Partitions were not required for Android N and previous versions of Android, all of our current devices do not feature a partition.
In addition to bringing support for Project Treble, the latest OnePlus beta also includes a ton of new features.
On the other hand, the new beta build will bring changes to the OxygenOS interface by adding support for accent colours, alongside improvements to the launcher, phone and weather app.
The pre-stable firmware will seed support for Project Treble which means devices that launch with Android Oreo will be compatible with modular OTA updates directly from Google. It even confirmed that the OnePlus 5 and 5T would not receive this feature. The former is getting OxygenOS Open Beta 13, while the latter is being upgraded to OxygenOS Open Beta 11.
Project Treble, which is explained below, is mandatory for every Certified Android device launching with Android 8.0 Oreo and above.
After several months of evaluation and hard work, we finally found a solution to make this possible, and we are very excited to share this good news with you.
Last month, Chinese smartphone brand OnePlus released OxygenOS Open Beta update 12 and 10 for OnePlus 5 and 5T that came with June security patch and some optimizations to reduce the oil painting effect. In August a year ago, Google engineers on an Android Developers Backstage podcast episode confirmed that they are working with OEMs to bring Project Treble to a mass level.
Accent color customization support has been ready for the OnePlus 5 and 5T and will soon roll out for the new OnePlus 6 and the older OnePlus 3/3T and the OnePlus 5/5T. What is that new user interface they are talking about? The hidden app list and toolbox has also been improved. OnePlus also optimised logic for the contact page in the OnePlus Dialer app, and the OnePlus Weather app has been completely redesigned. Otherwise, you should clear all data and cache from recovery before flashing the latest build. Note that flashing will wipe the contents of the phone, and users will need to back up their data first.
