I just noticed that also. It's really off. It was spot on before the update. Anyone else?

Yes my device has seemed flawless until driving home tonite and the gps showed tight link but navigation was way off because it had me jumping around about 2000m off actual location.

I literally just drove to Boston and back. Gps is accurate as it can be. No problems here. And I'm a cab driver so I use it pretty often.

I am providing this link and you can decide yourselves what you want to do. According to the thread, the S4 is not listed under the "supported phones" list, however, the OP of this thread I am listing states that if you Email him, he will consider porting support. It already works for the S3 and many other devices so it shouldn't take much if anything to make it work with the S4. I suggest you read the entire thread before trying anything or asking questions. Maybe this will help:

You might also consider an App such as "GPS Status and toolbox" from the Play Store. It might help.

Did you install the update?

i am on the new update and the GPS inaccuracy happened for me in a LTE area. how many of you with this problem are in a LTE area when this happens?

maybe in that time, your device only accees the AGPS to get your location.and hold on when phone find the gps satellite you will get the most nearst location

I'm in an LTE area and my gps has been flawless to within 5 meters, before and after the update.

Here in NYC my GPS is perfect. It locks on about a second after I open Maps or Navigation.

GPS not locking

GPS no longer locks after flashing black ice. Should I be using the old original GPS fix? BTW...best ROM ever...Krylon/Team Whiskey rocks!!!

I'm actually having this problem as well with bionix frost. Everything else works flawlessly.
Sent from my SGH-T959V using XDA Premium App
I think I'm gonna apply the old fix later and it should work ok. I'll post the result regardless.
Sent from my SGH-T959V using XDA Premium App
I applied the sgstools fix, enabled the gps, but nav still would not lock on. So I opened maps, let it find my location and settle in until it was accurate, the opened up navigation and it worked fine... No more "Searching for GPS"
Might work for you also...and it's an easy fix.

I see that other people in the black ice thread are having the same problem but I can't share your fix with them as I don't have enough posts for permission in the developer theads...would you share this with them? Thanks again

i searched for sgs tools on the market and it only came up with the capitavate sgs tools. is this the program which you guys are using?
That is correct
Sent from my Galaxy S 4G
Hmm. This fix worked for a few minutes, but when I restart the phone, no more gps lock/navigation. Weird. Thanks for the info.

i followed the instructions using launcher pro and set it to "auto" and it seemed to work. i still have to wait a while to get a lock sometimes, but thats tmobiles fault. they suck in my area. hope this helps anyone else having this problem.
EDIT: It only works once. does anyone else have the locking problem for bionix frost? i can try to reflash my phone and see if that fixes it.

Best GPS?

Going to Vegas tomorrow and needing the best rom with the most reliable GPS any ideas on what worked best for them?

Google maps always works best for me in big cities.

For me its been stock using Google navigation.
Sent from my LG-P999 using XDA Premium App
I'm fairly certain the application used is irrelevant, the GPS gets the same result no matter what. ROM might influence it, but I've never noticed a difference.
I vote for Google Maps in any case.

GPS question

What's the best way to get GPS to work properly? It takes me anywhere from 4-6 mins for a lock. And while it's trying to lock on, the battery just drains. I use GPS tool to get a lock and trying to cold start it. What's everyone's solution to this?
Sent from my LG-P999 using xda app-developers app
For me 100% reliable: use GPS status to download AGPS data>reboot (must be outside obviously)>use GPS status to get lock>use location app of choice.
Also, on March Baseband, I get GPS locks on the bus moving down the street. If need a functional GPS you really need to be on the newer baseband.

I on V21Y. That worked pefectly. Thanks!
Sent from my LG-P999 using xda app-developers app
NP. Yea, it's stupid, no reason I can see for the need to reboot, but GPS lock seems dependent on it.

Network mode problems after cm10 and sim switch

I'm using an infuse 4g with JB 4.2.1 cm ROM. I unlocked my phone and put in a T-Mobile prepaid sim.
I'm supposed to have 4g consistently but I'm getting 2g(edge), 3g(umts) and on very rare occasions I get 3g(HSDPA)... Its approximately 70%-%20-%10, respectively. And these changes are all happening in the same household. No tower switching.
I only have the option to switch on 2g only in my network mode settings on cm10... APN settings are correct and all T-Mobile can say is that I won't get 4g if the tower doesn't support it..
Are there any possible solutions to obtain 4g at all?
If so, how do I keep it on all the time?
Do I need to install a new modem?
If so, which?
Any comments and/or answers would be greatly appreciated.
Thank you.

Using Uckl2 at the moment. FYI.
Also, I know the modem is for WiFi but does it affect carrier data? If not what can I change to affect my data connection?
Sent from my SGH-I997 using xda app-developers app
I always thought the opposite. I thought modems were only for mobile data. But does switching modems help?
Sent from my SGH-I997 using xda app-developers app
Could increase or decrease your signal and rate at which data is downloaded and uploaded depending on your modem of choice. Battery life is also affected minimally (usually).
Sent from my SGH-I997 using xda app-developers app
Hmm, didn't know that... Well thanks for the lesson but have you tried switching modems?
Sent from my SGH-I997 using xda app-developers app
I switched through a couple and uckl2 seems pretty stable but no change on carrier network service.. I want to put on kl3 but I can't find the download.. Not too many options for my phone though.. That I know of.
Sent from my SGH-I997 using xda app-developers app
It might just be your location.
Sent from my SGH-I997 using xda app-developers app
Since I changed to cm10 and switched to T-Mobile sim I have yet to have 4g. Tried where I'm at now and up to 70 miles from here... Very weird. I can't tell if its T-Mobile or the ROM.
Sent from my SGH-I997 using xda app-developers app
Have you had it before on the same phone? Have you tried using another 4g phone?
Sent from my SGH-I997 using xda app-developers app
Yeah I had 4g on it before, on att and on metro. Both while using stock Froyo rom and GB aeon rom.
Sent from my SGH-I997 using xda app-developers app
Weird, it sounds like its the network then
Sent from my SGH-I997 using xda app-developers app
Yeah that's what I'm thinking but when I called T-Mobile, they said that they cannot diagnose a non-tmobile phone. The only info that they can give me is that they assume its my location and possibly the modem but they cannot guarantee switching modems will work. Doubt they hack phones though, Lol
Sent from my SGH-I997 using xda app-developers app
from my recollection..not from experience:
T-mobile or networks other than AT&T will only give you: edge or 3g.
No 4g or hpsa+
to get better than 3g, you need to be on AT&T
When the phone is on "H" I ran a speed test and its pushing 5 to 7 mb download speed. Is that close to 4g?
Any advice on how to stabilize the network?

yup.. 2-6mps for most.
if you are in an urban area and close to a tower, some are reporting 8+
look back in the old threads..i recalled these discussed toward the beginning of device release..jun jul aug 2011 era
Appreciate it, thanks!

Once you have a lock do you have any issues with stability, losing it etc?
