After installing the latest May 2023 update, the Galaxy S21 randomly reboots. This guide will show you how to fix the problem. One of the few companies in the market that offers up to 5 years of updates [4 years of OS plus one more year of security patches] is the South Korean giant. These patches are typically rolled out to enhance security, improve performance, and fix underlying problems. Unfortunately, that doesn’t always happen.
There have been numerous complaints about the Galaxy S21 randomly rebooting after installing the latest May 2023 update. The phone freezes before powering off and then restarts a few seconds later. Moreover, this tends to happen multiple times throughout the day. As a result, there is a nifty workaround that should help you resolve this issue. Let’s take a look at it without further ado.
