This happened to me this morning, I was pressing keys trying to silence the alarm and I guess I put it into this accessibility mode (called universal switch). I have a Samsung Galaxy S8+ running Android 8 currently. What I believe fixed it for me I pressed the power + volume up key 3 times in a row quickly I'm not sure if this is exactly what fixed it or what exactly. I was at such wits end that it happened so quick and I was greatful to that I could use my phone. Things I tried that didn't work Pressing the home button 3x Trying to put the phone into emergency mode (I couldn't choose anything on options that had more than 1 item) Going to the settings I couldn't get into the notifications, I couldn't pull them down I couldn't get the phone unlocked due to a password on it Press both volume keys Holding keys Power + Volume keys (up or down) Bixbe key + other keys Telling Bixbe to open settings; it would given my password, but it was still under the lock screen unfortunately. "Hey Google" Biometrics weren't unlocking the phone. After Thoughts There must be some stupid key combination that enables it from any screen... I have a hard time believing that I managed to navigate through screens while my folio case was closed while my alarm was going off and I was half awake. I enabled this once on purpose because I wanted Google Now to make beep sounds when I said "OK Google" I wonder if now it's more easily enabled because I did this before? When enabling it you do get a screen that tells you how to disable it but you won't see that screen after the first time, especially if there's some magic key combination that enables it I'm sure it's different from device + versions.
