Can bug fix be requested from ?

When a bug cause is not jQueryMobile（For example, HTML5(Platform) or Operating System or a mobile device is bug cause）, Is jQueryMobile corrected? Can jQueryMobile be corrected? Can an avoid measure be taken out?

Can bug fix be requested from, for example, Apple Inc, Microsoft Corporation, Google Inc, Nokia Corporation…

Or is it necessary to wait until it is corrected?
