I've been messing with different radio's to see which gave me the best signal aswell as the best GPS results. The outcome has become very clear to me and I thought I would share to see if anyone else has these results.
When on 3.39.10 my gps will lock in less than 1 minutes with no adjustments needed to be made. The only extra step is the normal priming of the GPS which I do thru Astrolauncher. I have run other radio's which wouldn't connect even after 15 minutes so this is definetly going to be my radio of choice until something different is presented with the same or better results.
thx for the tip
everyone has different results, even with the same rom and radio. i was using dcd 3.0.4 and radio 3.35.05 for a while and it always worked well. then i did the GPS fix on 3.35.04 and got even better results. then i updated my radio to 3.42.30 with the GPS fix and now my GPS gate locks before my today screen can finish loading.
When I first flashed DCD 3.1.6 I used RADIO 3.42.30 and experienced very slow GPS locks. I recently downgraded to RADIO 3.39.10 and my GPS locks are down to 10-30 seconds (This is on VZW with the "GPS fix" applied).
Thanks for the suggestion guys. I may very well update my guide to tell users to use the 3.39 radio for better GPS locks.
P.S. Can someone post the link for the RUU (even if its the Sprint ROM, I can just steal it out of there), thanks.
Well I tried it and all I can say is WOW. I even tried it on a fresh ROM with no GPS hack for verizon and it locks the first time in about 60 seconds and after that even faster. I actually experienced a 10 second lock a minute ago. Thank a million for posting your results.
Here's my results....
COLD START
2.42.30 radio
Used HTC GPS Tool - Locked in 1.5 minutes
Google Maps - locked 20 seconds later
took 1.75 Minutes to achieve 5 sats
3.39 radio
GPS Tool - Locked in 10 seconds
Google maps locked 5 seconds later
Definately weird....
I'll assume that because I flashed a new radio, that I can consider it a cold boot lock on 3.39... However I didn't initialize the clear memory
I think you guys are using HTC GPS Tool wrong with 3.42.30.
When you use HTC GPS Tool to prime, and initiate with a cold start, you don't have to wait until they turn green to switch to Google Maps. As soon as you see 3+ red bars, open Google Maps and Use GPS. I get locks in under 10 seconds with 3.42.30 even on the coldest of starts.
I don't even use the gps tool just Astrolauncher for iGo and Google Maps.
Well to each his own. Personally I'd rather get the improved signal strength from 3.42.30 while maintaining fast GPS locks.

I think that is key for me, because I thought you had to wait for the bars to turn green before doing anything.
Do you leave the GPS tool open when you switch to Google Maps? Once I get the bars to go green I have been closing the app and going to my GPS software, does it work better to leave both open?
This is exactly what I do...
Open QuickGPS and download ephemeris data (only required every 7 days)
Close QuickGPS
Open GPS Tool
Com4, 4800 bps, Cold Start
Open
Nav Init
Switch to Satellite tab, wait for 3+ red
Leave GPS Tool open and open Google Maps
Use GPS
Once it locks, close GPS Tool
I get locks in under 10 seconds every time.

Kool...
I have been looking for something like this and I have been doing this ALL wrong. I sit there waiting for a green for minutes at a time. I am using tt7
So when I get the 3+ red then I will NOT hit the 'ok' to close the GPS tool but now hit the windows key to open tt7...cool
thx man...
Yeah again, this is only for cold starts too. No need to do this again 5 minutes after the last lock.

forgot to ask...looks you do not do a soft-rest? Also do you always go COLD even if you have used the gps once or twice earlier that day?
No need for soft resets.
It depends on how long it's been since I've used it. If it's been more than a couple hours, I cold start.

How many people do you think are waiting for a green lock in HTC thinking they are not locking?
This would be a great thing to make more visible GC, you may want to post it on your "fix" page. There would be many more believers in your fix if you do. I think that 3.39 is faster at getting an all green lock, but using this method 3.42 gets three faster from home. I will be testing this more. Thanks!
well until today I always waiting for the green but not anymore...may hardest lock time is in the morning so I will see then but by noon I can lock and continue to lock all day. I can lock up to 3am but when it comes to 8am-10a during rush hour I had no luck...but I will see in the morning. I am doing this from one location my home so my position is the same for all the successful connects...

