GPS Fix for Epic 4G Touch?

http://forum.xda-developers.com/showthread.php?t=1321049
Could we use this GPS fix for our phone? It has really good reviews but I just wanna be careful about flashing stuff :/
Can any knowledgeable developer look into this file and see if it is compatible with our phones?
GPS issue is very prevalent among Epic 4G Touch users and I hope this file could fix our problem.
Thanks!

I hope so.. GPS is crap

Well the fix seems to be for all Gingerbread phones, so it should work, right? Can any developers shed some light into this?

i gave it a try, but it doesn't seem to make any difference.

Thanks dunebuggy. i wish a dev can come across and open the file and compare with our values..
Its threads full of people getting better lock ons!

Has anyone else tried it? I'm pretty desperate as I've tried everything.

I just picked up my replacement the gps works perfect. That is the only real fix. Some work some don't

Doubt it will do much.. uses the s5pc110 hw library... Can't open up the vendor daemon and compare it tho at this computer.

I honestly didnt even realise that the epic touch had a GPS problem going on. Mine always locks in less than 10 seconds and says accurate within 6-2m. It usually says 2m but on occasion 4 or 6. what are the symtoms of bad gps? I know it will either not lock on quickly or it wont the correct location. But what tecknically is a slow GPS lock on time to within 6m? Like 30 seconds to a minute? And what is considered not being accurate? Like within 15-30m? Im oretty curious. Maybe my 5-10 second lock on time and 2-6m accuracy is considered a GPS malfunction? I just never use it so i cant really know what is considered good or bad. I know mine uodated my position every half second to tge longest taking a full second when i used the car navigation app after putting in my desired address. Please e, plain

GPS never locks on indoors, and it takes at least a minute to lock on outdoors. Also my gps never locks on in a moving car.

GPS should lock outside in a few seconds, it should lock or almost lock indoors within a minute, and it should definitely follow you while driving so that google maps navigation works.
if it is not doing that, take your phone to sprint and get a new one. my GPS was fine when i first got the phone, then a month later it started doing what people complain about, slow lock or no lock, and not following when moving. i complained to sprint twice, paid $35 and got a new phone and now GPS works fine.
the gps tool kit, flashing drivers from the wrong phone, and editing files never gave me a permanent fix. go exchange your phone.

^This except I didnt have to pay anything (tep)

I've had a lot better results by using GPS Status. Before I use anything that requires GPS, I let GPS Status lock on, and I have a lot better results.

Speculative on indoors.... Multiple factors to account for to get an accurate and true lock...

Well I've flashed it and it actually works in my experience. I've let me phone sleep for hours and it has been an improvement over previous fixes.
Still intermittent gps though.
How is everyone going about getting a replacement E4GT? I bought mine on launch day if that changes anything.
Is this something I can do over chat?

For those of you with GPS "problems"...try the following fix next time you have issues. Not sure what causes it, but anytime my GPS starts to suck I do the following and it fixes it instantly.
Menu->Settings>Applications>Manage Apps>
Click on the "All" tab
Click on "Maps" -> Clear cache
Back to list of programs
Click on "Network Location" -> Clear cache
Exit back to home and all should work much fast....at least it does for me
Let me know if this works for you guys...

I am not sure if it is a hardware problem or software but I rooted my phone within the first 24 hours of owning it. I run Calkulins ROM V2.6 [EL13 Kernel] and EL13 modem.
I have no problem locking indoor/outdoor fairly quickly. I did notice the indoor accuracy is slightly less accurate that the Evo 4g I had, but when it comes to locking time, and outdoor accuracy or moving "target" accuracy/lock I have ZERO complaints as of now **knock on wood**

[Q] GPS wandering, any one found a software fix?

