[FONT="Franklin Gothic Medium"][FONT="System"]Guys, for those of you who have that nasty "no red reject button" problem.
Actual problem is not with landscape orientation of the incoming call screen, it works fine (two buttons are there one after another). The problem occur then you set phone app to portrait mode. Upon receiving call the screen is not displayed as a portrait, it only show big green "answer" button and only thin red line below it. This deformed display is not genuine landscape, but rather deformed portrait.
Once again, landscape orientation works fine, the problem is with deformed display of portrait orientation. However, if you leave the device showing the list of recent calls in portrait mode you new incoming call will be shown in perfect portrait. Strange, huh? But if you leave it at the desktop new incoming call is displayed wrong (no red button).

Now, the fixing of this one. Unfortunately, I didn't manage to fix it. I've tried everything already:
1. phone_ui and rtcom-call-ui in blacklist of transitions.ini
2. ui_can_rotate command (true and false)
3. desktop_orientation_lock (true and false)

As of now, I don't see the way to fix it, so using landscape orientation of the phone app.
