OnePlus is busy rolling out several updates for its beloved smartphones. Right now, the OnePlus 3 and 3T phones are receiving yet another Android 8.0 Oreo based Open Beta 26/17 OTA update. Yesterday, we saw OnePlus 2 getting the Oxygen OS 3.6.1 OTA with latest October 2017 security patch. Though it is still based on 6.0 Marshmallow, it does feature KRACK WPA2 vulnerability patch. Before that, OnePlus 5 received Oxygen OS 4.5.13. Now, download and install the OnePlus 3/3T Open Beta 26/17 firmware build based on Android 8.0 Oreo.

The latest Open Beta 26 for OnePlus 3 features a solid number of bug fixes like improvements to WiFi and Data connectivity, improved performance for NFC, Picture-in-Picture now works properly, and much more. After the update, you will also see that the unusual heating of the device during certain operations is now gone. It is still based on September 2017 patch.

Although there are several bug fixes, stability improvements, and performance enhancements, it still possess a few bugs. This includes slower fingerprint actions for one. Third-party apps may not be completely optimized or compatible. After all it’s a beta update and some minor bugs are acceptable at this point.

The same goes for the Open Beta 17 for OnePlus 3T. Being sister phones, the updates are same for both the devices. They even have the common stable Oxygen OS 4.5.1 OTA update. The phones are sure to receive the stable Android 8.0 Oreo with Oxygen OS 5.0 or later before the end of this year. Though Oreo will be the last firmware upgrade for the OnePlus 3/3T, they will continue to receive monthly security patch upgrades.
