Unhappy PLEASE think before you just act and do what Sprint tells you to do.

So, you can quote this Sprint employee as saying "There's no known issue with the Epic 4G GPS." Please use that in the future.

That said, please make sure your settings are correct:
To use aGPS (assisted GPS) you need to make sure you enable "Use Wireless Networks" and "Use GPS Satellites" in the Locations & Security menu in Settings.

Check to make sure you have enabled "Use My Location" under the Privacy menu in Settings.

If you still have problems please send me a PM. Thanks for being a Sprint customer and Epic owner!

I urge people to please understand the implications of what this Sprint Employee is saying. He is asking you to turn on "use wireless locations." By doing this you will never know if your GPS works.

Per wikipedia, "GPS was created and realized by the U.S. Department of Defense (DOD) and was originally run with 24 satellites. It was established in 1973..." Simply put, GPS SHOULD WORK WITH SATELLITES, using wireless networks is a cruch, you will be using less accurate wireless networks.

People, you don't have to be a brain surgeon to understand. It is simple, you paid 249.99 for your phone, do you want to know if your GPS works by using satellites, yes or no? If the answer is yes, then turn off assistence from cell phone towers, and make sure that you paid 249.99 for a phone that should be able to detect and use satellites with accuracy. THIS IS GPS, use wireless network assistence IS NOT.

If the answer to the question is NO, then by all means, turn ON assistence from the wireless network, mask a possible major GPS flaw and depend on cell phone towers, instead of what the US govt created GPS with, TO USE SATELLITES.

Here is a thread that shows how to properly test gps/satellite.

I got mine at a Sprint store at 8 am of release day and my GPS works great. Haven't had a single bit of trouble with it. Seems to always find me within a few yards and locks on fast.

FWIW, I've had zero problems with my gps.

Also, somewhat random, foursquare with my blackberry tour had me as about a whole block away from my house if I used it at home. My epic has my exact address.

this is great news, but is your "use wireless networks" on or off?

So as promised here is my "My Tracks" recording. I think it spells it out pretty clear for my device at least.

Gps Test At Shopping Center - Google Maps

It was more accurate than I thought lol

Well the problem was that "My Tracks" is set by default to record a little slower than you move, I suppose this way you can backtrack if you made a mistake and not be too far off your prefered path. You can set it to record much faster in the settings, I of course didn't realise this until after finishing this track. This is why my "Os" look more boxy/triangular.

Plus it's really hard to walk in circular path without a guide of some sort....

Basically this seems to be coming down to a problem of some phones work fine and others don't. The thing to find out is WHY some don't work. Is it faulty hardware, software, or something that the user is doing differently? The reason for the hostility in these threads is that not everyone is seeing the same results. Those who have a phone with bad GPS are assuming that all phones have bad GPS and those with good GPS are assuming that all phones have good GPS. The two assumptions can't coexist.


Personally mine seems to work fine. Have only done simple tests so far. Was way off when I was inside the store I worked at, stepped outside and within seconds it found my exact location. While driving home it seemed my location on the phone matched my location on the road almost exactly. While walking my dog the phone showed me infront of the right houses and even on the sidewalk. Inside my house it seems a little off (shows me as across the street). For me that works perfectly. For others that may not be enough.

That is with use wireless networks active.

http://androidforums.com/samsung-epic-4g/163692-testing-gps-satellite-usage-your-new-epic-right-way-have-use-wireless-networks-off-2.html
Having "use wireless towers" on doesn't preclude you from seeing if you're using satellites or not. In Android wireless towers only gives you a coarse location, and if you're using MS Based triangulation, it helps narrow down your location so that you can lock to a satellite faster. Once you lock on, you are no longer using the towers.

If you have a GPS lock (i.e. using satellites), the GPS symbol in Google Maps stops flashing. If you are depending on wireless tower (or other assisting) triangulation, the GPS symbol will continue flashing and you'll have a large (~1000m) blue radius on your map. If you're using Standalone mode, having wireless tower triangulation on or off makes no difference as to getting an actual lock (i.e. GPS symbol stops flashing). If you're using MS Based, it usually makes it quicker. Either way, testing with wireless towers on vs. off makes no difference if you are looking for confirmation that you are using satellites.

