I think i have tried any possible solution out there. I went over any possible internet forum and site. Really.
I have EPO enabled with automatic download. I have AGPS enabled. I used FasterGPS, GPS test, GPS status and all other kinds of similar applications. I have rooted my device, tried endless settings in the gps.conf file, etc
I have Star N9500 device.
Its not that i do not have a GPS reception. I do !!!!
And i can also use maps navigation quite well !!!
The only problem is that in order to get a fix on satellites in a reasonable time i always have to go into engineering mode -> YGPS -> Information and download full EPO. Only by doing that, i can get a normal TTFF time and get back to the navigation application. Otherwise, the navigation application (like Waze) never succeed to get a fix by its own (at least not before 10 minutes are past).
I have noticed that in engineering mode->Location Based Service->EPO there is a parameter called "Update Period Setting". Its default value is set to 21600 minutes. I don't know if it is relevant, but i tried to set it to lower value like 360 minutes, but it keeps on returning to the default after restart the device. Does someone know how to make the value permanent? Is it relevant at all?
HELP please. I am starting to give up
