  How to monitor the amount of data traffic?  




Is there a way I can monitor how much data all the individual apps use? All the traffic monitors I have found only show the total amount.
There's a program on Google Play called Network TrafficStats Lite that does this in most Android versions.  If your phone happens to be compatible to Ice Cream Sandwich, consider upgrading as this feature is built in.
