This app consist very much space in comparison to facebook lite and do nothing special for the users so I think immediately you uninstall this app and install facebook lite in place of this so you will be feel more comfortable due to this and also there is another big problem in this app is that sometes it cannot show the online people properly it shows the fully blank corner page when I open it so I suggest you to decrease its size for better downloads I hope you will do it and other ramaining features are good
THANK YOU
