No automatic rotate option box should keep the device screen orientation from rotating while using the barcode scanner, it should be in portrait view
Barcode scanner screen orientation rotates itself after ticking the "no automatic screen rotate" option box
Download the app form Fdroid
Run the app, open the settings, scroll down to the "No automatic rotate" option, tick the option box if it wasn't ticked
go back to the barcode scanner main menu, the screen will still rotate itself automatically
NB: My phone screen orientation is not in rotate screen mode
