Since when the Facebook mobile app has launched I have never found any bug free versions, every second day there’s a new update giving minor bug fixes but still they are unable to fix the bugs.
Just the app size changed from 20mb to 100mb but not bugs.
The crap app also take every data from the device and keep the records of where you go, what you love, what you do. To be surprised how they get my every activity even when am offline.
