My phone was fine when I woke up this morning. But my Peel Remote app had put a floating widget on my screen ever since the last update, and today I clicked on it to get in and try to remove the annoying thing. I didn't get very far because my touch screen immediately became unresponsive. The phone wasn't frozen, but I couldn't do anything from the screen.
My go-to solution for problems of quirky machine behavior—as it has been since my PDP-12 days—is a reboot. So I pressed the power switch. Samsung users will immediately see the problem here: doing a reboot that way requires confirmation from the touch screen. Which wasn't working. I tried holding the power button down for several seconds, which works for many devices, but that had no effect.
One obvious solution would have been to remove the battery, but I didn't really want to do that with the machine powered on and (mostly) working. So I turned to Dr. Google—definitely not a solution from my PDP-12 days. I found several suggestions, and a number of people who had had the same problem with Peel Remote, even a year ago.
The easiest and most reliable solution seemed to be to press the volume-down and power buttons simultaneously for several seconds (variously suggested from 7 to 15). I'm skittish about such things, and did not want to find my phone suddenly in safe or download mode or worse, but what else was there to do? Call customer service? I've done that before, and have been leery every since, because they recommended a hard reset (which would have wiped out all my data) for a problem Dr. Google solved with no pain at all.
So I pushed the buttons.
The happy ending is, it worked. The phone rebooted. The touch screen began working again. I then turned the phone off and back on again, because ... well, because I learned a long time ago that that's a good policy after computer troubles.
I'm telling you here because I'm really telling myself here—I know from experience there's likely to be a time in the future when I'll say, "Wait, I know I had that problem before ... what did I do to fix it?"
