Here’s a conceptual design that we haven’t seen before. The DYA phone concept has materialized from the future, with some interesting futuristic features. For one thing it’s got rounded bubble-type buttons that are easy to press, without having to look at them.
In back it’s coated with elastic paint that makes it pleasant to touch and reduces the chances that it will be damaged when dropped. Strangest of all, and maybe the coolest feature is the diagonal cut that makes it compact when not in use, but at the same time large enough to be used comfortably when you open it up to make or receive a call.
