I tested the code below on Samsung without any glitch, but on the Huawei P Smart, I get an error.

On the Samsung tablet, the folder com.bujardet.checkprinterfree is created automatically. On the Huawei, it is nowhere to be seen.

Should I try to create it ?

I will appreciate any help.

B4X:
        If File.ExternalWritable Then
            Dim content As String = "<html><body>" & Html.Replace("LetterSave:","") & "</body></html>"
            File.WriteString(File.DirDefaultExternal, LetterSaveFilename, content)
            Log("Saved " & LetterSaveFilename)
        Else
            Log("Could not save " & LetterSaveFilename)
        End If
Here is the error I get:
