I have Samsung A35 by knoxx which ensures security but yet I see a difference. Whatsapp application can delete a photo from my gallery. The application has an authority to delete the picture from my own mobile. I guess this is the one of the biggest bug which contradicts the statement of Samsung security
I would suggest you to check the WhatsApp setting that you may be off to show images in your gallery in that case you won't be able to see your photos in your gallery.
Whatsapp can only delete their photos, not the photos from any other source, Knox security says any other information won't leak without your permission And also it is with autoblocker related
