What the title says. When it reboots, the screen just turns black without any warning or pop up windows. (Though I think I have seen a very dim flash of a red warning strip across the screen one time when using it in the dark.)
I also have a suspicion that the power button might be failing. I generally have to click it harder for it to lock the screen now, and sometimes it opens up the power menu when I only clicked it once.
Would a failing/stuck power button also cause this rebooting behavior?
Thanks!
Edit: Thanks for the help, guys! I think I’ll get my phone checked for a stuck power button some time. Shame I use it often for the camera shortcut.
No. The power button is not connected to actual power like a simple device. That is just a push button that toggles an input pin on the chip. The purpose is all done in software.
It is far more likely that you have power shorting out somewhere. The most likely culprit is going to be the USB-C connector.
Does the phone get hot when it is cutting out?
No. The power button very much can override the software function by being pressed for an amount of time. It’s mandated by law that the power button resets the phone even if the software is not responding.
In which country is it mandated by law?
Sorry. Was confusing that with the requirement to be able to shutdown a battery powered mobile device, like a phone.
But the fact of the matter is you won’t find a phone that doesn’t reboot when you press the power button (or a combination of buttons) for a few seconds.
