I activated Universal Switch once because I wanted to try it out but I soon found out it disabled my screen and it was unresponsive to my touch and I was unable to do anything. So I waited for the battery to drain hoping it would be able to disable itself. It didn't. After fiddling with it for a while, I found a way to turn it off using a mouse and turning it off in the settings but after a while, it turned itself back on. So I repeated the step with the mouse and furthermore I disabled the switches so it no longer turned on automatically. However I found that didn't solve the problem as now it would pop up "To enable Universal Switch, tap settings and add at least switch." every few seconds. I can't figure out a way to fix this. Please send help.
(Also the pop-ups pile on each other. If I leave it for a while, I have to click cancel multiple times as they seem to stack on top of each other.)
