Picked up my tablet this morning to check maps for some information and noticed that my wife's phone was showing its position on there , it didn't yesterday ! So I checked my Google account and found that all my carefully switched off data collection information had been switched back on , checked the wife's and so had here's! Also the Nvidia shield didn't want to play any apps until I had changed the DNS settings , it was working just fine yesterday on the original settings, so if anyone else is having problems check your google account settings .
