Use SMM to load the image. It will automatically handle the exif orientation setting.

[B4X] SimpleMediaManager (SMM) - framework for images, videos and more

This is a simple to use, cross platform library, that does many complex things under the hood. The developer calls SetMedia with a placeholder panel and a url. The panel will show an image, video or animated gif (more formats will be added). 'Show a remote image / video / animated gif in...

What i mean is that when i take a picture using CamEx2 It will produce a data as byte. The problem is the image in that byte is already rotated and not the imageview causing it to rotate. How can i resolve wherein the produced byte is always in portrait orientation at all devices?

B4X: 
Sub TakePicture
    Try
        SetState(openstate, True, VideoMode)
        Wait For(cam.FocusAndTakePicture(MyTaskIndex)) Complete (Data() As Byte)
        SetState(openstate, False, VideoMode)
        cam.DataToFile(Data, VideoFileDir, "1.jpg")
        imgbyte = Data
        Dim bmp As B4XBitmap = cam.DataToBitmap(Data)
    Catch
        HandleError(LastException)
    End Try
    
End Sub

It happens when the camera creates a jpeg image where the image itself is rotated and the correct orientation is set in the exif headers.
SMM will load the images correctly, unlike LoadBitmap which ignores the headers.
