As the title says. The buttom fell off randomly, i released after a few seconds of it going and managed to locate it on the floor. Just the metal piece fell off, to look at the device it is black and feels like rubber, jut so you understand whats actually fallen off. Can i reattach this? And is the device currently still water resistant (I think the rubber is the watertight gasket)
If you could post pictures we could probably give a clearer answer. But if it looks the way I think it will I don’t think you’ll be able to reattach it, even if you took the case apart. (Don’t recommend doing this if you don’t have to, very easy to break the back glass, plus it breaks the watertight seal.) If the button fell off he side I’m going to assume that the little bits of plastic/metal that hold it inside the case have broken off. If there are any little nubs sticking off either side of the button you could try inserting the button edge first and see if you can get it to pop back into place. Outside that you may be out of luck.
Same happened to me and I had to download an app called Volume Control
