A. Restarting your Fire Stick does not automatically clear the cache. However, it may indirectly help with cache management in some cases. Restarting your Fire Stick can clear temporary caches associated with the currently running apps. When you restart the device, it closes all the running apps, and as a result, any temporary data stored in the cache by those apps is usually cleared. Restarting a Fire Stick may also clear some system-level cache. The Fire Stick itself may perform some housekeeping tasks during startup that could include clearing the system-level cache. However, this is typically less effective at clearing significant amounts of cached data.
