Your Navigation Experience using 640 ( Any issues)

[shan678]

hi,
I'm using my 640dual sim for about 4 months & everything working fine except the gps. Recently GPS won't lock to satellite signal in outdoors , tried both offline and online mode also tried some soft resets. it's showing accuracy about ? 2 km, tried different navigational apps ( incl. default Bing maps). Actually GpS was working fine for about first 3months, then issue started.

so , is there any one experiencing this kind of weird things or write down your Experience ?

Sometimes I have the same problem. One day I did not have gps for about 7 hours.
If you have bad accuracy, the localization is based on wlan or gsm. Try App "Tools Hub", it shows which type of localization is active.
Best way I have found so far is to always activate a data connection before starting localization. You can switch off data when gps is found.
