On my old Note4 and S7 edge i used to be able to take 2 pictures at the same time with the front camera picture appearing on the combined as if it was a postage stamp. This was great for scenery and location shots, showing the detail plus showing a small selfie.
Have tried various downloads but can't get anything close. Nearest i have seen is the samsung tv advert where it half screens each camera, which seems rather pointless. Any suggestions or workarounds that don't need extensive post image processing?
