The OnePlus 6 has been updated to OxygenOS 9.0.3, a relatively large update that makes significant improvements. In addition, the smartphone now has the latest security update, so that it is protected against vulnerabilities in Android.
OxygenOS 9.0.3 now available for OnePlus 6
OnePlus has released OxygenOS 9.0.3 for the OnePlus 6, the device that appeared in May 2018. The update brings with it the necessary improvements. This improves the stability of the Wi-Fi and bluetooth and changes have been made in the Nightscape and slow motion modes of the camera. This means better photos in the dark and slow motion videos have to be made.
More important is that there is now an audio tuner for paired bluetooth headsets. This allows users to put together a sound profile that best suits them. Finally, OxygenOS 9.0.3 contains the security update of December 2018. OnePlus promises to provide all its smartphones with a security patch at least once every two months.
An update is also available for the slightly older OnePlus 5 and 5T. Version 9.0.1 of OxygenOS introduces several improvements for the Wi-Fi connection, sRGB and Reading mode. Some smaller bugs are also solved. The update will be rolled out to all users within a few days.
Android Pie already available
The OnePlus 6, 5T and 5 were previously updated to Android Pie. The update for the 5 (T) appeared just before the end of the year, while the OnePlus 6 has been running on the latest version of the mobile operating system for some time. This means that the smartphone belongs to the small group of Android smartphones with Pie. The Chinese manufacturer has also promised to update the older OnePlus 3 and 3T, although this update will take some time to wait.
Yet it is special that the smartphones still get an Android Pie update, since they have been previously updated to Android Nougat and Oreo. But few manufacturers give their smartphones three major software upgrades. The OnePlus 6T was also one of the first smartphones to run out of the box on the new version.

Note: If there is more than one download option, that likely means that you need to download and install the Bug Fix Update for your smartphone or tablet device before you can actually update to Android 12.
Step 1:
Before you go trying to update your device, you should check which version of Android you are running. You might already be on the latest version. It's easy to check so follow this guide up to step four. This screen will have a section called 'Android version'. If it doesn't, click 'Software information' to find out.
Step 2:
Scroll down the Settings menu and click on 'About Phone' or 'About Tablet'. If you have a tabbed settings menu then this will appear in the 'general' section.

Refer to Android developer page to choose which version of Android your phone or tablet is running. I.e, 4.0.4 corresponds to Ice Cream Sandwich, an old version of Android that was released in 2013.
Step 3:
Note: Your phone or tablet may require a Wi-Fi connection to search for an update. We suggest you to download the software Droid Over Wi-Fi because the file size can be large.
Choose and click the "Software Update" option. Next it will search available update for your phone or tablet. If update is available, you will be asked if you want to install it. Select "yes" and it will install the new operating system in your device. If you want to install it later, you can download the Android 12 file first. Download Android 12.zip
