Ads are not blocked when on mobile data connection!
AdAway will not work reliably when on Mobile Networks like 3G. You can deactivate that proxy by going to your selected APN (On Android 4: Wireless and networks -> More… -> Mobile Networks -> Access Point Names) and remove the value in the proxy field. Ads in Chrome are not blocked!
