User Interface Design
“User Interface (UI) Design focuses on anticipating what users might need to do and ensuring that the interface has elements that are easy to access, understand, and use to facilitate those actions. UI brings together concepts from interaction design, visual design, and information architecture.”
“Users have become familiar with interface elements acting in a certain way, so try to be consistent and predictable in your choices and their layout. Doing so will help with task completion, efficiency, and satisfaction.”

Skype App
Skype is an application that provides video chat and voice call services. Users may exchange such digital documents as images, text, video and any others, and may transmit both text and video messages.
I recently got the idea to remove this app from my phone, because if I hadn’t used it for 180 days and didn’t use it to call or recharge, I would have been able to get the money out of my account, and I’d have to re-log on the computer to activate it, and I think it brings me trouble.

Recent versions have started harvesting your contact data to ‘suggest’ new contacts to your contacts in a ‘discover’ section that is presented ahead of their favourites. If you or they don’t have many contacts, it is often obvious where these suggestions are coming from, effectively disclosing your contact list to everyone on it. There are no permissions or controls you can influence on this. I think that will leak my privacy and the new version of the Skype let me very confused since of the design, I came in a page is as show in the picture:

If I am the designer, I will let the call page as the first page, just like the iPhone call page, because I do not want when I want make a phone call to communicate with others but I should find where I could make a phone call or video’s button for a long time.
