First of all: Partially Success ! Deleting /var/lib/ubuntu-location-service/config.ini and restarting device seems to unlock the GPS-Functionality at all !
A first position fix has only been available after connect to WIFI Network. SensorStatus shows continously updated position data. Also UNAV has been able to locate the correct position. unfortunately after two or three minutes GPS falls asleep and stops updating position data in SensorStatus. Also UNAV stops updating position data. After restarting SensorStatus and also restarting UNAV refreshes position data. Restarting UNAV only leads to an error report by UNAV: No access to GPS. The output of ubuntu-location-serviced-cli --bus system --get --property visible_space_vehicles is also satellite data and additionally: Attempted to unregister path (path[0] = com path[1] = ubuntu) which isn't registered But I don't know what that means ! My general impression: Perhaps the GPS-problems may be caused by incorrect interaction with the power-management software -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to location-service in Ubuntu. https://bugs.launchpad.net/bugs/1489329 Title: MX4 GPS doesn't work at all Status in Canonical System Image: Confirmed Status in location-service package in Ubuntu: Confirmed Bug description: When using location for navigation, GPS is essential. Location can also be based on Wifi or phone network, but accuracy for that is insufficient for driving/geocaching/any application except nearby restaurants. I can currently only get a location based on wifi / phone network. If I disable this feature, I get no location at all. Not after reboot, not sometimes, not ever. Trying to do: Navigate using GPS and/or network What I expect: Accuracy is high with all location services on. It decreases slightly when network based location is switched off. It decreases sharply when only GPS is switched off. What happens: Accuracy is very low (30m - 2000m) with all location services on. Location is impossible when network based location is switched off. It doesn't make a difference if I switch the GPS on or off. This may be a hardware issue, and I'll probably be sending in my phone (MX4) for check/repair, but that would mean missing my phone. I'd much rather troubleshoot myself. I already have location test and sensorsstatus to monitor this, but I want to know more about if the chip is functioning. Which logs are relevant? I've thought about flashing android on and seeing if that helps (which makes it a software issue), or doesn't (which makes it a hardware issue). Is there an easier way to get an answer to the software/hardware question? Thanks!
