I've a problem with an upload image function from outsystems. When I tried to upload an image from smartphone's camera in portrait mode, it'd end up with an image that has been rotated counter-clockwise by 90 degrees. The problem is similar to what people have been asking on internet.

Perhaps someone had solved this problem and share with me on how to solve this? Thank you so much.
