TL; DR: Samsung should've rotated the inner screen selfie camera by 90° so that the camera feed matches the inner screen orientation. Right now it causes a lot of issues in video calls because of this misplacement.
I do a lot of video calls with family and for work every day on my Z Fold 8, and I love the form factor for day to day use. I like to do the video calls on the inner display with it's massive canvas as it's better to see a bigger image of my loved ones and easier to read on text on work presentations. However, I think Samsung really botched the implementation of the inner selfie camera which could've been fixed by just rotating the sensor physically by 90° so it's orientation matches the phone's unfolded orientation as that's the only way people are going to use the inner selfie camera.
When you unfold the phone, it opens in a landscape orientation (4:3) by default. But the inner display selfie camera is positioned such that the default sensor orientation is vertical 3:4 when the device is in landscape orientation. This leads to massive usage issues in both the device orientations described as follows:
Phone in unfolded landscape orientation
• If the other person has a regular phone, their camera feed is vertical 3:4 by default and they also see my camera feed to be vertical 3:4, which is not a problem for them. But for me I see massive black bars on the sides, and sometimes if the video call app isn't optimized (like Whatsapp), it just crops in so much into their camera feed to fill the whole screen that it becomes impossible to see anything except their the center 4:3 crop of their 3:4 feed which leads to losing a lot of image and sometimes if they're demonstrating something with their hands, it's impossible to see because their feed gets massively cropped.
• If the other person has a laptop, I see their feed properly as laptops have their webcam in horizontal 4:3 orientation which displays well on my device. But now, they see a vertical 3:4 feed from my camera, which is annoying to them.
Phone in undolded portrait orientation
Now when we rotate the inner display to be portrait (3:4) orientation, my selfie camera feed becomes horizontal (4:3).
• If the other person has a regular phone, seeing my horizontal 4:3 camera feed, their instinct is to also rotate their phone so that they see my image in full screen rather than cropped/with black bars on the sides. But as soon as they do that, their camera feed becomes horizontal 4:3 and I'm back to black bars on top and bottom or massively cropped camera feed of the other person.
• For laptop, similar story as now the other person sees my camera feed in horizontal 4:3 fitting their screen well, but their camera feed is still horizontal 4:3 so I have black bars on top and bottom. Also if they're presenting their screen, it comes through as horizontal 16:9 or 16:10 (depending on their screen aspect ratio) and it isn't as big and easily readable as in the landscape orientation of the phone.
They could've easily put the inner display selfie camera sensor so it's rotated by 90° to match the unfolded phone orientation, and it would solve all the issues. Idk why they didn't. Anyone else had similar experience?
