Thousands of devices stopped working.

[Bill_Green]

I am the MD of a UK company that provides equipment to the taxi trade (similar to Uber). We have thousands of mobile devices out in the field but just recently most of the older J1 and J3 devices in service have suddenly seen their GPS fail. To our knowledge, no updates been received that may have caused this and a factory reset has no effect. Running diagnostic apps shows multiple satellites in view but all with missing data in the NMEA strings.

Any help you may be able to offer on this problem would be appreciated.

Well, it seems to have fixed itself. GPS is now fine on both of my J320FN s

We've found a temporary solution and posted it on StackOverflow. Follow the link. We are still looking for a definitive solution!

Before changing gps.conf I would check that it is still needed, i.e. that GPS still doesn't work. Google appear to have fixed whatever server was misconfigured and GPS now works perfectly well on my J320FN (J3 2016) phones.
