OnePlus now blocks older Android versions on new phones to close security holes. The maker will use a physical check inside the device to stop hackers from reverting to old code.
Software patches often have gaps that bad actors can slip through. Engineers at OnePlus found that users could still install older firmware to bypass these gaps. A hardware fix changes that reality.
The change will likely come with next year's device launches. Regional updates might follow later in the year.
The new check blocks downgrades
OnePlus adds a special code that runs at the very first boot. This code looks for signs of tampering. If it finds them, the phone will not load the operating system.
Developers are watching how this system handles older versions. Security researchers think it will make the phone ecosystem much safer. Some users may feel annoyed by the loss of freedom to choose their software.
Why the community worries
Enthusiasts who build custom ROMs face a hard limit. They rely on older firmware to keep specific features working. That window is now closing fast.
The maker has not responded to a request for comment. Many users asked for more details on the plan.
OnePlus says the trade-off is worth the risk. A locked device is easier to keep safe from viruses.
What happens next
The rollout depends on upcoming hardware releases. Watch for official firmware notes from the manufacturer. Developers will likely adjust their tools to match the new rules.
