thought you guys would want to know - samsung released an "unofficial" firmware update for the Vibrant that actually fixes the GPS issue as well as a number of other quirks / issures

i know it's too early to declare complete victory, but from my post on the Tmobile forum where it was posted - the firmware is also linked in the post, for those interested in extracting the GPS files:

http://forums.t-mobile.com/t5/Operating-System-Software/UNofficial-T-Mobile-Vibrant-update/td-p/469275

"well, thought i'd throw this report out there - got the rom flashed this morning ............... - anyway, did a 9 mile drive, long circuitous route with a multitude of turns (somewhere in the 25-30 turns range), speeds from 30 - 60 MPH, and the only "glitch" in the MyTracks log was one corner was clipped as if i had driven across 10 foot of my neighbor's lawn,

other than that one deviation, it was flawless.

accuracy was so good, it actually showed me at one corner of my lot as i left, then when i got to the far corner, it had me located EXACTLY where i was - unheard of accuracy before this rom

GPS, outside showed 11 to 12 sats in view, with 7 to 8 locked - i even got sats in view inside the house which i had NOT been able to do before, at all

overall, i'm pretty happy, no, make that ecstatic over the way it tracked - i had gotten pretty cynical samsung could do it"
[Epic 4G General] APOLAUF:
It still remains to be seen whether or not this fixes the ephemeris !flush bug.
[Epic 4G General] boomerbubba:
FWIW, I have been kibitzing in the new Fascinate forums, where there are reports of similar problems with loss of locking ability after day or so. Also, a couple of those victims have confirmed that rebooting is a workaround for the problem. That is consistent with the behavior on the Epic.

So my current theory is that this may be a new bug that Samsung introduced with new firmware it delivered to both Sprint and Verizon. Perhaps it is even deeper, and it is a bug in new firmware that Broadcom wrote for Samsung.

So it will be interesting to see if this problem does propagate to the update delivered to T-Mobile and AT&T.

But meanwhile, larryccf's report sounds like good news for the Vibrant. I left T-Mobile for Sprint largely over dissatifaction with how they handled the GPS issue. If it is actually fixed there, without the new bugs that afflict the Epic, I might jump back -- especially in view of some other Epic issues such as bad network performance. (Overall, I had better speeds on T-Mobile.)
[Epic 4G General] smashpunks:
What's the flush bug.?

I can say the GPS is fixed on the vibrant. I'm on the new firmware and its working great. Yours will be fixed too, I'm confident because I wasn't till now.
[Epic 4G General] APOLAUF:
The !flush bug (sorry, I had to nerd it up a bit - translated, means "not flush" bug) means that the ephemeris data isn't flushed and updated when it's supposed to be. This means the GPS has to lock on essentially without assist. Even then, that doesn't always work properly due to other issues with GPS. Glad to hear your Vibrant is performing the way it should. Try it again after resting it overnight, see if it still works just as well.
[Epic 4G General] dwyw42:
I don't remember if I reset my phone yesterday before or after I was playing with the GPS, so I just ran the GPS this morning and closed the gps app. I'll let it sit till tomorrow morning and let you know how it works.
[Epic 4G General] genax:
i have owned the epic since the day it came out. i noticed that gps had a hard time locking with google maps. however it locked on quickly and consistently with the program called cardio trainer. can someone explain to me why? it makes no sense to me hehe. how can a exercise program work without problems locking onto gps yet google maps has a difficult time locking on?
[Epic 4G General] dwyw42:
Ok... interesting result this morning. I started GPS Test yesterday morning and got good locks, then made sure all GPS apps were closed and not running in the background until this morning. Right before I went to work, I opened GPS Test again and got 0/8 sats (all grey but in low to mid 20s SNR-wise). After a quick "oh crap" I closed and re-opened GPS Test to the same result. Each time I only gave it about 10 seconds since that's the longest it took for a good lock before. Then I closed GPS Test and ran GPS Status, which locked 7/7 in a few seconds, so I went back to GPS Test and it quickly locked 8/8.

