This story is being continuously updated…. New updates are being added at the bottom…..

Original story (from March 12) follows:

With the ongoing COVID-19 crisis, the world is on edge and China is taking majority of the hit. Chinese companies are also struggling to maintain their devices across the globe due to this issue.

We have seen a number of updates delayed because of this Corona Virus but some companies, despite everything, are really trying to keep things going. One such company is OnePlus.

OnePlus 7T

Soon after we saw the OnePlus 7T received the February patch this morning in China, the global variant is also getting some love in the form of an Oxygen OS Open Beta 1.

This new Oxygen OS Beta update is rolling out to both the OnePlus 7T and 7T Pro. The following is a changelog of the update, detailing a few of the changes that users who install it should expect.

-Optimized RAM management
-Enhanced single and double-tap performance of Ambient display and lock screen
-Improved content now live on the settings page
-Updated Android Security patch to 2020.02
Live Caption
-Added live caption feature, this will detect speech in media and automatically generates captions (to enable: Settings-System-AccessibIlity-Live Caption)
-Enhanced the contact details screen
-Fixed the audio and video issues with preloading videos

A few highlights from the changelog is the fact that OnePlus is bringing Live Caption to the OnePlus 7T and the 7T Pro. This feature debuted on Android 10 for Google’s Pixel devices. It uses Android 10’s built-in language processing to add subtitles to any supported video, even when the device is offline.

This update is still based on the February 2020 Android security patch level. Of course, we should see the March update rolling out at some point.
