When you open Oxygen Updater for the first time, you will be asked to select your device and your update method. These are usually set to the right values, but you are free to change them according to your likings.
There are a couple of different update methods:

- Incremental updates: Incremental updates are update packages meant to update a specific version of OxygenOS to a newer version. These updates are small to download but do not work on rooted or bootloader-unlocked devices. For most people, this is the recommended way to update. If an incremental package is not available for your specific OxygenOS version, the app automatically offers a full package instead.
- Full updates: Updates which also work on rooted and bootloader-unlocked devices. However, these updates are very large to download. Only recommended if you have root access or have a bootloader-unlocked device.
- Open Betas: Do you want to experience even newer software than most other people around you? Then you can also switch to (and update) the OxygenOS Open Betas using this app. The Open Betas come both in full and incremental packages. These work the same as explained for the regular versions above.
