Help Difficult to change screen viewing orientation

[mimitam]

I am having a real hard time to get my Galaxy tab 2 10.1 to rotate to the Portrait viewing screen orientation. Since Landscape is the default, it reverts back to Landscape every so often and it always starts out from Landscape.

Two questions:

1) How can I set the default viewing orientation to Portrait if do-able?
2) Why does not the orientation change after numerous flipping and rotating of the screen (I did it at different speeds, nothing helped)? Why is it not responsive to my flipping? The performance is just not quite acceptable in this area.

Any ideas, anyone?

Thanks...Mimi

Is screen rotation activated in settings? The tab is actually very sensitive

Yes, screen rotation is activated. My tab 2 10.1 has real delayed reaction if there's any after I try to rotate the screen no matter which direction.

Do you think I might have a defective machine?

Thanks...Mimi

Mine starts from the orientation it was in, when last shut down or the screen timed out in. There is very little delay.Probably not more than 0.5 of a second
