How to change the size of MAUI Shell back button? For improved use when using tablets with gloves

[TomRoberts97]

Hello :)
I am working on a team developing a MAUI app for engineers. Many of our users have suggested enlarging the back button for better use with gloves.

Image shows code in AppShell.xaml and no change when running app in Android emulator. IconCamera is a random camera font awesome icon which works perfectly well in other places in app.

In my AppShell.xaml I have attempted to use Shell.BackButtonBehaviour and IconOverride to hopefully use and size a custom button but have had no luck. Code shown below

<Shell.BackButtonBehavior>

<BackButtonBehavior.IconOverride>

</BackButtonBehavior.IconOverride>

</Shell.BackButtonBehavior>

I only managed to change the icon when setting Shell.BackButtonBehaviour and IconOverride in a specific ContentPage .xaml file. The icon changed to my font awesome icon but the size did not seem adjustable.

Could anyone help with this?

Android is our main platform for use, so just achieving this on Android would be amazing!

Thank you in advance
Tom :)
