OxygenOS Open Beta 26/17 Update – 27 October 2017

The first Oreo-based builds for the devices highly aimed at bringing the new features. Since this was an initial release, we did expect some bugs. And after a few hours of usage users started reporting issues like Mobile Data drop, random reboots, and a few glitches with Oreo features like Notification Dots.

During the coming weeks, we believe that OnePlus has worked out these issues and finally released an update that concentrates only-and-only on fixing existing bugs. The update was announced at the OnePlus community forums by Adam Krisko as Open Beta 26 for the OnePlus 3 and Open Beta 17 for the 3T.

Before we jump to the instructions to install OxygenOS Open Beta 26/17, let us first take a look at the improvements and fixes that this release is bringing.

CHANGELOG

• User Feedback app is back
• Improved Wifi and Data connectivity
• NFC Performance has been improved
• Improved stability of Picture-in-Picture mode
• Reduced likelihood of device heating up in certain circumstances
• Fixed issue of missing voicemail tab in dialer
• Other general bug fixes
  • This includes things like the Notification dot issue, ambient display issues, random reboots, available storage calibration, and many other smaller issues.

There have been several confirmed reports of inclusion of an updated launcher app, now version 2.1.6 and improvements in fingerprint unlocking and Dash Charging. Unfortunately, it seems like the users are still troubled by camera focus and quality issues.

For the most part, it is great that the developers are focusing on providing a stable experience to the users, even though these are the Beta releases. The new improvements and almost issue-free builds are indicating that the stable release is somewhat near.
