I have a new iPhone 6+ 128Gb and have been using it for a week. I never restore from backup with a new phone so I upgraded iOS, reseted it to factory defaults and started from scratch. After installing all my apps again and setting the phone up I have noticed that the Messages app has an orientation problem. It just happens when using the NEW MESSAGE button: 1. Hold your iPhone in portrait orientation and open the Messages app. Be sure to check that the orientation lock is not enabled on control center. 2. Tap the NEW MESSAGE button 3. When the new message screen shows rotate the iPhone to landscape mode. Mine does not rotate the screen. The screen continues locked on portrait. This DOES NOT happen when I am answering to an already started Messages conversation. In this case the iPhone behaves as expected and the screen rotates normally. Has anyone seen this? Does a settings reset help? I really don't want to reset anything if I can avoid it, but maybe I am going to have to. Thanks for any help.
