How and why did device key string turn my Wi-Fi on when it doesn't have permission to do that?

Android Central Question

In my Wi-Fi control history it said my wifi was turned on by devicekeystring today. I previously revoked all permissions for changing my Wi-Fi settings but I double checked anyways because sometimes my phone does weird things. However the settings said they had no permission to control my Wi-Fi still however it did turn it on anyways.

I have the same question. I have a new Samsung Galaxy S23 Ultra. Today it suddenly said that Wi-Fi was turned on by devicekeystring. I can't find anything about what this app is, what it does and why.

Right. But I still don't know what this app does and what it is for. Temporarily I went into settings>apps, turned on show system apps, went down to DeviceKeystring and disabled the "change system settings" permission.

I did a search, but couldn't find anything. But it's definitely a Samsung system app.

When you use any modern piece of tech, you have to accept that there will be many system apps that you (nor I) will understand. There are lots of components to the system, and these kinds of things aren't necessarily going to be laid out on a website for a layperson to understand. Think of a Windows PC -- there are literally hundreds of thousands of system files that make up Windows, and the average person is not going to understand what the vast majority of those files are for, nor will they be able to find adequate details using a web search.

I know what a Device Key String is. I don't know what the DeviceKeystring app is. It might be related to Settings>Connections>Wi-Fi>(3 dots)Intelligent Wi-Fi>Turn Wi-Fi on/off automatically. But am hoping someone knows the answer if that is what DeviceKeystring app is for.
