Landscape rotating problem

[Sawsan96]

Hello, i am facing a problem in rotation with my Z1.
My phone seems whenever I open facebook and rotate my phone while I am on the portrait mode it turns to landscape.
What happened and I really don't like it!! Its bothering me and pretty much annoying
Can anyone please tell me what should I do to keep it in portrait mode?
Thanks!

@Sawsan96 You should have auto rotation in quick settings. Just set it to portrait alone.

Let me see if I understand this, are you saying that you rotate your phone from portrait to landscape and you want to the facebook app to remain in portrait mode?
