Please help my resolve my Searching For GPS issue - Epic 4G Q&A, Help & Troubleshooting

Hello, I am running an Epic 4G rooted with FC09 Pre rooted rom. (CWM / Odin)
I just rooted a couple of weeks ago as I was thinking it might fix up my GPS issue, but other than the phone being a bit faster and me being able to get rid of some junk... the GPS issue is the same.
Using Google Navigation, unless I'm within a couple of minutes of my destination will go into a "Searching for GPS" mode... then eventually lock up.
The TeleNav software works flawlessly, but I don't get the Satelite views like Navigation which are real handy around here with all the hidden signage and such. I don't recall the Telenav software ever loosing Satellite other than the typical brief hesitation of the tracking icon, and then it catches up.
So far using Titanium I cleared the cache and uninstalled Google Maps. Verified both the Maps and Nav icons were gone from menus where they exited, space recovered etc.. Restarted phone. Installed Google Maps. I did this before it was rooted as well, using the Store as normal.
I installed the GPS Test software. I noticed in only slightly less than optimal conditions like indoors, but next to a south facing window, it will show good signal on 11, 12 or more satellites and show NONE in use. Not sure if this is useful or not because as I stated... Telenav works all the time and seems to even track better than Google Navigation.
I have seen info on a GPS Fix but wasn't sure if it will work on FC09 pre-rooted rom.
Frankly there is a TON of discussion about this phone and the GPS, but I haven't seen any concerning FC09 and also noting that Telenav has no issues.
Any assistance would be greatly appreciated. I love this phone. I'm not sure I understand the advantages of rooting yet, but other than this GPS annoyance, I love this phone.
Thanks in advance.

Did you try clearing and resetting AGPS in GPS Test?
Sent from my SPH-D700 using xda premium

Umm... no I didn't. Well not until now. Didn't know I had that option but found it and did it now. Is this something that will need to be done any time I get the "Searching for GPS" or is this something that fixes the problem altogether?
Thanks

Ok, well good news/bad news. I had the opportunity to test as I just went to the bank, less than a mile away. As noted above I did the clear and update.. Navigation acquired and routed faster than I ever remember it doing it. I actually started IN my house, put the phone in my pocket, took it out of my pocket and put it on the dash in the car. As soon as I started moving in the car it was tracking perfectly.... for about 1/4 mile. While I was waiting at a light, yes stopped... I saw the "Searching for GPS" come on.
For giggles I did a clear and update of AGPS again. At this point I was already at my destination so I entered my home address. Again it found it immediately and routed immediately and I didn't even get out of the bank parking lot before I got the Searching for GPS. I decided to just observe and noted that it was sortof tracking me, but I think that was strictly AGPS and Wifi vs Satellite. When I got home, GPS Test showed 9 Satellites NONE in use. So standing in my driveway I did the clear and update of the AGPS again. It immediately went from none in use to 3 in use.
Again, I have had this issue long enough to know that Telenav would have worked fine. In fact I had a 45 minute ride just the other day at night, that started in downtown Bellingham, WA (City streets) where I had to turn around a go back for something I forgot and received two phone calls. Telenav Never missed a beat. So I'm thinking it's the Google Maps software more than the phone, but at the same time... Google Maps works just fine on my wife's Epic 4G. Her's is not rooted. It occasionally looses sat reception, but she either just exits and reenters the program or turns the GPS off and ON and she's back in business.

Maybe I wasn't clear enough in my original post. I uninstalled and reinstalled several times before rooting and at least twice since rooting. I used the term reinstalled, sorry for the confusion.
This also included clearing all the maps as well.
I have read about some sort of gpsfix app.. but not clear if it is for my version. Is that an option?
I'm open to all options at this point.

If Telenav works flawlessly then there is nothing wrong with your GPS.

Maybe I'm making an assumption about how to delete all maps and unistall / reinstall the Google Maps program.
What I do is go into the program and clear all map tiles, then exit, go to Play, and uninstall. I also did the uninstall at another time via titanium by clearing cache and then uninstall.

Ok, so something is definitely up with MAPS. This time I cleared the maps, removed it again, insured the apk was gone. Restarted phone, ran gps test and cleared the AGPS and reset etc.. THEN I installed the latest version of Google Maps.
Same thing... I get a little down the street and I stopped to drop off a package at the postoffice and it's "Searching For GPS". GPS Test shows only a couple sats in use... but I bring up Telenav. I ride around the area with a destination programmed nearby, but I keep making turns to try and trip it up.... it stays with me and just keeps re-routing as needed.
If Maps tracked as well as Telanav I'd be a happy camper. While the telenav app is good for the actual directions, there is no satalite view without paying for it (google it's free) and entering destinations is a pain in the butt and not as accurate/quick as google.
Is there some conflict between Google Maps and the Epic 4G ? This is just silly.

