I have a nexus 5 phone that was sitting happily in my bag yesterday. However, when I took it out there was a 280mb data spike from Chrome. I have "lite" data enabled and have my applications and OS set to only update on wifi. I called koodo and they offered no suggestion on what might of caused this or how to prevent it from happening again, only said that it was very strange. Can someone help me??? As someone who uses roughly 300mb a MONTH I can't understand what happened and I don't want it to happen again.
