On a button click, a popup appears where I should enter the nam

    Ok, fixed it, my fault I guess.

    It seems Keyboard and UIViewController call supportedInterfaceOrientations separately and rotate based on its return value. I had an if-else statement in there and was returning AllButUpsideDown only in some cases. When keyboard checked whether it was supposed to rotate method returned Portrait, and for viewcontroller value was AllButUpsideDown.

    So I changed this:

    public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
        {
            if (someStatement)
            {
                return UIInterfaceOrientationMask.AllButUpsideDown;
            }
            return UIInterfaceOrientationMask.Portrait;
        }
    

    To this:

        public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
        {
            return UIInterfaceOrientationMask.AllButUpsideDown;
        }
    

    And now only ShouldAutoRotate decides whether it rotation should happen or not.

    To some up it should look like this:

    public override bool ShouldAutorotate()
        {
            if (someStatement)
            {
                return true;
            }
            return false;
        }
    
        public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
        {
            return UIInterfaceOrientationMask.AllButUpsideDown;
        }
