Currently I have an HTC M8. I bought the AT&T version and converted over to GPE without a hitch.
Lately I've noticed my GPS apps have not been working. So, I did some research and downloaded GPS ToolBox to try and refresh the A-GPS Data. When loaded, I noticed that it would not lock on to any GPS satellites. It could see 15+ (which i think is pretty decent.)
I did a complete restore after making a backup to no avail. I am not sure what could be the problem, is there a best route in order to troubleshoot this?
I can provide further detail if needed.
