Update (10/30/19 @ 1:15 PM ET): OxygenOS Open Beta 4 is now rolling out for the OnePlus 7.

Earlier this month, OnePlus rolled out OxygenOS Open Beta 3 for the OnePlus 7 and OnePlus 7 Pro. As part of the update, OnePlus released a bunch of bug fixes and a couple of new features. Most notably, the company rolled out a new Work-Life Balance feature for users in India. This new feature allows users to sort notifications when at work or home, giving them some peace of mind. The update also included optimizations for the OnePlus Switch app and a new Activity mode in OnePlus' Zen Mode. Now, the company is rolling out OxygenOS Open Beta 4 for the two devices with even more new features.

As per a recent post on the OnePlus forums, OxygenOS Open Beta 4 is now rolling out to the OnePlus 7 Pro and is expected to reach OnePlus 7 users next week. The update includes the usual bug fixes and improvements, along with some optimizations for some stock apps. Most notably, the update introduces a new "Raise to lower the ringtone" gesture within the Sounds & Vibration settings. When enabled, this feature will automatically lower the volume of your ringtone when you pick up your phone to answer an incoming call. Furthermore, the update adds The Weather Channel as a data source in OnePlus' stock Weather app.

Here's the complete changelog for the OxygenOS Open Beta 4:
