Foldable or flip phones are being developed by several mobile companies.

When it comes to design, be it iPhone or any other smartphone, the structure of all is always the same i.e. rectangle.

Even today, the world is dominated by smartphones with such designs, which have rounded corners and many people have asked the question, why is the smartphone’s structure rectangular?

One of the reasons why a smartphone has a rectangular structure is its display, as this is the way smartphones have been screened since they were invented.

Another reason is that long and thin rectangular phones can easily be placed in a pocket or bag.

Another reason is that our hands have a firmer grip on these devices thanks to the rectangular design.

Also, the battery inside the phone is thin and rectangular.

This is the reason why this design of smartphones is unlikely to change in the coming years.
