[Epic 4G General] APOLAUF:
I must say that I have zero accuracy issues whatsoever. I *do* have stale ephemeris data problems like nobody's business - cold-start mode won't help either if I'm connected to WiFi or 4G (though 4G seems to have better luck.) The software-reported accuracy issues are a hard-coded datum, which in the Captivate has now been removed.

If I don't exclusively sit on 3G, then either Hot-start or Cold-start are unreliable. If I *am* on 3G, then Hot-start pinpoints me exactly, and almost instantly. With cold-start, it takes a bit to narrow in, though the *initial* lock is often faster. Other times, I'll see (in GPS Status) that it has found all 10 satellites, but not locked - the ephemeris bug all over again. Disappointing to say the least. BTW, this is not fixed on Captivate - it cannot get a lock while on WiFi. This has got to be a software problem. Neither my Epic nor Captivate have any issues actually sticking to the satellites. If this were software, then the GPS itself would be unreliable *during* operation; not just initial lock.
[Epic 4G General] boomerbubba:
The SNR levels on the Epic do seem moderately lower than what other phones report. Theroretically this could be due to antenna design. The SNR level itself is a complex estimate by the GPS chip, not an objective reality being metered. So another possible explanation is that the SNR calculation is buggy. The estimated accuracy calculation is obviously buggy, always reported at 30.0 meters as if it is hard-coded. So there could also be a bug in the calculation of SNR, too. As for antenna design, I don't even assume that the Epic has the same antenna design as other Galaxy S phones, because its form factor is completely different.

In any case, signal sensitivity cannot explain the locking behavior, which has been isolated by user testing to be caused by bad handling of the cache of GPS almanac and ephemeris data. This is a bug.

Poor signal sensitivity could explain problems with actual accuracy. But like APOLAUF, I don't think there is a problem with actual actual accuracy on the Epic. The way to test that empirically is by plotting the recorded tracks in software such as My Tracks. If have done that with my Epic, for both driving and walking tracks, simultaneously with benchmark tracks captured by a known good device. I used my venerable G1, which has excellent GPS performance. The actual accuracy of the Epic is just as good.

The other GSM-based Galaxy S devices have had problems with actual accuracy, verified by many tests with My Tracks. But they are wholly different devices.

It is hard to tell from anecdotal reports in forums how accurate GPS performance is. Some reports of poor accuracy can be explained by poor locking. Some can be explained by pilot error. It takes controlled testing to get at the facts. Unfortunately, most commenters in forums, including this one, haven't a clue how to test the GPS rigorously.
[Epic 4G General] Djinn23:
IMO

First I have a co-worker who has been working with a developer and can get a GPS lock on his captivate super quick. To aide he is using the cell towers to get him a list of applicable satellites to his approximate location and gets a massive list of responding sats.

The next point is that I think that there is likely an issue with the Antenna . . but I do not think that is exclusively the issue. If this were strictly a HW issue then the issue would not be alleviated after a restart of the phone. There are multiple accounts that this is what is occurring.

Personally (and perhaps because this is my first true GPS phone) it is a minor inconvenience and doesnt bother me too much. . . . but is annoying and something that I would expect Sammy to go after. . . or at least acknowledge
[Epic 4G General] fooo1:
I've had the chance to Navigate a bunch of times now, and the locked on accuracy is certainly lacking. I'll be on a 10 lane freeway and it'll dump me into a road on the side of the highway, asking to reroute, before a few seconds later, it plops me back on the freeway. Geocaching was also painful. So the actual accuracy, after you manage to find a lock, is also not so good right now.
[Epic 4G General] boomerbubba:
How do you know how good the lock was in the first place? Did you use GPS Test to see the satellite-locking behavior, or just open Navigate? If you are only getting a minimal number of birds because of an underlying cache problem, that could show up as poor accuracy when the root cause really is unstable locking due to the cache bug.
[Epic 4G General] fooo1:
Usually I need to open GPS Status just to get to to download the assistance data.

But yah, either way, plenty of issues remain with latest firmware.
[Epic 4G General] boomerbubba:
How many satellites does GPS Status say are locked?

Also, have you tried the Cold Start settings workaround?
[Epic 4G General] fooo1:
I have warm start on (instead of hot), as I needed to use this outside of the network sometimes and cold start is not acceptable for that.

It was showing over 9 yellow satellites and I flipped back to nav before they turned green so not sure how many it locked on to. All of this is unacceptable to have to play with while driving.:)
[Epic 4G General] aero1:
To take your last point first, location based application and use of location data is a massively increasing part of the smartphone and android application base.

