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 let you enable it.<\/p>\n<p>This might be about to change. Some strings we\u2019ve spotted in Samsung\u2019s Auto Blocker app suggests that One UI 9 could let users turn on MTE with a simple switch.<\/p>\n<p>Code<\/p>\n<p>Copy Text<strong>Enables memory tagging extension<\/strong><br \/>\n<strong>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&#8217;s performance.<\/strong><\/p>\n<p>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. Now it looks like Samsung is getting ready to do the same.<\/p>\n<p>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<p><img class=\"e_Wg\" decoding=\"async\" loading=\"lazy\" sizes=\"(min-width: 64rem) 51.25rem, 80vw\" title=\"memory tagging extension\" srcset=\"https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension.jpg 1080w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-29w-64h.jpg 29w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-1000w-2244h.jpg 1000w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-642w-1440h.jpg 642w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-481w-1080h.jpg 481w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-385w-864h.jpg 385w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-169w-380h.jpg 169w, https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension-535w-1200h.jpg 535w\" alt=\"memory tagging extension\" src=\"https:\/\/www.androidauthority.com\/wp-content\/uploads\/2026\/04\/memory-tagging-extension.jpg\"\/><\/p>\n<p>AssembleDebug \/ Android Authority<\/p>\n<p>There is a trade-off: MTE can slow your phone down a little.
