The recent update for the Facebook applications made many android users annoyed with the new Facebook icon that is automatically added to messenger and camera. To many, it was completely violating users privacy by accessing internal system files. However those who have their android devices rooted know a way around to fix this Facebook icon and to get back the original icons for messenger and camera.
