In science fiction, smartphones are often depicted as highly advanced devices. They might have capabilities like instant holographic communication, being able to access any information in the universe, or even control complex machinery remotely. For example, in some sci - fi stories, a character can use their smartphone - like device to hack into an alien spaceship's security system just by a few taps on the screen.
One common feature is extreme durability. They can withstand harsh environments like the vacuum of space or the intense heat of a planet's core. Another is super - fast data transfer. They can download an entire library of alien knowledge in seconds.
Okay, I can use the following words to describe things that are very light:
Light as feather, light gauze, lightweight, light, light steps, light as a feather, light as a feather.
