My younger sister has an Amazon Kindle Fire 10", and according to xfinity it uses more data than the entire rest of the household combined. This morning I opened the xfi app, and found that this trend is continuing with 7 hours of network activity by noon, however, her tablet "freetime" doesn't allow her to use the tablet till four in the afternoon!
What I am wondering is, what is the best way to scan/monitor/check for, foul play or a malfunctioning app? If Xfinity is to be believed, this "glitch" has used over 400 GB of network data in 10 days! (I am a power-user and am ready to use-and-abuse all my developer rights to figure this out)
