Not annoyed by Facebook, but by the way the Facebook app read and write to the system folder.
It creates “com.android.facebook”(or similar) and “Notifications” folder right in the root directory. That “com.android.facebook” supposed to be in “Android” subfolder. It seems like Facebook app does not want to compliant with the Android OS.
Does anyone find this annoying? For small and petty reasons, I uninstalled the app. (After all, I am not a regular Facebook user)
