I am using this application from 3 years has lots of mejor problems hence I didn’t use facebook app often rather I use website The app has good concept and has good layout and design but it use lots of data it take time to load it It shows lots of post which 8 am seen in past The mejor problem is it use lots of data and the battery drains faster The app has lots of features now as you know but when you start camera direct from app it takes time and picture taken is also not good for uploading videos it take lot time The facebook gives the update in 15 to 20 days frequently and its large one so why don’t give update once in month they have improve Due to facebook lots of junk file and cache files stored in mobile The app is useful but they have improve the app.
