I have a Samsung Galaxy S4 with a dented/stuck volume button (causing any attempt to boot to end at the screen that asks whether I really want to install a custom OS because the smartphone perceives volume down as pressed).
I am planning to dispose of that device after getting (read: copying and wiping) some data from its internal memory.
As replacing the button costs a lot (both at the official and at other repair shops), I am considering just removing the button.
Will the smartphone work (and keep working for an hour or so) without the volume button? I am wondering whether anything in the system will notice the button is missing and refuse to boot. Also, an employee at one of the smartphone repair shops I went to claimed humidity would enter the smartphone through the opening, and anyway, the repair shops outright refused to remove the button without replacing it1.
1: Presumably because then, I'd pay less. I will remove the button myself, if I find no-one to do it for money, though.