So in short, you are only using the towers when your position is shown on a map with the GPS symbol still flashing. If it is not flashing and you have a fine (no blue radius) position, you are using satellites. If you have wireless towers OFF then you won't get the coarse (blue radius) location and you will just see the symbol flashing. On = blue radius + flashing ==> no flashing when locked and using satellites; off = no blue radius + flashing ==> no flashing when locked and using satellites.

If you use an app like GPS test, you can directly see how many satellites you are in view and how many you are using, and having wireless towers on will not affect these results (except if you are using MS Based, in which case it might show more visible in a shorter period of time -- but it won't affect the "in use" stat)

I bought two Epics @ 10:00 AM yesterday from Best Buy. Didn't pre-order either. With use wireless networks off and the "My Location" thing checked (I wonder what that has to do with it), both my units worked well with Nav and Maps. Spot on accuracy. I also ran the GPS Test on both phones. One phone locked into 10 sats and the other 7. The one that locked to the 10 supposedly was accurate within 90 ft. or so.

After reading through this thread, it appears there are more successes than fails but I could be wrong. Maybe someone could do a count and that would give us some percentages to work with. Just a thought and also wanted to add my experience with the two phones. I think this phone kicks ass and just can't wait till they roll out Froyo. Imagine what that will do.

I got my Epic yesterday and the GPS on Sprint Nav works beautifully. It tracked me down all the side streets and the freeway. I'm very happy with the Epic so far, and I'm ecstatic about how well the GPS works on mine. Sorry that others are experiencing problems.

My Epic's GPS works great with the "use my location" setting disabled. I just got my Epic yesterday, but every drive I've made since then I've used the GPS and it has performed flawlessly. Earlier today, I tested it using the GPS apps and I couldn't believe how quickly it acquired and locked onto the birds. It acquires and fixes way way faster than my dedicated Garmin hand-held unit ever did. Today it has been extremely cloudy with rain showers all day and it still acquired 13 birds in a matter of seconds when I walked out onto my back deck earlier today.

I do think there is something buggy with the "accuracy" that is reported. Regardless of how many birds it locks onto, the Epic always reports 98.4ft accuracy and the GPS apps report 30M. All the time, every time, so I have a hard time believing the "accuracy" figures are accurate. Even with 98' reported accuracy, it still tracks my actual movements much much closer than that.

I think the Epic GPS works just fine as is. If your's doesn't work, then I'd return it for another unit. All the units that work, seem to work well from what I am hearing.

Just bought the Epic a week ago. All the Gps Navigation apps work fine even before the google maps update. This phone has unreal power and over all I think its the best and fastest phone on the market. I hit 4g in Pittsburgh and it was like hyper speed for the internet. I cant wait for 4g to be every where. It was faster than my wifi. Amazing.

My epic gps works perfect on google navigator i get a fast lock outside. But on google maps it is off by a block/next street parallel to it.

Another thing i noticed the epic gps does not get a lock inside my home what so ever. My sisters palm pre ,my samsung blackjack, and my iphone 3gs all get gps lock within a minute inside my home

However, as long as it works with google navigator im happy. As far as getting a gps lock inside my home, Just curious about that

Dude:

GPS wasn't really designed for use indoors....granted, it may penetrate some materials and structures, but it was never designed for that. Anytime you get ANY GPS signal indoors, you're either in a thin-walled structure that's relatively transparent to GPS or you are using "multi-path" signals that bounced around through the windows.

Don't expect GPS to work well indoors at all. Here, read:

I can say this person is either NOT a sprint Employee or a very low level one.

Sprint top support on Epic, the "Advanced Device" group is working on getting samsung to fix MULTIPLE epic GPS bugs on Epic , including at leas one severe one involving cache

The title is a bit sensational but not very.

