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.
Code Copy Text <string name="mte_preference_title">Enables memory tagging extension</string> <string name="mte_preference_description_phone">Detects and prevents memory issues like corruption and unauthorized access in your apps by tagging memory blocks. Ensures memory is used correctly, enhancing security and stability. This can reduce your phone's performance.</string>
This feature isn’t just an idea — Pixel 8 phones already have it in Developer Options, and it turns on automatically with Advanced Protection. Now it looks like Samsung is getting ready to do the same.
So what does MTE actually do? It tags memory blocks so the system can spot when an app tries to use them the wrong way, like reading from a place it shouldn’t or writing into another app’s space. This means fewer crashes, better stability, and stronger protection against common security exploits.
