 * The touch screen doesn`t work sometimes, when clicking on “Add a contact”.
+* Most elements inside ChatSecure are clickable. For example the status button or the current status message. The name of the chat partner is underlined. For the first time I have thought it is clickable and tried it. This means I expected a reaction on my click, like the other interface elements would do. Later a figured out that this marks the current chat-tab.
+* If you open up the context menu you will see an exit button at the bottom. In my opinion this should not be there. Instead this functionality should be provided by the home button.
+* The settings menu is hidden behind the three points. Today most mobile device users expect some kind of gear-wheel or screw-wrench. Maybe it would be better to change the three points into something like that. If the three points are a place-holder for an collection of options it should be more clear what is meant with this symbol.

+* The explanation of the dialog says you should enter the email address of the person you would add. This could my be confusing because people could think they could add all people with an email address.
+* If one accidentally touches the area outside the dialog box the process of adding a contact is stopped. The annoying point is that one has to type in the data again if you want to add the contact.

+* I didn`t understand the box that plopped out, when I wanted to import the OTR keystore. (And don`t know what it is for, by the way.) It was only open for a few seconds, so I couldn`t read all of it. After I read it 3 times, I still didn`t found this file, the window wanted to lead me to.

 * In the top status bar of the phone, a corresponding icon is displayed in case of a new message. This icon is useful if the app is not open yet. However, the Chat Secure icon is also shown in the status bar permanently if the app is running. That means if you get a message you have 2 icons of Chat Secure in the status bar. Will there be more icons of WhatsApp etc. the bar will be full very quickly. Therefore the always visible Chat Secure icon should be removed.
+* After typing in the name in the contact box, I wanted to click on “invite”. For that I clicked in the red box below, because I intuitively thought, I would come to the interface before. Maybe it is better to place the “invite”-button somewhere in the red box, because you won`t have to click the keypad away then.

 == Help users recognize, diagnose, and recover from errors ==
 * I have not received any error message from the app. Therefore, no statement about the intelligibility of the message and the quality of the solution paths are taken.
+* Error messages very technical and not saying in former versions. Details are fine if one knows how to deal with, but it would be better to give a description of the problem and add an detail Button to see the exact problem.
 == Help and dokumentation ==
-* A help is not available in the menu. This would be very helpful for "beginners". E.g. the traffic light system for the security of the message isn’t immediately clear.
+* A help is not available in the menu. This would be very helpful for "beginners". E.g. the traffic light system for the security of the message isn’t immediately clear. It would be nice to have a short tutorial explaining the background for the user. This should easily explain what is OTR, what is a fingerprint and maybe some reasons why one should use the encryption. It could also ne nice to have a short Q/A part where some basic questions like 'Where did i find ...' or 'Is this possible ...' are answered.
