OnePlus has confirmed that the OnePlus 13 and OnePlus 13R will receive four major OS updates, specifically Android 16, 17, 18, and 19, as originally promised. This clarification came after a miscommunication from a OnePlus PR representative suggested that the initial software version would count toward the updates. Additionally, the 13-series will receive security updates for six years, an extension from the previously promised five years. OnePlus maintains that four OS updates represent the optimal policy for their devices.
Alright, you can set aside those pitchforks – the OnePlus 13 and OnePlus 13R will indeed receive the promised 4 major OS updates. To clarify, this includes Android versions 16, 17, 18, and 19 (the two devices launched with Android 15).
Earlier today, some confusion arose when a OnePlus US PR representative stated that the out-of-the-box software would count as one of the four updates. That statement was illogical, and the company has since confirmed that it will not be doing so.
