As promised, Android Pie is making its way to the OnePlus 5 and 5T. Like most Chinese OEMs, OnePlus maintains two versions of its Android fork. The Chinese variant—known as HydrogenOS— lacks some of OxygenOS' features such as Google Play services and support for additional languages. Users outside of China can sideload the China-only ROM, and today OnePlus is now allowing the public to beta test the Android Pie version of HydrogenOS for the OnePlus 5 and the OnePlus 5T. Here is the changelog:

System

Update to Android P versionBrand new UI design, more details, etc.A new background control solution for a lighter and smoother experienceAndroid patch update to 2018.11

Communication

SMS verification code spreads the display, check the verification code one step fasterOptimize strange number recognitionAdded the ability to set a default card for a single contact or group in dual card modeOptimize the speed dial and call interface UI designEmergency rescue UI optimization

Do Not Disturb Mode

OnePlus Weather

Positioning is accurate to the areaImprove the accuracy of weather dataDesktop widgets automatically switch cities based on targetingSolve the problem of refresh failure after positioning changeSupport fuzzy search when adding cities to solve the problem that some users cannot search for cities

An OxygenOS public beta shouldn't be too far off as the two builds are identical except for the differences mentioned above. If you own a OnePlus 5 and 5T and want to try out Pie, head over to the official HydrogenOS website (in Chinese) for download links and instructions. For Google Play services to work, you will need to sideload GApps separately from here. We recommend opting for the 'nano' package as higher-tier ones are known to cause issues in Chinese ROMs.
