Bests & Worsts Reviews from Amazon

I only downloaded it because facebook was no longer allowing me to check my messages on my tablet without it. And I'm regretting it. Since downloading it, my tablet is been freezing and crashing. When I receive a message, a tiny icon of the sender's face appears on my screen above ever thing else and will not go away, even if I read the message until I mute the message. The appearance of the icons coincide with the moments my tablet starts to run slow and freeze. I'm going to remove the app and let everyone know not to expect a response to any messages on facebook until I am on my laptop computer.
