Facebook Home, Facebook’s Android homescreen takeover, has been available for just over a week. In that time, we’ve seen the app take on a barrage of negative reviews.

But people are still downloading it and trying it out. As of today, Facebook Home on Google Play has surpassed 500,000 installs.

We don’t know the exact number of installs, as Google Play only gives us an unspecific snapshot of the numbers. Right now, it says that the number of installs is somewhere between 500,000 and 1 million. The Next Web noticed that Twitter users noticed the jump from “100,000 to 500,000” to “500,000 to 1 million” some time on Sunday.

500,000 may seem like a small number of installs, considering that Facebook has over a billion monthly active users and that something like the Facebook app has between 100 million and 500 million installs. But in a week’s time, to be working its way to a million installs, is pretty good for Facebook Home considering it’s only available on a handful of Android devices.

Still, the news isn’t nearly all positive for Facebook. Facebook Home is still suffering from poor user reviews. Last week, we told you that after just 3 days on the market, Facebook Home had sunk to an average rating of 2.4 out of 5 in the Google Play Store. At that time, 47% of all reviews awarded the app 1 star.

Now, at Facebook Home surpassed 500,000 installs, the negativity is growing. The average rating has fallen to 2.2 and 1-star reviews now account for nearly 52% of all reviews.
