OnePlus 3 and 3T enthusiasts have been able to benefit from the company's OxygenOS Open Beta program for quite some time now, and its latest release, Open Beta 6 (Open Beta 15 for the older OnePlus 3), once again brings in a number of improvements to the company's own take on Android.
Open Beta 5, focused mostly on squashing bugs from earlier releases, the newest OxygenOS version introduces a number of new features as well, mostly focusing on the user interface of built-in apps. Some of the biggest changes come to the Dialer app in the form of a couple of new gestures: when receiving a call, users will be able to swipe down to answer it, or swipe up to reject it.While the previous build,
The UI in several apps has also been tweaked: the in-call interface has been changed to reflect the new answering gestures, while Messages and Settings have received a new, collapsible action bar which OnePlus says will be making its way to other apps in the future.
Another important change is buried under the tag "Bluetooth optimizations". This is, in fact, the addition of support for the aptX codec, which was recently released for OnePlus' China-only HydrogenOS as well. In practice, this means that users with compatible headphones will be able to benefit from better overall audio quality. The feature is enabled by default, but can be turned off from the Developer Settings menu, should one choose to do so.
Other improvements listed are optimizations for Night Mode and high power usage notifications, as well as bug fixes. Users of OnePlus' forums report the update fixes a major bug with duplicate contacts in the Dialer app caused by third-party apps such as WhatsApp.
As usual, users of previous Open Beta releases should start receiving the update via OTA soon, while those running the stable version of OxygenOS will have to migrate manually. However, keep in mind that doing so disables the ability to migrate back to the stable channel without performing a full wipe of the device.
