Unexpected behaviours after a screen orientation change (reported by activity)

[datalossdetector]

I developed an automatic test case generation tool and it detected these problems in your app. I would like to know if you consider them as failures and, if not, why. Thanks for your collaboration.

1) When I change the orientation of the device screen, MessageList activity changes its state. Below there are four different examples: the screenshots were taken before and after the screen orientation change and they are paired (before, after), (before, after) ...

--- first case ---

A Dialog disappears when the device screen is rotated.

--- second case ---

The scroll position changes after an orientation change.

--- third case ---

Text "test123" disappears from the search bar.

--- fourth case ---

The dialog disappears from the screen.

2) When I change the orientation of the device screen, MessageCompose activity changes its state. Below there are two different examples: the screenshots were taken before and after the screen orientation change and they are paired (before, after), (before, after)

--- first case ---

--- second case ---

The image icon appears after an orientation change.

3) When I change the orientation of the device screen, in ManageIdentities activity, the Dialog widget "Manage Identity" disappears.

4) FolderList activity, when I change the orientation of the device screen, changes its state. Below there are two different examples: the screenshots were taken before and after the screen orientation change and they are paired (before, after), (before, after)

--- first case ---

Text "test123" disappears from the search bar.

--- second case ---

A Dialog disappears after an orientation change.

Yes, I consider those to be bugs.

On all of my Xperia Z3c/Z5c K-9 crashed sometimes, not reproducibly, but all the more annoyingly on screen orientation change.
