I gotta hand it to LG. The company doesn’t always hit its mark, but it’s always doing new things with its phones that no one else tries. From its audiophile-friendly headphone jack to its modular G5, the company has run the gamut of unique ideas. Its latest venture: a phone with a detachable second screen.

Cnet reports one of LG’s upcoming flagship phones – to be announced at Mobile World Congress in February – will be compatible with an optional “case with a screen.” This screen would potentially double the phone’s screen size.
