https://us.community.samsung.com/t5/Galaxy-S21/Screen-freezing-after-last-security-update/m-p/3427582#M97940 I finally figured out after all this time that the screen freeze is caused by taking a screenshot. I press volume down and power simultaneously to take screenshots and that's usually when the screen freezes. After playing around with it, I found that doing that when the screen freezes takes another screenshot and I'm able to use my screen again. Not sure what's causing it but it did start after the last security patch for Android 15. Wed, 10 Dec 2025 13:27:13 GMT rjohnson7581 2025-12-10T13:27:13Z
