Not much is known about the Hydrogen OS 3.0 for OnePlus 3 or 3T at the moment, but it sure is a great deal as it will most likely possess better features than the usual Oxygen OS 4.0.3 official firmware. We will make sure if the H2OS is based on the Android 7.0 Nougat update or not. It will be clear until we get the changelog. The H2OS beta versions are sure based on the Android 7.0 Nougat firmware.
As the Hydrogen OS is a firmware for the Chinese variant, it doesn’t come with the Google Apps pre-installed. You will need to install it separately. Fortunately, we already have a Google play store installed APK which can easily install the Google Play Services onto your Android device.