I'm not sure if I ran GPS Status since the last reboot, so does running a different GPS app for the first time since reboot force the ephemeris to refresh across all apps, same as rebooting the phone? In any case, I'll run the test again tomorrow morning, just using one GPS app and leaving it open to see if it ever recovers from 0/8 on its own.
[Epic 4G General] APOLAUF:
Is it possible that the ephemeris data has more trouble updating over WiFi, and/or, relatedly, does the phone pull assistance information ALWAYS over 3G regardless of WiFi state? I ask this because I notice consistently worse performance when I have WiFi always enabled vs. when 3G is the only active data radio. Though the phone eventually fails to acquire a lock regardless, it seems to have a lower chance of failure when WiFi is off before I try to get a lock. Perhaps I'm seeing things.
[Epic 4G General] aero1:
There are some things that can inadvertently clear the cache. We have had users with the bug over the past couple of days saying the update fixed it. But of course the update would flush the cache with a reset eve if it had nothing to do with the GPS bug -- and that is exactly the case.

This is what makes the forum responses from people not doing controlled tests (not you but others) stating the GPS is fixed or works is not helpful. The bug is there, it is still there.
[Epic 4G General] J3ff:
It absolutely is . did the update last night, gps locked right away OF COURSE.

This morning , 12 hours later, gps would not get a lock.
[Epic 4G General] dwyw42:
Well, I just had another interesting result. I applied the update yesterday morning, then used the GPS + navigation while running a few errands. This morning while I was out, I started GPS Test and it displayed the no lock bug - 0/10 satellites locked with 2 or 3 of them at 30 (dB?) SNR. I let it sit for 30 seconds and it would not lock. I closed GPS Test and reopened and let it sit for another 30 seconds and still no lock. Then I closed GPS Test and opened GPS Status - bam lock on 8/9 sats within 2 seconds. Closed GPS Status and reopened GPS Test and it locked right away.

Could GPS Status be force flushing the ephemeris somehow?
[Epic 4G General] tommi_han:
I definitely noticed gps update faster with gps status and after using that app. Especially with google maps after right after using gps status
[Epic 4G General] aero1:
Yes some ways of applying or even installing apps can artificially clear cache, as can updates, or different uses of GPS.
[Epic 4G General] J3ff:
Was out on the water today, phone could not get a lock at all, until I rebooted. What is this Epic , a windows PC? :)
[Epic 4G General] APOLAUF:
Thought I'd post an "interesting" development. By virtue of being the OP, I clearly have had GPS issues with this phone, even post-update. However, after about 40 hours of uptime without reboots (as given by system uptime), I have had *flawless* GPS locks within 10 seconds, every time, over 3G network access, the entire time. I've used WiFi from time to time, but every time I open maps, I make sure it's off, with a few rare exceptions. It worked great!

Until I rebooted, just once. It went back to being crap, and needed two reboots to clear out. Not even clearing the ephemeris worked in GPS Status. The problem struck when I exited GMaps, and the GPS icon continued to pump away - necessitating the reboot in the first place.

In any case, I'll see what the next 40 hours brings, perhaps those who are having good luck with GPS lock are simply experiencing that out of random probability?
[Epic 4G General] APOLAUF:
Alright, so yet another update, after 30 hours in this time, I still have flawless GPS locks, one after another. Still not sure what cause the little "the GPS won't turn off" snafu from the previous post, but, provided I have WiFi off before I open up GMaps or another GPS-dependent app, I always get a lock within 10-20 seconds now.

Aero1, any such luck? I'm beginning to wonder if, infact, the update fixed *something* that I wasn't noticing before? Or are the GPS fairies pleased with me and thus granting me clear horizons? :)
[Epic 4G General] aero1:
Apolauf,

Boomer and I have been testign warm and cold start for some time. warm helps but cold does fix it. The caveat, as I mentioned before is that it will hose ttff when off of network.
[Epic 4G General] APOLAUF:
Thanks for the reply, Aero1... a quick question though - is cold start the default? (I seem to remember that in GPS Test, none of the options are selected by default, which is why I ask... I never changed any settings whatsoever.) The only change has been the update - GPS working ueber-sh!ttily before, and spectacularly now.
[Epic 4G General] boomerbubba:
The default is hot start.

FYI, I did have one other problem while running Cold Start yesterday: When the lock process was running under the GPS Test app, I also opened GPS Status. This usually causes no problems. But this time the phone froze up entirely and I had to reboot. This freezing/lockup problem while starting the GPS, which I had occasionally in the past and which some other users also report, may be a separate complication. I think I have seen it before when opening SpeedTest, which runs the GPS upon initialization. I do not think Cold Start is a cause of that problem.

Right now, I have effectively ceased testing the Cold Start workaround for a few days. Sprint tech support yesterday had me execute another GPS utility, which I believe just reset the cache by other means, and asked me to report back in a couple of days. So I also reset to the default Hot Start for purposes of that test to avoid introducing another variable.

