Thank you very much for being so committed to fixe the issue!

I think in the short term, the pragmatic thing to do if you just need it to work now is to downgrade the project to the C2 runtime and publish with that.

Ok for the downgrade to C2 runtime. If it make it run on more devises, it will be great!

Few questions on it:

- Would it means any other implications to downgrade or all the game will work the same?

- When you say "to be removed in 2021", you mean not usable in Construct but the game will still work fine right?

EDIT: I can't go back to C2 runtime because of compatibility issues with BBCode, Speech synthesis plugin, wait for previous action, typpewritter, etc etc...

About the debugging test, I can try. However, the old phones are not mine (and I updated the only one I had) and in Africa so it's difficult to perform a complet test on them. I can bring devise information, system info etc but difficult to have more. I'll try my best anyway.

Hmm, just thinking - the device you updated from v71 to v80 and started working - what model device is that?

It's a Samsung note 3 SN900, so with indeed a Mali GPU, you're guessing right!

So what does it mean in pratical terms?

Also FYI it seems not working on a HUAWEI Y9 2019 with Android 9 (EMUI 9.0.1) and WebView 3.3.5.

When the WebView is out of date, it does show a message. It says "Software update needed" with instructions.

Actually one person told me that message was displayed but many didn't and it didn't show up on my old phone. And I guess if people are contacting me for help, it is not enough..

So I think we're back to square 1 - I doubt it's solely because of an old WebView version. There must be something else going on.

It's both a good news and a news, thanks for the help :)

But why would have the update of WebView made it work then? And what can I do find the issue (and the solution) if it not that?

That's is an Awesome idea developing an App to help people and families be aware of how to avoid Ebola, I hope goes well and that you can fix all the issues so they can make most of it, you never know how many lives you could save.

tarek2 thank you so much! We indeed truly believe this game can improve people health. It's our first big project (in partnership with Doctors Without Borders) and we are aiming to make more games on major environment, society and health issues. Hopefully with Construct if I can make sure the games can to use by everyone ;) here is our website (in French so far) for more info: pixelimpact.org

Thank you for your reply Ashley!

Are you sure it's to do with the webview version and not something else?

I’m no expert but I’m pretty confident it is the WebView because every time I update the Android System WebView on someone phone where before it wasn't working, it is now working.

For example, I have myself an old phone on which it wasn’t working (which a WebView version 71.0.3578.99). I updated WebView to 80.0.3987.119 and now it’s working fine.

So are you sure you are seeing this message?

There is no message, I was just saying it would be good to have the possibility to add a warning message with a link to update if WebView is out of date.

It's hard to imagine why this would not have been the case.

Unfortunately, people there have crappy phones and, as you said, try to save space and data so they don't keep their phones up to date.. Actually some people do the same in Europe so those cases occur more often then what I thought in the first place, especially for my target audience. And that why I really need a solution because I can’t tell myself every person to update their WebView…

So is there a way to either:

- Embedded/integrate the update of the Android System WebView within the game to automatically make it work?

And/or

- in case the WebView is out of date on the phone and the game doesn’t work, put a warning message saying something like “please update your phone by clicking this link” or so?

I'm keen to find out the reasons behind this, and would be grateful if you could shed some light on that.

I'll continue to collect data and share it with you as much as I can.

More customers asking in that issue might help

Thanks, I'll ask to Google myself to show support but it would be very nice and needed to have some possibilities from Construct because Google as being a big company might take some time..

Here is the link to my app in case you want to check for any other reasons it might not work on some phones: play.google.com/store/apps/details

Thank you dop2000 for your help (and sorry for the veryyy late answer, I was focusing on my android release :)

So actualy the solution you propose is kind to hard to put in place because I have a lot of text in a lot of different places and I'm not sure to understand how to make it automatic for everything...

I think the issue really comes from Safari. and it's not really a spacing issue because it looks very random.

I'm the only with this issue with BBCode and IOS?

Nepeo Thank you for the great explanations and sorry for the edditing of my previous post, I figured some things and I wanted not to overload the forum but I was to quick to edit :)

So just to be sure on the process :

I export my signed app with the signature I create > I upload my app on the Play Console > I upload my signature file there too if I want to have the Google Authentification and if I loose it, I can ask google another one (which will be quite the same process).

Any idea where I can upload the key to store it in the Play Console?

Because all I have is :

Also do I have to use a AAB and/or Android Studio to have the Google Signing? Because I would rather much not use Android Studio and export straigt from Construct.

(is a AAB really better or it's just a size matter? (my APK make 11mo and my AAB 10.5 so not much of a difference)

Thank again for the support !
