Back in the last week, OnePlus rolled out the first OxygenOS Open Beta for the OnePlus 7T and 7T Pro smartphones. The update introduced February 2020 security patch and Live Caption feature. Now, the Chinese tech giant is rolling out the second beta update that bumps up the Android security patch level on the 7T and 7T Pro to March 2020. The second Open Beta update also introduces the Instant Translation feature. The name is self-explaining; it provides real-time subtitles during video calls. It currently supports English, French, German, Hindi, and Chinese languages. You can check the changelog of the Open Beta 2 update below.
