The OnePlus 5T ships with Android 7.1.1 "Nougat" and uses the OxygenOS user interface, OnePlus' proprietary custom skin built on top of Android, adding various features not found in the stock Android operating system, such as night mode and reading mode, which both change the color temperature of the device's screen, and the ability to change the Bluetooth audio codec. The night mode reduces the screen's color temperature to reduce blue light levels, while the reading mode applies a monochrome-like effect to the screen. Unlike the OnePlus 5, the 5T no longer overrides the performance scaling in benchmarks to max out CPU and GPU clocks in specific applications, this makes benchmarks being run on the 5T more accurate.
