Phh-Treble: The Ultimate Project Treble AOSP ROM
Before we head over to guide you to install Project Treble AOSP ROM, let us see how Treble has a huge effect on custom ROMs.
Treble is basically Google’s innovation that will now modularize the lower layer of Android by drawing a line between the Android framework and the OEM’s proprietary code (Blobs). Which means that the software updates will no more be slowed down due to lack of drivers from OEMs and chip manufacturers (Like Qualcomm). Thus, any device that supports Treble will easily be able to boot a generic AOSP ROM, irrespective of the device’s OEM or the SoC they operate on. Today, you will be able to witness the feature in action and install Project Treble AOSP ROM on your device.
“Long story short, you will need to wait for less time and have faster support for latest Android versions using custom ROMs.”
