Ovi Maps gives up finding GPS lock too soon

It turns that Ovi Maps will stop polling the GPS after 30 seconds of app
minimized or display dimmed, due to a power management policy. This
gives the impression to many end users that "after one hour still didn't
get a fix" when actually the GPS has been searching only a tiny fraction
 of that time. Quick fix: keep Ovi Maps awake while searching
satellited.  A proper fix is in the plans in a future release.

Can't get a GPS lock with several satellites at view

If you really want to get into proper testing, install the
location-test-gui app, that will provide you data about satellites at
view and signal strength. So far the results are quite decent among the
people that has provided test cases. In my case after dozens of tests in
several conditions I get locks in 1-3 minutes in about 80% of cases.

There are already some overlapping threads open in Talk in addition to
these bug reports. If you want to analyze or discuss further please use
