Display Features: Support for the 120Hz refresh rate and 21:9 aspect ratio is standard in most stable builds, though Sony-specific audio tuning algorithms (like DSEE Ultimate) may be lost.
Hardware Sensors: Standard features like the side-mounted fingerprint reader, 3.5mm jack, NFC, and Stereo speakers are generally supported. Development Basics
