Sony said it would begin selling its new high-end smartphone, the Xperia XZ Premium, in the United States for $800. Preorders start on June 12 for delivery June 19.

The unlocked phone will be sold online and is compatible with GSM networks, like those of AT&T t and T-Mobile tmus . The price is higher than the $725 for Samsung’s Galaxy S8, which has the same amount of storage and a slightly larger screen.

But the Sony’s 5.5-inch screen is the first with an ultra high resolution 4K display with high dynamic range. There’s not much content available yet in 4K, though Netflix, Amazon, and other streaming video players are adding more all the time. New Netflix nflx shows like Stranger Things are available in 4K, for example.

Sony has largely been an also-ran in smartphones, but is aiming for a comeback via the “unlocked” market, selling phones online through Amazon amzn and in stores like Best Buy bby without partnering with mobile carriers. The unlocked market overall grew 12% last year, according to the NPD Group.
