I have found on Reddit the link to it https://www.dasung.com/h-col-112.html but after installing, I didn't find any app; only the DASUNG Shortcut was registered which simply clears the screen by toggling the inverse mode.
I'd appreciate if you could share whether you have noticed any changes after installing it. I guess there is a difference, but I'm seeking confirmations.
To give you more context, I have a personal device and a working one, and it order to install the software there, I'd need to raise a request to approve such software. However, if that installation package simply adds a Shortcut, it makes no sense to even try that.
