Sailfish OS for Sony Xperia X officially launched, but you'll have to pay for it
Apparently, Sony Mobile allowed Jolla, the company behind Sailfish OS to optimize the platform for its Xperia X smartphones. Today, Jolla announced that its new Sailfish X operating system for Sony Xperia X has gone gold and will soon be available for purchase.
However, sales for the product will open on September 27 in Europe, but Jolla might offer the new Sailfish X in North America (Canada and United States) as well.
Unfortunately, not all features will be officially supported in the first software release, which means you can expect some issues with Bluetooth, new sensors (barometer, step counter, etc.), fingerprint sensor, and FM Radio.
