Qmlreddit is fully usable
FrontView is fully usable
Mbarcode is fully usable
Qtirreco is semi usable only half of the screen is viewable, considering the narrow fov and location of the ir port port it doesnt really make sense to have a portrait mode
Evernote is semi usable folder contents are cut off
Gonvert is semi usable some text is cut off

It should be noted that the image viewer in full screen works fine in portrait mode if the phone is upside down, earpiece down