Google Navigation Locking Up

I am running Legendary Rom RC2 and Samurai kernel.
The problem i am having is with google maps/navigation. It has been randomly locking up lately. Seems to do it randomly. Sometimes it will navigate fine for 20 or 30 minutes and then i look at it and its locked up (screen still shows map but none of the buttons works- i have to pull battery to restart). Sometimes it does this a minute or two into navigation.
I've waited to post this hoping i could figure out what was happening. I've tred waiting to see if its just a temporary lockup but its not. I am also running juicedefender so i turned that off but it still locks up. I have uninstalled and reinstalled maps and it still happens. I havent been able to notice a pattern of it occurring when there is a signal loss or certain areas or anything like that.
Anyone else having a similar issue or have any suggestions of things to try to fix it? Thanks!
What version of Samurai? There were issues with 2.08. Try uninstalling Maps and redownload from the Market.

Still no luck getting this to work. Tried uninstalling/reinstalling multiple times. Also tried a new kernel (Nubernal now instead of Samurai). Any other suggestions?
How about clearing AGPS data with GPS Test or GPS status and download new AGPS data?

You can always ODIN back to stock if all else fails. I hate google navigation. Google has been sucking it up lately with their new maps release. I get lag GALORE, and have also had some FC's with navigation.

I agree. That is why I use Telenav 7.1. Clear voice and hasn't locked up at all on EI22.

I've noticed this same thing now and again, and I'm chalking it up to the Google Maps updates. I don't think it's anything to do with GB or any of the ROMs, because I'm pretty sure it didn't happen before Google Maps updated their version with the inside maps, which I think was 6.0, but I might be off on the version.
I have a hard time going with TeleNav becaues Google has so many nice features like sharing via email/text the exact location, but I seem to be having a harder time with it locking up (like the OP said, maps still shows) and missing a turn!
How can I get the latest version of TeleNav?
Google just needs to re-release their first version of MAPS. I have virtually zero lag when I first bought my phone, the maps that came installed worked perfect. now its barely useable.
I have tried using Telenav but its just not my thing. I never use GPS navigation anyways. I only use google places. Maybe two times out of the year I will actually use GPS nav.

I found it in the market (for some reason, I thought if I went that way I would have to pay for it) which was redirected from the telenav website. For what it's worth, I did end up with 7.1.0.7101357 according to titanium backup.
not a fan of telenav but since it sounds like its not a problem with just my phone i might have to get use to it. hopefully google fixes this soon.
so its not a problem with google maps/navigation, at least in my case. telenav does the exact same thing. i tried it out a few times today and it was also very laggy and then eventually it completely locked up. i used gps status to reset the gps but that didnt help. any other suggestions?

Have you flashed the GPS fix or a ROM with it included so you start out with like 8 out of 9 satellites?

GPS not working in Google Maps

*Update* January 7, 2012:
After reinstalling the Facebook for android app, I noticed that the problem with the GPS came back with google maps. After a few reboots, I've found that the Facebook app somehow messes with the GPS so that Google maps cannot use it. This is solved either by uninstalling, or never opening the Facebook app, as well as a reboot after every time the Facebook app is used.
Hopefully this will get rid of some headaches people are having with their GPS problems.
December 9, 2011:
Since the new update with Google maps, my phone hasn't been able to keep a GPS signal. When I open up Google maps, the GPS icon starts blinking, and then connects and everything works fine for about 2-3 seconds. After that the icon dissapears, and it goes to what I'm assuming is the triangulation of the cell phone towers, which is much less accurate. Anybody else having this problem? I'm running CM7.1 and everything was working fine until I updated the Google maps app itself. Thanks in advance.

