Foldable phones

Folding form factor

— this category includes both the classic flip phones and the trendy smartphones with foldable Flip screens.

In flip phones, the body consists of two halves that open like a clamshell when in use. The main screen is located on the upper half, and the keyboard is on the lower half. The design may also include a small external screen that allows you to see important information (such as the caller's number) without opening the phone.

The flip format has regained popularity with the advent of smartphones equipped with screens that fold vertically. When folded, they resemble a compact women's powder case and take up minimal space; when unfolded, they transform into a regular smartphone with a slightly elongated screen. For convenience, Flip phones often feature an additional external screen for use when closed.