The fact that it is a connected device means it has more utility than any dedicated GPS device. So the GPS is extremely important

On your first point, this is a sprint phone, and Sprint localizes assistance data sent to its devices simplex, not duplex. Meaning that the factyou are accessing a tower in Cincinnati means you will get the assistance data for that region. That is why use wireless Networks claim as improving aGPS by Samsung was patently false, Epci does not send its rough location for the purpose of the getting localized assistance to sprints assistance servers. Sprint bases its assistance data on your voice connection region.

On the second point, while I agree with boomerbubba, that the SNR is difficult to compare, I think that secondary to the software cache issue, Epic has belwo average signal reception. I base this not just on the SNR, but slow walks into buildings with a couple of different devices. I am seeing the Epic generally drop satellites first. Driving I generally see the Epic holding a couple less satellites than my Navigon dedicated, then a treo pro I am testing with, and then an Evo we have. I do not think it is a deal killer but I think it is observable.

On accuracy in general it is hard to say. A lot of programs (and devices) compensate in different ways. Some software and modes of software snap you to street some do not. This affects perceptions of lateral accuracy. some utilize speed averaging prediction or even gyroscopes and g-sensors to affect perceptions of forward and back accuracy. Even beyond that firmware based mutlipath rejection, which is not strictly hardware, but which is difficult to tune can affect accuracy differently in differently situations.

I think we can all agree that Samsung needs to address this. I think Sprint knows there is an issue but I am not sure Samsung will actually do anything since they are already lying to customers about the utility if "use wireless networks."
[Epic 4G General] herzzreh:
Unfortunately this phone is going back... I love the screen, I love the physical keyboard but GPS accuracy isn't acceptable for me. :(

I've compared this phone and my "old" Evo using My Tracks - Evo is spot on, Epic was all over the place. Sadly this is a deal killer for me.
[Epic 4G General] boomerbubba:
On the SNR issue, I think you and I are really pretty close to a meeting of the minds. I was arguing against the other commenter upthread asserting without empirical foundation that all the Epic GPS problems are simply explainable by antenna design. Obviously the cache bug you have isolated is a discrete firmware issue, with qualitatively different behavior as soon as the cache is refreshed. That defeats the other commenter's speculative hypothesis.

I think any moderate signal weakness or sensitivity problem will manifest itself on the margin, as an aggravating factor when satellite signals are attenuated or bounced around as multipath by the environment. But when GPS Test is showing 9/11 satellites, even while reporting moderately lower SNRs than another device, I doubt there is much difference in accuracy.

If Sprint would just fix the two bugs that are unambiguously repeatable -- the cache bug and the bogus 30-meter estimated accuracy -- I would be satisfied. Lately, based on comments from some users in the Sprint forum reporting stonewalling by Sprint customer service, I fear that nothing will be done and Samsung will just move on to its next big thing. That would be an incredible tragedy, because these two discrete bugs can't be that hard to fix.
[Epic 4G General] aero1:
I think your logic on that, and more importantly perspective on the relative issues, is sound.

I am also not optimistic Sprint has the juice to get Samsung to fix any of the issues. I am not a consipracy theorist, but I think it is in the realm of possibility that the hardcoded 30 meters is there intentionally.
[Epic 4G General] APOLAUF:
The Captivate also exhibited the hard-coded 30m accuracy. As of the latest update, that has been fixed. On my Captivate, I can now see accuracies less than 2m or better. It would stand to follow, imho, that the same fix could come to us (or so I'm hoping.)
[Epic 4G General] aero1:
yeah that makes sense. I was just noting that some programs need a certain accuracy, and by hard coding it, a manufacturer could essentially cheat. I don't think that is why the hardcode is there, but it is not impossible
[Epic 4G General] APOLAUF:
That's a good point, I too wonder from where such a seemingly-arbitrary figure came.
[Epic 4G General] Shane112358:
I bought the Epic on launch day and returned it at D+30 due to the GPS issues. Got an EVO with the hope that the Epic would be fixed by D+60.

So right now I'm at D+58 and I need to decide what to do. It sounds like the GPS fix has not at all been addressed on the Epic, is that correct?

Also, it's my understanding that the upload cap has been fixed, right?

Thanks :D
[Epic 4G General] jojo08:
I'm kind of in your shoes, i'm coming up on day 30 w/ epic soon and need to decide if i want to return and try out the evo, i like the epic but all these little things add up (gps issues, drm processes, time w/o signal, still no froyo!), if i do return the epic do i still get 30 days w/ the evo to decide which one i like better?

the upload cap has been removed but it seems like i get inconsistent download speeds after that update...

also using both phones did you notice any stand out pros/cons between the two?
[Epic 4G General] Shane112358:
Yes you can get a different phone and then return that one for another one within the next 30 days if you wish. Others on the forums may say or have experienced otherwise but I've talked to multiple CSRs and have had notes added to my account to this effect.

