Overview
- Strings in Samsung’s Auto Blocker app suggest One UI 9 may add a Memory Tagging Extension setting, though Samsung has not confirmed it.
- Memory Tagging Extension tags chunks of RAM so the system can spot bad reads or writes, which helps stop use‑after‑free bugs and data corruption.
- Code text warns the feature can slow a phone, leading reports to expect it will remain off by default if Samsung includes it.
- Google already exposes MTE on Pixel 8 and newer through Developer Options, and it turns on with Advanced Protection on those phones.
- One UI 9 is expected this summer, when users will see if the toggle ships and how much performance changes when MTE is enabled.
