This is a demonstration of Android GPS' capability w/o cellular network and AGPS assistance.
Based on my experience with the Android devices that i have mao ila performance
GALAXY S2 - 1-3 minutes
Galaxy S WIFI 5.0 - 3-5 minutes
Galaxy Mini - 3-10 minutes
Galaxy 5 Europa-3-10 minutes
i must also emphasize nga although my s3 clone runs on ICS 4.0.4 and iyang time to view and lock to a satellite is suffice to say...forever. Comparatively speaking
Now ang akong Samsung B7610 OMNIA PRO WM 6.5 - 5-10 minutes despite being GPS tweak more than my Android devices.
i used my Android phones as GPS receivers for the following PC programs
Garmin Mobile PC
OPenCpn
Raytech Navigator
Transas 4000 ECS
And GPSgate to open multiple COM ports.
