The bottom right corners of my phone have this annoying shortcut and I cant shut it off. I read something about es explorer. My Samsung s9 plus doesnt have that. I want it gone
Welcome to the forums. That sounds like the 'swipe' menu included in many different apps. The usual suspects are ES File Explorer, photo/video editors, antivirus, keyboards or any app by Cheetah Mobile, GO out DU.
There is an easy way to identify the culprit if you enable the developer options and check the running services while this menu is opened.
