I use this code to select multiple photos from gallery:
I noticed that not all devices can select several photos at once. On some you have to "hold your finger" to select multiple photos. But on some it is not possible at all. For example, my tablet is a samsung galaxy 4. Android 5.0.2. It is generally impossible to select several photos on it. Also the Samsung A50 phone. If “recent” is selected, it is possible to select several photos, but if you select a gallery, camera, then it is impossible to select several photos. Also on xiaomi mi 9t. If you select recent or gallery, then everything works fine, but if you select explorer, then multiple photo selection does not work.
Why is this happening? How can you make multiple photo selections work on all devices?
I am especially interested in the question with the Samsung, why can't you select a lot of photos on them in the standard gallery?

Sub Activity_Click
Dim i As Intent
i.Initialize("android.intent.action.GET_CONTENT", "")
i.PutExtra("android.intent.extra.ALLOW_MULTIPLE", True)
i.SetType("image/*")
StartActivityForResult(i)
End Sub
Sub ion_Event (MethodName As String, Args() As Object) As Object
'Args(0) = resultCode
'Args(1) = intent
Return Null
End Sub
Sub StartActivityForResult(i As Intent)
Dim jo As JavaObject = GetBA
ion = jo.CreateEvent("anywheresoftware.b4a.IOnActivityResult", "ion", Null)
jo.RunMethod("startActivityForResult", Array As Object(ion, i))
End Sub
Sub GetBA As Object
Dim jo As JavaObject
Dim cls As String = Me
cls = cls.SubString("class ".Length)
jo.InitializeStatic(cls)
Return jo.GetField("processBA")
