I’ve activated the Agps and the EPO to try and improve the GPS and wanted to check that it won’t be eating through my data allowance? If i have my wifi and data turned off it can’t be used, is that correct?
Also I’m assuming the blue floating circle which appears on the screen when ever i wake the phone us is telling me how much data i have used? Is that correct and if so is there an option to turn it off?
As for the information on your data usage which appears on your lock screen: Go to Settings > Data usage > [your network]. There is a slider which says something like “View on lock screen”. Switch this slider to off.
As for aGPS: This can’t be used without data, concerning EPO, which is a file containing the positions of the GPS-satellites, I think this also gets downloaded through wifi. But there have been known issues with this download process. Consider downloading the FP1-EPO autodownload. (either you choose to download F-Droid which is an open source app store (just like Google Play but entirely open source software) or you download the apk file only)
