Not sure if it's the camera or just the sharing. When I click a picture, I don't see any issues in the picture. But when I share it, I see two main issues.
1. On the top right or the left corner, it seems like the pixels have been crunched into a small square.
2. Even though the pictures have been taken with the desired orientation, but while sharing, the orientation would change to a +/-90°.
Doesn't matter which app I share via, maybe WhatsApp or Instagram, these issues have been found.
