Any GPS experts out there? Is it the Qualcomm chip that sucks, in terms of sensitivitiy? Is it purely drivers, or what?
Also, has anyone ever been able to TRULY enable A-GPS? I have never seen any evidence of this on my Sprint Touch. I have literally done everything I can to get flawless GPS. Radio 3.37.10, 3.37.15, and 3.42.30. I have tried every ROM under the sun, to no avail.
I used to run the 2.03 PPST before the 2.04 came out, and it seemed to have REALLY quick GPS locks--in under 5 seconds most times, but then after about 10 GPS uses (start/stop/start/stop,) I would lose GPS altogether.
Now, with the leaked/officlal 3.03 Sprint ROM, and the 3.42.30 radio, (allowing PPST.exe to run,) my first GPS lock after a soft-reset is usually about 40 seconds, (which is worse than the 3.37.15 radio.) VERY HOT locks are still about 10-30 seconds... On the 3.37.15 radio, VERY HOT locks were instant---like if I just used GPSToday a few seconds ago...
Anyways, I still lose GPS on the new radio, after a few GPS attempts... requiring a soft-reset. -- In general, I'd say the GPS on this device is TERRIBLE. Other's say they have awesome GPS performance, but then they mention locks "only" taking a minute, or 2 minutes... That's not even usable.
So is this due to the MM7500 chipset, or what? Is A-GPS not really enabled?
All-in-all, I must have been spoiled by my Sanyo M1 on Sprint, because I never once had a lock take more than 5 seconds... A-GPS is the king... because it still works even when I have no cell reception...
If we could get the GPS to ALWAYS lock in less than 5 seconds, it would actually be what I would expect if I purchased a GPS unit... perhaps this is why HTC and Sprint chose not to enable GPS?
Feel free to throw your thoughts on the table... I'm just getting fed up with flashing 20 ROMs a week, trying all sorts of tweaks/programs to get something to work half as well as the majority of all other phones out there...
