"Consistency and usability of the interface is very important for us. And that is what we are trying to improve from version to version. We first introduced the idea of a fully-virtual on-screen controls in Honeycomb. Surprised at what it has given the flexibility and adaptability of the interface. Whether you hold the device horizontally or vertically - the control buttons are always in a familiar and comfortable place to hand. Now in Jelly Bean also has virtual control buttons and a constant string status bar on all screens of the system. This is what we came after a study on usability in a variety of devices running Android and with different screen sizes. It was found that muscle memory plays a big role here. The users had to taste that the position of the controls and their sequences are the same, why can push their usual way, no ironing.
Smart phones are usually used in portrait mode, occasionally switching to landscape. And quite rare, and more precisely, almost never flipped upside down. But with the growth of the diagonals of modern devices, it usually starts to change more often. Imagine the disappointment when you take the tablet from the table, took it upside down, and now that they normally use to either reach for the control buttons in the strange place, or the same urgency to turn the device in their hands. Control buttons in Jelly Bean always remain in their usual places. And it does not depend on the size of the screen, if you did not get into the hands of the device, that there is simply physically impossible to fit all the controls. In other cases, the system will do everything automatically. The new control system in Jelly Bean itself is very well established. It was found that work with the device has now become equally convenient for both left-handers, and the rights and putting the gadget on a desk or lap, or by placing it on a stand or simply hold in one hand.
And, last but not less important - unifying the control layout, we were able to set the standard for the location of the other elements, such as notifications and quick settings.
" Matias also commented on Google's attempts to stop using the SD-card in devices running the green robot:
"Many people like the idea of using memory cards in smartphones and other mobile devices. But in fact, it creates problems. For example, if you save a photo or video or music on your device, you need to get the data? In the phone memory? A memory card? Should there be a dialogue with the users of the system each time with a choice? Or maybe somewhere in the settings must be the switch? And what happens if you have to remove the memory card? How to behave applications and widgets? How then to get access to the stored user information. Too difficult to immediately answer this question.
We decided to simplify the situation by giving the user a fixed, but a sufficient amount of internal memory, which is drained and all the information. Users now do not need to think about where and what to keep and how it will work in the future, what will happen if the SD-card suddenly fails. Buying any Nexus you know how much memory you will be available, so choose the model that suits your needs. This eliminates any confusion.
" And this comment, by the way, just in line with what we've heard once before from Dan Morrill. Whether you like it or not, but Google decided that simply do not want to ask too many questions the user about what and where to save. However, this position causes a wave of indignation, because many lack of storage space that we offer manufacturers. Especially when it comes to storing bulky video and other media content.
As you can see, even now, many vendors have adopted a new strategy of Google and let your gadgets without memory card slots or no hardware keyboard. However, some are still opposed to the legislator than sympathy with the specific range of users.
