in stock android but implemented by third parties - Android developers would not be able to take advantage of them because they would not be available in the broader user community.
3.) Third - you have some inaccuracies in your list of applications that "are not available for iOS".
ePSXe - Sony Playstation emulator - apparently there is a version.

Solid Explorer--- Ehhh it seems odd about how you argue that Android had great file management from the get go only to point out a third party app for file management as the Android "model" for file management. I went to the website and it didn't seem to do anything the stock iOS file manager doesn't do. Your lipstick on a pig argument is a nice opinion - but from what I objectively see it does not hold water. You also ignore the whole host of third party file manager apps that have been available for iOS for a while - many of them making the Solid Explorer look weak in comparison. (

Kodi - Well it appears you can put it on iOS for both the iPhone and iPad - however, since iOS has native media players that have been class leading since day one - not sure I need a third party application for playing videos, movies, or music. It Android doesn't have a good enough player in its stock form - it seems to be a weakness not a strength. (

Termux - Well it appears there is a Linux shell for iOS - iSH ---
https://ish.app. There is also an app called LibTerm (
https://apps.apple.com/us/app/libterm/id1380911705)that does the same thing. -- There is also an app called Termius (
https://apps.apple.com/gr/app/termius-ssh-client/id549039908) running an SSH shell on iOS. So it seems iOS is well handled here.
Maxima - looking at the link you provided this is not a native app but a port running on an emulator. So not sure if this really counts. Now iOS does have a NATIVE Algebra AND Calculus app that does the same thing - and its not a port or runs on an emulator. Its called PocketCAST for Mathematics. (
https://pocketcas.com) and it runs on Mac, iPhone, and iPad. But not for Android. Sorry.
FINALLY - Your argument that the Android app ecosystem is better than iOS by referencing emulated applications and no enterprise applications proves the weakness of the Android market. For example - you reference terminals and video game emulators. How about SalesForce apps, SAP apps, Microsoft Office, Adobe apps (like light room) -- these are apps that matter and they came out for iOS first and are updated more frequently than on Android - if they are on Android. Why do iOS developers make more money than Android developers? Why does the Apple App Store dominate Google Play in revenues???
Here is a case in point - Messages. Google is JUST NOW getting their arms around a decent native messages application.
That is not FUD those are numbers and facts. And you have not made any points to address those questions.
