Xamarin - support inserting GIF and images using Android keyboard

Has anyone gotten the android keyboard to support GIF and image insertion in an Xamarin app? Let's say I want to build a chat application, have a custom EditText view to capture user input, and want to have it behave similar to the Android built-in chat application. Currently the keyboard shows a popup . Is it possible to make this work? I prefer to not create a custom keyboard renderer, though was hoping this could be done within a custom EditText renderer. Along the lines of:
UPDATE: For anyone looking for a similar solution, I have been making progress using the https://github.com/xamarin/monodroid-samples/tree/main/android-n/CommitContentSample. Essentially set the content mime types and wrap the IOnCommitContentListener, then process OnCommitContent().

Xamarin Forms - physical keyboard dims page when no input control is present

My actual application is using a bluetooth scanner in HID mode and capturing the input on the DispatchKeyEvent of the MainActivity. It works great except that the screens dims to some dark opaque color where it looks like everything is disabled and you have to navigate back to a page with an input control and tap on it to get the screen to go back to normal.
It's not as noticeable in the stock template but in my actual application (Screen shots at bottom) the dimming is very noticeable; it's a blue-gray opaque overlay that really stands out. I have no idea why it's like that. I'd almost just be happy if my actual app dimmed like the default forms sample.
Steps:
Make a Xamarin Forms app from one of the templates.
Change nothing.
Run simulator.
Press a button on your keyboard.
Result:
The screen dims and the soft keyboard does not popup.
Next Steps:
Add an Entry control. < Entry/> will do.
Click on it and the screen brightens back up.
Delete < Entry/>
Press a key on your keyboard and the soft keyboard pops up and the screen doesn't dim again.
What I want:
To know where the dim/overlay color/opacity is set so I can change it.
To not allow the soft keyboard to try and popup at all unless there's an entry field that has focus.
Here's screenshots from the default forms app:

My actual test device is a Samsung Galaxy XCover Pro running Android 10.0. I'm working on porting a native Xamarin Android app to Forms so we can run it on iOS as well. I never had this issue with my android app and I'm not sure how to track down what's happening.
Here's a before pic. I've got an Entry field focused.
After scanning a barcode with my bluetooth scanner this happens:
There is NOT any overlay/modal boxview defined in the XAML. The overlay is nothing that I added. Though I seem to have done something to influence the color; I don't see anything in my styles.xml files that would change the color from the default light gray (as shown in the sample Xamrin Forms template).
I can reproduce this with a scanner on the "Welcome to Xamaring Forms!" as well, the screenshots don't really show the change in overlay color; its much more subtle; I really would like to know why in my app the overlay is so much more obvious.
I'm still annoyed it happens at all. But just in case anyone else using a
hardware keyboard as input (or a BT scanner connected as a HID) and you thought you'd be fancy and override one of the default styles and use a pretty green accent color like this: (though stupidOverlayColor has been changed to pink just to make sure I found the issue) - don't do it.
<!-- Base theme applied regardless of API level -->
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorControlHighlight">#color/stupidOverlayColor</item>
</style>
The moral of the story is that "colorControlHighlight" is evil and not to be overridden and used with hardware keyboards, unless you want your app to think the entire screen should get the highlight color after you scan a barcode like this:

Xamarin.Forms Shell Tabbar goes up when keyboard open in Android and iOS

Xamarin.Forms UWP Application doesn't work on XBOX as native

I have tried my UWP app on XBOX one which is built using xamarin.forms and it works generally fine but by default mouse mode is active. I changed it using
RequiresPointerMode = Windows.UI.Xaml.ApplicationRequiresPointerMode.WhenRequested;
on UWP level in app.xaml.cs and it disabled mouse pointer but problem is that using game pad, i am not able to select items on the UI. I can navigate through textbox and buttons but not Toolbar (Commandbar in uwp), ListView, Masterdetail, Tabs etc.
I created a blank native UWP application and added a commandbar with AppBarButtons and NavigationView with NavigationViewItems. It perfectly works, I am able to navigate between menu items and commanbaritems using mouse pad.
Why this is not working for Xamarin.Forms? is xamarin.forms not actually native for UWP?
Xamarin.Forms MasterDetailPage was written before NavigationView existed and it doesn't use it at all (and especially not with NavigationViewItems, that would limit the flexibility, i don't think it will ever be used).
As SplitView has some focus bug that I can confirm it doesn't come as a surprise that it doesn't work with XBox as expected. However UWP doesn't grant that the app will work properly when you disable the mouse mode with native controls, that's why it is enabled by default. There are properties like XYFocusLeft that must be set if the app is not working properly. You probably need to make custom renderer to expose those properties and set them right. That's pretty much of work to do but it is up to you to decide...

How to navigate using DPad in Xamarin?

The Android device I am using does not have any touchscreen. All it has is a touch pad that can generate KEYCODE_DPAD_UP, KEYCODE_DPAD_DOWN, etc. It appears, by default, a Xamarin-based app ignores these key codes. I am wondering if there is some way to map these key codes into navigating among the displayed controls. Regards.
