The YotaPhone 2 made its official debut at the end of 2014, before going on sale in early 2015. The handset had a Snapdragon 801 processor, 2GB RAM, 32GB of storage, and plenty of other high-end specs - but like its predecessor, the most distinctive feature of the YotaPhone 2 was the fact that it had two displays: a 5-inch full-color Full HD AMOLED on the front, and a slightly smaller, lower-resolution, monochromatic e-ink display on the rear.
The device launched with Android 4.4.3 KitKat onboard, but was upgraded to Android 5.0 Lollipop in May 2015. Now, almost two years later, Yota is upgrading the device with a newer version of the OS.
However, if you were hoping to see the YotaPhone 2 get bumped up to Android 7.0 Nougat, you'll be disappointed. Instead, the Russian company is updating it to Android 6.0 Marshmallow, which Google originally released in October 2015. Google has already revealed its next major OS version beyond Nougat, currently referred to as 'Android O'.
Meanwhile, Yota has now started teasing its successor to the dual-display device. Last month, the company confirmed that a third-generation YotaPhone was in development, and now, it's updated its Russian website with a teaser image, which states that it will open pre-orders this summer.
The image reveals nothing significant about the new handset, but it seems likely to continue the two-screen tradition of its predecessors.
