Download OnePlus 3 OxygenOS Open Beta 25 Android 8.0 Oreo

Download OnePlus 3 OxygenOS Open Beta 25 Android 8.0 Oreo: OnePlus just released the Android 8.0 Oreo Oxygen OS Open Beta 25 build for the OnePlus 3. With this release, OnePlus became the very first Android smartphone manufacturer to open any kind of Oreo firmware for a phone. OnePlus 3 users can flash the Open Beta on their phone and enjoy the Oreo goodies right away.

OnePlus has been going through dark clouds for quite a while. The company came across a number of problems in the recent few months. At first, the company was expected to update the OnePlus 2 to Android Nougat, but that update never happened. This disappointed every single OnePlus 2 user. Users almost lost their faith in the company. Everyone doubted the Oreo update for the OnePlus 3, and it finally started happening. In parallel, OnePlus is also going through the user data collection controversy. OnePlus even admitted that its collecting user data and it will stop by this year’s end. It looks like OnePlus announced the Android Oreo Open Beta to overcome this recent spark of negativity. OnePlus is trying its best to bring back its lost reputation. This may not be as easy for the Chinese manufacturer.

The OnePlus 3 ran on Android 6.0.1 Marshmallow out of the box. The company updated this phone to Android 7.1.1 Nougat as well. To ensure faster software updates, OnePlus merged the HydrogenOS and OxygenOS development teams as well. The Android Oreo Open Beta update maybe a result of this hybrid of OxygenOS and HydrogenOS development team as well. If you own a OnePlus 3 then it’s time for you to grab the OnePlus 3 OxygenOS Open Beta 25 Android 8.0 Oreo update and install on your phone without wasting a minute.

The OxygenOS Open Beta 25 Android Oreo can be installed on OnePlus 3 either through the recovery of the phone or by using the ADB Sideload method. You can have a look at both the methods and go with the one that seems the best to you.