All the serious reviewers doing in depth checks with diagnostic gps programs have all found problems. Can you name ONE review using Android applications for GPS diagnostics that have not found a problem?
Here is anantech which looked into the phone in depth:

"Dude," you are wrong. ALL modern smartphones locations work indoors.
Ones with correctly working location aplciaitons simply move through the most accurate to less accurate depending on RF conditions.

They attempt:
- full GPS; if not, then,
- hybrid using a marginal GPS signal plus towers; if not GPS, then,
- a series of decreasing accuracy tower uses, from the fairly accurate AFLT (doaable by most smartphones wthht contact to several towers, ie in most indoor locations) running through three or four methods, down to the bottom whihc is cell tower location.

So please don't misinform people. You can be in a concrete bunker with an Evo, A treo Pro, a Touch Pro 2 and your LBAs (your phones location based applicaions) will get location with no GPS, varying form 10 meters to 1000 meters depending..

My Epic's GPS will eventually lock on, but it takes several minutes every time. Using GPSTest, it will report actually seeing ~11 satellites, but 'using' 0. Finally after 3-5 minutes, it will start to use a few and eventually go up to using 9 or so.

It wouldn't be that big of a deal, except my iPhone 3G (what I'm replacing with the Epic) locks on in about 5 seconds, no matter if I've had the phone off or not. And that phone is 2+ years old. Certainly GPS technology hasn't reverted...

To be fair, thats not what he said. He said "GPS wasn't really designed for use indoors." which, as far as I know, is a completely true statement.

Now, plenty of GPS devices can and do work indoors, but there's no guarantee.

The problem with the Epic (one of them, anyway) appears to be one of sensitivity. Reports that the Epic seems to be 5db to 10db less sensitive then most other phones are pretty consistent. (I've seen this myself, check some of my other posts.) This is probably why the Epic will fail to pick up as many satellites (if any) as other devices in the same location. This is especially noticeable indoors, where the signal strength is going to be lower.

On the sensitivity note: I agree with another poster in these forums: The lack of sensitivity is probably a hardware issue and is unlikely to be fixed.

This isn't the first time someone has claimed that Sprint has acknowledged the problem and is supposedly talking to Samsung about it. Thing is, no one has provided any evidence of this other than "I spoke to someone that works for Sprint tech support and they said...". I'd be a lot happier if this acknowledgment was made in print or somewhere on the Sprint website / forums by an actual Sprint representative.

So, anyone have any links to support this claim?

It wouldn't be that big of a deal, except my iPhone 3G (what I'm replacing with the Epic) locks on in about 5 seconds, no matter if I've had the phone off or not. And that phone is 2+ years old. Certainly GPS technology hasn't reverted...
mine locks in 5 secs or so. acurracy is still not absolutely super but it does lock in less than 30 secs. and uses most if not all the sats in view. I think its area specific that causes some of the problems.

Don't you know we're all beta testers for Sprint, yeah my GPS isn't working perfectly either, i'm sure they will fix it soon.. What does IT have to do with the Thread?

I tried GPS (wireless off) the other day and it seems to track me using My Tracks pretty well as I walked back and forth about 20 feet in the parking lot.

I went for a 2 mile run today and also ran My Tracks. Wireless was ON this time. But, the tracks are pretty darn accurate so I think I had a GPS fix. It could tell which side of the 1-lane street I was running on.

I didn't say there isn't a problem. What I said is that some are having problems and some are not. Which is what leads to all the hostility and anger in these threads.

OK, I'm changing my tune. There is definitely a problem. I turned wireless off and drove around. I can see 8-11 birds in the sky and average about 8 of them being used for positioning. This is with GPS Test by the way. The SN ratio for them hang around mid 20's to low 30's, and never peaking above the high 30s. The accuracy....98.4 feet. Yup. It's a relatively cloudy day and granted, there is a forest fire burning about 4 miles from my house but still.

I then did a walk test in my parking lot. I slowly walked a square using My Tracks about 8m on each side. I set the resolution in My Tracks as high as possible. Here is a photo showing what My Tracks thought I walked vs. what I actually walked.

I can't imagine it being area specific. I don't know much about GPS or satellites in general, but shouldn't I have about the same view of satellites in Chicago that someone would have in say... Memphis or Omaha? Its not like we're on vastly different parts of the globe that you'd be able to lock on < 30 seconds, and it takes me 4 minutes.

