Android 手机上的应用程序显示问题：屏幕可见性有限

Question

问题： 应用程序仅显示在我屏幕的 10% 中，它显示在我的 Android 手机的一角。所有的屏幕都是这样产生的。该应用程序在 Windows 上完美运行。在 Windows 10 上运行时，该应用程序会显示在整个窗口中。我在 Google collab 上使用 buildozer 导出。

试过： 我尝试更改 kivy 版本，切换到其他屏幕，使用另一部手机，使用 kivymd 而不是 kivy 和 visversa[android 设备上的屏幕]()

我尝试更改 kivy 版本，切换到其他屏幕，使用另一部手机，使用 kivymd 而不是 kivy 和 visversa，导出一个显示全屏的更简单的应用程序

这是我的代码摘要
