OnePlus has left the U.S. market, but you might be wondering if the company will continue after-sales support in the future. Especially since some third-party retailers still have the OnePlus 15R and OnePlus 15 in stock. But if you are to get your hands on one now, how many updates will the phone get, and if you own an older model, will it make it to Android 18? The latest OnePlus phones are currently on OxygenOS 16, which is based on Android 16. OnePlus released OxygenOS 16 in North America in December 2025, about seven months after Google released the final stable version of Android 16.
Android 18 is expected to release in mid-2027; OPPO and OnePlus will likely have the next major Android update rolled out a few months after, based on the update history. OnePlus phones with multiple years of support since 2024 should be eligible for Android 18. Regarding whether it's worth keeping or buying a OnePlus phone in 2026, OnePlus said current users in Europe and North America will receive after-sales support, and all software updates and warranties will be honored, meaning the process stays the same as any other manufacturer still servicing phones in the region.
