Let’s start with the upgrades to the operating system.

OxygenOS 15 uses what OnePlus calls Parallel Processing, which allows multiple operations to run simultaneously.

Moving on to the look of OxygenOS 15, you’ll find some differences there, too.

Then there’s the AI.

Most of these improvements are in the camera, but they’re useful.

Two additional features worth noting are theft protection and Sharing with iPhone.

Theft Protection uses the machine’s accelerometer to determine if your phone was last lost or stolen.

Share with iPhone has already proved useful to me.

I can send files from My OnePlus 12 to my iPhone with a couple of simple taps.
