Soft keyboard disappearing in Android app

I have this problem with many users, I found a page about this and I tried several published functions but the problem persists.

Any solution for this?

With the information available I can't really say for certain what the issue is but I can share knowledge that can potentially help pinpoint the root issue.

Based on the animated gif, it definitely looks like the input is losing focus, just after the window is resized. On Android the document "window" is resized when the soft keyboard opens matching the new size of the view port. This is part of adjustResize behaviour.

adjustResize vs adjustPan

adjustPan is another configuration which causes the native view to pan instead of resizing. This means the view will not change in height to make room for the keyboard, and instead the entire view will pan. The view is not scrollable with this mode, so it can hide content (whereas adjustResize gives developers the flexibility of creating scrollable views). If adjustPan does solve the issue, it just simply highlights that the application is resetting focus when it shouldn't, either on window resize or orientation change.

These are native configurations, which can should be editable via <edit-config> directive. I wouldn't call using adjustPan a solution, but depending on your use case it could be something that is "good enough".

Node replacement

If you're swapping nodes which some frameworks like (ReactJS) might do depending on how the application is doing it's rendering, it might cause the behaviour you're seeing. If you're using any UI frameworks like ReactJS, or Angular, etc... review their documentation to ensure that they manipulate existing nodes rather than a complete replacement. Replacing nodes will cause nodes to lose their focus.

With adjustPan the problem persists. The only thing I think it could be is the phonegap-plugin-mobile-accessibility plugin.

window.MobileAccessibility.usePreferredTextZoom(false);

I'll try to uninstall it and let you know.

Thanks

The problem has not been solved yet. I am looking and trying to clean up. The problem I have is that it happens to users and I do not have access to the mobile to detect what is causing it. Thanks

The problem was found on Samsung and Xiaomi devices. On Samsung, after updating to ONE UI 6.1, this problem occurs and they recommend resetting or reinstalling the keyboard and, as a last option, resetting the phone to factory mode. The same for Xiaomi.

Thanks
