there was probaly somthing holding it in place that broke off, sadly, i think that i could fix the buttoun in place with a 3d printed part,also, if it isn't rubber, you also need sp®ings
chech the voleume down buttoun if it is stuck, if not, take it to your nearest tech store and diagnose it, if it is, get the buttoun lubed for it to stop sticking. your trusty tech source, bacon
