I have mentioned this before in this thread. When I was trying out GDX V23. GPS doesn't give proper location on Google maps. Same prob with GDX V25. Now you might say it has nothing to do with the ROM as you guys said before, but how come the same modded Google map Works properly and gives the correct location in other ROMS I've tried?
Google Maps (the GENUINE one) on GingerDX v025 (on Stock Kernel) pin-points my EXACT location within a 15m error margin - no matter where I fire it up to have it tell me where I am. EDIT: Actually Maps ALWAYS worked reliable for me from GingerDX v009 (first version I used) up to the current one.
I've no idea why it doesn't work for some, but it sure IS connected to some odd problems caused by star constellation, moon phase and humidity. In other words: Logfiles or figure it out yourself what causes the problem.
