This version of facebook app takes lot of memory for installation in the mobile.
This app is good to use but most of the times it crashes, it restarts or suddenly stopped.
After giving it so much storage space it does not perform normally and this app gets updates in 4 to 5 days which is more memory taking thing.
I think instead of this version the facebook, facebook lite is so good and stable it does not have very attractive interface but it works very fast and smooth.