I do not really expect this reset to have anything more than a temporary effect, but I am going through the motions with Sprint as I approach the end of my 30-day trial. (I also have reported the 3G upload problem, which is the more serious defect as of this moment. I am still leaning toward cancelling over that issue.)
[Epic 4G General] aero1:
They had me do that very early on. made a difference for a short while as any one time forced removal of cache no difference. In early September some people on android forums were told to do this, reported successes and came back to report return of the problem.

About one week into cold start I am still at zero problems with the two epics I have enables with cold start and the intermittent seeing of no sats or seeing them and not using them with the stock one.

cold start is averaging a 5 second aGPS fix.
[Epic 4G General] aero1:
Update: still zero problems with the aGPS on handsets using cold start and intermittent problems with the one I have on deault (warm)
[Epic 4G General] APOLAUF:
Possibly a stupid question, but does it work well with WiFi on with cold-start set?
[Epic 4G General] TheMostToys:
I'm six days in to the cold start workaround and I still have problems. As a matter of fact, I just tried to use my phone to find a place for lunch. It was embarrassing, the whole time at lunch I took a bunch of heckling from the people I was with. Even when we returned to work, the damn phone still didn't have a lock. Useless POS.
[Epic 4G General] J3ff:
Yup.

Same crap for me. I talk this phone up for weeks.....and it cant even give me directions at 3pm on a friday.

Even more worthless is that I reboot the phone and it takes a full 3 or 4 mins to get back up and running and then DUE TO CRAPPY UPLOAD CAPS it won't even display the MAP !!
[Epic 4G General] aero1:
Toys and Jeff:there are other GPS problems affecting Epic. Don't forget we are seeing poor SNR reporting on the Epic. there is some question on that with some believing that is irrelevant and some like myself believing it harms aGPS.

my results are as follows: we were experiencing an average on one failure to lock in perfect conditions per day on our three family epics, and none, I mean none in good conditions, with the workaround applied.

cold start of course is dependent on network coverage as is noted in the detail of this workaround. I notice both of you are saying your 3g performance is not good (I mean outside the upload cap issue). Any such problem would not be good conditions for aGPS in any case as you would be locked into kicked into standalone/autonomous with no cache.

The coldstart is not a fix, but a workaround, a nd one that shows problems with the agps as released by Samsung, and makes it generally less of a problem as long as you have a a data connection .

While the testing by Boomer and myself indicates it is failure to see cache as old and invalid, or failure to clear it if it is, the actual failure mode in some cases of failrue to aGPS lock, may in fact be poor data performance as well or in some cases.

So this is not a fix of all GPS problems, it is workaround of the one I found most vexing. i still do find problems. Like today I was driving in considerable cloud cover and my Epic was locking 3 to four sats. decided to on my next trip out this afternoon, use a Palm Treo Pro and a old navigation GPS in the same position it the car along side the Epic, and the Epic again had 3 to 5 sats, and the pro averaged holding 6 to7 an the navigon dedicated seven to nine.

So we are not saying this is the fix, it is workaround for one issue-- and one that confirms that Samsung screwed the pooch on this devices GPS.

APOLAUF: I would welcome your tests on wifi. please let us know how you are configuring to check. there are some things to look out for. there is some question whether the gps is workign at all in airplane (perhaps you can answer that). also almanac and ephemeris are mostly localized, and they need to be local, by tower (they are on sprint which is why turning on wireless networking has no positive affect). So that opens the question of whether through a wifi connection the assistance servers can know where "local" is. Please do check and let us know!
[Epic 4G General] thedevilslettucemd:
Unfortunately, I have applied the Cold Start fix and still am unable to get a lock no matter how many times I reboot This is the second epic i've gone through and I live 45 mins from both radioshack and our local sprint store. Is there something i'm missing or am I just extremely unlucky.
[Epic 4G General] aero1:
I pmed the only people sayng it wasn't working on other forums and they all had wireless networking on, which of course can screw up aGPS usage since the system is attemtping that method.

Is use wireless networking off on location? It should b off when using aGPS.
[Epic 4G General] APOLAUF:
Okay, so I've just confirmed after 2 days that aGPS does *not* work over 4G. The *only* way that the GPS can apparently get updated ephemeris, at least on my device, is over 3G. Not over WiFi, not over 4G. How f-ing stupid is this already? If I reboot, no dice. I can clear data away all day, no dice. I *have* to shut off WiFi/4G and then it works instantly. Otherwise, it sits there sllllowly getting a fix over a period of 5-10 minutes, even with warm start enabled. Do they not have testing labs for this kind of crap?!
[Epic 4G General] jirafabo:
Just dropping in my experience if it will help anyone.