I've read just about every post in this forum that even mentions GPS trying to find a solution, but no luck, so I'm asking outright in case I missed something or someone has the answer and hasn't contributed it yet.
My One X has horrible GPS.
I'm not talking about how long it takes to find satellites, it does that quickly enough. What I'm talking about is using an app like My Tracks, Endomondo, Run Keeper, etc to record a track. If I sit the phone perfectly still and let one run, the position and track wander all over the map like a drunken sailor looking for a good time. If I actually move in a straight line, the position shows me blocks away from where I really am. If I try to use a navigation app, the directions are meaningless because the phone thinks I'm as much as 1/2 mile away from my actual position. (I should post a video of that, it's hilarious how bad the directions are.)
Please don't respond if the only problem you've had with GPS is that it took too long to find satellites and downloading someone's aGPS fix app or tweak solved your problem. I've tried all that, multiple times.
I suspect it's just bad hardware, maybe bad antenna connection or something similar, and I'm going to need to replace the phone, but before i go through the hassle of trying to get HTC to replace this dev unlocked phone, I want to make sure there's not a software fix possible. I'm past Expansys' 14 day return window, so HTC is my only option, or possibly my American Express warranty service.
Any thoughts?
The pic is a screen capture of the phone sitting in my parked car in an uncovered parking lot for about 10 minutes. Note how much it wanders around.

Well, no replies, so I guess that means a big NO to any one actually finding a software fix to this particular problem.
For what it's worth, I installed CM9 in the phone and the GPS is still unable to hold an accurate location, so I'm sure it's a hardware issue at this point.
That's a real pisser, since they told me the turn around time on fixing my phone will be 3-4 weeks at the HTC Warranty Repair center in Houston, TX.

I hate to say it, but it must be your unit.
I use GPS navigation very frequently (SoCal, USA) - and coming from a flawless GPS on SGSII, I have to say that HOX GPS is even better. It's more precise - it can even correctly show which side of the road I'm on. Also, driving past intersections is spot-on, which shows how on-the-spot it is.
Did you install any cases, or keep it somewhere where antenna signal may get blocked?

I didn't want to believe it, but I concur it's got to be a hardware issue. No case in it, nothing blocking the antenna. I have same issues even laying it on a patio table out in the open.
I'm also in SoCal...San Fernando valley and the west side of Los Angeles. The one time I tried to use the GPS for navigation it was like getting affections from the three stooges.

Mine does exactly the same. Calibrating the compass an turning wifi off while using gps solves it for me. Gsp is spot on whe wifi turned off... turn it on while navigating and it wonders off road....

I had the same problem, I downloaded GPS Test Plus from the Market, went into settings, selected Clear AGPS and then selected Update AGPS - seems to have been tons better since I did that.
Found this via an Internet search so Kudos to those who discovered it although I apologise I can't remember where I found it!

Yop this I remember even from the iPhone. Accuracy +50m when Wifi or Mobile network assisting with the position. Without max 5 . and not much wandering
Just turn it off in the location. As the breugiek above me suggested.

Thanks for the responses.
As stated in the original post, this is not an aGPS issue. I've tried many aGPS type fixes..Faster fix app, crypted fix and a few others.
I didn't mention it, but I've already tried turning of wifi; it makes no difference.
I suspect bad hardware, specifically something wrong with the antenna.
Annoys me no end to be HOX-less for a month. I've only owned the damn thing for 4 weeks.

Kinda meant the settings > location > Googles location service = un-check. But I guess you already tried that one :/ (but mentioning it just in case)

I'd posted a wandering track from a parked vehicle in the OP, but for those interested, here's a two-minute video of the HTC One X GPS in action while trying to use it for Navigation with the Google Navigation app.

Mine is the same but only when I stop the car at lights etc. Sat nav shows me going rallying across field and drowning in the sea when near the coast, sorts itself out when on the move again tho.

I may have found a fix (it works for me so far anyway) - see my post here...

Thanks for the suggestion, I've already seen your post in the other GPS is messed up thread. I tried it and it doesn't fix my phone. Clearly bad hardware.
Cheers!

GPS now working fairly well on this phone. It's not perfect, and requires WiFi off, but other than some initial wandering at startup I'm getting accurate tracks on it.
The fix was to install ARHD 7.0. No idea what changed from earlier versions but it works well enough to put up with until I can get a shorter repair time quote from the warranty center.

Look for my thread regarding this problem. fixed it finally!

Thanks! That did the trick...much appreciated!

Hmmm, I still can't get it to work. I managed to get a searching icon for a bit and it disappeared again. I think that plus the failing update thing == me taking it back in the morning and getting a newer one from a different Best Buy. I tried clearing framework services and reverting the maps app multiple times and no go. Even standing out in the middle of the street at 3am trying to get it to lock.

Mine locked right on for me

I'm wondering if it has something to do with that final 50MB update that won't install.

I had the update fail, and my GPS was dead, too. Swapped it at Best Buy. New one had no update issues and GPS works great!