Hi gc14,
I was also under the impression that waiting for the satellites to turn green meant a lock.
I just tried using your method and received a lock on 5 satellites in under 30 seconds. The only problem is that running HTC GPS Tool and Google Maps at the same time causes severe lag. Do you minimize HTC GPS tool and then launch your navigation software or just launch the navigation software?
I highly recommend downloading an app called GPS Status from the market. It downloads A-GPS data from the internet every time you launch it, which helps the process of obtaining a GPS lock.
I open it before opening Maps or Navigation, and it gives me an almost instantaneous GPS lock.
Give it a try!
EDIT: Obtaining updated data works about half the time for me, but it does work sometimes. Hopefully it'll work in a pinch!
If the A-GPS doesn't download auto-magically, go to Menu, Settings, GPS and Sensors, then reset and download the A-GPS data under Manage A-GPS Data.

it takes the same time for this app to obtain a gps lock as the navagation does. 15 minutes to an hour

I had the same issue. I simply use task manager to end gps status after a reset and download and it locks within 2 - 3 seconds after that.
Hoping that 2.2 (either OTA or through ROM's) will fix the gps issues some of us are having.
One thing you can do is change the settings ask that it downloads new agps data if the data is over an hour old. That way you'll get new data pretty much each time you turn it on.
I just "Reset" the GPS in the GPS Status App. I don't "Download". After I do that, I usually lock within 2 seconds. Works everytime.
Good, I'm not crazy. I actually let GPS Status seek out some satellites first, then I switch to navigation. That way I know that I'll have a lock when I open Maps or Navigation.

YAY!.... my biggest upset about the fascinate was the lack of gps success factor... even more than the bloat ware!!!
rooted, zinc'd, voodoo'd and now functioning GPS!!!! all i need is 2.2 and I'll be completely fascinated!
Hey All,
Hopefully you guys can answer this questions for me. I've noticed that whenever I load google maps it will never ever lock onto my position it only uses network location UNTIL I load up a software program such as GPS Test. once I turn on GPS test withing 15 Seconds I have a lock. Once I have a lock I can go into Maps and all is well.
So, is there a problem with Google Maps where it wont lock your GPS position until you use GPS Test? Can anyone shed any light on this subject?
It requires more than just 1 sattelite to get your location. On your lbstest
It will say you got these satellites but not location
Longitude and laditude

Thanks for the reply, but you missed my point. In lbstestmode or other gps apps I can get a lock of 9 out of 10 satellites in less than 15 seconds with great signal strength(over 50).
But if I don't use lbs or some other app before starting google maps I never get a lock at all. Why would that be? Any ideas? So now I have to run 1 program(lbs) before running maps. Why won't google maps lock onto satelites?
Sent from my SGH-T959 using XDA App
I noticed the same thing. I have switched to the new jl4 modem and i don't seem to have to launch gps test first. It seemed like it was something to do with maps caching gps data and gps test not caching.
I'm looking for a program that will turn off stuff like sync and bluetooth and gps and if a program needs gps or wifi or sync it will turn it on use it and turn it off thanks I got a Htc amaze with ics 4.0.3
Sent from my HTC_Amaze_4G using xda premium
That program hasn't been made yet however, GPS and bluetooth will only activate if a program calls for it. Juice Defender will turn off Wifi and 4G when the screen is off. However, it will not turn them back until you power the screen up - or during it's [JD] night cycle - unless you program it to do so.
You'll need Tasker

I haven't used Tasker in a couple of years. Forgot about the program. Thanks for the links to the how-to's. :laugh:
Hi,
my SG Watch 4 (BT) ist the most time of the day in airplane mode.
2 or 3 Times a day i manually turn on Bluetooth to synchronize with my phone.
I am looking for a way to turn on BT automaticly for e.g. every 2 hours for 5 minutes.
Tasker e.g. seems to work only when the watch is connected to the phone.
Any hint for me?
