WRITE_EXTERNAL_STORAGE权限

Question

Based on google docs beginning with Android 4.4 (API level 19) Android apps doesn't need WRITE_EXTERNAL_STORAGE Permission to write to its own application-specific directories. 基于从Android 4.4（API级别19）开始的Google文档，Android应用不需要WRITE_EXTERNAL_STORAGE权限即可写入其自己的应用特定目录。 uses-permission 使用许可

So I removed this permission for API 19: 因此，我删除了API 19的此权限：

<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"
    android:maxSdkVersion="18" />

But after publishing app, we find out some android devices(not all of them) with API > 18 have problem and app can't write to it's own application-specific directories. 但是在发布应用程序后，我们发现API> 18的某些Android设备（并非全部）存在问题，并且应用程序无法写入其自己的应用程序特定目录。 I remove android:maxSdkVersion and published app again and problem solved. 我删除了android：maxSdkVersion并再次发布了应用程序，问题已解决。

How is that possible? 那怎么可能？ And what I should do to remove this permission and my app work in all devices? 我应该怎么做才能删除此权限，并且我的应用程序可以在所有设备上正常工作？
