TL;DR<\/p>\n
Most people don\u2019t realize how easily apps can misuse your phone\u2019s memory. Simple memory mistakes can lead to corrupted data, unauthorized access, or even security holes. Arm\u2019s 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<\/a> let you enable it.<\/p>\n This might be about to change. Some strings we\u2019ve spotted in Samsung\u2019s Auto Blocker app suggests that One UI 9<\/a> could let users turn on MTE with a simple switch.<\/p>\n Code<\/p>\n Copy TextEnables memory tagging extension<\/strong>
This feature isn\u2019t just an idea \u2014 Pixel 8 phones already have it in Developer Options, and it turns on automatically with Advanced Protection<\/a>. Now it looks like Samsung is getting ready to do the same.<\/p>\n 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\u2019t or writing into another app\u2019s space. This means fewer crashes, better stability, and stronger protection against common security exploits.<\/p>\n AssembleDebug \/ Android Authority<\/p>\n There is a trade-off: MTE can slow your phone down a little. As Samsung puts it, \u201cThis can reduce your phone\u2019s performance.\u201d<\/p>\n Code<\/p>\n Copy TextMTE is not applied yet until reboot<\/strong>
You\u2019ll need to restart your phone after turning MTE on. The text includes messages like \u201cMTE is not applied yet until reboot\u201d and a prompt asking you to restart. Samsung appears to be putting this option in the Auto Blocker app instead of hiding it in Developer Options, which should make it much easier for regular users to find.<\/p>\n Don\u2019t want to miss the best from Android Authority?<\/strong><\/p>\n