And no, I'm not surrounded by buildings or trees or anything else that blocks my view of the sky. Like I said, it can 'see' the satellites, just doesn't 'use' them for a few minutes.

well look at satellite tv, when i lived in boston, i had dish network, no problem with signal, couldn't understand what people complained about. moved to florida and the dish goes out in every rain storm.

I didn't say there isn't a problem. What I said is that some are having problems and some are not. Which is what leads to all the hostility and anger in these threads.
Most likely the entire line has the same problem. Those in optimum conditions will get the good results posted here and in the other threads. Add in marginal conditions as some have been experiencing and the results become a little more iffy.

Through reading these threads and paying attention to a couple of specific posters here with obvious gps knowledge there is more than one problem with the Epic's gps. First one being the low SNR. Everyone is affected by this. Any other recent device that can be compared to will get you SNR in the low 40 range ( minimum high 30 for several) for at least one or two birds among the 8 or so in use when in optimum conditions. I havent seen one post of an epic reaching that number.
Based on this it SEEMS to be a poor implemetation of antenna.
The reason why this is so critical is once SNR drops too low, it will be below the threshold for which to phone to lock and make use where other devices still will function. This would seem to be a hardware issue.

The second problem is (seems to be) with the phone obtaining, or using, current almanac and ephemeris data. These give the phone the information needed to determine what satellites to look for and information needed to calculate the phones position. If the phone is not able to receive, does not update, or uses old information the phone will not be able to provide the location. This problem seems intermittent and a reboot appears to clear it up. Based on the reboot, this could be software related.

Much of this information came from this post All Things GPS for those who are inclined to persue in depth.

I am in no way suggesting 'I KNOW WHATS GOING ON' Ive gleaned my understanding, and I may be way off base, by those here with greater knowledge and been good enough to share thier viewpoints despite the hostility. As far as the hostility, too many are taking it personal that the potential top-dog device has flaws, and to some, VERY serious flaws.

That is my point though. I wasn't saying there is no issue with the GPS. I was saying that some people are having problems and some people are not. Saying "GPS doesn't work" doesn't really work in this situation. "GPS has issues", yes. "GPS doesn't work", no. Plenty of people have working GPS's on their Epic, or atleast working to their standards.

What these threads turn into is one said screaming "GPS doesn't work!" because theirs doesn't and another side screaming "GPS does work!" because theirs does. Half the posters seem to take it as a personal insult if someone has a different experience with the same item as them, whether it be a negative or positive experience. This thread has hit this pattern multiple times already. It's much better to state that some people have problems and some don't.

Does the Epic GPS have issues? Most likely. Samsung has already admitted the Galaxy S line has issues, and never really said the Epic was completely fixed (they said it was tested, not completely fixed).

IMO, for what its worth, maybe the OP's sensational title shouldn't be such a blanket statement. On the other hand, the pure enthusiast with experience with more than just this particular phone may well feel that the title is an apt description. An enthusiast isnt going to take into consideration that others may be satisfied with what he considers as subpar performance. You also have to consider that if the OP were in nominal conditions his gps may not have worked at all, and this exact thing has been reported on several forums.

You hit the nail on the head. No matter, the OP doesnt appear to be active in this thread any more, however a few others with the technical expertise have taken up the conversation. No reason they should take the hit for the sensational title. It is up to all participants to decide if they want to be objective and set aside brand or device loyalty, read up and actually take the time to try to understand what others are saying without becomming upset.

Just to be clear, Samsung has never actually admitted anything, but that is not so important in the short run. At least they promised to "optimize" the GPS generally. And on the Epic, they went further than just saying it was tested. They said it was "tested and validated."

Certainly, despite this statement, the Epic has some GPS bugs. But under the principle of Hanlon's Razor, it cannot yet be said that Samsung deliberately lied.

