The Galaxy Fold isn't the only crazy phone Samsung has released - here are some of its wildest devices from over the years

Curved screens have become a staple of Samsung’s latest flagship phones, and it all started in 2013 with the Galaxy Round. The device’s screen had a concave curve that was meant to make the phone more comfortable to hold up to your ear and in your hand. Samsung launched the phone in Korea in October 2013.

Even in the era of the smartphone, Samsung hasn’t given up on flip phones. The Samsung Galaxy Golden, which the company launched in 2013 according to tech website Gadgets 360, appears to be a smartphone squeezed into a flip-phone form factor. It had two 3.7-inch touch screens: one on the front of the phone’s clamshell cover and one on the inside.

Like many cell phones of its time, the Samsung Reclaim had a slide-out keyboard. What made this phone stand out was its eco-friendly design, constructed from recycled plastic, and packaging made from recycled paper, as CNET notes in its review from 2009. That and its bright green color of course.

The Galaxy S4 Zoom is yet another hybrid device released by Samsung in recent years. As its name implies, the Galaxy S4 Zoom is a smartphone camera mash-up that supported a 10X optical zoom. It essentially looked like a Galaxy S4 with a camera stuck to its back. Samsung released the phone as an additional variant of the Galaxy S4 in 2013.

Samsung's Beat DJ wasn't just designed for listening to music — it was made for DJ-ing too, apparently. The oddly-shaped phone included a DJ app that made it possible to "scratch" a track by pressing the middle of the screen. It appeared to be a flop though, as CNET said the app would be "the most unused feature of all time" in its review from 2009. It also included Bang & Olufsen audio.

The Bang & Olufsen Serene may be one of the most oddly-designed phones in history. The audio company partnered with Samsung on the device, which was being marketed as a luxury gadget for audiophiles. It had a distinguished trapezoid shape and a rotary style keyboard and was priced at $1,275 unlocked when it launched, according to CNET's review from 2006. But it wasn't very practical, as the review notes that a screwdriver was required to access the battery and SIM card.

When it comes to Samsung's SPH-N270, the appeal is in its novelty. The phone is probably only recognizable to those who have seen "The Matrix Reloaded," considering Samsung released this phone in 2003 to coincide with the movie's launch and didn't market it much beyond that, according to PhoneArena. Samsung is said to have only produced a limited number of units, making it a rare find today that can sell for as much as $600 on eBay.
