TL;DR
- One UI 9 is expected to introduce a Memory Tagging Extension (MTE) toggle directly in the Auto Blocker app.
- MTE leverages Arm v9 CPU features to actively tag memory blocks, shutting down unauthorized access, data corruption, and security holes as they happen.
- This elevated security isn’t free — Samsung warns that enabling MTE will slightly reduce your phone’s performance.
Most people don’t realize how easily apps can misuse your phone’s memory. Simple memory mistakes can lead to corrupted data, unauthorized access, or even security holes. Arm’s v9 CPUs have a hardware feature called Memory Tagging Extension (MTE) that can catch these bugs as they happen. Until recently, though, hardly any phones let you enable it.
This might be about to change. Some strings we’ve spotted in Samsung’s Auto Blocker app suggests that One UI 9 could let users turn on MTE with a simple switch.
