Which ROM are you using?

I'm using cyanogen mod 6.1 stable

Download a GPS app. There are a few on the Market. Search for "GPS status".

The same thing happens to me, I dl GPS status and whenever you loose the signal go to GPS status ( PARK FIRST IF YOU'RE DRIVING BTW!!) -> Tools -> Manage a GPS --> Reset , then re-download GPS assistance data. Then go back to your GPS app and it should lock-on again.
It is a major pain in the ass, but it's one of those trade-offs for having Froyo on a phone that was not designed for it and giving Sprint the finger.

Thank you, downloading the app.

this may be unrelated but IF you are using one of deca's kernels try enabling cfs tweaks in the batt-cfg, that helps my gps lock way faster and much stronger.

Hello, Having GPS issues as well after I rooted. I am running 2.3.2 with Cyan mod 7 on Sprint HTC Hero. I get GPS signal for about 2-3 minutes then lose signal. I have tried Google Nav and Map Quest. I have installed GPS Status and GPS will connect when I do the steps above through GPS Status, then I lose signal after 2-3 minutes. To be honest I am new and do not know much about the kernel. It reads 2.6.29.6 aospGBmod. Any help would be appreciated. Thanks!

GPS can be touch and go with the CM7 builds but most of us can go at least a half hour or more with a lock and no issues. Your kernel is the stock kernel for aospCMod. There are several other kernels you can use, namely the 43 and 589 kernels by Deca in the development section. Download one of the kernels and after you flash the ROM and gapps, flash the alternate kernel and see if it helps with GPS.

I gave my GPS an extended workout yesterday. Only issue I had was a reboot after about an hour and a half, and I think that was because my phone was getting warm. No lock loss, it was accurate, no problems. I was on cm7#18 at the time and using nav.

Thanks Anthony. Flashed to 589 and it is a little better. Plus it was sunny here this afternoon so I am sure that helped a little.

No problem. We'll see if the new builds can finally put an end to the GPS problems.

Microphone DIES in the middle of a call!

This is an extremely annoying issue! 95% of calls are "dropped" because people suddenly can't hear me anymore! I can hear them, but after a few seconds they cant hear me... Anyone else having the same issue? Any possible fix perhaps? I haven't found a single reference anywhere.
Also, would this be a modem related issue? Maybe flashing another one would help? If not the modem, what then?
I have a rooted captivate with stock froyo. I've been through the cognition froyo kernel, speedmod and overstock. I also know that the problem stands in cognition 4. The problem has been there since purchase. I bought it from ebay and do not live in the States, so going through AT&T is not an option.
Thanks in advance!

I've recently started having this as well intermittently after about 5 minutes on a call.
I'm on Mosaic V, Jk4 modem, was also happening with Kc1. I just updated to DC 3.0 kernel last night, so we'll see.
Personally I'm thinking AT$T is 'upgrading' the network, but is pretty annoying issue.

Thanks for the reply! I'm from South America... no AT&T here... I believe it must be Captivate related... Anyone else having this issue?

Since u r running a stock, rooted froyo... u could try the latest i897 modem, KF1.
I know it is from the leaked i897uckf1 gingerbread firmware, but u could give it a try. Other than that it may be ur network or a hardware issue.

Happens to me quite a bit. Took me a while to realise the screen wasn't sleeping and my face was pressing the mute button
So now when three other person starts saying "hello?" I always check my screen...always muted.
Maybe your issue, maybe not. Good luck!
Sent from my SAMSUNG-SGH-I897 using XDA App

I'll try other modems, but somehow I don't think that'll do it...
And I'll keep an eye out on the mute thing, although that can't be it either, since it happens while I'm on speaker as well... I used to try using the speaker and keeping the screen alive and it would still happen...
Anyone else?
Sent from my SAMSUNG-SGH-I897 using XDA App

In case anyone might ever find this info useful, Cognition 5 v2 fixed this. I am now on the ICS rom from team ICSSGS and the problem remains gone. It was probably the modem in the different roms that did it...

try another kernel or phone.apk, i dont think it's modems problem

[Q] [ICS] What radio works best for gps in Scandinavia?