Random thoughts:

* GPS on EVO is much better

* EVO is a little slower software-wise

* EVO Sense UI is slightly better than TouchWiz but there are some things I miss (SMS or email directly from lock screen, contacts pics were better on Epic, etc).

* Epic screen is definitely better but don't really notice it in everyday usage

* Battery life on Evo is slightly worse but not too bad

* Surprisingly do not miss the physical keyboard AT ALL. I think using multitouch is actually faster on the Evo than the physical on the Epic, at least for me.

* Love the dev community on the Evo.

* Evo feels more "solid" probably because of no moving parts

Basically if it weren't for one major problem I'm having with the Evo (I can't d/l attachments >1MB from my Exchange server) I wouldn't even be considering going back to the Epic. But I really need to get work attachments and it's driving me crazy. The Epic is definitely faster and snappier in everyday use but it's not a huge difference at all.
[Epic 4G General] boomerbubba:
Correct. There are ways to work around the worst of the GPS bugs. But if you want a GPS that just works, the Epic is not there yet. Nor has Sprint or Samsung publicly acknowledged that there is a GPS problem.

Why do you want to watch porn on a 4" screen when your computer has a bigger screen?

But as for your question, all depends on the format of the video. Try a different video app as your default and see if it works. If not, I guess you'll have to go back to Eclair.

I also have no problems with video playing, RockPlayer runs very well on the Captivate during saved file usage, damn near any format I could throw at it....Except for streaming files. (3gp).

are you still using the original SPB shell? I suggest you follow instruction in this forum to strip down your phone and install the new SPB shell 3.5.5, it is much more stable then the "panel version"

I forgot how the original was with MR2, but i guess it is similar, just hit the right corner menu button, and you should see change background option there.

Beware that you cant change the background for Professional View, it is always black by default.

[Vibrant General] Skullpuck:
Phone: Samsung Vibrant

PC: Windows 7 64-bit

Latest drivers from xda installed for phone.

I've tried for over 2 hours now and rooting does not work for me.

It will not push the update.zip to my phone and my phone does not restart.

I have followed the instructions in the Rooting forum to a T.

I've turned on USB Debugging. I plug my USB cable in. My drives show up in Windows Explorer. I then run the T-Mobile Vibrant One-Click Root application in admin mode.

I click on One-Click Root and the shell runs. It says my phone should be rebooting but nothing happens on my phone. Nothing gets copied and the phone does not reboot.

Any ideas?

EDIT: I looked in the rooting thread more and people have been posting about ADB. I've checked this in my Device Manager and I have "ADB Interface" listed there with no ! on it. It says it's working properly.
[Vibrant General] biigreen:
Are you mounting the USB??? To get adb or other apps to work you can not have the USB connecte mounted. You said you can see it in windows explorer so I am assuming that you mounted the USB.
[Vibrant General] Skullpuck:
The mounting is happening automatically. I plug in my USB and it mounts and turned on USB Debugging. Not sure why it's doing it automatically as it never has in the past.

I'm not sure what you mean by "you can not have the USB connected"

If I can't have the USB connected then how do I do this?
[Vibrant General] watcher64:
You cannot have the drives mounted , if they show up in windows , adb will not work ..

Did you happen to install the winamp beta for android? , it mounts the drives.
[Vibrant General] Skullpuck:
Yes... I did.

So I uninstalled Winamp Beta. Removed the USB. Plugged it back in. This time the drives did not mount.

I tried to run the One-Click again and nothing happened.

Why don't you just download the. Zip file, rename to update.zip, move it to the root of your internal sdcard, reboot into recovery, then reinstall packages.

Dude,

This is what I follwed and it worked 100% for me:

1. Download update.zip file on PC

2. On your Vibrant, go to Settings > Applications > USB Settings > and select Mass Storage.

3. Connect your Vibrant to your computer, and mount as a mass storage device by pulling down the notification bar at the top of the screen.

4. Back on your computer, look for a new drive. We’re looking for the Internal Storage, not the External, so make sure you open the drive that does NOT have the Avatar movie in it.

5. Copy (drag and drop) the update.zip file to the Internal Storage.

6. Turn off the phone.

7. Hold down the volume up and down buttons while turning the Vibrant on, which will bring you to the recovery mode.

8. To navigate in Recovery, use volume up and down to move, and Power button to select. Select ‘Reinstall Packages“

9. After installed, your phone will reboot, and will have the Superuser app, as well as Busybox installed.

10. You’re Rooted!

[Vibrant General] Skullpuck:
Worked great until Step #7.

I tried turning the phone on holding down both the volume up and volume down buttons but no recovery console.
