The Galaxy Round is Samsung's attempt to gauge consumer appetite for curved phones although its lack of other eye-catching features means it is unlikely to be a hit.

The Galaxy Round managed to create some buzz but it failed to catch the attention of a passerby as the curve is so subtle it is not apparent without a close look. The handset looks similar to Galaxy Note 3 as it has the same screen dimensions. But Galaxy Round's 5.7-inch (14.4-centimetre) display has a slight horizontal curve and weighs less than the Galaxy Note 3.

If one views it from either top or bottom, he/she can see that Round's left and right edges are raised slightly as Samsung shied away from putting a more dramatic curve in the display.

The reading experience on the smartphone comes as a disappointment, as when the phone is in an upright position the sentences of the text don’t look leveled and rather appear skewed. Though, it is only a problem when the phone is held vertically.

Samsung and many tech experts think that curved displays open up possibilities for bendable designs that could eventually transform the high-end smartphone market, where growth has slowed amid competition from low-end producers.

Samsung's Galaxy Gear smartwatch released last month has a flat screen, but the company is hoping to have the technology to make more attractive and wearable devices in what is shaping as a key battleground for consumer electronics companies.

Technology firms have yet to figure out how to cheaply mass produce the parts and come up with display panels that can be thin and heat-resistant. Batteries also have to take new forms to support flexible screens that can be rolled out, attached to uneven surfaces or even stretched. The battery in the Galaxy Round is, however, not curved.
