This is a known problem of the S5 mini, and there are some fixes found and published on internet. I tried some, but did not have any success. But after that it get even worst and the service replaced something in it. Now its not so accurate again.Anyone else noticed GPS accuracy isn't that great, compared to, let's say, the S4 mini? Not sure if it's ROM related though. I notice much more GPS spikes with my Runkeeper APP, than with the S4 mini. On both phones I also use(d) the "GPS Status" app, to always download most recent assisted GPS data...
Otherwise great stable ROM by the way! Thanks for the work!