+1.. same issue:
I've encountered a problem with my GPS while running AOSP Roms. (In my case MIUI) The problem is that after a while of using the GPS, I'll wake the phone up and the GPS will get my location, but then stop working/updating location. Sense ROMs seem to work fine with the GPS.
I've tried flashing the stock Sense ROM, and doing the ##GPSCLRX# trick without success. The method simply doesn't seem to work, or have any reaction whatsoever. I can't get the text box to open where you enter the MSL. Has anyone had any success doing this method? If so, which ROM did you use? Was there any special mojo you had to do?
I've also in desperation tried installing various EVO GPS drivers, with no effect.
Anyone know of any fixes?
hmm haven't tried it yet. I just switched back to sky raider (omfg froyo!) from CM7.1 because of the constant force closes and freezes with CM. I'm downloading Inc Deck right now. Will let you know how it works on that, later tonight.
But can't you just uninstall the new updated Maps, and revert to an older version?
I've actually tried different GPS mapping applications, GPS testing apps, and the problem remains. :-/
Well I just installed Inc Deck (AOSP) and Navigation/Maps (6.01) seems to work fine. It locked on nearly instantly, and I drove around several blockes (2-3 minutes) and had no issues with losing GPS lock. Although I was having a problem of zooming into Maps (wouldn't get closer than 2000 feet on scale bar, the scale bar is an addtional lab add-on). Although it seems to be zooming in completely now...I will try to remember to keep testing and give feedback.
Maybe try clearing caches?
update: I've used the newest Google Navigation (6.01) probably 4-5 times in the last 24 hours, I have not lost GPS signal once. Total time running Navigation is over an hour. This is on AOSP Inc-Deck 1.3 stable and latest Incredikernel. So it must not be all AOSP ROMs that are affected.
I've reverted back to the previous version of Google Maps for now. After trying all of the above mentioned tips, nothing seemed to work. Thanks for aall of the help though

I "fixed" this by installing LBE Privacy Guard and blocking Facebook's GPS access. The app force closes when using the CM7 permissions management to revoke FB's GPS permissions, but works fine with LBE. Now, I can leave the GPS enabled, and use google maps & facebook without the GPS getting hung up.
Awesome, I'll do just that. Thanks for the input

You could try changing your gps server. Go to /etc/gps.conf and open it with a text editor. Make it look like this:
Code:
NTP_SERVER=0.us.pool.ntp.org XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
SUPL_HOST=supl.google.com SUPL_PORT=7276
The first line NTP_SERVER should be all you need to change, the 0 can also be a 1, 2, or 3. Also add supl info if not there already.

GPS is suddenly EXCELLENT!

My GPS has all of sudden started working FLAWLESSLY. I have changed nothing on my phone in the last couple of weeks. While sitting sitting in my living room today, I decided to turned on my GPS as I do often in the same spot. The only difference, instead of picking up zero satellites, I picked up at least 5 and Google maps is working great.
Has anyone else noticed sudden improved GPS?? I hope this lasts...

I can't offer much historical performance, as I just got my Epic yesterday, but I was able to quickly get a gps lock at my house last night, and while driving today. I leave GPS on all the time.
I'm pretty sure this is due to me wearing my tin foil hat.
You're welcome.
Maybe this is a dumb question, but how do you check?

You can do this a few ways.
1) Make sure GPS is on, and go into Google Maps. See if it finds your location when you are indoors.
2) Make sure GPS is on, and download GPS test from the market. It will tell you how many satellites you are connecting to, and how strong the lock is. It also tells the accuracy of your location, in meters.
http://www.spaceweather.com/
GPS Status & Toolbox is another great free app from the market. Tells you how fast the GPS locks in seconds, number of satellites, longitude, latitude, compass bearing, etc. It will let you clear and download A-GPS data as well which one should do regularly.

perhaps a neighbor cut down a tree which has been blocking the gps signal to your phone. haha.
Awesome!!!!
Mine says I'm at home too... Even though I'm currently at work about 10 miles away.
The GPS on this phone stinks!!!! But everything else is flawless.
I noticed a huge improvement a week or two before el29 went officially OTA. I was already running the leaked el29 modem/kernel mind you. Maybe Sammy/sprint changed something to play nice with the new release *shrugs*. Before this it would take awhile for GPS Status to lock on sats, now it usually locks in under a minute!

The massive solar storm probably had a lot to do with it.
Not sure how the epic touch works, but I believe most phones do not use true GPS. The GPS module is usually assisted by the cell radio. Sprint probably improved cell coverage in your area.

Yes the phones do use the towers as a "rough location" while searching for satellites.
and if we have no tower signal.. we get no GPS
GPS should work.. cell signal or not. boooo A-GPS.

You should be able to uncheck the option to use the cell network to assist with GPS lock. I think it's under Settings, Location, or Security. It will then only use the GPS antenna to determine your location. It will probably take about a minute to get a lock, however.
I haven't tested this out, so it's all theory, but on paper, the theory should be sound.
My old Samsung phone had major gps issues but once I got a good lock and started using gps regularly it worked fine till I started trying out different roms. This phone gps seems to be working fine so far
I've never had a problem with GPS, but I live in an area with good cell coverage

Offline GPS.. completely reliant on cellular or could I not hit the satellites in JA?

