Update 1 (4/19/2020 @ 12:10 AM ET): OnePlus has pulled the OTA following user complaints that they are unable to unlock their phones. We will update this article once the update rolls out again.

Earlier this week, OnePlus unveiled the OnePlus 8 series. Although the company's attention is mostly focused on promoting its two new smartphones, the company is still providing support for its previous generation flagships as promised. Now, the 2019 OnePlus 7 and OnePlus 7 Pro are receiving OTA updates to OxygenOS Open Beta 12.

OxygenOS Open Beta 12 brings the April 2020 Android Security Patch Level (SPL), a new feature in the OnePlus Camera app to detect dirt on the camera lens, ringing duration information for missed phone calls, and more. This update follows Open Beta 11 last month which brought the Android Security Patch Level to March 2020 and also added the Instant Translation feature. The stable update for the 7 series also rolled out last month with the March 2020 SPL.
