I have the same problem.
Call Rho::Camera in ET1 by RhoMobile 5.1.1.
The image on screen is rotated by 90 degrees.
How to fix it?
This is a known issue on some devices, as you can read on the Camera API doc (5.1.1)
This is a base 64 encoding of the image and can be used to easily embed the image on the page or store the image in a database. On some consumer devices, captured image will be rotated 90 degrees while displaying.
