In early July of this year, I added Project Treble support for the old device such as 5/5T in the beta version of Oxygen OS, which means that these two models will be faster in subsequent Android version upgrades. Committed in the overseas official forum, promised to bring a number of new features to the oxygen OS system of the 5, 5T mobile phone, including the 'front portrait' mode.
