After the H83XX series, two news Sony smartphone series have been revealed through their user-agent profiles – H81XX and H82XX. The first one is clearly a premium/high-end device with at least two versions (H8116 and H8166), featuring 2160 x 3840 pixel display and Android Oreo OS.
This would make the Sony H81XX the successor of the XZ Premium and the third phone by the Japanese company with a 4K screen. It will likely be the first to bring the high resolution to a phone with minimal bezels, as Sony already confirmed it will be going in that direction in 2018.
Another phone to pop up…