I went to Jamaica last week and downloaded an offline cache of most of the island for Google Maps. I figured if the cell phone has GPS I could use it.. I guess I didn't realize how dependent the GPS was on cell signal because it never found a location. I still had airplane mode enabled because I was paranoid about incurring accidental roaming charges, but I just tried it here and it doesn't work with airplane mode enabled either.. makes sense I guess. I disabled airplane mode while I was there and it still didn't work. I had the Google Maps cached data so I just navigated by looking at street signs. Just thought the GPS should work. Did I assume incorrectly or maybe do something wrong?

When I was in a Jet of all places I opened up GPS Speedometer to see how fast the Jet was going at 30,000 feet. I never got a signal but as soon as we got closer to ground and picked up AT&T for a few seconds at a time the gps started to work. So to test it again before I took off the second time, I opened up GPS Speedometer and had it lock onto my location. After take off and at 50,000 feet it was accurate the entire way. So my guess is it has to have a data connection temporarily or something.
i tried this when i was in a similar situation with BRUTE google maps (same style of downloaded cache of maps) and it was very inconsistent and buggy. in the end, i downloaded a gps app (copilot) and it worked perfectly the entire time with my phone in airplane mode.
hope that helps

This is the best solution. CoPilot is the best navigation app and doens't rely at all on cellular networks or Data
Perfect! I should have done more research before leaving
Just got back from Mexico and had a similar experience. I precached my location assuming I can use navigate offline over there, I was mistaken. First, I turned off data cause roaming data costs an arm/leg so I had no data, just voice roaming. With my GPS on, I literally had to stick my phone out the window so it could lock on some satellites. When it finally did, I was able to see my location on gmaps. When I tried to navigate, that's when the app complained about needing data. All I could do was just see where I was, unable to navigate. I think I'll have to find another solution for offline navigation.

[Q] GPS reset? My GPS is loosing signal alot now

My GPS looses signal alot of the time anymores.
It started happening a few months ago.
Is there a GPS reset somewhere in the settings?
My note 4 is on DPD1.
And it does not update itself anymore, nor can I update it manually.
Since I enabled the wifi hotspot, I believe.
Can any-1 suggest a GPS perk-up so it will act as before?
Thanks alot.

I noticed that this started when I upgraded to the latest version of Google Maps. I went into the app settings and uninstall the latest version. And it reverted back to the original version on the original ROM. The GPS is working great again. But now I don't get to use the offline maps as my version does not have that like the latest version did.
I use Waze and this happens, so I don't see how this is related to Maps.
i just replied to a thread about this. my phone just absolutely cannot lock onto or find gps sats now.
dunno if its the custom rom, google maps, the radio being corrupt, kernel, or whatever.. its bugging me becuase im always out using my maps.
I had no GPS in till I uninstalled Magisk.

If you'll goto Google Play and view Google Maps app description, you'll see some linked suggestions to improve location.
It's the first time I've seen the suggestion and directions to calibrate the compass. Mine had been wide and possibly pointing wrong direction but the calibration actually seems to work as described in the animation.

Long trip last Tuesday with Google Maps beta was without issue. I did notice the wide compass indication when on data; I tried the calibration again in my driveway but it stayed wide. My GPS usually is spotty near home. Navigated fine without GPS lost warnings.
Just as I started navigating, app said it would download maps along my route to improve navigation. I took the phone back in the house to sync that data first. Not a chance Sprint data would be any help here. Minor inconvenience; I had searched the location a day prior to check the estimated time of arrival but didn't get that prompt to download maps.
The beta app has updated twice since then. I'll test again on a return trip. Get the feeling Maps has always been beta.
I'm on UN7 custom ROM. I followed the prerequisites of that ROM on install; PJ1 stock tar and verifications included GPS lock prior to ROM flash (made a TWRP backup). When the modset for that ROM was released, I eventually started over with my PJ1 stock tar TWRP backup, flashed UN7 ROM and then flashed modset.

The problem is the contacts on your phones mobo have become compressed and or oxidized. . You need to dissasemble the phone. Remove all screws and seperate the phone from the screen to get to the back of the mobo...
IMPORTANT... When you pry the case from the screen you need a heat source hair dryer or heat gun to soften the adhesive holding the frame to the screen. .. You will need a plastic tool or guitar pick to pry it apart.... Again it is important you use a heat source to soften the adhesive or you will break the digitizer and or screen. .. Once you have the case separated from the screen and motherboard the contacts will be on the upper right of the motherboard. .. Gently pry them up so they make better contact to the antenna in the case...

took back cover off, and used a needle to pry up all the metal contacts on the back to touch the cover antenna sticker.
gps hasnt dropped yet, been using all week in the city. i'll see how it goes on the interstate out of town.