Can you do some extensive testing with the gps in the new exchanged one??? because I got gps working good on my tablet but after using it for awhile it like turns itself off, shows a searching for gps flashing icon at top left of screen and cannot lock on to satellites no more!

Hoping that will be my case too, just got back with a shiny new replacement, from a different store this time that just got their truck in and unloaded late last night. So hopefully I'm avoid the "bad best buy batch" lol.

My GPS works flawlessly. Connected to satellites almost immediately.

Looks like I'm good to go, replacement has no screen issues (dust or pixels) and the update installed perfectly, GPS locked in about 15 seconds, mostly waiting for me to step out of the house I'm guessing.

My gps suddenly failed to lock on to any satellites when playing ingress, reboot fixed it

I've never had a device which locked on as fast as this Nexus 7. Its beautiful. Make sure the top of the device isn't being smothered by your hand because that degrades the signal received significantly.

Knock on Wood, I think I got the gps problems nipped in the butt!
I had to reset the tablet from system settings after having both updates installed, when setting up tablet (initial boot) enable all location stuff except for the new android 4.3 wifi location while off option.. Also make sure to disable backup and restore options while doing the initial install.
Now so far GPS has been working steadily ever since first initial boot, no need to reset and power up again and after trying it for an hour all gps apps back and forth its still finding signal sometimes instant sometimes 20 seconds or so but no issues like before this time...
Working like it should now! I guess a hard reset after all updates was needed to reconfigure things!

As long I only use Google Maps, the GPS locks consistently.
If I use other GPS apps (like GPS Status, Gas Buddy, etc.) then eventually the GPS gets into a state where it won't lock, ie the GPS in the status bar just blinks forever.
Reboot has fixed this every time.
When the JSS15J first installed, the GPS also wouldn't lock. I had to turn on WiFi/Mobile assistance for it to lock the first time. After that first lock, I could turn off WiFi/Mobile assistance and it would still lock on its own.

i can't have any issue

Can't seem to get a GPS lock on any 5.1 rom

Ever since the transition from kk to lp, I've been struck on my GPS never locking on properly. Even tho the rom says it works, it hasn't for me. What have any of my other brothers and sisters with a note 2 done to fix this problem?

People read this and can't seem to respond. Hmmmm
Great community

Same problem here... GPS dead even after going back to 4.4. Did you fix this?

It actually fixed itself for me. I have no idea how this happened but after ca. 2 weeks without GPS it started working.
It's not working reliably, though: I used to be able to get a fix every time i turned on my Note, now sometimes I don't get fix for hours. On other times, the fix happens immediately.

For me, i find a this way helps, not sure why it suddenly become like that :
- reboot phone
- after rebooted, turn off location first
-run "gps test" app with location off
-turn on location and let gps test do is thing to get 3d fix
-once you can get 3d fix on location, exit the apps and you can start using Google map, Waze or any by other gps apps
-as long as you dun turn off location after this, the GPS lock should work
-repeat step 1 if gps lock is not working again
Hope this helps, it's not a permanent fix... hope someone can come up with a permanent one.

GPS Problems Even on Stock

Love my Note 4 but lately I have had nothing but problems with this damn thing. GPS NEVER stays locked for me use navigation or even check the weather if I changed cities. Saw the fix on where you take the back of the phone off and adjust the GPS contacts, long story short the LCD screen broke on me. I see nothing but problems people have on this phone about the GPS and Samsung will not hold there end. Anyone else have the same issue with there GPS?
Sending phone out to get repaired tomorrow.

i was on cm13 for a few days and i had horrible gps on google maps. when i returned to stock, gps was fine again. if ur having gps problem even on stock it may be a hardware issue.

If you have time, file an Android bug report: h t t p s://source.android.com/source/report-bugs.html
I have the same problem with stock ROM. I have also had the problem on 3 other completely different Android phones from different manufacturers - also running either with or without the stock ROM - mostly on Lollipop. This is probably not a hardware issue as another member has suggested, but a bug. I seriously doubt that the 4 different phones I've experienced this with all have hardware faults. If you file on that website, I'll join you. You are not alone.

Sounds like you solved the problem with a new phone. If the problem ever arises with the new phone you may be interested in my post in http://forum.xda-developers.com/note-4/general/gps-close-to-unusable-t2948602/post67864418 (see post #339). I was able to fix my phone by partially disassembling it and removing corrosion on various contacts.
