What is Project Treble for Android?

Google has launched a new way of updating Android OS(Operating System) starting in 2018 called, “Project Treble”.   Although Google uses pure “100%” Android OS on their Nexus/Pixel devices such as the Pixel and Pixel 2 smartphones, many manufacturers like Samsung, LG, Huawei, Xiaomi, and others have added their own UI/skin on top.  In extreme cases like Samsung, they have added S-Pen features to their Samsung Galaxy Note series and lots of new hardware features not found in the original Android OS.  Due to this reason, whenever Google updates their OS from one iteration to another(such as Android 7.0 Nougat to 8.0 Oreo), manufacturers have to re-build the whole OS from ground up, causing months of delay in updates.  For example, Android Oreo update for Galaxy S7 probably took around 8 months.  This has been a troubling problem as Android OS updates once a year and by the time manufacturers update their software to the latest, they are already at least 6 months behind.

Project Treble mean Faster OTA Updates!

Basically, with Project Treble, there is another layer of operating system which separates the manufacturers’ add-ons from the actual Android OS.  Which means, everytime Android OS is updated, companies like Samsung or LG no longer have to re-build the Android OS from ground-up to make it work with their extra features.  Of course, this also means that one day, users may be able to update Android OS completely separate from manufacturers’ updates, they may even become separate updates.  Now, this is how Android should have been built but Google probably never expected that Android OS would be used by more than 50% of smartphone companies in the world.

Now, Project Treble is only going to be supported on newer Android devices like Galaxy S9, OnePlus 6, and most new devices from June 2018 should be Project Treble compatible.   Of course, there are exceptions to this such as the OnePlus 5 or 5T, which will also support Project Treble.

What does Project Treble mean for Root and Custom ROMs?

Now, for the Android root and custom ROM world, this also means that you will be able to install GSI(Generic System Image), similar to a custom ROM, but it is not device-dependent and the user will be able to install GSI onto any Android device that supports Project Treble.  For example, if a developer made a custom ROM called Resurrection Remix ROM and provided a GSI, then users with ANY Android device that has Project Treble can install that ROM and would run near flawless without additional changes.  In fact, there is a Resurrection Remix ROM that you can install on any Android device with Project Treble!

Current List of Phones that Support Project Treble:
