An operating context (OC) for an application is the external environment that influences its operation. For a mobile application, the OC is defined by the hardware and software environment in the device, the target user, and other constraints imposed by various other stakeholders, such as a carrier.
This concept differs from the

Example
Here is an example of one device, with one operating system, changing its operating context without changing the OS.

Any applications running on the phone will run in a new operating context, and will often have to change functionality to adapt to the abilities, and business logic, of the new carrier. The network, spectrum, and wireless protocol all change in this example. These changes must be reflected back to the user, so the user knows what experience to expect, and thus these changes all change the

Hardware agnostic context
Situations exist where one can program in a context, with less concern about what hardware it will actually run on. Examples include Flash and
Android.
Unfortunately, it also quite common that code in a hardware free context will see hardware specific bugs. This is common with software written for, that interacts more directly with,
