GPS and Cell location are working. I tracked my location
history and find out that the issue occured with an update
at the end of march. Unfortunately i can't say, which nightly
i installed before and after it was not working. I only can say,
that i was running a cm11 nightly before 03/26 and the wifi location
worked. With an update available at 03/26 no wifi location was used
anymore. In this time i updated the nightlies once a week (may be two)
using cm-updater ota.
I also tried a clean install of the 2014-04-17 nightly on a newly
created SS rom slot 1 --> didn't work.
I read that someone also described this issue in the dev-thread but there
was no real feedback. Does anyone know, if this issue is already known to the
devs and if thy are working on it?
