I was trying to use touch block with endless alphabet with my 1 year old. While I was trying to set up what area of the screen to touch block, he hit something and now the top of the the screen is blocked from touch. It somehow has entered "kids mode" that I have never used which is preventing touch block from being disabled. Power, volume, and Bixby keys are blocked. So my phone is essentially blocked from all ways to exit the endless alphabet app or kids mode (whatever that is) and turning off.
