The Firestick device automatically downloads the content you stream so that it’s available in a temporary cache. So, when you’re watching a video it’s actually playing from the cache. Meanwhile, the device continues to download the next chunk of content at the same time. This means that it has to juggle two tasks at once, and this is what sometimes causes buffering issues.
If you happen to finish the first part of the movie while the Firestick is still downloading the next chunk of content, it’ll inevitably show you a buffering message. The Firestick will pause the video while it’s downloading the rest of the content in an effort to update the player.
The problem could be worse if you’re using one of those low-powered and smaller Firesick devices. They’re often short on cache storage space and they don’t have the fastest download speeds. That’s what causes the drawn-out buffering interruptions that they’re famous for.
Now that we understand what causes buffering, it’s time to take a look at the reasons behind the lack of synchronization between the downloading of new content and playback of cached videos.
