In the email app, the trash can switches from left to right depending whether you're looking at a message list or an individual message.
If you start to compose an email and abandon it, "OK" is on the right and "Cancel" is on the left - the opposite of how it used to be, and of every other software I've ever seen.
When answering the phone, the position of red and green buttons is reversed depending whether the screen is locked when the call comes in.
No consistency at all. What gives?
