OnePlus has started rolling out its stable OxygenOS 16 update based on Android 16 to the OnePlus 12, with India getting the first wave of builds. If you own the handset and bought it locally, the upgrade should reach you soon — it’s already on the move.
What’s included and where it’s available first
The initial firmware hitting Indian units is labeled CPH2573_16.0.0.201(EX01). OnePlus describes a long list of changes in the official changelog, covering UI tweaks, performance improvements and under-the-hood optimizations that accompany Android 16. The company says the rollout is phased, so expect the update to expand to more regions in the coming days.
Why the staggered rollout matters
Updates are typically distributed in batches to limit issues and catch any unforeseen problems before a global push. That means even if your OnePlus 12 was purchased in India, you might not see the notification immediately — patience is key. If an issue is detected, OnePlus can pause distribution, patch the build and resume, protecting the wider user base.

How to check and prepare for the update
- Go to Settings > System > System updates to check manually.
- Back up important data before installing major OS updates.
- Install over stable Wi‑Fi and keep battery above 50% (or plug in).
- Allow the device a little time after the update for system optimizations to complete.
OnePlus has published the full changelog on its support channels; if you like to dig into details, check that source for a line-by-line breakdown. For everyone else, the key takeaway is simple: OxygenOS 16 on the OnePlus 12 brings Android 16 to the device, and the phased rollout means it should arrive on more phones soon.
