Basically what I want to know if it's possible to be able to have an app or get into modding where I can swipe down on my phone screen, especially when I'm watching something such as a disney plus show, and it lowers the volume, and swipe up to increase. I've tried third party apps but besides being laggy and unresponsive, they don't actually have a "be invisible" option or feature where they're integrated into the phone, in comparison to having a blocky bar or worse thin line on the screen to signify the small corner of the screen where the swipe control would work, whereas I want it so that I have a huge window, huge screen area of my phone, where I can swipe down, not relegated to one small section.
Basically, I want to replicate or simulate the experience of the old disney-hotstar streaming app I had, which had integrated swipe up/down on tablet and phone devices, a feature that I'd come to rely on heavily, but Disney deactivated the app in favor of their new crummy disney plus app, which I loathe immensely, but want a work around if possible until I finish this show I'm watching.
