The OnePlus 15 is now receiving a new global software update from OnePlus that delivers the Android security patch for February 2026, along with other enhancements aimed at improving system performance and touch responsiveness. This update is rolling out gradually in stages across global markets.

Update Details: Version, Size and Availability

Build Version: CPH2745_16.0.3.503

Size: Around 259 MB (may vary slightly by region)

OS Base: Continues to be Android 16 with OxygenOS 16

Rollout: The update is being distributed in stages, meaning it may appear on some devices earlier than others. Users should be patient as it spreads to all regions.

OnePlus typically releases updates incrementally to ensure stability and catch any unexpected issues before wider distribution.

What’s in the Update

1. February 2026 Android Security Patch

The headline inclusion in this update is the latest Android security patch for February 2026. Security patches are designed to fix vulnerabilities in the operating system, improve overall device security, and protect against potential exploits.

2. Touch Input Optimizations

The update includes enhancements to touch controls, which can lead to a more responsive and smoother touch experience during everyday use — especially in gaming, scrolling, or precise touchscreen interactions.

3. Improved System Stability

General system stability improvements help make the phone more reliable, reducing crashes or unexpected behavior under normal usage conditions.

What This Means for Users

Enhanced security: Installing the February 2026 patch ensures that known security vulnerabilities are addressed, keeping personal data and device integrity safer.

Smoother performance: With tweaks to touchscreen responsiveness and system stability, everyday interactions should feel slightly more refined.

Staged rollout: Because OnePlus distributes updates in phases, some users may receive the patch before others in their region. Checking for updates manually via Settings > About phone > software Updates can sometimes trigger the download sooner.

How This Fits Into OnePlus’s Update Strategy

OnePlus has been consistently updating the OnePlus 15 since its launch with regular patches and small feature improvements. Previous updates included feature additions, stability improvements, and older security patches in late 2025. With this February 2026 security update, the company continues its trend of ongoing support for its flagship model.

When You’ll See the Update

Because the update is staged, rollout timing may differ by market and carrier. Some regions may receive the update earlier, while others might see it arrive over the next few weeks. Users who don’t see the update yet are encouraged to check manually in the software update menu or wait a short while as the rollout completes.
