Not always created by companies, prototype devices are used further and fall into mass production. Many still remain unclaimed manufacturers. Two such devices from Nokia recently appeared on eBay.
The Kataya device has a design similar to the X series, made a few years ago, and runs on an unknown operating system that remotely resembles the first iOS. The cost of the device is $ 1,500.
The “Ion Mini” device has miniature sizes, runs on Snapdragon 400 in a 1 GB RAM and 8 GB ROM, and uses Android 4.3 Jelly Bean as the system. The cost of an exclusive device - $ 2,000.
