The YotaPhone 2 has finally gone on sale in the United States, with the Russian manufacturer Yota Devices revealing the pricing and preorder details for the second version of its dual-screen smartphone, six months after it was launched in Europe.

The YotaPhone 2 sports not one, but two displays with a normal AMOLED 5-inch front screen having a resolution of 1080 x 1920 pixels, and an always-on, 4.7-inch E-ink rear screen with a resolution of 540 x 960 pixels. The YotaPhone uses a combination of its YETI (Yota E-Ink Technology Integration) software that runs on top of Android with the rear e-ink display. The traditional front display can be used for gaming, messaging, web browsing, and watching videos, while the e-paper display on the back allows users to read books, check basic social networks and news apps, without excessive battery drain.

The dual-screen smartphone is powered by the Qualcomm Snapdragon 800 system chip, paired with 2GB of RAM, and offers 32GB of internal storage. The YotaPhone 2 has an 8-megapixel rear camera and is powered by a 2500 mAh battery.

The YotaPhone 2 has now arrived in the U.S. through IndieGogo, a crowdfunding website, which is offering the dual-display smartphone at a special price of $500 for the first 100 backers (already exhausted), as against the full manufacturer's suggested retail price of $600. Buyers can still preorder the YotaPhone 2 at a price of $525 for 48 hours and for $550 until the campaign ends in July.

Yota Devices is aiming to hit a goal of $50,000 to help pay for the "certifications and regulatory fees" needed to launch the phone in the U.S. The IndieGogo campaign managed to raise over $70,000 within a few hours and the company has already surpassed its goal with 61 days still left for attracting more early adopters.
