Android Question Opaque on Samsung but not Huawei

[GEoffT]

The first image shows the screen before the following code is obeyed.

The second shows the difference between Samsung S4 and Huawei phones.

As can be seen the underlying buttons show through on the Huawei but not on the Samsung. I can't find out why.....can anyone explain this please.

Sub btnAddScore_Click
    et10s.Color= Colors.white
    etScore.Color = Colors.White
    etXs.Color = Colors.White
    etHits.color = Colors.White
   
    pnlAddScore.BringToFront
    pnlAddScore.Visible = True
    pnlAddScore.Enabled = True

    dpDate.AddToActivity(pnlAddScore,lblDate)
    Main.bowType=""
    spSetOfRounds.Visible=True
    spAddScore.Visible=False
    spBowType.SelectedIndex = 0
End Sub
