A few days ago I broke my Galaxy A50 and the screen is all black with some colorful stripes, unresponsive to touch. I decided to not get it fixed since it would be cheaper for me to just get a new phone. However, I just got woken up by a very loud alarm coming from the broken phone and I can't even turn it off since I can't see anything on the screen and it doesn't respond to touch.
How can I turn off the old device completely? I suppose it would be some kind of key combination, but emergency mode wouldn't work since, as I mentioned, no vision, no touch.
