The system images of the OxygenOS 5.0.1 for the OnePlus 3 and the OnePlus 3T can now be downloaded by interested users from the website of the smartphone manufacturer OnePlus. This comes a few days after the tech firm started distributing the software upgrade over-the-air. The availability of the system image allows users to flash the software build to their devices. Installing this update brings several new features to the two devices, including the new "Soft" screen calibration option. The "Soft" screen calibration option has been described to have a cooler white balance compared to the sRGB option while also having reduced color saturation compared to the default calibration option.
The OxygenOS 5.0.1 brings the support for the aptxHD codec to the OnePlus 3 and the OnePlus 3T, which allows for improved audio quality on Bluetooth speakers and headphones. This audio codec supports 24-bit music quality over Bluetooth, an improvement over the 16-bit quality supported by the older aptX codec. The technology offers a lower signal to noise ratio by adding two extra bits to every sub-band of processing. The aptxHD codec enables the transmission of audio data with a sampling rate of 48kHz. This software upgrade brings the Wi-Fi hotspot device manager to the two smartphones, and it will also allow the OnePlus 3 to support the LTE network of the Indian network operator AirTel. In addition, this update brings the December 2017 Android Security Patch to the two handsets. This security patch contains fixes for several vulnerabilities, some of which are located in the system component and the media framework of Google's operating system. The software package also includes a number of bug fixes and stability improvements, although the manufacturer did not provide any information regarding the bug fixes in the changelog.
On the manufacturer’s official website, OnePlus provided detailed instructions on how to flash the system image to the two smartphones. The company is advising users to backup the files and images stored in the handset to a personal computer or a microSD card before flashing the system image. Moreover, it is also important to verify first if the internal storage of the smartphone has enough free space to temporarily keep the system image, which has a file size of 1.47GB.