About a month ago I switched to cold start from hot start and I get a lock in about 5 seconds every time. I don't even consider having a gps issue anymore. I use the GPS on my Epic about 5 times a day.

I don't usually have Wifi or 4g on as I'm in my car when using GPS. I've even used it for geocaching a bit, which requires spot on gps signal and its been great.
[Epic 4G General] kevyli85:
GPS not workin with 4G is the biggest issue for me. On the Evo I could be on the phone and use google maps at the same time. Now I have to tell the person on the line to hang up so I can get a signal, then call back...
[Epic 4G General] boomerbubba:
I'm not completely sure because I have not tested this rigorously myself. But you may be right. Because I heard anecdotal reports about 4G weeks ago, my habit in general use of GPS is to have the Cold Start setting enabled, and toggle 4G off before using GPS Test to get a lock. Then I open Google Maps, or whatever app I need, and turn 4G back on. Lately I have been rebooting my phone frequently for other reasons and also playing with the GPS Status refresh, so my results can get complicated.

So I know I've seen a matrix style boot animation for other phones but is there one for the Dinc? If not is there anyone that wants to make one or port one from another phone =) ?? I have no idea how to make one or port one myself. Also I don't know if it matters but I am on Sky Raider 3.0 RC3 (are all boot animations compatible with all roms?).

Yes, any boot animation made for the Incredible will work no matter what rom you have on it. The only differences are the file locations for the boot animation & sound on 2.1/2.2 are different from each other.

Awesome, I got those files downloaded but I can't figure out how to get them to work...

[Droid Incredible Q&A, Help & Troubleshooting] jskolm:
You need to put the file in /system/customize/resource and rename it to VZW_bootanimation.zip
[Droid Incredible Q&A, Help & Troubleshooting] Hatman41:
It depends on your Rom as to where you put it. I use SkyRaider 3.0 RC3 and I have to put it into /system/media and you also need to name it bootanimation.zip

Prefect, thanks I am using sr3 rc3 so that's exactly what I needed!
[Droid Incredible Q&A, Help & Troubleshooting] taihard:
So for those who want the set up like I have it, get which ever color you want from the link above (I use the blue) and you can also grab this audio file (matrix theme song I got off of mabilo ringtones app) and put them in your /system/media folder.

**Note, this is for people rockin the sky raider roms. Also make sure the zip file is named bootanimation.zip and the audio file is android_audio.mp3 (not sure if it has to be that for the audio but that's the way I tested it and it works).
[Droid Incredible Q&A, Help & Troubleshooting] BaronofBlood:
Is there anyway to combine this with the new Incredible boot animation? I think that would look so cool with the red matrix boot, then the new Incredible boot. Excellent job by the way, the animations are top quality. I've attached both animations for anyone who may know how to do this.

[HD2 General] tunppi:
I have been wondering what is this 576mb RAM b******t?

when I open Coreplayer, Resco explorer, do some opera 10 surfing it says 63-65% RAM used, then if i try open some small program like calculator or anything it ends up in error, or if I open album it says not enough memory.

Using 2.12.50 radio, newest energy ROM, this same has occurred in EVERY ROM and EVERY RADIO ive tried.

So i say that is totally real getting more RAM.

65% of ram used is not 100% I can tell you.

Haven't checked real usage in mb but this annoys me.

why add that to ROMs when it doesn't do anything good other than look better having less memory used?
[HD2 General] samsamuel:
and 35 - 37% from 576 isn't 128meg either, so if it was just a trick(which it isn't) your numbers still wouldn't add up.

you have a different issue.
[HD2 General] rumpleforeskin:
the album out of memory is a bug caused by having opera open at the same time.

do you have a reason to believe that the rest of your problems are memory related?

the 576 hack works fine and is real
[HD2 General] M3PH:
I have the exact same setup as the OP and guess what? i have no issues at all with memory usage. I have no errors and i have even tested his senario on my phone and got nothing but pure bliss and speed.

Dude, your problem lies elsewhere. Next time do some proper testing before you go shooting your mouth off. Only makes you look silly.
[HD2 General] tunppi:
hmh. Seems that I have to do some (lots) testing how much memory I can use etc.

Can hspl version have any effect in this?
[HD2 General] samsamuel:
no, it shouldn't.

your issue has been raised several times, and i remember seeing it in my old phones thread too, its more a windows mobile glitch than anything hardware.

for me, i'd back up and hard reset.
