Tuesday night, Samsung introduced the first smartphone to come with a curved display. The Samsung Galaxy Round isn't traveling too far away as it will make its debut and launch in Korea on Thursday. Priced at 1.09 million won ($1013 USD), the device will originally be offered in Luxury Brown but other colors will be available later. The Samsung Galaxy Round offers what is called the "roll effect" where the phone is tipped downward in the landscape mode and shows the time, missed calls and battery level (see video below).
Other features include something called the Gravity Effect which offers "visual interaction" with the screen. The display is off while the music player is running, so you can press the left side of the screen to play the previous track, and tap the right side of the screen to play the next track. Side Mirror allows you to tilt the phone to the left or right to access certain photos and video in your gallery. Multi Window is included on the handset allowing you to multitask by opening two apps at the same time, both apps claiming part of the screen. This is the world's first curved screen phone. But the question is- Do we really need a curved screen??.. We will get the answer in perhaps coming 5 to 6 months when LG will also unveil some ground breaking stuff with foldable batteries and phones.
The 5.7 inch Super AMOLED screen offers resolution of 1080 x 1920, and is powered by a quad-core 2.3GHz processor with 3GB of RAM on board. A 2800mAh battery powers the unit which has Android 4.3 pre-installed. The handset is equipped with a 13MP rear-facing camera. While the phone has just been introduced, we could soon see major competition. Fellow Korean manufacturer LG said on Monday that its display unit is ready to release a flexible OLED panel.
