We’re also getting word that the company willnotsupportProject Trebleon either the 3/3T or 5/5T. Project Treble was introduced earlier this year and aims tobring faster updates to Android devices. It works by separating the OS code from the vendor code. This would allow vendors like Samsung or LG to push core OS updates to its phones without re-optimizing its own code.
Krisko didn’t elaborate on why Treble won’t be supported, but simply stated that OnePlus is not currently supporting Treble and does not plan to for these devices.
What do you think about OnePlus promising to update the OnePlus 3 and 3T to Android 8.1? Is the lack of Treble support a deal-breaker for you? Let us know down in the comments.
