AlpineQuest & OfflineMaps

I've been using Alpine Quest (AQ) on my Samsung Galaxy SII (GT-I9100 running Android 4.0.4) for over a year. All worked well initially. However, I have recently been experiencing problems with the GPS failing to lock onto satellites. With the phone outdoors with a clear horizon, the GPS position window indicates "Source GPS (0/n sats)", the lock button is red indicating no lock obtained, and the bar display showing n satellites detected (with corresponding number of black bars). After a short time (10-20 secs), the bar graph resets to no bars displayed, it builds up again to n satellite bars, but no lock, and resets again. This can go on indefinitely.
I have checked the phone GPS system with another app (GPS Test) and this will get a lock outdoors using 6+ satellites in a few seconds!
Interestingly, if I turn ON the AQ Location Tracker function, the GPS locks in within seconds, and GPS behaves perfectly OK for as long as the Location Tracker is enabled - but not without it.
I have un-installed and re-installed AQ - same issue.
Any ideas?
Thanks in anticipation!

Hi and thanks for this report.
I honestly cannot see any possible cause to this issue right now, especially since the Tracker seems to work fine although the same usual method is used. But I'll make some research.
Have you tried to select the GPS as location source from the AlpineQuest location settings? In the GPS details view, click on the top right icon and select "Outdoor GPS" instead of "Auto".
Also, have you tried to restart your device (sometimes it fixes weird behaviors).
Also, be sure to use the last version.
Please let me know
Sorry or this disagreement,
Best regards