From what we in the user community know, and some have established objectively, the Epic's symptoms seem to be new and specific to the Sprint product. That does not mean the Epic still shares all the GPS symptoms of the other Galaxy S platforms. In my own testing and the reports of others' testing the Epic, I do not find a pattern of serious, actual inaccuracy. But I have seen that evidence when the other variants have been tested.

And, in my opinion so far -- with three weeks left on my 30-day trial -- the problems documented to date may not comprise a hard stop so long as they get fixed. Some official assurance from Samsung or Sprint committing to fix them might help keep some customers. (I already returned two Vibrants to T-Mobile and cancelled my contract renewal over the GPS issue as well as the vendors' less-than-complete commitment to stand behind the product.)

Wow, what a thread. Read almost all of the posts then just got tired.

I'll add this little tidbit for what it's worth. My GPS works fine outside. However, inside...not so good. My buddy is visiting and has the Motorola Droid and gets GPS in my apartment (apartment is below ground in a three story building). Mine, sitting 4 feet away from him, doesn't. No biggie. But compared to my former phone, the Palm Pre, this thing is a godsend. My Pre would "gestimate" my location within 3249 feet (actual number, using either just GPS or Towers) whereas this phone is within a couple FEET. So, I have no complaints.

I tried my GPS using Google Maps and it worked without a problem. I set the destination to my home using my Epic and my Garmin Nuvi 255. The Epic was spot on with my Nuvi except there were some occasions when the Epic picked a slightly different route but re-calculated the course and was again matching my Nuvi. The only other thing about the Epic was the voice directions weren't near as clear as my Nuvi.

I really don't need to use my phone for the GPS but at the cost of these phones it should work flawlessly for everyone.

OK, the GPS on the Epic is officially crap.

Here is a snapshot from My Tracks. The first run, the one on top, is from earlier this week with WiFi networks *on*. (edit: I meant wireless) It's surprisingly accurate.

The second run, the one on bottom, is the exact same run with WiFi networks off. (edit: I meant wireless) This needs to be fixed within 30 days or the phone goes back....what a joke.



Note: I'm assuming that the GPS lost signal or My Tracks stopped recording at some point in the second run. But the first part of the run should be exactly the same, and obviously it isn't.

I don't get it.

What is the big deal of having WFI networks on if it helps the situation? Obviously it looks like you got a perfect track that way.

Of all the tracks reported about the Epic GPS, this is the first one I have seen that make me cringe. This does not seem to be a simple problem with tracking accuracy. It is as if the second track started in the wrong place enteirely, then the whole track was offset accordingly. When the second track was run, what was the phone showing about satellite locks?

I doubt that toggling the "Use wireless networks" setting had anything to do with it, unless it was the first track that was in the wrong place! But obviously you would have told us if that were true.

Maybe it would help us if you uploaded the My Tracks tracks to Google My Maps and then posted a link to the actual tracks, instead of just posting an image.

Track 5 - Google Maps

Actually it's showing that GPS either didn't lock or it didn't start recording until partway into the run. But yeah it sucks.

I didn't look at the lock today. But yesterday I was driving around more or less the same neighborhood and I could see 10+ birds in the sky, using 8 or so. S/N ratios around 25-35.

Where do I start?

For one, I live in Colorado and like to go hiking. No cell reception in the mountains. I want to use this to track my hikes.

For two, I like to travel. Unfortunately, since I'm not on GSM I am pretty limited in where I can get data with this phone. Taking it to Europe as a GPS device is not going to work.

For three, as accurate as it looks, it's not as accurate as GPS would/should be.

Lastly, it's just the principle alone.

Thanks, I get that now. What is the setting your My Tracks for "Minimum Accuracy" ("Recording will be paused if your position is not at least this accurate")? If the accuracy of your GPS was FUBAR during the second run, which seems apparent, that would explain why My Tracks truncated the track.

I just did another walk test using My Tracks outside. Always had between 6 and 10 satellites *in use* during this walk, about a 1/4 mile long. It was all on a sidewalk and I held the phone out in front of me (instead of on my armband like I do with my runs)

By my rough estimation from looking at the graph, it was ranging between 3 and 30 feet off - averaging about 15 feet off. Not as horrible as this morning but it should be better.
