To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Contrary to Kellz's review, this app certainly did not come pre-installed on the kindle fire. As most of us know the kindle fire came with nothing more than a shortcut to facebook mobile (hence the reason it opened the browser...) this is an actual legitimate facebook APP, works just as well as you could expect, no issues so far. This is a reasonable alternative to those of you who are still running Amazon's android 2.3 gingerbread factory operating system and have side-loaded the facebook app from Google play (as it comes with auto updates instead of manual side-loaded) or those of you still just using facebook mobile and dislike it!
