OnePlus has pushed out the first software update for the OnePlus 15 less 24 hours after the phone’s launch. The company is rolling out OxygenOS 16.0.1.303 in both India and the EU.

The update is available as version CPH2745_16.0.1.303(EX01) in India and CPH2747_16.0.1.303(EX01) in the EU. OnePlus says the rollout is incremental, with a wider release planned over the next few days.

The update includes the November 2025 Android security patch and several functional changes. OnePlus has focused on faster app launch speeds from the home screen, new customization options, and upgrades to the system’s security and network features.

Users can now resize the clock when editing select Flux themes, rename widgets, and stack widgets by dragging them onto others of the same size. Photos gets a small but useful improvement with automatic straightening for portrait and architectural shots when cropping or rotating.

The update also adds the option to set videos as ringtones. Phone Manager now scans for threats faster, and the Lock screen’s “Ring” fingerprint animation gains a glowing effect.

On the network side, OnePlus has added a new interface for the AI LinkBoost Network Engine. Users can check how many network optimizations have been applied and view details on reduced lag.

Real-time alerts for network acceleration will now appear when the phone detects poor connectivity. The update also includes tools to test network speed, latency, and upload and download rates.

OnePlus notes that the OTA may arrive at different times depending on the region. The company also reminds Indian users that they can report device issues directly from the OnePlus Community App under the Bug Report section, or by dialing *#800# to access the feedback tool.
