My addiction isn’t the phone, it’s the computer, Youtube specifically. And I can’t use greyscale due to creative Photoshop work. Kingdom to whomever solves my problem.
it is much easier just to set up accessibility color filter and then toggle greyscale mode with Winkey+Ctrl+C and you can keep using your apps without installing anything
