OnePlus 15 and 13s Receive March Security Patch and New Tools

OnePlus has begun rolling out the OxygenOS 16.0.5.700 update for the OnePlus 15 and OnePlus 13s in India. The update is being released in batches as an incremental over-the-air rollout, with a small number of users receiving it first and broader availability expected in the coming days.

For the OnePlus 15, the update arrives with firmware version CPH2745_16.0.5.700(EX01). The OnePlus 13s receives version CPH2723_16.0.5.700(EX01).

The update introduces several improvements aimed at productivity and usability. Both devices now support multiple simultaneous timers, allowing users to run several timers at once.

The timer interface has also been updated to display estimated stop times, helping users track when each timer will finish.

The Content Portal has also been updated with support for app clones, allowing easier sharing of content between apps or accounts.

Connectivity options have also been updated with a new Automatically open received files setting. This option allows users to decide whether files received through sharing services should open automatically after download.

The OnePlus 13s receives an additional accessibility feature called Motion cues, designed to help reduce motion sickness when using the phone in moving vehicles. It can be enabled through Settings → Accessibility & convenience → Motion cues.

Both smartphones also receive the March 2026 Android security patch, which improves system security and stability.

Because the update is rolling out gradually, some users may receive it later than others.

Users who have not yet received the notification can manually check by opening Settings → About device → OxygenOS version → Check for updates. If available, they can select Download and install and restart the device after installation to complete the update.
