After rolling out the first Android Pie-based Community Beta for the OnePlus 3 and 3T smartphones last month, OnePlus has now rolled out the second community beta for the two 2016 flagships. However, the second beta build does not come with any major new features.
The second Android Pie-based Community Beta build for the OnePlus 3 and OnePlus 3T primarily focuses on bug fixes. It fixes crash issues with the native messaging app present in the first build. Once you install the new beta build, you will also notice that the Clock timer and stopwatch interface display is no longer incomplete. Users who had installed the first build had reported that microphones stopped working when earphones are plugged in. This issue has also been solved in the second beta build.
In case you had installed the first Community Beta on your OnePlus 3 or OnePlus 3T, you will need to download the latest build and install it using the fastboot method. You can find the latest Android Pie Community Beta build for the OnePlus 3 here. If you own a OnePlus 3T, download the latest build from this link. However, it is important to keep in mind that you will need to perform a backup of your data before you proceed to install the second beta on your device.
If you are running a stable OxygenOS build on your OnePlus 3 or 3T, you will need to install it using either the Local Update method or as a Recovery Update. To install using the Local Update, you will need to download the file from the link above and move it to the root folder of the internal storage. Once you are done moving the file, open the Settings Menu and head over to System update > Local update. Tap on the downloaded file and wait for the device to reboot.
The Recovery Update method involves turning off the smartphone and entering the Fastboot Mode. To enter Fastboot Mode, you will need to press power and volume up key simultaneously. Next, navigate to Recovery option using volume and select the downloaded zip file to finish the installation.
