What happens if the memory of the phone is full?

Let's assume that I have not defined any `stalePeriod` or `maxNrOfCacheObjects` and the cache in the phone is full. What happens then? Will nothing more be loaded? Or does the app crash?

Start by tracing how the cache behaves when no stalePeriod or maxNrOfCacheObjects is configured and the phone's storage is full. Confirm whether downloads stop, cached objects are evicted, or an error is exposed, then document the observed behavior and any relevant limits in the project documentation.