Im having trouble keeping satellites locked, not having a lock/getting a fix. Any hjelp appriciated.

I also have problems with GPS. However it also seems my compass is not exactly correct and unstable. There seems to be some correlation. How accurate is your compass?

Haven't tested compass yet.
Progress with gps testing:
Tried several radios without wiping the cache first (no help with gps, wifi&data ok)
Now using nexus radio kb3, seems to work , have to test some more
KB3 (and KF1) also fixed the "always roaming" problem.
To get kb3 to function, had to (wipe cache +)flash kf1 first, reboot, (wipe cache+) flash kb3
At this point, the key for successful gps is to wipe cache prior flashing radio (modem)

Hi, tried your way also but no luck so far. Still think that the compass is of influence. Sometimes GPS works and then suddenly compass becomes unstable and is deviating and at the same time the GPS looses fix but still has satellites in view. I am getting desperate. will try some more.
Btw I am on titanium rom

ok, too bad . I'm not totally satisfied in the way things work just now but at least i can drive with waze on for 10km (the longest i drove today). Tomorrow more test while driving to the cottage almost 300km away.
I have had it working on some older versions of ics roms, but really don't want to go back there..

Try JVK,JVT,JW4,JVU modems (from Rom Manager it's easy)
Toivottavasti joku noista toimii kunnol myös gps:s!
Muute, lisää mut google talkis [email protected]

Tried. Only with some luck.. GPS gets fix, keeps it for a while then loses fix and doesn't seem to get it back. Sigh.
Think I'm going totally stock or Darky's and test there. And then if things work like they used to, come back to ICS roms.

I'm getting good results with JVT. GPS locks pretty well( tested on bus yesterday).

All modems worked as badly.
Then I changed kernel to semaphore and was able to drive 160 km with only few times losing fix.
More testing needed though..

nice, try also glitch kernel=)

Hi!
I had tried different modems but none of them worked so the only solution I found was to open up my SGS and then do some hardware fixes....had to bend the connection "wire" of GPS. Now the contact between GPS and antenna is good, so this means I get the satellite lock in few second, even indoors!
Just search Google or Youtube and you will find how to do it.

Cleared all GPS stuff with GPS aids (yes I payed 2€ for it but was getting desperate)
and now it has been working just great for about 4 days.
I also flashed another ROM prior to clearing, and it (gps) worked ok after the flash. I'm not sure which or both did the trick but now it's working..
I'm currently on slim ICS and my modem is JW4.

GPS AIDS is a great app to improve your signal.in settings u can NTP server,its usually set to world or north America.change to your region.this will improve your signal significantly.

phone constantly resetting it self!

recently my phone has been resetting it self all the time unless its doing something like playing music.
and every time it retests by it self the battery goes down a little bit.
i also cant make a call not even an emergency call! after it resets because it seems to loose all service but if i plug in a the charger i get service again and it wont reset.
im pretty sure its not software related because i haven't flash a ROM in a while and it started on a week ago or so.
im thinking it might be battery related mainly because if i take off the back cover it cam barely stay in.
but what you you guys think?
also im on cm9 if that helps at all

Try returning to Stock ROM or try different ROM

GPS suddenly barely working

Hi all,
Strange issue here. My GPS performance has always been great, but a couple of weeks ago it has suddenly bexomevunusable. Google navigation looses my position constantly and is extremely inaccurate. I downloaded GPS test and my accuracy is never below 150 feet or so.
I have tried factory resetting the phone and even tried installing rocket rom, no change.
Any ideas?
Sent from my GT-N7000 using xda premium

what rom u on?

check your kernel version.. lpt is known to be stable .. different rom use different kernel.. could be your kernel issue

Thanks for the responses, I first had issues under LPY, the thing is...I had been running it for over a month no issues, the GPS just started acting up one day.
Now I'm on the latest rocket rom, which uses a different kernel. So I'm having the issue with two different kernels.
